Brian Halligan on What It Takes to Be a CEO Now That Starting a Company Is Easy and Scaling One Is Hard

Open on YouTube ↗
Overview

Brian Halligan co-founded HubSpot and ran it as CEO for about 15 years. He is now Sequoia's in-house CEO coach. He runs peer groups of founders, does one-on-one coaching, and hosts a CEO-focused podcast called Long Strange Trip. Lenny Rachitsky invited him on as someone who studies the CEO job closely. The conversation keeps returning to one tension that Halligan puts in his MIT course syllabus: starting a company has never been easier, and scaling one into a durable, high-impact organization has never been harder. His answers mix hiring tactics, a framework for judging founders, predictions about how AI will change go-to-market, and a set of "Halliganisms," lessons he drew from mistakes at HubSpot.

A "perpetual state of constructive dissatisfaction"

Lenny opened with a phrase one of HubSpot's board members used to describe Halligan: a perpetual state of constructive dissatisfaction. Halligan said he took it as a compliment. He sees the same trait in the fast-growing CEOs he now coaches. They rarely pause to take stock of what they have accomplished and stay focused on the end state.

He also said he has been surprised by how humble this generation of CEOs is. "Humble" was not the first word that would come to mind for his own generation, in his view, and he has been impressed by the difference.

The kids table and the adults table

At Sequoia, Halligan gathers CEOs into two groups. The "kids table" is about 15 CEOs of companies under 100 employees. The "adults table" is about 15 CEOs of companies above that size. He splits them because the problems at each stage are very different, although they rhyme a lot within each group.

When Lenny asked what distinguishes CEOs who graduate to the adults table, Halligan said the adults mostly want to talk about their executive team: how to build it and how to design the next layer of the org. He estimates they spend about half their time recruiting and interviewing. He remembers this from HubSpot's own growth, and says it surprises CEOs to discover that their job has become mostly interviewing and hiring.

He thinks most people, HubSpot included, are bad at it. CEOs overrate their ability to interview and their gut feel, and underrate a high-quality blind reference. He cited MongoDB CEO Dev Ittycheria, who told him that across roughly ten years as CEO, about two C-level executives turned over per year. Halligan didn't track HubSpot's number but suspects it was similar. His own rough guess is that at least half of C-level hires are gone within 18 months.

Hiring tactics: reading the board deck, blind references, and "spiky" candidates

Halligan admitted that even after many years, he still overrates his own interviewing ability. He offered several practices he considers better than the standard walk-through of a candidate's background.

The first comes from Parker Conrad. Before a C-level interview, Conrad has the candidate sign an NDA, sends them the latest board deck or memo, and schedules a half-hour conversation about it. If the candidate is purely complimentary, Conrad treats that as a major red flag, because he wants someone who will challenge him rather than a yes person. Halligan likes this as a way to see how someone thinks and how they will interact with you. He also recommends working through a problem together at a whiteboard.

The second is taking blind references seriously: find someone you know who worked with the candidate. From receiving many of these calls, Halligan says he can tell when the caller has already decided and is just checking a box. A caller who asks only for strengths and weaknesses has usually decided. The questions he finds revealing are harder ones. Would you enthusiastically rehire this person for that role? On a scale of 1 to 10, how likely are you to try to hire them back from me later? Were they in the top 1% of people you worked with? The top 10%?

The third is a change HubSpot made to how it read interview panels. Say one candidate for head of engineering gets four scores of 4 out of 4 and four scores of 2 out of 4 from eight interviewers, and another candidate gets 3 out of 4 from everyone. HubSpot almost always used to hire the consistent 3, the person with the fewest weaknesses. It switched to favoring the "spikier" candidate with real strengths and real weaknesses, and Halligan says its hit rate improved. HubSpot also shrank panels from about eight interviewers to about four. He noted a recent head-of-product hire was interviewed by only four people, and he thinks that worked.

His last piece of advice is one he says no one follows: hire slow and fire fast. Most people do the opposite.

Beware the big-company hire, and build like the 2004 Red Sox

Halligan called the big-company executive a mistake he made and says current CEOs are making too. A 50-person company hires someone with a fancy title from ten years at Microsoft. The result is a large impedance mismatch. The hire expects a company that has its act together, and a company of 50 or 500 people usually doesn't. HubSpot hired many people from Salesforce, Google, and Microsoft, and Halligan described attrition among them as essentially 100%.

Lenny mentioned the pattern of companies cycling through a McKinsey cohort, then an Apple cohort, then an Amazon cohort. Halligan said the McKinsey version "never works." His reasoning is that founders are, almost by definition, skeptical of conventional wisdom and unhappy with how some part of the world works, while someone who chooses to work at McKinsey tends to be conservative in outlook.

His alternative model is the 2004 Boston Red Sox, a team he now partly owns. That team broke an 86-year championship drought with a core of homegrown, high-quality, inexpensive players from its farm system, plus a few well-paid veterans such as David Ortiz, Pedro Martinez, and Curt Schilling. Halligan's point is that the mix worked and the culture held. Companies underrate homegrown talent "almost across the board." You don't want an entire team of been-there-done-that hires, and you don't want none. He noted that about half of HubSpot's management team has been there a long time, and pointed to Apple as another company with many homegrown leaders.

On how to act on this, he said an outside candidate usually interviews well, looks shiny, and hasn't shown you their warts, which you can only find through good blind referencing. So if an internal VP and an outside candidate are close, he would give the internal person the shot. He mentioned that Brian Chesky has argued companies over-rotate toward experienced outside management and delegation. Halligan thinks Chesky is mostly right, but observes that most CEOs he works with still follow the standard playbook of hiring heavily from outside.

The LOCKS framework for evaluating founders

Asked whether great CEOs share specific traits, Halligan described the rubric he uses when evaluating founders for Sequoia. He calls it his "LOCK" algorithm and added an S during the conversation:

  • Lovable. He means inspiring followership rather than being nice. Steve Jobs may not have been lovable, but people wanted to follow him. Halligan's test: would a 28-year-old version of himself, fresh out of business school, crawl across broken glass to work for this person?
  • Obsessed. He is wary of founders who came up with their problem six months ago. He prefers deep founder–market fit and evidence in someone's life of going obsessively down rabbit holes.
  • Chip on the shoulder. He says he wouldn't have come up with this one himself; it is a Sequoia idea. Nearly all the founders have one, sometimes "a boulder," and he says he has one too.
  • Knowledgeable. They know the domain deeply.
  • Student. He named Winston Weinberg of Harvey, James Cadwallader of Profound, and Gabe Stengel of Rogo as deep students of the game. They constantly learn from him and from peers and also study history. He compared them to LLMs in how they keep absorbing information.

Lenny added a trait from his own research: extreme ambition, meaning an attempt at something most people would call crazy.

Born or made, and what founders must learn

Halligan does not think anyone can become a great CEO. He described a new kind of founder he calls the "five-tool" CEO, borrowing from baseball scouting, where a five-tool player who can hit, hit for power, run, catch, and throw is extremely rare. Bret Taylor is his example: someone who can code, has taste and vision, can sell the product, and can convince employees. Halligan says there are now several of these in Sequoia's portfolio, and he didn't see many before. In his view, neither Steve Jobs nor Jeff Bezos fit that profile.

Lenny suggested AI might help CEOs fill their gaps. Halligan was skeptical about the hard parts. A brilliant developer still has to convince investors to fund them at a high valuation, persuade top people to leave OpenAI and join them, and win over a skeptical Fortune 500 buyer. He thinks the effect may run the other way: "mere mortals" like himself, who can code a little, will suddenly be able to build things.

He listed several skills most founders have to learn. They must give constant positive and negative feedback, which feels unnatural to someone in their late 20s who has never managed a team or even captained a sports team. They must develop a good BS detector, because employees and outsiders are always trying to sell to them. And they must learn to inspire. His example was Winston Weinberg, who was a lawyer for a few years before founding Harvey and had never needed to inspire anyone.

Of these, feedback is the most common challenge he sees. Many CEOs are working through the same hard conversations. One is asking a co-founder who runs product and engineering to step into a CTO/"labs" role so an operator can be hired to run the engineering machine. Another is "layering" an early sales hire who built a team of ten but can't define the sales profile, unpack the process, or forecast accurately. Halligan calls these conversations uncomfortable and "unnatural for homo sapiens," and says the best CEOs study how to have them and get good at them.

What helps most, in his experience, is peers. He can weigh in at the kids and adults tables, but it is more effective when other CEOs do. "Misery loves company," he said, and the groups serve as a safe space.

Why starting is easy and scaling is hard

Halligan explained the syllabus line with an analogy from his own life. As a kid, a drugstore offered four or five toothbrushes. By the 1990s or 2000s, Amazon offered four or five thousand, made by thousands of companies. Making things got much easier. AWS did the same for software companies around the time HubSpot started, around 2006, and he expects the current jump to be even bigger. He predicts the number of companies formed will "mushroom" over the next ten years, as it did over the last ten. The result is so much noise and competition that standing out and accelerating is harder than ever.

Lenny framed this as largely a distribution problem. Halligan agreed and added that founders didn't grow up doing distribution. Scaling becomes a learning game, and the ones who learn fastest do best.

27:50

Why enterprise sales may be the last white-collar job AI replaces

Halligan had tweeted that sales may be the last job AI replaces. Inside HubSpot, he said, AI is working "incredibly well" in software development and customer support, and is starting to work well in legal. On the go-to-market side, progress has been slow beyond support, with perhaps the BDR role as the first to change. He believes traditional enterprise sales, built on trust between "two carbon-based life forms," will be very late to go.

He does expect the go-to-market funnel to be turned on its head. When HubSpot started, buyers searched Google, clicked a blue link, explored the website, filled in a contact-sales form, and waited for a rep. He predicts buyers will instead start research in ChatGPT, Gemini, or Anthropic's assistant. These tools already know everything on your website and about your competitors, so buyers will arrive much better educated and websites will matter less. He expects homepages to feature a high-quality avatar that knows the product, company, pricing, and packaging and can hold a real conversation. That conversation would be stored and scored in the CRM, and a human rep would follow up for considered purchases. On every sales call, the rep would have an all-knowing AI sales-engineer avatar instead of waiting for a human SE.

He tied this to what he wants as a knowledge worker. He has a Delphi clone of himself that he likes, and he wants it connected to his email and meeting-notes tools so it knows everything about him and can join meetings as a participant rather than a note-taker. He predicts every knowledge worker will have something like this in three to five years. Lenny compared this to the popularity of the personal agent project Clawdbot, since renamed. When Lenny asked if anyone was doing the homepage avatar well yet, Halligan said HubSpot has built one and it is working.

The first thing he expects to change is the top of the funnel: being found in AI assistants instead of Google (Lenny called this AEO), which changes how websites should be built.

"Forward deployed engineers" are sales engineers with a new name

Asked what AI-native companies are doing differently in go-to-market today, Halligan answered bluntly that almost nothing has changed. He expected things to be totally different in AI. Instead, the companies he works with are hiring the same kinds of people and running the same enterprise sales processes. The main difference is that sales engineers or solutions consultants are now called "forward deployed engineers." He spent the first ten years of his career at PTC, which he called an enterprise sales machine, and says enterprise sales hasn't changed much since the 1990s. He grants that these engineers may configure and train the product differently, and he's fine with the term. But in his view, the role looks very similar to what it replaced.

34:23

How the CEO job has changed: speed, focus, and the tax on optionality

The biggest change from 10 or 20 years ago, in Halligan's view, came from something Winston Weinberg told him about a year earlier. He was skeptical at first but now agrees: you can simply do much more. Agents and more productive developers mean something that took a year may now take two months.

He sees danger in this. A company with a deep, promising beachhead market may jump to its second act too quickly and lose focus on the first. He offered an imperfect analogy: OpenAI pursued many things beyond ChatGPT, then, when Gemini came out, refocused on the core.

He also thinks planning cycles have shrunk from a year to about three months. That puts pressure on CEOs to make decisions faster and better. Looking back, he said slowdowns at HubSpot were usually his fault, because hard one-way-door decisions were sitting on his desk, sometimes for as long as a year. Once he made them, everyone moved much faster. He said he always valued optionality, but now thinks there is "a massive tax" on optionality when you can move this fast and try so many things.

Halliganisms: "When you have to eat a sandwich, don't nibble" and "Next play"

Lenny walked through several of Halligan's "Halliganisms," which Halligan describes as a summary of the mistakes he made in 15 years as CEO.

The sandwich line comes from Google CFO Ruth Porat. Halligan applied it to a situation he expects: a retrenchment in valuations within the next couple of years. He described public markets as tight, "the anti-bubble," and private valuations as "a real bubble," and expects a reckoning in which many companies will need layoffs. The temptation is to do a small layoff, hope to grow into it, and then do another six months later. His advice is to rip the band-aid off, tell people the bad news because they are adults who can handle it, and get it done.

He paired this with Duke basketball coach Mike Krzyzewski's sideline call of "next play." A player who misses a shot tends to overcompensate on defense and compound the error with a foul. Krzyzewski wants the player to forget the miss and run the next play. At times, HubSpot put Krzyzewski's face on a slide at company meetings after an unforced error.

His example was the last day of March 2019, when HubSpot had a bad, day-long outage, something it had never really experienced. Customers were unhappy, many canceled, and many yelled at him. He said he cried in front of the whole company at the next company meeting, and used the "next play" slide. He added that most of the bad things that happened to HubSpot were self-inflicted. Companies, he said, are more likely to die of overeating than indigestion, usually from trying to do too much.

42:08

"Never waste a good crisis"

Halligan said most of the good things that happened at HubSpot came out of crises, because the company took drastic measures to fix problems and prevent a repeat. After the 2019 outage, HubSpot rethought how it built and deployed software. He says it hasn't had a serious outage since, and quality is much better.

The crisis also forced a mindset shift. HubSpot started as marketing software and pivoted into CRM after Salesforce entered its market. A bug in marketing workflows is bad but survivable. A CRM outage on the last day of a quarter directly hurts customers' ability to do business. The company hadn't fully absorbed how important it had become to its customers. Halligan said HubSpot "always overcorrected," deliberately swinging the pendulum hard the other way so everyone could see what was changing.

43:52

"If you want to kill a plant, have two people water it"

If you leave for a month and ask two friends to water your plant, Halligan said, it will either be overwatered or not watered at all, and it dies either way. Every CEO at his adults table has learned this and is "religious" about the DRI, the directly responsible individual. Kids-table CEOs talk about DRIs, but it doesn't bite until a company reaches scale.

His explanation: in a small company everyone is in the room. On a pilot with a big account, sales, service, and engineering all know what's going on. At scale, those functions become separate organizations that don't know what the others are doing. Yet everything important at scale happens cross-functionally, so one powerful person must own it, with the authority to tell people in other divisions what to do even though they don't report to that person. Committees, he agreed with Lenny, never work.

46:19

No silver bullets, and no one coming to rescue you

Halligan said he used to believe, wrongly, that one hire, one investor, one event, or one product release would be a silver bullet. From outside, HubSpot's trajectory looked smooth and up and to the right. From inside, it felt like two steps forward and one step back, over and over, often because a crisis caused the step back.

He added that founder CEOs, especially in their 20s, learn during their first crisis that no one will rescue them: not parents, not VCs, not a thesis advisor. You can get help, but it is on you. Even in his coaching role, he said, he can be a shoulder to cry on and offer advice, but the responsibility stays with the founder.

Asked whether he talks people out of starting companies, Halligan said he does, often. He noted that he'd heard Jensen Huang say he wouldn't start Nvidia again. Halligan said that he himself would start HubSpot again, even though it was very hard, involved many sacrifices, and wasn't glamorous. He cited a line he attributes to the Dalai Lama about living a good life so you can live it again on your deathbed.

On work intensity, he said the founders he works with go well beyond "996." They work seven days a week, are always on, and text him on Sunday nights. He attributes this to founders seeing a massive platform shift and not wanting to waste the opportunity, and he thinks that mindset is right. By his account, he worked 60 to 70 hours a week and never really turned off, but today's founders are "much more hardcore," which he suspects Elon Musk has inspired. He said he doesn't recommend it and didn't have work-life balance himself. The one exception he knows is Kareem Amin of Clay, who tells people to take weekends; Halligan plans to interview him about that. Lenny joked that Clay took a long time to find product-market fit, though it worked out.

EV > TV > ME, and how HubSpot enforced it

This formula stands for enterprise value over team value over "me" value. As HubSpot scaled, Halligan said, VPs with sizable organizations often failed by optimizing for their own teams rather than the company. A sales leader paid on bookings might maximize bookings and leave service to deal with the downstream problems. Similar conflicts arose between marketing and sales and between other departments. Employees noticed and complained.

It showed up in HubSpot's quarterly employee net promoter survey, broken down by department. If sales had been running at 65, 62, 68 and suddenly dropped to 30, the comments were usually about the leader, often about this kind of team-first behavior. HubSpot shared the feedback with the VP and tried to help. But Halligan said the score would typically fall further, to around −5, the next quarter, and leaders almost never recovered. Once you lose your team, he said, it's hard to get them back, which is another reason to fire fast. He said this doesn't appear in the first 100 to 150 employees but emerges once layers form between the CEO and staff. HubSpot later added CV, customer value, at the front: customers first, then HubSpot, then the team, then yourself.

Halligan also quoted Steve Jobs's line that you don't work for your boss, you work for Apple. On making the principle concrete, he described several practices. The principle was an explicit scored item in performance reviews. He repeated it constantly. Early on, he ran HubSpot somewhat like Jensen Huang runs Nvidia, without one-on-ones, giving good and bad feedback publicly in large management meetings and going out of his way to criticize people who put their team over the company. At each well-produced quarterly company meeting, the co-founders handed out "champagne awards," signed bottles of Veuve with a note read aloud, and usually one recognized enterprise-first behavior.

55:25

Employee-centric vs. customer-centric

Halligan believes every company has one center of gravity: customers, employees, or investors. For its first several years, HubSpot was more employee-centric than customer-centric. It was ranked the number-one place to work on Glassdoor, and he was the top-rated CEO there. Looking back, he's not sure that was good. He no longer thinks wanting to be liked is a good trait in a CEO, and he pointed to Tobi Lütke of Shopify, whose ratings aren't great while the company does very well. HubSpot over-indexed partly because his co-founder was strongly focused on it and because it had a powerful head of HR, Katie Burke. In a four-hour management meeting, about two hours would go to employee topics.

Eventually he asked why they spent so much time on employee NPS. If employee NPS was 60 and customer NPS was 25, he said he would trade ten points of the former for ten of the latter. Several changes moved the center of gravity. HubSpot's management team met monthly, and each meeting included a customer panel where Halligan asked pointed questions to surface bad news. Board meetings also got customer panels, where his favorite questions are what customers love and what they hate about HubSpot. Customers appeared at company meetings. Management compensation shifted from revenue to retention and customer NPS.

Lenny noticed a pattern: changing culture seems to require overcorrecting. Halligan agreed and added two observations about the CEO role at scale. First, you have to say the same thing "over and over and over" before it sinks in. Second, people put you on a pedestal you don't deserve. A casual hallway remark along the lines of "it'd be cool if we had a product that did X" could send someone home to build it as "a big initiative Brian wants." So CEOs must be repetitive and careful about what they say. HubSpot responded with a tagging system, which Lenny said co-founder Dharmesh Shah had described, to label each message by intent: something that must get done, something to discuss, or just an FYI.

Halligan also told the story of Dharmesh's condition for co-founding HubSpot. Dharmesh had been a CEO before, considered himself bad at it, wanted Halligan to be CEO, and said he would never have direct reports. Halligan assumed he was joking. When HubSpot reached 10 or 12 people and needed someone to manage engineers, Dharmesh reminded him of the promise. Halligan, who is an engineer but says his own coding isn't good, ended up managing them. According to Halligan, Dharmesh has never had a single direct report at HubSpot, which freed him to think and be creative.

From perspiration to inspiration, and the limits of trust

On how the CEO's time shifts with scale, Halligan used his own rubric. The startup phase is 90% perspiration and 10% inspiration, and the scale-up phase is the reverse. In a startup you do every job, and even later you must stay close to the work and keep talking to customers. But you also have to let go of a great deal for the organization to scale.

He was candid that this was his own limit. He said he has trust issues and trusted only a small number of people at HubSpot to be DRIs for important work, which drove people crazy. Every CEO he works with has the same problem, and he considers it a scaling limit.

The Grateful Dead as a Silicon Valley startup

Halligan's podcast title references the Grateful Dead, and he wrote a book, Marketing Lessons from the Grateful Dead. He calls the band the ultimate Silicon Valley startup. They started in 1964 in Palo Alto, played early shows around Stanford and the Valley, thought from first principles, created a new category, found new ways to distribute their music, and disintermediated ticketing companies. He sees Jerry Garcia and Steve Jobs as similar craftspeople. He bought one of Garcia's guitars and describes himself as its steward. Dead & Company and many cover bands have played it.

His main lesson from the band is about spiky teams. Garcia was a bluegrass banjo player. Bob Weir, who Halligan noted recently passed, came from country music. Bassist Phil Lesh was an avant-garde jazz trombonist, keyboardist Ron "Pigpen" McKernan was a harmonica player, and the drummer came from marching band. Together they created a new genre, the jam band: rock and roll played in a bluesy, open, jazzy way. For Halligan, spiky teams are underrated in creating categories.

Lightning round: no books, Ken Burns, Delphi, and a snowmobile accident

Halligan said he can't remember the last book he read. He gets information from podcasts, X, and other CEOs. His recent favorite viewing was Ken Burns's long documentary on the American Revolution, "probably 10 plus hours." He admires Burns's craft and sees America as a disruptive startup. The war, as he described it, was "two steps forward, ten steps back," the country came very close to losing most of the time, and it depended on alliances like the one with France.

His favorite product is his Delphi clone, which handles office hours for his course, Scaling Entrepreneurial Ventures. He especially likes the voice feature, looks forward to video returning, and values being able to upload documents that aren't on the internet, such as his lectures, plus a feature where it interviews him. His lowest-rated product is his Sonos system. Lenny agreed it is good in many ways and annoying in many others, and both admitted they still use it.

His life motto came from a snowmobile accident about four years earlier in Vermont. He drove off a cliff and lay unconscious at the bottom for a long time. When he woke, he initially thought he didn't have his phone and expected to freeze to death overnight. After a couple of hours he realized he did have it and called 911. A helicopter took him to the hospital. He had many surgeries, was out of commission for about a year, and now has 33 screws in him. At the bottom of that cliff, he decided he didn't enjoy being CEO of an 8,000-person company and would step down if he survived. He handed the job to Yamini Rangan, who he says is still CEO and doing a great job. His motto is simply that life is short. He thinks people act as if they'll live forever. At 58, he says he is much more intentional about his decisions and the people he spends time with, and tries to work on things that bring him joy.

On the Red Sox, he said owning a baseball team is less profitable than people assume because of how the league's economics are structured. He considers baseball flawed without a salary cap, contrasting the Dodgers' roughly $400 million payroll with the Marlins' roughly $100 million. He thinks the model is broken and predicts it will be corrected in the next couple of years.

He closed with a request. Long Strange Trip started only a couple of months ago, and most of his feedback so far comes from family and Sequoia colleagues. He asked listeners to tell him honestly what they think of it.
