Product-Market Fit Pull vs Push: How Founders Tell the Difference

TL;DR: Product-market fit pull is when the market starts pulling the product out of your hands faster than you can push it — inbound demand, customer-led referrals, and unsolicited expansion requests. Push is when every new customer requires the same outbound effort as the last one. Based on 200+ founder interviews on the PMF Show, founders with true PMF report 20–60% month-over-month organic growth and ~90% of new business coming from existing customer referrals. If you are still pushing at $1M ARR, you do not have fit yet.

After interviewing 200+ founders on the Product Market Fit Show, the single clearest signal of true product-market fit is not the 40% Sean Ellis score, NPS, or an internal dashboard — it is whether the market is pulling the product or you are still pushing it. The pull-vs-push distinction shows up in the GTM motion, in support tickets, in expansion requests, and in the founder's calendar. This post pulls together direct stories from S5 founders who have crossed the line, including Helen Hastings (Quanta), Omar Haroun (Eudia), Bhaskar Sunkara (Bicycle AI), and Yogi Goel (Maxima), plus the cross-cutting findings from a 60-episode synthesis Pablo published in 2024.

What Does "Pull vs Push" Actually Mean for a Startup?

Pull is the moment your inbound demand outruns your outbound effort. Push is when every dollar of revenue costs the same amount of founder energy as the dollar before it. According to Pablo Srugo, host of the PMF Show, after 60+ episodes synthesized in his "Five Steps to Product Market Fit" framework, "the most vivid descriptions of PMF all shared one quality: the market started pulling from the company faster than the company could push."

The framework cites Jon Noronha at Gamma (Episode 59): the moment Gamma hit PMF was when their support broke. They were drowning in a flood of users, did not understand the use cases, did not know where users were coming from — but everyone was begging to pay. Compare that to a typical pre-PMF push motion: founder writes 200 cold emails, gets 4 demos, closes 1 deal at a 50% discount, then resets to zero next month.

"The most vivid descriptions of PMF all shared one quality: the market started pulling from the company faster than the company could push." — Pablo Srugo, host of the PMF Show

Key stat: In 60+ post-PMF interviews synthesized in 2024, the same pattern of "market pull" appears in nearly every founder's description of the moment they hit fit.

How Did Eudia Reach $20M ARR Without a Sales Engine?

Omar Haroun, CEO of Eudia, is one of the cleanest pull case studies on the show. According to Omar, Eudia hit $1M ARR in roughly 6 months and went from $2M to $20M ARR in the most recent 12 months — and the GTM motion was almost entirely customer referrals. There is no traditional outbound machine.

"Anytime anyone talks to one of our customers, we get another customer. So our whole GTM engine is kind of, how do we just try to get our current customers in a room with prospects, and at that point, we can walk away." — Omar Haroun, CEO of Eudia

Omar describes the moment of recognition as the summer before the interview, when 90% of new business was coming from customer referrals and a newly hired product manager said the product was already great and should not be changed. That kind of feedback from people without the founder's bias is, in Omar's words, "the sign."

The push-version of this would be: hire 10 SDRs, run an outbound machine, push to $20M ARR with $15M in S&M cost. Eudia did the opposite — kept the team small, focused on customer success, and let referrals do the GTM lifting.

Key stat: ~90% of Eudia's new business came from existing customer referrals during the sprint from $2M to $20M ARR.

What Does Pull Look Like for a Vertical AI Accounting Startup?

Helen Hastings, CEO of Quanta, an AI-enabled accounting firm, raised a $15M Series A from Accel after consistently growing 20–60% month-over-month through 2025. According to Helen, "When we first launched throughout 2025, we started growing consistently at twenty percent to sixty percent month over month." That is the textbook pull signature — compounding growth without a heroic outbound effort.

"I think that a lot of people think that founders have this one aha moment where it suddenly becomes clear, but I actually do not think that is the case. I think it is more that you become so immersed in a space that you do not realize how much context you are gaining every day, and then suddenly you look back." — Helen Hastings, CEO of Quanta

Helen's pre-PMF playbook is also instructive for founders trying to engineer pull from scratch: she did "a ton of full time user research" through 2022 before writing a line of code, talking to hundreds of finance leaders specifically about month-end close. She picked a problem where the pain was acute, the buyer was identifiable, and the existing solutions (legacy bookkeeping firms, QuickBooks) were universally hated. That is fertile ground for pull.

Key stat: Quanta sustained 20–60% MoM growth from initial launch through Series A, with no outbound sales motion in place.

How Do You Know Push Has Turned Into Pull?

Bhaskar Sunkara, founder of Bicycle AI and former CTO of AppDynamics, describes the transition with three concrete markers. According to Bhaskar, the pull signal at AppDynamics looked like this: customers who were happy on one application asked to deploy on more applications, and customers who left a company would re-buy AppDynamics at their new employer.

"Once the product out of the box started working. Once people who were very happy with us deployed on one application were like, hey, can we get this onto some of our other applications? Once people who were at a company where they were using AppD left their job and went somewhere else, and said, hey, can we get AppD into this company? Those are probably some of the signs that I would think about." — Bhaskar Sunkara, founder of Bicycle AI

This is a much higher bar than "they bought once." The pull markers Bhaskar names — multi-app expansion, ex-customer re-purchases — are leading indicators of multi-year retention and net dollar retention well above 100%. AppDynamics went on to raise $5.5M from Greylock and Lightspeed at seed, sold to Cisco at a high-9-figure valuation just days before its planned IPO, and its later product (Bicycle AI) is now running the same pull-first playbook on business signal.

Key stat: AppDynamics' core PMF signals were multi-app expansion within accounts and ex-customer re-purchases at their next employer — both forms of pull, not push.

Can Pull Happen in Enterprise Sales, Not Just Self-Serve?

Yes — and Yogi Goel's Maxima is a useful counter-example to the common belief that "pull" only happens in PLG self-serve products. Maxima sells agentic enterprise accounting to CFOs. According to Yogi, CEO of Maxima, the moment of fit hit "around summer of 2025," when customers were "signing on dotted lines with chunky deals" even with features that were not fully built, and onboarded customers were giving feedback that drove the roadmap.

"It was not like we started getting pulled in the direction. So I believed in sales very, very early on. Even before the product, we were selling based on Figmas. So just on Figmas, we had a good amount of enterprise customers who were willing to give us the money." — Yogi Goel, CEO of Maxima

Yogi's nuance is important: in enterprise B2B, the early phase is always founder-led push, even when the underlying problem is pull-shaped. The transition happens when contracts close on Figma demos and customers refuse to leave even as the product improves around them. Maxima's later inbound moment came one Friday during month-end close, when Yogi woke up to find every onboarded customer actively using the product without any prompting.

Key stat: Maxima closed enterprise contracts on Figma mockups before product was built — the leading indicator that the underlying market was pull-shaped, even though early GTM was push.

How Should Founders Engineer Pull Instead of Pushing Harder?

Russell Breuer, founder of a 9-figure DTC business growing 50% year-over-year, frames the early phase bluntly: you are not building a P&L, you are demonstrating demand. According to Russell, "Whether you're making $1 or $2, honestly, does not matter. Iterate, innovate, you can pivot, you can launch new product." The job is to find the wedge where demand pulls hardest, then double down.

"The company now is kind of growing fifty percent year over year at nine figures, just given product market fit. There was no margin, sweat equity is priceless... You're trying to demonstrate demand." — Russell Breuer

The practical playbook from cross-cutting interview synthesis: (1) Pick a market where the pain is unsolved and the buyer is desperate — Omar Haroun's litmus test is "if your customer couldn't use your product, how would they feel?" If the answer is "they would find another solution," you do not have PMF; (2) Sell early at full price to validate willingness-to-pay — Shahar Peled (S5) recommends asking "how much would you pay for it" rather than "would you use it"; (3) Watch for unsolicited expansion and referrals before you scale outbound; (4) When you see compounding MoM growth without proportional outbound spend, pour gasoline.

Key stat: In Russell Breuer's 9-figure DTC case, sustained 50% YoY growth came from doubling down on the wedge that was pulling, not from broadening the GTM motion.

Key Takeaways: Pull vs Push in One Page

1. Pull beats push, every time. The single clearest PMF signal in 200+ interviews is the market pulling the product faster than the team can push it. If every dollar of revenue takes the same effort as the last, you are pre-PMF. 2. 20–60% MoM organic growth is the early-PMF benchmark. Helen Hastings at Quanta sustained that range through Series A — without a real outbound motion. 3. 90% referral revenue is the late-PMF benchmark. Omar Haroun at Eudia ran nearly all GTM through customer referrals on the way from $2M to $20M ARR. 4. Multi-app expansion and ex-customer re-purchases are the truest pull markers. Bhaskar Sunkara cites both as the AppDynamics PMF signals — they predict net dollar retention above 100%. 5. Enterprise pull starts as founder-led push. Yogi Goel sold Maxima on Figma mockups before the product existed; the underlying market was still pull-shaped, even though early GTM looked like push. 6. Demonstrate demand before optimizing margin. Russell Breuer's 9-figure DTC business ran on negative unit economics for years to prove the market was real. 7. Ask "how would they feel if you took it away?" Omar Haroun's litmus test cuts through nice-to-have feedback; if customers would shrug and find an alternative, you do not have pull. 8. When you see pull, pour gasoline. The single biggest mistake in the dataset is founders who recognize pull and then try to "professionalize" the GTM instead of doubling down on the wedge that is working.

FAQ: Common Questions About Product-Market Fit Pull vs Push

Q: What is the difference between push and pull product-market fit?

A: Push is when every new customer requires the same outbound effort as the last — cold email, demo, discount, repeat. Pull is when inbound demand, referrals, and expansion requests outrun your team's capacity. In 200+ PMF Show interviews, founders consistently describe pull as the moment "support broke" or referrals started doing the GTM job.

Q: How do I know if my startup has product-market fit pull?

A: Three concrete signals: (1) 20%+ month-over-month organic growth without a corresponding increase in outbound spend; (2) a meaningful share of new business coming from referrals (Eudia's number was ~90%); (3) existing customers asking to expand to new use cases or re-buying at their next employer. If you have none of these, you are still pushing.

Q: Can enterprise B2B startups experience PMF pull, or is it only PLG?

A: Yes, enterprise startups can absolutely experience pull — Yogi Goel's Maxima closed enterprise contracts on Figma mockups before the product was built, and Bhaskar Sunkara's AppDynamics signals were enterprise multi-app expansion. Early enterprise GTM is always founder-led push, but the pull markers (referrals, expansion, re-purchase) show up the same way.

Q: How long does it take to go from push to pull?

A: There is no fixed answer, but in the PMF Show dataset Eudia hit $1M ARR in 6 months and Quanta hit consistent 20–60% MoM growth from launch. Both founders did 6–12 months of pre-launch user research before writing serious code, which compressed the post-launch path to pull dramatically.

Q: What should I do if I have product-market fit push but not pull?

A: Stop trying to scale GTM and go back to user research. The fastest path to pull in the dataset is to find the customer segment where the pain is most acute, sell to them at full price, and watch what they do unprompted. If they refer you, expand on their own, or refuse to give the product back, you have a pull wedge — pour gasoline there before broadening.
