In this episode of Lenny's Podcast, featuring Todd Jackson and Lenny Rachitsky, A framework for finding product-market fit | Todd Jackson (First Round Capital) explores four-Level Roadmap To Product-Market Fit For B2B Founders Todd Jackson, partner at First Round Capital and longtime product leader, shares a structured, data-informed framework for B2B, sales-led startups to understand and systematically achieve product-market fit (PMF).

Four-Level Roadmap To Product-Market Fit For B2B Founders

Todd Jackson, partner at First Round Capital and longtime product leader, shares a structured, data-informed framework for B2B, sales-led startups to understand and systematically achieve product-market fit (PMF).

He breaks PMF into four levels—nascent, developing, strong, and extreme—across three dimensions: satisfaction, demand, and efficiency, explaining what each level feels like, typical metrics, and how long they tend to take.

A key tool is the “four Ps” (persona, problem, promise, product) that founders can actively adjust when they’re stuck, illustrated through case studies like Vanta, Lattice, Looker, Ironclad, Plaid, and others.

Todd also previews First Round’s free Product/Market Fit Method program, which gives early B2B founders a structured, hands-on process (including dollar-driven customer discovery and founder-led sales) to materially increase their odds of reaching strong and extreme PMF.

Key Takeaways

Treat product-market fit as a multi-level journey, not a binary event.

Todd defines four levels of PMF (L1–L4) that typically unfold over 4–6 years, with each level emphasizing different dimensions—starting with satisfaction, then demand, then efficiency—rather than expecting a sudden 'geyser' moment.

At Level 1, optimize only for deep satisfaction with a tiny set of customers.

Your job is to find 3–5 paying customers with an urgent, important problem and deliver a highly satisfying solution—often manually or inefficiently—before worrying about scale, channels, or margins, as Vanta did with early SOC 2 work.

Use the four Ps to decide how to pivot when stuck.

If growth stalls, systematically revisit persona, problem, promise (positioning), and product; for example, Lattice kept its persona (heads of HR) but changed the problem, promise, and product from OKRs to performance management, while Plaid kept product code but changed the other three Ps.

Level 2 is about unlocking repeatable demand, not just grinding more sales.

Once you have ~5 satisfied customers, the focus shifts to getting to ~25 through emerging scalable channels (cold outbound, content, partnerships, events), while watching for yellow flags like high regretted churn, slow cycles with low ACV, and flatlining inbound interest.

Strong and extreme PMF depend on efficiency as much as growth.

At Levels 3 and 4, you’re aiming for 25–100+ customers and $5M–$25M+ ARR with improving efficiency metrics (burn multiple, gross margin, payback, NRR) so that each marginal customer is easier and cheaper to win and serve, rather than “$1 in, $2 out” WeWork-style economics.

Do 'dollar-driven' discovery to validate willingness and ability to pay.

Move beyond polite feedback by probing extreme value, budget sources, competing spend, decision paths, and price bands (fair/expensive/prohibitively expensive), and by looking for concrete behaviors (e. ...

Most startups stall at Levels 1–2; knowing the map raises your odds.

Todd estimates roughly 60% of startups never make it past Level 2; having clear definitions, benchmarks, and tactical levers (four Ps, discovery scripts, founder-led sales discipline) can nudge more companies into strong/exreme PMF and help others decide earlier when to pivot or wind down.

Notable Quotes

Finding product-market fit is the single most important thing that your startup does in the first three years.

Todd Jackson

Product-market fit is not a one-size-fits-all thing and it doesn't just happen overnight.

Todd Jackson

Most founders do like a 10% pivot, and what they need to be doing is a 200% pivot.

Todd Jackson (quoting Jack Altman)

We can't guarantee success here. What we are trying to do is increase your odds and reduce the role of luck.

Todd Jackson

Every customer we got, whether that was number four or number 14, felt like the last customer we were ever going to find.

Todd Jackson

(instrumental music plays) Finding product market fit is the single most important thing that your startup does in the first three years. And it's just under-explored and it's just under-explained as a topic.

Lenny Rachitsky

You've been working on a product market fit framework.

Todd Jackson

We've published dozens of articles on the First Round review, and we have found a very consistent set of patterns: demand, satisfaction and efficiency. But the interesting thing is that you don't go for all three of them from the very beginning.

Lenny Rachitsky

There's essentially four levels of product market fit: nascent, developing, strong, extreme.

Todd Jackson

Roughly 60% are never gonna get past L2.

Lenny Rachitsky

These four Ps is essentially what you should try to change if you're stuck.

Todd Jackson

You've got the persona, the problem, the promise, and the product. Lattice kept the first one but changed the others. Vanta changed all four.

Lenny Rachitsky

Hearing level three tells me level two is basically your pivot from, "I'm just grinding, selling, pitching."

Todd Jackson

This is where it starts to get fun.

(instrumental music plays) Today, my guest is Todd Jackson. Todd is a partner at the legendary VC firm First Round Capital. I rarely have VCs on this podcast, but as Todd shares at the top of this episode, Todd is a very special VC. Prior to moving into venture, he was product lead for Gmail for four years. He was product manager of Facebook's news feed, photos and groups, including leading a major redesign of the news feed. He's also director of product management at Twitter and VP of product and design at Dropbox. He's also a founder, and sold his company to Twitter. This episode is a very different and special kind of episode. Todd and the team at First Round have spent the last year looking at all of their data and the journeys of the hundreds of startups that they've worked with over the years, and through that, have put together a very practical and very actionable framework to help founders find product market fit. They're turning this framework into a three-month program for founders. And in this conversation, Todd shares an exclusive peek into the program, in particular the stages of product market fit. We talk about how to know which stage you're in, what to do if you're stuck in that stage, and also what you can change in order to get unstuck. If you're a founder or building a new product within a company and feeling like you're not making as much progress as you'd hope, you will find tremendous value in this conversation. With that, I bring you Todd Jackson, after a short word from our sponsors. And if you enjoy this podcast, don't forget to subscribe and follow it in your favorite podcasting app or YouTube.
