Founder Topic

How do early-stage founders find their first customers?

What actually works: direct, unscripted conversations with people who have the problem. Embedded time inside the customer's world. Listening for the workarounds they've already built. Stopping when you can describe the pain in their language better than they can.

Customer discovery is the unsexy work most founders skip — and the single biggest predictor of which early-stage companies survive. It's the process of confirming whether a problem is real, urgent, and worth building for, before writing a line of code. Across the Founders In Motion archive, the founders who closed customers fast had one thing in common: they did discovery as a contact sport, not a survey.

Quick answers

How many discovery conversations is enough?

No magic number, but the FiM archive suggests at least 50 before you build, and 200+ before you sell at scale. Shakeel Lala ran 800 conversations across nine months before Marloo had product-market fit. Satya Tumati at Socratix AI spent months embedded in risk teams. The metric that matters: can you describe the customer's problem in their words better than they can?

What's the right way to structure a customer discovery call?

Open-ended, customer-led. Ask about their last week (not their hypothetical future). Record everything. Look for the language they actually use. Avoid pitching your solution until you can describe the problem better than they can. The mistake most founders make: turning discovery into a sales call before they've learned anything.

When do you stop doing customer discovery?

When the same answers keep coming back. When you can predict what the next 5 conversations will say. When you have evidence that customers are already paying real money for workarounds. Hamish McKay learned this directly with Order Editing — discovery told him Nike was using a manual workaround for the exact problem he was building for. That was the green light.

Shakeel Lala · Marloo

$40M FinTech Founder on Raising Millions Before He Had a Business Idea

Shakeel quit his job, convinced one of Australia's largest VCs to back him with no business idea, ran 800 conversations with financial advisors over 9 months, then vibe-coded a demo the week before Australia's biggest financial advice conference. People tried to buy it on the spot. Marloo has since raised $10M and is live across 6 countries.

650+Financial advice firms now using Marloo across six countries, including the US, Canada, UK and Australia.

"You can vibe code your ideas. You can vibe code products. But you can't vibe code customers. And you can't vibe code sales. Distribution matters more than anything."— Shakeel Lala, on the limits of AI in early-stage building (15:30)

Satya Tumati · Socratix AI

Why This YC Startup Just Raised $4M to Catch Fraud Before It Happen

Satya Tumati used to connect his laptop to a self-driving car and push code that moved a two-ton robot in real time. Now he's raised over $4 million to build AI co-workers for fraud and risk teams — and his first customer came from a completely cold message.

$4 millionRaised to reinvent the way the world fights financial crimes

"so here I am writing some code and seeing a two-ton robot respond to it in real time. It was pretty surreal. The physical world is your integration test. It was equal parts terrifying and a little bit addictive too."—

Nam Nguyen · TruthSystems (YC S25)

How He Turned 3 YC Rejections into a $25M AI Governance Company

Nam's co-founder was 19 years old. Law firms told them "come back in 5 years." They applied to YC four times. When they finally got in, their $4M round filled in 48 hours. TruthSystems is now the AI governance layer sitting inside law firms in real time.

$4MSeed round filled in approximately 48 hours after YC acceptance — Sunday night to Tuesday night.

"We had firms tell us, "come back in five years. Come back when you are Microsoft-sized." When you're that young you actually don't get a lot of benefit from the imagination. We realised we had to remove imagination from the equation — less vision, but actually more of the product."— Nam Nguyen, on selling AI governance as a 21-year-old (05:23)

Celeste Amadon · Known

This Stanford Dropout Wants to Help You Fall in Love

Celeste was 21 when she walked into Forerunner Ventures. She raised her pre-seed in 8 days, her seed in 4 days, and fielded 12+ term sheets. Known has set up 1,500 curated dates in beta and hundreds of couples are now in relationships. Her thesis: today's apps are perversely incentivised to keep you single and paying.

8 / 4 daysPre-seed closed in 8 days. Seed closed in 4. More than a dozen term sheets across the two rounds.

"Today's dating apps have been designed and tweaked and redesigned and redeployed to keep you single. They're perversely incentivised to try and keep people on the apps for longer — keep people hopeful enough but also unsatisfied, so that they're more likely to upgrade to being paying users."— Celeste Amadon, on the structural problem with the category (00:00)

Selina Li · gymii.ai

She Built an AI App Alone in 60 Days

Selina Li built the MVP of gymii.ai in two months with no prior full stack experience, then chose to bootstrap rather than chase VCs while building a nutrition-tracking app that's social on purpose.
