Product-Market FitConsulting

Stop guessing. Start validating. Find product-market fit before you run out of runway.

The PMF Problem

Most startups don't fail because the product is bad. They fail because they build something nobody asked for.

I see it constantly: founders spend months perfecting features while avoiding the uncomfortable work of talking to customers and testing assumptions. They mistake activity for progress. They confuse interest with demand.

I help founders separate signal from noise. Instead of building in a vacuum and hoping the market shows up, I work with you to design experiments that tell you the truth fast, run real customer conversations that surface what people actually need, and make decisions based on evidence instead of intuition. The goal isn't a perfect product. It's a product that someone will pay for, use again, and tell their friends about.

What I Help You Do

Validate assumptions before building — so you don't waste months on something nobody wants

Design experiments that produce real signal — not vanity metrics that make you feel good

Talk to customers (not just survey them) — because the best insights come from real conversations

Identify your wedge market — the smallest group of people who desperately need what you're building

Build your first repeatable sales motion — so growth isn't accidental

Know when you've found it vs when you're fooling yourself — because false PMF is more dangerous than no PMF

Where You Are

PMF work looks different depending on your stage. Here's where I typically engage:

MVP

You've built something but aren't sure if anyone needs it yet.

First Customer

You have early users but can't tell if this is real traction or just momentum.

Some Traction

Revenue is coming in but you're not sure it's repeatable or scalable.

Who This Helps

Technical Founders

You can build anything but need help figuring out what's worth building.

Academic Founders

You have deep domain expertise but need to translate research into market demand.

Bootstrapped Builders

Every dollar counts, so you need to find PMF fast without burning through savings.
