FOR FOUNDERS AND TEAMS BUILDING SOFTWARE PRODUCTS

Find product‑market fitwithout guessing.

Already building a software product? Good. I work alongside you and your team to de‑risk it with real customers, and coach everyone so you can keep finding product‑market fit on your own.

Every guess costs you time, money and energy you don’t get back.

Advisors give opinions. Dev shops keep the keys. I put your real customers in the room while the product is still cheap to change.

For Founders

Turn doubt into a validated, shipped increment.

For founders building a first product, stuck between directions or midway through a stalled build. I find the customers who will commit to shaping it, test with them throughout, and build what the evidence supports.

For Product Teams

Move from AI experiments to a faster way of shipping.

For product and innovation teams whose roadmaps are tied to outputs and whose AI tools have not changed the work. I work on your real backlog with real customers as design partners, rebuild how the team works around AI-native research and prototyping, and coach every product manager until it holds.

More about Marc

“There are plenty of tools that help you build faster; far fewer help you build the right thing.”

Greg Kostello, CTO, Cogzia

“Before, I had a myriad of ideas and possibilities jumbled among operational and administrative needs, stalling our go-to-market. Now I’m equipped with strategies and tools to accelerate our launch with certainty.”

Diana Schuetz, Safe Players

Everything starts with a design partner.

A design partner is a person or team who wants what you are making enough to help you make it. They give you their time and honest reactions. You give them a product shaped around their problem, before it is finished. Whether you are a founder looking for your first few or a product team choosing where to begin, it is the fastest way I know to turn a guess into evidence.
