From messy product idea, unclear AI feature, half built MVP, clunky onboarding, low activation flow, feature nobody gets, investor demo conceptto dev-ready prototype in 2 weeks
I'm Peter Marc. I help technical founders turn rough ideas, unclear AI features, and half-built MVPs into product flows your team can test, pitch, and ship.
Startups don't need more design theatre. They need product clarity
Most early products aren't held back by missing pixels. They're held back by unclear thinking that everyone can feel but no one has time to fix. Baymard's UX research consistently shows the same pattern in mature products: users drop when the first useful action is buried.
Your MVP is hard to explain
The idea is strong, but it takes three paragraphs and a diagram before anyone gets it. Progressive disclosure helps, but only after the core job is obvious.
Your demo needs too much narration
The product can't carry the story on its own, so every pitch leans on a founder talking over it.
Engineering is moving faster than design
Devs are shipping while the product direction is still being figured out in real time.
AI features feel powerful but unclear
There's real capability under the hood, but the experience doesn't make it obvious or trustworthy. Teams shipping AI surfaces face the same trust gap Anthropic describes in product design.
The product looks less mature than the company
The team and ambition are serious. The interface quietly undersells both.
You need senior judgment, not a full-time hire
You want someone who's seen this before, without committing to a headcount you can't justify yet.
Founder speed. Senior design judgment
I'm not an agency and not a generic freelancer. I'm one lead product designer who can sit in the messy middle with you, from a rough idea, not only a polished brief.
I've shipped products where unclear UX costs real money: fintech onboarding, mobile commerce, platform merges. Checkout and onboarding research shows how fast intent erodes when the first step asks for too much. I use AI tools to compress product cycles, not to replace thinking.
This isn't a typical client-service relationship. I share feedback honestly, align with founders and product teams, and care about outcomes as much as the work itself.
I can move from strategy to prototype to handoff without dropping the thread. I know when you need a system and when you just need to ship.
Fifteen years of shipping real product
I've worked on products where unclear UX costs real money and trust: fintech, mobile, logistics, and complex B2B, across startups, scaleups, and enterprise teams.
Start small, then scale if the work is useful
Most projects start with a focused diagnosis. This keeps the first step clear and useful before committing to a larger project.
Who this is for
Technical founders and product teams with something real in market, an MVP, early users, or a live product that still needs too much explanation.
- B2B SaaS, AI tools, fintech, or devtools
- Onboarding, demo, or activation feels harder than it should
- You want a diagnosis before committing to a full redesign
- Senior product judgment without a full-time hire
