After 10 years and 52 projects with startups from MVP to Series A, I keep seeing the same pattern: Founders treat design like a checkbox.

They raise a seed round on a scrappy MVP and a solid pitch. 6 months later, you're talking to enterprise customers, running ads, pitching Series A investors. Your GTM evolved. Your team grew. But your product didn't.

Now you're stuck:
→ Users churn in onboarding because the flow is confusing.
→ Enterprise buyers bounce after 10 seconds because your product looks unpolished.
→ Investors compare your deck to 50 others and pass with "not ready yet."
→ Your site converts at 2% when it should convert at 8%.

Design isn't just holding you back - it's costing you deals.

Most founders realize this too late.
→ They hire mid-fundraise (takes 3+ months to find someone good).
→ Or they work with agencies that take 6 months and $100K.
→ Or they patch together freelancers who execute but can't think strategically.

The pattern I've seen work: Treat design like a growth lever, not a nice-to-have.

I'm an embedded design partner who:
→ Ships in weeks, not months 
→ Thinks about conversion and fundraising outcomes, not just aesthetics
→ Gives you senior execution without agency overhead
→ Works with no long-term contracts (pause or cancel anytime)

I work with founders who need their product to match where they're going, not where they've been.

My clients have collectively:
→ Raised $100M+ in funding
→ Scaled to serve 687K+ daily users
→ Won 300+ enterprise clients
→ Achieved successful exits

Recent outcomes:
✅ Coursedog: Contributed to growth from 5 to 300+ US universities, 2.5M students, and $90M raised
✅ Docplanner: Redesigned flow processing 687K+ daily bookings across 13 countries (still live after years)
✅ Brand24: Built design that helped scale to category leader (acquired by Semrush)
✅ Maiden Labs: Concept to 4.8★ App Store rating and 5K+ downloads in 6 weeks
