Founders who shipped — and stuck around.
A few words from the founders, CTOs and operators we've built with. Most of them are still customers — that's the metric we care about most.
The handoff documentation alone saved us a hire. They didn't just ship a product — they shipped a team's worth of judgment along with it. Two years later, our in-house engineers still reference the architecture RFCs they wrote on day one.

“We came in with a half-broken Lovable app and 8 weeks of runway. Fusionwave rebuilt it on a real stack, shipped the App Store version, and we closed our seed round on the demo.”
“The AI automation alone cut 14 hours/week of manual lead routing. ROI in 3 weeks. Their human-in-the-loop design meant we never had to roll anything back.”
“They treated our product like their own. Code reviews, performance budgets, accessibility — things our last agency never even mentioned. We didn't realize how low the bar had been.”
“We've worked with three agencies before this. None of them shipped on time. Fusionwave did, every sprint. The Friday demos became something the team actually looked forward to.”
“From Figma to TestFlight in 9 weeks. The clickable prototype they handed to our investors closed the round before we'd shipped a single line of code.”
“HIPAA compliance had been a perpetual sticking point for us. They turned it into a checklist tied to our PR template. The audit log we got is now the gold standard we benchmark our other vendors against.”
“Our retention went from 22% at 12 weeks to 60%. The motivation loops they designed weren't loud — they were specific. That's the part we never could have built without a senior product team.”
“They told us where AI was the wrong answer — twice. That kind of honesty saved us 4 months of building something users wouldn't have trusted.”
“Four product surfaces — web, mobile, admin, super-admin — built in parallel and shipped on schedule. I still don't fully understand how they pulled that off.”
“The daily check-in compliance rate alone made the engagement worth it. 71% sustained at 90 days is unheard of in our category.”
“We had three Replit prototypes that kept breaking under real traffic. They audited, rebuilt and migrated us in 6 weeks — and our customers never noticed the switch.”
“The vendor side of our marketplace was always the weak link. Fusionwave designed a dashboard our vendors actually open daily. We're not used to that.”
