The AI builder wave changed who can ship. Lovable, v0, Bolt, Cursor — a solo founder can go from idea to live product in days. But speed created a new blind spot.
These products reach real users without ever being tested against the actual humans they're meant for. Traditional user testing assumes you have weeks, a budget, and a research team. Early-stage founders have none of those.
So most just guess. And find out they were wrong after launch.
The question no tool was answering: Does this design actually work for my specific industry and audience — before I spend money acquiring users?

Insight
The problem isn't just slow feedback. It's that feedback was never industry-aware.
A checkout flow for a B2C fashion app needs to feel different than one for a B2B SaaS tool. A 22-year-old mobile-first shopper has completely different expectations than a 45-year-old first-time user. Generic usability testing misses this — it tells you what's broken but not why it's wrong for your market.
That gap is where PersonaLab lives.
PersonaLab generates AI personas calibrated to your exact industry and target audience, simulates how they interact with your design, and returns a prioritized issues breakdown — in under 30 seconds.
Input: Paste a Figma prototype link or live URL → define your industry, business model, and target audience.
Process: AI generates 3–5 personas that match your market context. Each one simulates interaction with your design and surfaces friction points based on who they are.
Output: A dashboard showing persona-by-persona feedback, an issues breakdown ranked by severity and business impact, and a UX score. Every session is saved to version history so you can fix, re-test, and track improvement.
