Founders and UI/UX Designers are true visionaries. They build with conviction, yet they often struggle to validate user experiences against the complex needs of their power users. This disconnect is the single biggest reason why otherwise useful solutions fail to achieve Product-Market Fit.

We bridge this gap with a platform that allows builders to stress-test their products using agentic personas. These agents do more than just observe; they emulate real user behavior, interact with the solution, and provide tangible, actionable feedback.

We don't just identify the problem, we help fix it. By leveraging the Gemini CLI, we close the development loop, automatically generating Pull Requests (PRs) to implement incremental improvements based on agent feedback. Build, test, and iterate your solution faster than ever, securing your quality before you even secure your first user.
