Founder building at the intersection of product thinking and AI. I've spent years in product management watching brilliant people build things nobody wanted — so I'm building the tool that stops that from happening. Currently building Buildworthy in public. Based in Bangkok.

Things I'm working on

Buildworthy

Buildworthy is an AI-powered validation tool for SaaS founders and product teams. It maps your riskiest assumptions, designs a real-world experiment for you to run, tracks your results, and gives you a Buildworthy Score — a clear, evidence-based verdict on whether to build, pivot, or kill your idea. Unlike every other validation tool, Buildworthy doesn't stop at an AI report. It pushes you toward a real payment signal — because interest is cheap, and the only assumption that matters is whether someone will pay. Currently pre-launch. Waitlist open at getbuildworthy.app/ih
