AI-native CTO for early-stage founders
I built the tech behind Endomondo (exited to Under Armour) and Simple Feast. Now I bring that same senior judgment to your MVP — faster, because I build with AI.
My Services
Using AI and decades of startup experience, I turn ideas into market-ready products faster and more efficiently.
CTO Services
Bring an experienced CTO on board to guide your tech strategy, avoid costly mistakes, and translate business ideas into the right product features.
AI Product Development
I build AI-native products fast, so you can launch, learn from users, and move toward product-market fit. Using AI-powered development workflows, I accelerate delivery without compromising quality.
From UX/UI and architecture to deployment and iteration, I cover the full product development process.
AI Automation
I build AI automations that remove repetitive work, streamline workflows, and save time across your business.
How I Work
I don’t just build your product — I become part of your journey.
To align incentives, I prefer to share in the success of the startups I work with, combining project-based pricing with revenue share or equity.
Past Work of CEO Thomas Stilling Ambus
I’ve been in your shoes. As a founder and CTO, I’ve built startups from scratch — writing the first lines of code, growing teams, and scaling products into successful businesses. I know exactly what it takes to bring an idea to life.
