Estonian AI app-building platform bilt.me has raised $700,000 in pre-seed funding in a round led by Superhero Capital, with backing from Bolt founder Markus Villig and Lightyear founder Martin Sokk.
Founded in August 2025 by Uku Joost Annus, Kevin Akkermann and Karl Kiilaspää, bilt.me is developing an AI agent that takes users from an initial idea to a live mobile application. The company started as a hackathon project focused on overcoming Apple's app-testing restrictions and later evolved into a platform designed to make native app development accessible to more people.
Unlike AI app builders that primarily generate web applications, bilt.me focuses on native iOS and Android apps. The company sees an opportunity in reducing the technical barriers to mobile app development, enabling people with ideas to build and launch products without going through the traditional development process.
Our bet is that apps, not websites, are where the next generation of businesses gets built,
said Annus.
Building native applications also required the company to develop supporting infrastructure. With what it saw as a lack of suitable tools on the market, bilt.me built its own payments, cloud and sharing layers, called Bilt Payments, Bilt Cloud and Bilt Link.
The platform has passed six figures in annual recurring revenue, with revenue doubling month over month for three consecutive months. Thousands of people are using bilt.me to build applications, around 75 per cent of which are consumer apps and 25 per cent private or in-house tools. Paying apps built on the platform are also live on the App Store and Google Play.
The company sees an opportunity for Europe at the application layer of AI, with Annus pointing to Europe’s lagging position in areas including energy, semiconductors, AI infrastructure and frontier AI models.
But there's one layer where Europe is still world-class: the application layer, turning AI into things real people use and pay for. That layer runs on builders, and we don't have nearly enough of them. Everyone told us the magic was in San Francisco. We went, and came home more convinced than ever that the builders are already here.
Annus also pointed to how users are turning their knowledge and ideas into products and businesses through the platform.
Our users are living at the frontier of AI. They take knowledge only they have, solve a problem everyone shares, and build a real business out of nothing in almost no time.
bilt.me will use the new capital to support its global expansion and further develop its application-building capabilities.
