About Kuro

Kuro was founded by Lea & Jonas, who’ve built construction tech scale up alcemy and Capmo before. Kuro is building the AI automation platform for construction companies. We help construction professionals to utilize their biggest data source - the 95% of unstructured data. Our entry is in the estimation (quoting) process, the core and most expensive back office process. Our product extracts information from the project input, identifies building components automatically and enriches it back into a 3D model. Saving up to 90% time.

Leading construction enterprises with a combined construction volume >30 billion annually use Kuro already today.

We just raised a pre-seed round from the leading global construction tech VC and are looking to grow our team in Berlin. You would be one of our first hires - we’ve been early employees before. Joining an early stage startup was the best decision we ever took and we are excited to pay it forward.
