Lightbase closes €2.2M pre-seed round, launches AI developer tool

Madrid-based Lightbase, an AI-powered developer tools platform, announced its official launch along with a €2.2 million pre-seed funding round. The investment will fuel Lightbase’s mission to accelerate the pace at which engineering teams deliver value by eliminating one of their most persistent bottlenecks: knowledge fragmentation.

The round was led by Picus Capital, with participation from Kfund, Helloworld, and angel investors Jorge Poyatos, Albert Nieto, Christian Beedgen, and Rodrigue Schäfer.

In growing engineering organisations, the real productivity bottleneck isn’t writing code, it’s finding and sharing the knowledge needed to change it. Developers spend roughly a third of their time coding, with the rest lost to meetings, interruptions, and coordination. Senior engineers carry the heaviest load, fielding questions and mentoring. The problem deepens with new hires, who face a steep learning curve and remain dependent on teammates because there’s no reliable, self-serve way to navigate the codebase. When experienced engineers switch teams or leave, critical context disappears, creating costly, hard-to-close knowledge gaps.

Lightbase, an AI-powered code intelligence platform, solves this by turning codebases and engineering tools into a living knowledge system. It plugs directly into repos and workflows, analyses the code, and uses AI to deliver instant, accurate answers about how your systems work, far beyond what generic AI coding assistants provide. The result: fewer interrupts, faster onboarding, preserved institutional knowledge, and a meaningful lift in real engineering throughput.

As teams scale and systems grow more complex, Lightbase gives engineers, product managers, and new hires rapid insight into architecture, data flows, and dependencies. This reduces constant pings to senior developers and can free up to 50 per cent of time lost each week to onboarding, meetings, and repeated explanations.

This pre-seed investment will accelerate Lightbase’s product development and expand its engineering team. Following strong results with early customers, Lightbase is opening its platform to more companies across Europe and North America.
