Solidkosmos closes $336K seed led by Corallia Ventures to commercialise SK-RAFT
What's the deal? Solidkosmos, the first spin-off from the University of Piraeus Research Centre, has closed a $336K seed round led by Corallia VenturesDealroom has a profile for this one. Try Dealroom →. The funding will commercialise SK-RAFT, a software tool that injects and simulates faults in real computing hardware to verify the reliability of critical systems used in space, defence, data centres, and AI.
Why now? The global electronic design automation (EDA) tools market exceeds €20B annually and is growing fast, driven by AI infrastructure, expanding data centre capacity, and increasingly complex space systems — all of which demand rigorous reliability testing.
Current verification methods force engineers into a difficult trade-off. Software simulations are slow and struggle to capture the behaviour of complex hardware-software systems. Physical tests — radiation, electromagnetic interference, laser fault injection — yield reliable results but require specialised facilities, high costs, and long lead times.
SK-RAFT bridges that gap by letting development teams run fault-injection campaigns directly on real hardware through debugging interfaces, without needing access to specialised labs. This allows systematic verification of fault detection, isolation, and recovery mechanisms at multiple stages of the development cycle.
What could go wrong? Solidkosmos is entering a market dominated by well-resourced incumbents. Convincing space and defence customers — industries with long procurement cycles and stringent certification requirements — to adopt a tool from a seed-stage startup is a steep challenge. The modest funding also limits how quickly the company can build a sales presence across global markets.
The signal: Solidkosmos is an ESA BIC incubatee, underscoring that Europe's institutional space ecosystem is increasingly channelling early-stage capital toward niche deep-tech tools — not just launch vehicles and satellites. Corallia Ventures' bet suggests that as sovereign space and defence programmes expand across the continent, investor appetite is growing for the verification and testing layer that underpins hardware resilience.
