constellr has raised 37 million euros ($44 million) through a new Series A funding round to advance its thermal intelligence capabilities. The round was led by Alpine Space Ventures and Lakestar. constellr announced the new funding round, Feb. 10.

The investment will accelerate the expansion of constellr’s fully operational thermal intelligence capabilities and advance the system to defense-grade status for governments, military entities and security agencies. constellr aims to close what it calls a critical gap in Europe’s sovereign intelligence, surveillance, and reconnaissance (ISR) architecture. Its high precision thermal intelligence adds the behavioral insight layer, revealing what assets are doing and why, complementing radar’s structural mapping and optical imaging’s visual classification.

constellr’s technology aims to deliver earlier detection, independent verification, and highly reliable assessments of activity in contested or deceptive environments. Defence and security forces can then uncover hidden operations, track non-cooperative assets, and anticipate deployments before they occur, even where conventional monitoring is impossible.

“Sovereign resilience requires understanding real activity on the ground, not just seeing objects. Thermal intelligence provides the earliest and most reliable signal of operational change, from detecting rocket and airbase activity to identifying active reactors and hidden industrial operations. Europe must own this capability. constellr is already delivering operational intelligence today, and this funding accelerates our path to full defence-grade performance to close critical gaps in Europe’s sovereign ISR architecture,” Max Gulde, CEO and co-founder of constellr, said in a statement.
