“The difficulty of that research became the problem I set out to solve.”

Yann Strainchamps founded Geyserich in Luxembourg. At 17, he was given access to a family genealogical archive on Geneanet — he expanded it, verified through state archival records and independent genealogical confirmation, traced to the 13th century.

Geyserich is raising a pre-seed round. We are building the foundational data layer for European heritage — a market worth $4 billion with no dominant European player.

If you are an investor interested in deep tech, cultural data infrastructure, or European heritage, we want to hear from you.
