About Biomemory
Biomemory, founded in 2021, boldly stands at the crossroads of Biotechnology and Computing, driven by a passion for sustainability.
We are a well-funded start-up building IT rackable equipment for Data Centers, using synthetic DNA as the storage media. While this technology is still at its infancy, these DNA Data Storage Servers target the storage of massive amount of data (Exabytes) with a very long retention life-time (> 100 years) within an attractive capex and opex budget.
Headquartered in Paris, Biomemory aims at serving the fast-growing international “cold-storage” market.
After securing a €17M Series A in early 2025, we are now entering a high-growth phase, aiming to more than double our team from 25 to 50 by the beginning of 2026.
Join us in rewriting the future of data storage!
