A platform, not a single assay
Our technical foundation spans bacterial, yeast, insect and mammalian cell-free expression, allowing the expression environment to match the molecule and experiment.
Investors
Building the expression infrastructure behind the next generation of biology.
Protein design is accelerating. Experimental validation and manufacturing still move at the speed of cell culture. Liberum is building cell-free systems that close that gap across bacterial, yeast, insect and mammalian biology.
Liberum is rapidly becoming the expression infrastructure behind AI labs, cloud labs and next-generation protein discovery.
Sequence generation is becoming abundant. The scarce layer is turning those sequences into physical molecules and reliable experimental data quickly enough to keep pace.
Why now
Labs are generating more designs than they can physically test.
Built for experimental loops
Liberum connects sequence generation to physical protein and measured phenotype, creating infrastructure for directed evolution, automated laboratories and AI-driven protein engineering.
Products already emerge from the platform
Antibody-fragment reagents are available through cell-free.com, while Fynd extends our mammalian technology into rapid full-length IgG production.
From discovery to responsive manufacturing
The same core capability supports affinity maturation and experimental data generation, antibody production, and rapid vaccine antigen manufacturing.
Intellectual property
Building a defensible cell-free technology platform.
Liberum has four active patent filings protecting core aspects of our technology platform. Additional details are available under confidentiality as part of investor diligence.
Backed to build
Supported by investors who understand the scale of the opportunity.
Liberum is backed by SOSV, TechU Ventures and a large pharmaceutical company. We are building toward a world where protein expression is infrastructure, not a bottleneck.
