01 Our technology
The right phage.
The evidence behind it.
Bacteriophages are viruses that infect bacteria. We connect sequence intelligence with laboratory evidence to turn a bacterial target into a practical phage solution.

02 / Phage–host prediction
Find the match
in the data.
Machine learning supports phage–host prediction, helping us prioritize candidates for the bacterial target and the next stage of testing.
03 / Laboratory evidence
Put promising
candidates to the test.
Isolation and characterization connect predictions to experimental evidence, building a clearer picture of each phage and its host range.
One connected process, from digital discovery to work in the lab.

Coming soon Mobile GMP production
Production closer
to where it’s needed.
We have started a collaboration to develop small mobile laboratory units for on-site production under Good Manufacturing Practice (GMP).
The planned settings span our headquarters at BioCampus Cologne Tech Park, hospitals already providing phage therapy, and remote locations supporting responses to future outbreaks and pandemics.

Harnessing phages.
Expanding possibilities.
BioCampus Cologne Tech Park · Cologne, Germany
Phagestack’s mission is to harness bacteriophages for human and animal health, agriculture, and aquaculture.
We combine over a million curated phage sequences with machine learning for phage–host prediction, turning data into targeted phage solutions—from isolation and characterization to production and deployment.
