Fly with us

Our mission is to give hope to patients of 'undruggable' neurodegenerative diseases and cancers.


We searched where none had gone before to find the missing data to unblock drug design for intrinsically disordered proteins.






Find the missing data for drug discovery.

Analyse what microgravity reveals.

Work with our MB-X automated platform to run reveal protein states obscured at 1g.

Map dark proteome interactions.

Access the HI-PROT atlas of microgravity revealed protein structure to function data.

Model & design with SpaceFold.

Licence SpaceFold to supercharge foundational models and accelerate discovery.

Microgravity creates conditions irreproducible on Earth.

Around half of our proteins are IDPs with no fixed shape for drugs to target. They are kryptonite to AI.



On Earth, gravity-driven sedimentation and convection blur their behaviour. In orbit, those forces disappear.


No sedimentation

Protein assemblies remain suspended long enough to observe their native behaviour.

No convection

Removing gravity-driven flow reveals molecular interactions without turbulence.

Diffusion-limited

A quieter environment lets weak molecular signals emerge with unusual clarity.
