01Binder formats + scientific methods

Science, not secret sauce.

Choose the binder format that fits the biology, then run a leading scientific method built for it—from antibody fragments and de novo miniproteins to linear, cyclic, and stapled peptides.

Start with a target structure, define the interactions that matter, and run the original methods through guided interfaces. The controls stay visible, and structures, scores, and intermediate designs stay organized.

BindCraft2 builds on the method that inspired Ariax, bringing faster campaigns and more therapeutic formats. Academic and commercial users pay only for compute, with no separate BindCraft2 commercial license required on Ariax.

Antibody-derived: Fab · scFv · VHH / nanobody
Protein binders: Large binders · miniproteins · ankyrin repeat
Peptides: Linear · cyclic · stapled α-helical / helicon

02Guided workflow

Design the binder your program needs.

Choose a therapeutic format, prepare the target, and move from scientific intent to ranked designs through one guided workflow.

Start with the structure

Prepare the biology that matters.

Upload a structure or find one through RCSB, choose the relevant chains and residues, and inspect the target before starting a design campaign.

03On-demand GPUs

Enterprise GPUs on demand.

Run modern binder-design campaigns without waiting for a shared cluster queue or requesting a larger quota.

Launch one binder design or ten immediately. Ariax runs each campaign on modern NVIDIA GPUs and charges only for the GPU compute it uses—no platform subscription or quota approval required.

GPU availability varies by workflow and changes with demand; some GPU types are easier to provision than others.
