Optimize multiple objectives at once

Set the required objectives for your protein. Then generate proteins that satisfy these objectives, improving activity and developability in every design cycle.

De-risk earlier

Generate sequences that are free from undesirable motifs. Avoid post-translational modifications and eliminate immunogenicity or toxicity liabilities before taking your designs to the lab.

Design for real-world function

Don’t stop at binding. Incorporate data from downstream functional assays—including cell surface binding, reporter signaling, or cAMP assays—to guide the next round of optimization.

Works with any format and assay

Cradle plays well with your experimental data - no matter the source. Import NGS data from screening campaigns, or raw experimental results from downstream assays.

Train AI throughout your program

Connect the dots and maximize learning throughout your program and across your organization. From early discovery datasets to your final assays, and from positive hits to negative results, Cradle ensures that no experimental data goes to waste.

No historical data? No problem.

Start a new program with as little data as a single sequence.

Protein design at any level of expertise

Use Cradle with simple defaults, or set advanced design requirements based on your in-house expertise.

Simple workflows

Run Cradle through its user interface, or exercise more control via the API. Don’t have extensive computational expertise? No problem–we have a team of advisors and engineers to help guide your approach.

Mutations where you want them

Specify where to allow changes in your protein - whether on the surface, in antibody CDRs or regions that you define. You can apply precise rules to steer clear of known liability motifs and ensure that sequences are compatible with downstream reformatting or conjugation.

AI your whole team understands.

Quickly generate clear, actionable reports to analyze your data and understand model performance, giving you the confidence you need before taking sequences into the lab.

Works on any biologic and all properties

Antibodies

Peptides

Vaccines

A flexible starting point for your program

Antibody projects can be started from a single weak binder sequence (see our participation in the Adaptyv competition) or existing datasets.

Affinity maturation with developability in mind

Improve binding by introducing targeted mutations in CDRs or framework regions—without sacrificing stability, manufacturability, or other key developability traits.

Maximum value from discovery libraries

Upload NGS or ELISA screening data from immunization campaigns and display technologies, then use Cradle to supplement your library with diversified binders. Learnings from this discovery phase continue to boost performance, even after reformatting.

Early liability mitigation

Generate sequences that are close to germline, away from immunogenic motifs, or free from specific isomerization and oxidation sites. Incorporate data from in vitro or ex vivo assays for immunogenicity and toxicity.

Optimize for efficacy, not just binding

Beyond binding, optimize efficacy using data from functional assays including cell surface binding, reporter signaling, T-Cell activation, or cAMP assays.

Set antibody-specific objectives

Set configurable objectives when generating sequences. These can be absolute or relative - think on-rates, off-rates, preferential binding, specificity, cross-reactivity, and more.

Fine-grained control over new mutations

Cradle gives you control over where along the antibody sequence to allow new mutations, and which specific amino acid residues or motifs to block or enforce. This allows you to explore diverse sequences free from known liabilities.

Support for diverse antibody formats

Formats that are within scope for Cradle include antibody fragments (VHH, scFv, Fab), full-length IgG, as well as bi- or multispecifics, and Antibody Drug Conjugates.
