Engineer better proteins, faster, with AI
Start from a target or your own sequence and have Cradle design an optimized plate of candidates informed by your data and domain knowledge.
Improve efficacy, developability, and manufacturability in parallel rather than one property at a time, compressing time to a target profile.
Every round incorporates results from the previous one, so experimental data compounds across campaigns and prior failed programs stay useful.
Everything in the web application is exposed through the API, so computational teams can script campaigns and wire Cradle into existing pipelines.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
