Compounding results

Move from incremental progress to compounding results with models that learn from every round of your wet lab data. Teams that use Cradle report 1.5-12x faster development timelines.

Breakthroughs on repeat

Following a single path puts you at risk of hitting a dead end. Instead, confidently explore multiple design strategies to bring more programs over the finish line and strengthen your IP portfolio.

Co-optimize all your properties

Activity, binding, stability, expression, and more. Co-optimize the properties you care about, turning complex trade-offs into optimized solutions in fewer rounds.

WORK ON ANY PROTEIN

Built for any protein and all properties.

Import your data

Import your data

To begin, upload wet lab data from screening or optimization experiments. If you're starting a project from scratch, simply define your goals and assays to get going.

Explore your data quality

Explore your data quality

Cradle automatically analyses your experimental data to determine data quality and AI’s ability to learn from it. This helps you to understand areas to improve your workflows and assays to get to optimal sequences faster.

Models learn with you

Models learn with you

Every time you upload lab results, Cradle gets better at understanding your protein. This means increasingly performant variants that get you closer to your goals— every round.

Generate candidates

Generate candidates

The game-changer of Cradle: new, optimized candidates at the click of a button. Choose a design strategy, set sequence- or lab based constraints, bring in your knowledge of the protein and hit ‘Generate’. No PhD in computer science needed.

Multi-property support

Multi-property support

Cradle learns the complex interactions between all properties of your protein. During generation, this translates into candidates that balance improved performance across properties with high scores on diversity and novelty

Full-plate optimization

PRIVATE. SECURE. YOURS

With Cradle, your sequences and data remain private, secure, and entirely yours. Only you and those you invite can access your data, which is never used to train models for others. Protected by bank-grade security, your data stays secure at all times.

Plus, you retain full ownership of your intellectual property—no royalties, just a software subscription fee.

THE CRADLE LAB

AI that gets better
every two weeks.

Cradle isn’t a CRO, so why do we run our own wet lab in Amsterdam?

It's simple. So you get reliable and high-performing models from day one, while your proprietary data remains completely private. 

Much like a self-driving car company: they wouldn’t just design algorithms and cross their fingers. They need to test real-world scenarios and collect data in order to fine-tune performance. We take the same approach, ensuring our models are performant even before seeing your data.

You made it. Nice.
