AI-Guided Enzyme engineering

Optimize activity, expression, and thermostability in the same enzyme optimization campaign.

Run multi-property optimization across every property your team measures — trained on your own assay data. Reach a variant that meets your full target profile in fewer rounds.

Every enzyme engineer knows the pattern.

Your best Round 4 variant has 3× activity — and 40% lower expression. Your +15°C Tm hit doesn't tolerate process pH. The two best single mutants combined perform worse than either parent. And your assay drifted between batches, so half your data is noise.

Directed evolution optimizes one property per round. Rational design from a crystal structure misses the distant positions that drive real-world performance. Combining single winners ignores epistasis.

Cradle was built for teams past the screening hit. The goal is to get you to a variant that holds up at scale.

Fewer rounds

Stop running dozen-round directed evolution campaigns

Cradle is built to handle the realities of the lab—like assay noise and batch-to-batch variation—that usually stall engineering. Scientists reach target profiles 2-12x faster using as little as one 96-well plate of data. You get to the "winner" faster while spending less on synthesis and screening.

Better enzymes

Optimize for activity, stability, and expression in parallel

Stop choosing between a high-performer that won’t express and a stable lead with no activity. Cradle balances these trade-offs from round one, finding non-intuitive mutations that traditional rational design misses. You get a diverse set of sequences that aren't just "hits" in an assay, but viable candidates for production.

Built for biologists

An intuitive workbench for any enzyme class

Your team can run campaigns directly through a UI that combines 3D structural views with sequence insights—no coding or data science degree required. Whether you’re engineering P450s or polymerases, you maintain full control of the strategy. Most importantly: your sequences and models remain your exclusive IP.
