Key features	AI protein candidate generation from desired properties Multi-property co-optimization (activity, binding, stability, expression, custom) Models retrain on every round of a customer's own wet-lab data Custom organization-specific predictor models SOC 2 compliance and SSO for enterprise biopharma teams	Multi-modal real-world data integration Interpretable machine learning models Discovery, validation and deployment coverage Enterprise-scale data processing Fits existing workflows with no new assays required
Pros	Structural data privacy - customer data never trains models for other customers Multi-property optimization handles real-world tradeoffs, not just one target metric Reported 2-12x faster development timelines is a substantial claimed impact	Interpretable models, which is what makes a target hypothesis actionable Works on data already generated rather than requiring new collection Covers the therapeutic lifecycle rather than one stage
Cons	No published pricing - enterprise sales process only Requires an existing wet-lab pipeline generating experimental data to retrain against Built specifically for biopharma/biotech R&D, not accessible to individual researchers	No published pricing, contact only Real-world data carries the biases of who received care and where Findings need prospective validation before changing clinical decisions
Company	Cradle	Zephyr AI
