Tessel is building the evidence infrastructure for safety-critical AI: the system that proves a model works and keeps proving it. The biggest challenge in safety-critical sectors isn't building models that beat benchmarks. It's producing and structuring the evidence to continuously demonstrate to regulators, governance boards, patients, and insurers that a model is safe and effective in real-world use. We partner with diagnostic imaging AI companies and academic medical centers to rethink how validation evidence is produced and used today. By bringing the rigor of safety cases to AI, we make assumptions visible, surface failure modes, and turn validation work into a systematic process. The result is a platform for continuous monitoring and improvement, one that iteratively closes the gap between validation and patient outcomes.
