Giving medicine a shared
understanding of every patient
The molecule got faster.
Clinical reasoning didn’t
Medicine accelerated everywhere except where therapies meet patients. Every new therapy still depends on someone manually understanding years of fragmented patient history.
Target selection, molecule design, protocol authoring. Everything upstream of the patient has compressed, year over year.
At the record. Eligibility is still answered by hand, one file at a time — which makes patient data the rate-limiting step of the whole enterprise.
A trial that fills on time is a therapy that arrives sooner. For the patient in it, and for everyone treated after them.
Building the missing layer between patient records and AI
With Mosaic we turn routine clinical documentation into a structured, longitudinal and cited patient history that frontier AI can reason over. We do not replace the EHR. We make what is already inside it readable by machines.If we get this right, clinicians spend less time reading records and more time deciding: a trial found while it is still open, a progression caught at the visit where it matters.
