PMWC 2027 · Silicon Valley
Atul Butte Company Competition
The PMWC Most Promising Company Competition returns in honor of Atul Butte, celebrating evidence-first startups that turn data into care and giving rising companies a stage before leading investors, clients, and partners.
In memoriam
A meaningful check, and a much bigger stage.
The winner is announced on stage at the end of competition day. The prize is brought to the PMWC community by OpenEvidence.
Who can apply
Built for rising precision medicine companies
Privately held startups from Seed through Series A are invited to apply. The competition launched in 2009 to spotlight emerging companies with the science, team, and execution plan to change care.
Diagnostics
Tests, biomarkers, platforms, and clinical tools that improve detection, stratification, monitoring, or treatment selection.
Therapeutics
Drug, biologic, cell, gene, or platform approaches that address a clear unmet need with differentiated evidence.
Health Tech
Products and infrastructure that make precision care more actionable, scalable, measurable, or accessible.
AI & Computational Medicine
The new category for evidence-backed computational platforms that translate data into clinical or therapeutic decisions.
Competition format
One day. Two stages. Three finalists.
The format is deliberately fast. Companies must explain the need, evidence, product, and path forward without a fog machine or a 47-slide origin story.
Submit the company
Applications are free. Selected companies will be published and promoted in December 2026.
Semi-finals
Each selected company receives a 5-minute presentation followed by 2.5 minutes of judge Q&A.
Top three announced
The finalists advance to the afternoon finals and present on the PMWC main stage.
Winner and $20,000 prize
The winner is announced live and receives the OpenEvidence-sponsored award check.
Final-round judges
Investors and builders who knew Atul
The finals are judged by people who understand both Atul’s standards and the unglamorous work required to move a promising idea into patient impact.

The name behind the competition
A builder who made data answer to patients
Atul Butte, MD, PhD (1969–2025) was a physician scientist and biomedical informatics pioneer who helped define modern evidence-first precision medicine, showing how large-scale clinical and molecular data could be translated into decisions that improve patient care.
He held leadership roles at Stanford University and Lucile Packard Children’s Hospital, including Chief of the Division of Systems Medicine, with faculty appointments spanning Pediatrics and Medicine and a courtesy appointment in Computer Science.
At UCSF, he became the inaugural Director of the Bakar Computational Health Sciences Institute and served as UC Health’s inaugural Chief Data Scientist, helping unify data-driven approaches across the University of California academic medical centers.
Beyond academia, Atul was a founder and mentor focused on real-world clinical impact. He co-founded Personalis, NuMedii, and Carmenta and inspired a generation of builders to combine rigorous evidence with practical translation.
