Our Mission
To build the value infrastructure for healthcare AI - so promising technologies can move from validation to adoption, funding, and real-world impact.
We believe AI will only transform healthcare if its value is credible, comparable, and visible to those who decide whether it is adopted.
Our Approach
We combine structured AI value assessment with real-world market intelligence.
Through the VIS Platform, we help stakeholders define AI use cases, assess value and readiness, navigate complex market realities, and make informed decisions - grounded in evidence, context, and system-level understanding.
Our Commitment
We are committed to responsible, transparent, and sustainable AI adoption in healthcare.
This means:
Evidence that is scientifically rigorous and context-aware
Decisions informed by real-world signals, not hype
Alignment with clinical needs, health system priorities, and public trust
We work with stakeholders across the ecosystem to ensure AI delivers meaningful and lasting impact.
