Building a Bold New Path for Ultra-Rare Diseases
We bring the infrastructure, capital, and expertise needed to turn patient-led breakthroughs into approved medicines at scale.
The Problem
The Science Is Ready. The System Is Not.
Rare disease is not a monolith. Rare diseases are often treated as a single category, but in practice, they fall into two fundamentally different groups with very different development realities.
Larger Rare Diseases
Between 3,000 – 200,0000 patients
For a small subset of rare diseases, patient populations are large enough to attract significant therapeutic development. Many of these conditions now have approved therapies but face challenges around pricing, access, and reimbursement. The core issue here is not whether medicines can be developed, but whether patients can access them.
Ultra-Rare Diseases
Less than 3,000 patients
Ultra-rare diseases represent a very different problem. Most have:
- A known genetic cause
- A clear therapeutic hypothesis
- Small, well-defined patient populations
Yet the vast majority have no active therapeutic development programs at all.
Our Solution
A New System for Ultra-Rare Medicine Development
Buffalo applies proven models from technology and finance—accelerators, portfolios, and blended capital—to transform ultra-rare therapeutic development from exceptional to repeatable.
We don’t just fund programs.
We are building the ecosystem that delivers them.
Pipeline
Continuous identification of high-quality, patient-led programs
Accelerator
Expert support to move from preclinical to patients
Open Source
Shared playbooks that make every program faster
Blended Capital
Financing aligned with biology, not short-term exits
