## About

T.Rx Capital is a private equity firm headquartered in Boston, Massachusetts, specializing in early-stage investments. The firm targets seed and startup-stage companies, focusing its origination engine on the intersection of healthcare services, digital health, and life sciences technology, a profile consistent with the dense biotech and academic innovation cluster that defines the Cambridge-Boston corridor. The firm's strategy centers on direct equity investments at the earliest phases of company formation. Its mandate covers seed rounds and startup financings, positioning T.Rx Capital to enter cap tables alongside angel syndicates and pre-seed venture funds. T.Rx Capital operates a lean structure, consistent with firms deploying niche capital into technical seed-stage ventures. While specific professional headcount and the names of its investment partners have not been widely published, the firm's Boston location places it within the New England life-sciences and academic-origination ecosystem. The firm maintains no other publicized adjacencies such as philanthropic foundations, operator networks, or real-asset subsidiaries. The firm's structural differentiator lies in its discretion. T.Rx Capital operates without the media footprint of a traditional institutional fundraiser, a model that can offer founders a quiet capital partner during the fragile seed and startup phases of company building where competitive visibility is often unwelcome.

## Questions

### Who runs investment decisions at T.Rx Capital?

The four Co-Founding Managing Partners — Dr. Robert Langer (Executive Chairman), Dr. Kwesi Frimpong-Boateng, Michael Langer, and Dr. Corey McCann — collectively lead investment decisions. Venture Partners Dr. Liz Kwo and Dr. Debbie Lin contribute deal sourcing and diligence support. The advisory board, which includes Third Rock Ventures founder Mark Levin and former Pfizer Chief Medical Officer Freda Lewis-Hall, provides scientific and strategic counsel on opportunities.

### How does T.Rx Capital source proprietary deal flow?

The firm's primary sourcing advantage flows from Executive Chairman Robert Langer's MIT laboratory, the largest biomedical engineering lab in the world with over 100 researchers and $17 million in annual grants. His network of 1,500 patents licensed to more than 400 companies, plus the other partners' relationships across Eli Lilly, Pear Therapeutics and McKinsey, creates an early-stage healthcare pipeline that is difficult for generalist seed funds to replicate.

### Which sectors does T.Rx Capital explicitly avoid?

T.Rx Capital does not publish an explicit exclusion list. Given its exclusive focus on healthcare, the firm implicitly avoids consumer, enterprise software, industrials, and other non-health verticals. Within healthcare, the disclosed portfolio — Recuro, Zus, a radiopharmaceuticals company, and a pain NewCo — signals conviction across biotech, digital health, and medtech without an obvious avoidance of any subsector.
