May 19, 2026 | By Startuprise io

Violet Therapeutics, a Somerville, MA-based preclinical-stage biotechnology company, has raised $4.75 million in a Seed extension funding round led by Lifespan Vision Ventures, with backers including Dementia Discovery Fund, UTEC, Ono Venture Investment, and Mass General Brigham Ventures.
The company plans to use the funding to advance its lead small-molecule program targeting EphB3 and to support important IND-enabling development activities.
Violet Therapeutics is a preclinical-stage biotech company developing new treatments for neurodegenerative diseases. The company studies how brain cells communicate to understand better the causes of neuroinflammation, neurodegeneration, and synaptic loss. Its proprietary CONNECT platform is designed to identify key signaling pathways in the brain that could serve as targets for future therapies.
Synaptic loss is one of the main drivers of cognitive decline in Alzheimer’s disease and other neurodegenerative conditions. Violet Therapeutics’s lead program aims to address this by focusing on glial mediated synaptic preservation, and repair.

The company’s CONNECT platform helps identify how glial signaling contributes to synaptic dysfunction, with EphB3 identified as an important first step toward potential brain-protective therapies.
