Life sciences venture capital firm RiverVest Venture Partners today announced the closing of Archer Seed Fund, LP, at $15 million. 

The Archer Seed Fund will invest “modest amounts” of pre-seed and seed funding in about 10 early-stage biopharmaceutical companies, according to RiverVest Managing Director John McKearn, PhD, in a press release. The fund’s investment opportunities will be primarily sourced from business incubators or accelerators associated with leading medical research institutions in St. Louis and elsewhere in the Midwest.

Capitalizing on the strong local infrastructure for startup companies, including Cortex Innovation Community and BioGenerator, the early-stage development activities for most of these seed companies are expected to be conducted in St. Louis.

“With top research institutions like Washington University and Saint Louis University, communities dedicated to innovation, and an abundance of skilled talent, St. Louis is a magnificent place to grow early-stage biopharma companies,” said Dr. McKearn. “Archer will not only benefit from St. Louis’ assets, it will also accelerate and contribute to our startup ecosystem.”
