Developing custom chemical additives that enhance microbial metal extraction from existing mining operations and waste, Transition Metal Solutions has raised 6 million dollars in Seed funding in a round led by Transition Ventures.
The round included participation from SOSV, Dolby Family Ventures, Astor Management AG, Juniper VC, Climate Capital, Possible Ventures, Understorey Ventures, New Climate Ventures, Essential Capital and Kayak Ventures.
Led by CEO and founder Dr. Sasha Milshteyn, the Berkeley, California-based company develops custom chemical additives that enhance wild microbial communities to improve metal extraction.
Its platform analyzes the biology already at work in a mining operation and formulates targeted products that increase recovery and accelerate extraction without requiring new infrastructure or changes to existing processes. Starting with copper, the technology is designed to extend to other critical minerals.
The company intends to use the funds to scale its technology from lab to industrial pilot conditions, with 3-meter column trials targeted to start in the first half of 2026.
