Interface Fund

Interface Fund is a pre-seed and seed-stage venture capital firm investing at the intersection of physics and biology, backing scientific and engineering pioneers reimagining critical sectors of the world. Founded in 2022 by Managing Partner Julia Prakapovich, the firm is headquartered in San Francisco, California. Its sector focus spans techbio, computing, infrastructure, human augmentation, neurotech, and hardware-biology convergence, with Prakapovich positioning herself as a hands-on co-creator rather than a passive capital provider. Investments include Motif Neurotech, Science Corp, Thornhill Therapeutics, Harmony Intelligence, and an early stake in SpaceX. Interface Fund typically writes first checks in the range of $500,000 to $1 million, with its approach centered on backing ambitious founders early and staying deeply engaged as both investor and operational collaborator.
