Roh Ventures is a deep tech family office. We bring patient capital and practical partnership to founders building frontier science into durable companies.
We invest at pre-seed and seed, when the work is still experimental, timelines are long, and conviction matters more than consensus. We back teams translating fundamental research in hard science and engineering into products, systems, and companies that can scale and endure.
Pre-seed and seed investments in companies building at the edge of science and engineering.
Alongside aligned funds, operators, and strategic partners when it strengthens the company's path to adoption.
Select venture studio style partnerships. We can work from day zero on company formation, technical milestones, early hiring, and the first path from prototype to product.
