Where others see science fiction, we see a blueprint.

Roh Ventures is a deep tech family office. We bring patient capital and practical partnership to founders building frontier science into durable companies.

Our investment thesis

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.

How we engage

Invest

Pre-seed and seed investments in companies building at the edge of science and engineering.

Co-invest

Alongside aligned funds, operators, and strategic partners when it strengthens the company's path to adoption.

Co-build

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.

We are most useful when

  • The technical risk is real and the adoption path is non-linear
  • The first product is a prototype, not a pitch
  • The work needs time, iteration, and disciplined validation
  • The upside is structural and long-term
