Seed Round Capital

Seed Round Capital is a Houston-based early-stage venture firm founded in 2021 by operator-founders. It invests at the pre-seed stage in US deep technology and dual-use startups - companies whose products draw on hard science and engineering and are applicable to both commercial and government markets. Sectors of focus include defense, space, materials science, energy and biotechnology.

The firm's typical cheque is $50,000 to $250,000, and it has made more than 80 investments since inception. It frequently co-invests alongside other specialist investors, a pattern consistent with its stated focus on technically complex companies that generalist investors struggle to evaluate. The investment thesis places weight on defensible founder know-how, capital efficiency and credible paths to commercial or government markets.

Alongside capital, Seed Round Capital provides operational guidance, expert introductions and access to co-investors. It also advises founders on linking equity fundraising to non-dilutive programmes - notably SBIR and DARPA - and on translating prototypes, grants, pilots and technical milestones into an investor narrative. This combination reflects the capital structure of the sectors it targets, in which government grants and venture funding are often sequenced together.

The firm is based in Houston, Texas and operates across the United States.
