America's Seed Fund (NSF SBIR/STTR): Non-Dilutive Funding for Research-Driven Startups

America's Seed Fund, run by the U.S. National Science Foundation since 1977, backs early-stage companies developing deep technologies grounded in fundamental research, from energy and medical devices to robotics and semiconductors. Support comes in two phases: Phase I awards of up to about 305,000 dollars for proof of concept over roughly 6 to 18 months, followed by Phase II awards of up to about 1.25 million dollars over about 24 months, with the potential for further supplements. The funding is non-dilutive, so founders keep their equity and intellectual property while gaining expert feedback and mentorship. Applicants move from a short project pitch to a full proposal, and eligibility centres on small, U.S.-based startups that are not majority owned by investment funds. For designers and technologists who frame sustainability challenges as opportunities, it is a concrete way to resource an innovation without giving up ownership. Programme figures and eligibility can change, so confirm the current details on the NSF site before applying.
