US Offers Startups Up to $1.55M Through Relaunched NSF Seed Fund

The U.S. government is offering startups up to $1.55 million in non-dilutive funding — and taking zero equity in return. Through the National Science Foundation’s relaunched America’s Seed Fund, founders developing high-risk technologies can secure federal R&D money while keeping full ownership of their companies and intellectual property.

What the NSF Seed Fund Offers

The money comes through the NSF’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, branded America’s Seed Fund. The agency restarted the programs in May with $250 million for U.S. startups and small businesses developing high-risk technologies with commercial potential, following a government-wide statutory lapse that ended on September 30, 2025, and a subsequent five-year reauthorization by Congress.

For founders, the appeal is straightforward: this is R&D funding, not venture capital. Award recipients keep full ownership of their companies and their intellectual property.

The Three Funding Tracks

The program runs on three tracks, all confirmed under the current NSF solicitation:

The headline $1.55 million Fast-Track route combines up to $400,000 for the Phase I portion with up to $1.155 million for Phase II. It is reserved for a narrower group of companies that need qualifying NSF-funded research from the past five years, recent formal customer-discovery training such as I-Corps, a complete team, and an invitation from NSF after submitting a Fast-Track Project Pitch.

Who Qualifies for NSF Seed Fund Startup Funding

The program is aimed at U.S.-based small businesses with fewer than 500 employees. At least 51 percent of the business must be owned and controlled by U.S. citizens or permanent residents, and the funded R&D must be performed in the United States. The company’s principal investigator must spend the majority of their working time employed by the startup during the funded project.

Startups without a Fast-Track background can still pursue the regular Phase I path, which can lead into Phase II funding later. Competition is real: the NSF expects roughly 180 SBIR Phase I awards and 50 STTR Phase I awards per year, with Fast-Track much smaller at about 15 SBIR and three STTR awards annually.

How to Apply Before the Deadline

The process starts with a short Project Pitch instead of a full grant proposal. Founders submit a brief overview describing the technology, the technical risk involved, the problem it addresses, and its potential commercial or societal impact. The NSF reviews the pitch and invites qualifying companies to submit a full proposal through Research.gov.

Pitch reviews typically take about one to two months, with funding decisions arriving about six months after a full proposal is submitted. The next full-proposal deadline is November 4, 2026, at 5 p.m. in the submitting organization’s local time, with further deadlines scheduled for March 4 and July 7, 2027.

For a technical founder weighing venture capital against limited runway, the trade-off is unusual: federal money to prove the technology, with the cap table left untouched. Danish founders watching global funding trends can compare with recent local rounds, such as the Copenhagen founders buying back AI startup Good Tape in a €600k round and Armadin’s $255.5 million Series B.
