What this program funds
NSF's SBIR/STTR program — branded America's Seed Fund — funds early-stage deep-technology R&D inside small businesses: work with genuine technical risk and broad commercial potential, before private capital will touch it. Phase I is a feasibility study; Phase II funds the development that follows a successful Phase I. Unlike most NSF programs, the money is non-dilutive funding to a company, the proposal is judged heavily on commercial impact, and there are no pre-set topic areas — nearly any technology field can fit.
Eligibility in plain English
- The applicant is a U.S.-based, majority U.S.-owned small business (under 500 employees) — often formed around university research, but the company, not the university, holds the award.
- The PI does not need a PhD or faculty title, but must be primarily employed by the company (more than half time) by the time of award — the rule that most often forces academic founders to choose a company-side lead.
- STTR adds a required formal partnership with a nonprofit research institution, with minimum shares of the work on each side of the partnership.
- Before a full proposal, you must submit a short Project Pitch and receive an invitation.
- Ownership, employment, and subcontracting percentages are exact and audited — confirm with your sponsored-programs office (and the company's counsel) and the current solicitation.
What you'll need to submit
- Project Pitch (short web form) — the technology, the innovation, the technical risks, and the market; invitation required to proceed.
- Full proposal, including the technical R&D plan and objectives for the phase.
- Commercialization narrative — market, customers, competition, and the path to revenue.
- Budget and Budget Justification, plus subaward documentation for any research-institution partner (required for STTR).
- Company and team information, registrations (e.g., SAM), and any letters from potential customers or partners the solicitation allows.
Tips for this mechanism
- Treat the Project Pitch as a real gate, not paperwork. It exists to give you a fast yes-or-no on fit before you write 20 pages. A decline at the pitch stage usually means the framing — too incremental, or no technical risk — not the technology.
- Lead with the unresolved technical question. NSF explicitly funds what it calls high-risk R&D; a proposal that reads like product engineering with a known outcome will lose to one organized around a feasibility question that Phase I will answer.
- Academic founders: resolve the employment and COI questions early. The PI-primarily-employed rule, university conflict-of-interest policies, and IP licensing between the university and the company each take months. Sort them before the proposal, not after the award notice.
- Ground the commercial story in named evidence. Letters from potential customers, pilot commitments, or discovery-interview counts are worth more than market-size boilerplate — reviewers see the same "billion-dollar TAM" slide in every proposal.
