SBIR Grants from National Science Foundation (NSF)
Researched by the BidStride Research Team
Agency overview
NSF SBIR — also branded as 'America's Seed Fund' — focuses on deep technology and translational research. NSF funds companies commercializing fundamental science in areas like advanced materials, robotics, semiconductors, clean energy, and software. NSF is unique in that it funds the riskiest, most technically novel ideas with no government application requirement — the only output is commercial success. Applications are accepted on a rolling basis through the NSF SBIR/STTR program.
Award details
Phase 1 — Feasibility
Typical Award Amount
$275,000
Duration
6–12 months
Phase 1 establishes the technical merit and feasibility of the proposed R&D. The deliverable is a feasibility report and prototype demonstration where applicable.
Phase 2 — Full R&D
Typical Award Amount
$1,000,000
Duration
24 months
Phase 2 funds the primary R&D effort to develop the technology to a commercializable or deployable state. Only Phase 1 awardees (or those who meet equivalent requirements) may apply.
Research topic areas
National Science Foundation SBIR solicitations consistently address the following research areas. Specific topics vary by solicitation — check the current open solicitation for exact topic descriptions and technical points of contact.
Solicitation cycle
Rolling deadlines — 3–4 windows per year
Solicitation windows open and close on a defined schedule. Applications submitted after the close date are not accepted. Set a calendar reminder at least 6 weeks before the close date — a well-written SBIR application typically takes 60–90 hours of preparation for a first-time applicant.

Register in SAM.gov
All SBIR applicants must have an active SAM.gov registration. Registration can take 1–3 weeks. Apply early — the government cannot issue payment on an SBIR award without an active SAM.gov registration.

Review open NSF solicitations
Visit https://seedfund.nsf.gov/ to see currently open solicitations. Read topic descriptions carefully — each topic has a Technical Point of Contact (TPOC) you can contact with technical questions before submitting.
- 4
Contact the TPOC
Each topic lists a Technical Point of Contact. Email them with a 2-3 sentence summary of your approach before writing your full proposal. TPOCs can tell you whether your company's approach aligns with what the agency is looking for — this step alone doubles your success rate.

Submit through SBIR.gov or the agency portal
NSF SBIR applications are submitted through the agency's designated portal. Most DoD applications go through SBIR.gov. NIH uses ASSIST (grants.nih.gov). NSF uses Research.gov. Check the solicitation for the correct submission system.
Frequently asked questions about NSF SBIR
NSF backs the riskiest deep tech bets. There is no specific government customer requirement — NSF funds innovation that may eventually become a commercial product in any market. The agency is known for funding technologies 10–15 years from commercialization that no private investor would touch.
NSF does not require customer letters at Phase 1, but they strongly emphasize commercialization potential. Phase 2 applications require a commercialization plan and evidence of market validation, including customer discovery interviews.
Yes. NSF SBIR is ideal for pre-revenue companies. The program does not require revenue history or prior awards. Many successful applicants are university spinouts or first-time founders with a novel technology thesis.
NSF SBIR Phase I applications are submitted through Research.gov. The core documents include a Project Description (15 pages), a Commercialization Plan, team bios, and budget justification. NSF program officers are accessible and encourage pre-submission consultations.
