SBIR Grants from National Institutes of Health (NIH)
Researched by the BidStride Research Team
Agency overview
NIH is the second-largest SBIR funder, directing more than $1.1 billion per year into biomedical and health technology innovation. NIH SBIR awards support drug discovery, medical devices, diagnostics, digital health tools, and health IT. Unlike DoD, NIH topics are investigator-initiated — companies propose their own research objectives within NIH's broad health mission rather than responding to specific agency-defined topics. NIH runs three grant cycles per year (January, April, and September submission dates).
Award details
Phase 1 — Feasibility
Typical Award Amount
$300,000
Duration
6 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
$2,000,000
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 Institutes of Health 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
3 cycles per year — January, April, and September submission windows
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 NIH solicitations
Visit https://seed.nih.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.

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
NIH 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 NIH SBIR
No. NIH SBIR is largely investigator-initiated. You propose your own health-related research question and demonstrate its commercial potential. NIH does publish some targeted 'omnibus' solicitations, but most awards come from companies proposing their own biomedical innovation.
The Specific Aims page is a one-page summary of your research objectives, hypotheses, and expected outcomes. It is the first thing reviewers read and carries enormous weight. Most successful NIH SBIR applicants get their Specific Aims reviewed by a program officer before submission.
Yes. NIH SBIR is specifically designed for early-stage companies. You do not need prior NIH funding, but you do need to demonstrate that your company qualifies as a small business and that the PI spends at least 51% of their time on the project.
NIH SBIR Phase 1 success rates have historically run between 15–25% depending on the institute and fiscal year. Phase 2 success rates for applicants who already hold a Phase 1 award are somewhat higher, typically 30–45%.
