When is DoD SBIR/STTR the right fit?

Best when you have a defense or dual-use customer path Topics are component-specific; transition matters early DSIP process and operational framing are central

When is NSF SBIR/STTR the right fit?

Best for deep-tech with high technical risk and company-building Customer discovery and commercialization science matter Not a substitute for DoD end-user narratives

When is NIH SBIR/STTR the right fit?

Best for biomedical and health product paths Institute fit and clinical/regulatory realism are decisive Distinct from BARDA countermeasure procurement logic

When is DOE SBIR/STTR the right fit?

Best for energy-mission topics from DOE program offices Topic alignment to DOE FOA language is required Commercialization should fit energy markets and DOE missions

SBIR / STTR Agency Fit Guide: DoD, NSF, NIH, or DOE?

Choose the right SBIR/STTR agency track before writing Phase I—review culture and transition expectations differ sharply.

Velawolf recommendation

Start with the multi-agency SBIR hub for triage, then pursue the agency-specific guide. Velawolf runs fit assessments before Phase I spend.
