Who SBIR is best for
SBIR is a fit for teams with a defensible technical innovation, a clear agency need, and the ability to write a research plan. It is usually not a fit for ordinary working capital or local-service businesses.
SBIR vs. other startup grants
Unlike many local small-business grants, SBIR is research-focused and competitive nationwide. It can be non-dilutive, but applications require technical detail, budgets, milestones, and agency alignment.
