SBIR

In detail

Each participating agency runs its own solicitations, on its own schedule, with its own award sizes and its own topic lists. There is no single SBIR competition, which is why "the SBIR deadline" is not a thing that exists.

Eligibility is unusually strict and it is about ownership rather than activity: a small business, majority-owned by US individuals or by other eligible small businesses, with the work performed principally in the United States. Venture ownership rules vary by agency.

Against STTR

STTR requires a formal partnership with a research institution and sets a minimum share of the work for each side. SBIR does not require a partner at all. They are separate appropriations with separate solicitations, and an eligibility list naming one has not named the other — which is why we map source eligibility values verbatim rather than folding near neighbours together.

How GrantTrove stores it

• `elig_entity_types` records the applicant classes the notice names; a business-eligible notice appears under the business applicant class rather than under a research label.
• The amount columns keep phase awards where the notice put them: `amount_max` is a per-award ceiling, and `amount_total_pool` is a programme total that no applicant receives.
