SBIR and STTR grants
SBIR and STTR are the United States' seed fund for small companies with a technical idea a federal agency wants to see built. Each agency runs its own calls under the same rules, so the openings are scattered across a dozen sites. This page gathers every one the catalogue tracks, open calls first, from the health, science, space, energy and defence agencies down to the state programmes that top up a federal award.
