For latest version: please go to https://academicentrepreneurship.pubpub.org/pub/department-of-defense/release/1 Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants are a government funding program offered by eleven federal departments and awarded to small businesses looking to develop and bring a product to market. The Department of Defense (DoD) and its twelve agencies award more than half of all SBIR/STTR grants; they solicit proposals for designated projects biannually. Broad Agency Announcements (BAAs) are another source of funding that can widen the scope of possible proposals but is not limited to small businesses. BAAs can be awarded to small and large businesses as well as academic institutions and nonprofits. Small business grants are vital in many research startups, and have shown themselves to be helpful to both the DoD (which may often purchase the technology) and the American workforce.
