The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs set aside part of federal research budgets for small companies. Agencies award them in phases: Phase I tests whether an idea is feasible, Phase II funds development, and Phase III is follow-on work paid for outside the set-aside. STTR awards also require a research institution as a partner.
Every figure on this page is taken from the award's own federal record, linked beside it, as it stood when the page was built: the recipient, its address, the awarding agency and office, the amount obligated so far, the dates and the description. Phase and program are shown as the award's own description states them. The amount can grow later if the agency adds funding to the same award.
