Funding Opportunities

Topics and solicitations are known by many names including Request for Proposals (RFP), Funding Opportunity Announcement (FOA), Broad Agency Announcement (BAA), or simply Topic/Solicitation. No matter what it's called, they outline specific rules and guidance on how to prepare a response, also called an application or a proposal.

Funding Planner

Participating Agencies post SBIR/STTR funding opportunities on a regular periodic basis throughout the year. Some agencies have multiple solicitations throughout the year, while others may only have one solicitation release each year. Once you identify a relevant agency to target, learn more about that specific agency's process.
