During my solicitation search, I have encountered SBIR solicitations as well as SBIR Pre-Solicitation announcements. What is a pre-solicitation announcement?
SBIR solicitations are specific Requests for Proposals, released by award-granting federal agencies, which can result in Phase I SBIR funding agreements. SBIR Pre-Solicitation announcements, released by SBA, contain pertinent information about SBIR solicitations that will soon be released by the participating federal agencies.
