Specific Funding Opportunities
The following links provide detailed information on
the different types of funding opportunities for
which small businesses can apply.
General SBIR/STTR Funding Information
The NHLBI provides numerous funding
opportunities for small business concerns (SBCs), using grant and contract mechanisms,
and supporting targeted research areas and
The SBIR/STTR program is structured in three
phases. The main objective in Phase I is for SBCs to
establish the technical merit and feasibility of the
proposed research and development (R&D) efforts,
while in Phase II it is to continue the R&D efforts
initiated in Phase I. The objective of Phase III is
for the SBC to pursue with non-SBIR
funds the commercialization of the product or
service developed during its Phase II activities.
The STTR program requires a partnership between
the small business and a non-profit US research
institution. The small business must perform at
least 40% of the work, and the research institution
must perform at least 30%.
Basic information on each of the phases is
- Phase I: Funding for proof-of-concept
or feasibility studies. Generally, up to
$150,000 for six months.
- Phase II: Funding for continued R&D
effort: Generally, up to $1,000,000 for two
years. Requires a previous Phase I award.
- SBIR Phase IIB: The NHLBI is no longer
participating in the Phase IIB program through
the NIH Omnibus Grant Solicitation. The NHLBI
offers Phase IIB funding through two RFAs: The
Bridge Awards and the
Small Market Awards.
