“Each year the National Science Foundation (NSF) invests millions into startup companies by way of its non-dilutive SBIR and STTR grants. Since 2012, NSF has made more than 2,500 awards to startups and small businesses. Since 2014, NSF’s awardees have had 70 exits and received $3.5 billion in venture investment. Two new contests have just been announced, each offering $225K in non-dilutive funding for early stage startups. The deadline for both is December 4th.”
After you get a SBIR grant, there is a Phase II SBIR grant available for $750,000.
