The STTR program supports collaborative projects focused on technological innovation with commercialization potential. EVAMAX is here to assist with your application to maximize its achievability.


The Small Business Technology Transfer (STTR) program aims to encourage US small businesses to engage in research and development (R&D) with potential for commercialization. The STTR program provides award-based funding as incentive for technological innovation.

The STTR program requires the small business to formally collaborate with a non-profit research
institution in Phase I and Phase II. The main objective of the STTR program is to bridge the gap between performance of basic science and commercialization of resulting innovations.

How It Works

The STTR program is provided by the U.S. Small Business Administration (SBA). The SBA allocates funding for the STTR program to each of the 5 participating agencies listed below who then provide awardee small businesses with either a grant or contract for funding.

DoD - Department of Defense

DOE - Department of Energy

HHS -Department of Health and Human Services

NASA - National Aeronautics and Space Administration

NSF - National Science Foundation

The Three phases

The SBIR program consists of three phases.

Phase I

During phase I, the technological merit, feasibility, and commercialization potential of the proposed R&D will be established. The quality of performance of the small business will also be determined to evaluate the possibility of stage II funding.
Funding: $50,000 – $250,000 for 1 year

Phase II

Typically, only phase I awardees are eligible for phase II. During phase II, R&D efforts started in phase I will be continued and awardees are assessed based on their outcomes in phase I, technological merit and commercialization potential from the phase II project.
Funding: $750,000 for 2 years

Phase III

In phase III the small businesses’ focus is on commercializing outcomes achieved through phases I & II.
Funding: The STTR program does not fund phase III
