Phase I is the jumping off point for most small businesses and research institutions working with the program. It is known as the “idea generation” phase, during which small businesses (and their research institution partners in STTR) establish the scientific, technical, commercial merit and feasibility of the proposed innovation. You can discover the types of technologies NASA is looking for by reading through the most recent Phase I solicitations.
This year, the NASA SBIR/STTR program is undergoing a change from our traditional solicitation cycle to a Broad Agency Announcement, or BAA. Click the link below to learn more.
NASA selected 299 small business teams to develop new technologies to address agency priorities. The new awards from NASA’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) program invest in a varied portfolio of American small businesses and research institutions to support NASA’s future missions. About 32% of the companies selected are first-time NASA SBIR/STTR recipients. Each proposal team will receive $150,000 to establish the merit and feasibility of their innovations for a total agency investment of $44.85 million. The complete list of this year’s SBIR and STTR awardees are available below (2025 NASA SBIR Phase I Selections & 2025 NASA STTR Phase I Selections).
