The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are the U.S. government’s primary engines for funding early-stage innovation. These competitive grants help small businesses and startups develop high-impact technologies with strong commercialization potential—without giving up equity or control. Together, they connect entrepreneurs, researchers, and federal agencies to accelerate breakthroughs from lab to market, fueling both economic growth and national competitiveness
🧠 What It Is
SBIR and STTR are federal programs that fund small businesses to develop innovative technologies.
They bridge the gap between idea and commercialization — turning research into real-world impact.

💰 Why It Matters
Together, SBIR/STTR represent over $4 billion annually in non-dilutive R&D funding.
That’s money you don’t have to pay back or give up equity for.
🧩 The Difference
Program | Key Feature |
SBIR | Small businesses perform R&D independently. |
STTR | Requires a formal partnership with a U.S. research institution (e.g., university, national lab). |
🪜 The 3 Phases
Phase I – Proof of Concept
Feasibility study, usually $50K–$275K for ~6–12 months.Phase II – Prototype Development
R&D to develop a working product, typically $750K–$2.1M over 2 years.Phase III – Commercialization
No direct SBIR/STTR funding. Focus on private investment or government acquisition.
