SBIR Phase II

SBIR Phase II is the primary R&D funding stage of the Small Business Innovation Research program, providing substantially larger awards than Phase I to carry out the full scope of research and development, including prototype development, testing, and commercialization planning, based on demonstrated Phase I feasibility.

What is SBIR Phase II?

Phase II is where the actual technology development happens. Building on the feasibility demonstrated in Phase I, Phase II awards fund the full R&D effort: refining the technology, building and testing prototypes, addressing manufacturing or scalability challenges, and developing a concrete commercialization plan. Phase II awards typically range from $750,000 to $2 million (agency-specific ceilings vary) and run for up to 24 months, though DoD Phase II awards can run up to 36 months with extensions.

Phase II applications must include a detailed technical proposal, a Phase I results summary demonstrating that the core technical approach is sound, a comprehensive commercialization plan, and a budget. The commercialization plan is weighted more heavily in Phase II evaluation than in Phase I, agencies want to see a credible path to non-SBIR revenue, whether through government procurement or private sector sales.

Many agencies offer Phase II Enhancement Programs or Supplemental Funding arrangements that allow Phase II awardees to access additional funds matched by private investment, or to extend Phase II work for additional transition activities. DoD's Phase II.5 concept allows continued development between formal Phase II completion and Phase III procurement.

Why SBIR Phase II matters for government contractors

Phase II is the most significant non-dilutive R&D funding event available to small businesses, providing millions of dollars to develop technologies that may transition into multi-year government contracts or private sector products. Phase II winners are also eligible for the SBIR Phase II matching investment programs that effectively double government R&D funding through private co-investment.

Example

Following a successful Phase I on advanced sensor fusion algorithms, a defense electronics company wins a $1.85 million DoD SBIR Phase II award for a 24-month development program. The team uses Phase II funds to hire three additional engineers, build and test hardware prototypes in a relevant environment, and conduct government-witnessed demonstrations. The Phase II concludes with a Technology Readiness Level (TRL) 6 system validated in a representative operational environment, and the program office initiates a Phase III procurement contract.

Frequently Asked Questions

Do all Phase I winners automatically qualify for Phase II?

No. Phase II is a separate competitive process. Completing Phase I makes the company eligible to submit a Phase II application, but Phase II awards are made based on Phase I results, updated technical merit, and commercialization strategy. Successful Phase I completion is a prerequisite, not a guarantee.

How is Phase II different from a Phase III contract?

Phase II uses SBIR-designated funds to support R&D and does not require the government to receive finished goods or services for operational use. Phase III is a procurement contract (not SBIR-funded) in which the government acquires the technology developed in Phase II for actual deployment. SBIR set-aside rules do not apply in Phase III.

Can a company receive multiple Phase II awards from different agencies for related technology?

Yes. Agencies do not share information about awards made to the same company for related technology. A company may pursue parallel Phase II awards from multiple agencies if the underlying research is distinct enough, though agencies have the right to review for duplication.

What is the "commercialization" requirement in Phase II?

Phase II applications must include a credible commercialization plan describing how the developed technology will generate revenue after the SBIR award ends, through government procurement (Phase III), private sector sales, or both. Weak commercialization plans are a leading reason otherwise strong Phase II applications are not funded.
