Before you submit
Were you invited to submit a proposal?
NSF SBIR/STTR Phase I applicants are REQUIRED to submit a “Project Pitch” that outlines the project objectives, technical innovation and associated technical risks. Projects that seem to be a good fit will be officially INVITED to submit a full proposal.
Only invited SBIR/STTR proposals will be reviewed by NSF. To learn more about the Project Pitch, please visit How It Works.
Applying for Phase II?
Only NSF Phase I SBIR/STTR awardees are permitted to submit a Phase II proposal.
We encourage you to follow guidance from your program director about when and how to submit your Phase II proposal.
Preparing your proposal

The Phase I and Phase II SBIR/STTR Solicitations explain the content needed in your proposal. We also encourage you to join an upcoming webinar to help you prepare your proposal or to reach out to the relevant SBIR/STTR program director if you have questions about the proposal and review process.
