Two ways to pay
SBIR Phase I Full Proposal
The post-invitation proposal you submit to NSF after they invite you. Generated at maximum quality with hard character-limit enforcement and anti-fabrication guardrails. Pay $0 upfront with a 10% success fee on award (or $2,500 upfront).
How the funnel works: Start with the $250 Pre-Proposal — that's the entry point. Completing it unlocks the $0-upfront, 10%-on-award path below. The $2,500 upfront option needs no Pre-Proposal. Either way, your NSF invitation letter is required before full-proposal work begins.
What you get (both options)
- ✓ Maximum critique-refine iterations
- ✓ Every NSF Full Proposal section
- ✓ Hard character limits enforced in code
- ✓ Anti-fabrication guarantee
- ✓ Word document download
- ✓ Reviewer-criteria fit check before submission
