If you only remember one thing: SBIR.gov is the official archive; SBIR Signal is the capture workbench. You often need both.
Practitioners say “award search” for three different jobs:
SBIR.gov is excellent at the first job when you need the deepest historical record. It is slower for the second and third. That is the gap SBIR Signal fills with a modern SBIR award search, winner leaderboard, and capability match.
| Need | Prefer |
|---|---|
| Canonical historical citation | SBIR.gov |
| Fast filter by tech domain / agency / phase | SBIR Signal |
| Firm competitive profile + similar firms | SBIR Signal |
| Open topics + deadlines in one feed | SBIR Signal |
| AI match / Go-No-Go decision pack | SBIR Signal |

That workflow keeps you out of “PDF archaeology” until the moment a proposal actually needs the system of record.
