Round by round
| GUMSHOE | APOLLO | |
|---|---|---|
| CORE JOB | Deep company research + verdicts | Contact database + sequences |
| DATA FRESHNESS | Live navigation + web signals, dated | Static records, some stale |
| WHAT COMES BACK | Typed JSON: fit, confidence, cited facts | Contact rows to email |
| ACCURACY | Every claim tied to a source you can check | 65 to 80% email accuracy in tests |
| SIGNAL DETECTION | Hiring, funding, tech, competitor mentions | Basic intent add-ons |
PICK GUMSHOE IF
Independent tests put Apollo's real email accuracy at 65 to 80% (vs 91% claimed), with 32 to 38% bounce rates on exported lists. And because the free tier is so generous, the same contacts get hammered: your prospect gets their fifteenth Apollo cold email this week.
PICK APOLLO IF
If you need raw contact volume and a cheap entry to build big lists fast, Apollo covers it. It's a database, not a research agent.
