## Positioning

- **Category:** AI BDR / AI SDR / autonomous outbound.
- **Audience:** Early-stage and SMB B2B tech founders and sales leaders who need pipeline now but don't want a bloated BDR team.
- **Philosophy:** We don't replace salespeople. We get them back to selling. Most reps today are stuck behind a stack of 100 tools doing research, list-building, copywriting, follow-ups, and CRM hygiene — work they weren't hired for. Rook handles that boring, mechanical outbound autonomously so reps stay in front of customers.
- **Differentiators:** Deep agentic research across billions of signals (going beyond Apollo), live buyer profile building, outbound copy trained on 100,000+ winning sales messages, meetings booked directly in reps' calendars.
- **Integrations:** HubSpot, Salesforce, Gmail, Outlook, Lemlist, Gong, Slack.
- **Category peers:** Artisan, 11x, Sera, Alta, Salesforge.
- **Alternative to:** Apollo (for outbound), traditional human SDR/BDR hiring at sub-$4M ARR.
- **Pointedly NOT:** a "replace your BDRs with AI" product.
