Slashy YC S25 Adds Native Attio Integration for Email to CRM
Below validation threshold — auto-passed without scoring
Slashy YC S25 launches native integration with Attio so send or receive email automatically creates deal, contact, and meeting notes in Attio. Power user Jake previously ran 40 plus cold outbound steps daily before the integration. After two weeks with Slashy, Jake stops opening Attio entirely for prospect replies. The integration closes the gap between email and CRM without manual entry. The post appears on May 19, 2026.
