Every SMB sales rep has been there: great demo, prospect is excited, and then... life happens. The follow-up email gets delayed by a day, then two, then the deal goes cold. Enterprise teams have Gong and Salesloft to automate this, but at $100k+/year, SMBs are left doing it manually or not at all. The AI Sales Follow-Up Agent changes this — within an hour of your call ending, you have a personalized email ready to send with a tailored proposal attached.
📊 Market Evidence
The Market Gap
Enterprise has full solutions. SMBs have transcription tools (Fireflies, Otter) but nothing that turns transcript into action. The 1-hour post-demo window is when deals are won or lost.
