About Signals
Summary
Signals builds an AI customer engagement agent for direct-to-consumer brands, communicating with shoppers over iMessage and RCS across the full purchase lifecycle. It answers pre-purchase product questions, handles order and delivery issues, and prompts repeat purchases, replacing the work a skilled in-store associate would otherwise do. The product is designed to reduce returns, deflect support tickets, and drive incremental repeat revenue without requiring discounts.
Business model
Fee per conversation or per engagement over iMessage and RCS
Go-to-market
DTC e-commerce brands are the buyers; they get started through a booked demo and onboarding to the iMessage channel.
