The inbox that answers itself.
A privacy-first agentic inbox for customer care.
Great customer care is expensive to staff and never sleeps.

One agent takes months — and thousands — to train A new support hire costs $10K–$20K and 60–90 days of ramp before they're fully productive. · McKinsey / industry
-
…and you're re-hiring before they're good Support attrition runs 30–45% a year, with 70% of it in the first 90 days — so you pay that ramp cost over and over. · JustCall
-
Support can't scale with growth Double your customers and you double the queue. Headcount — and cost — climbs linearly while your margins shrink.
-
24/7 coverage is out of reach for an SMB Staffing a single seat around the clock takes 4–5 agents across shifts, weekends, and holidays. Nights and spikes still go unanswered.
An inbox that works itself — with you in control.
