No small business should lose a customer to voicemail
Tethyr is an AI-powered phone assistant that answers every call, books appointments, and captures leads — so you can focus on running your business instead of being tied to the phone.
Why we built Tethyr
We kept hearing the same story from small business owners: “I know I'm missing calls, but I can't afford a full-time assistant, and answering services feel impersonal.”
The math is brutal. Studies show that 80% of callers who reach voicemail don't leave a message — they just call the next business. For a dentist or HVAC company, that's thousands in lost revenue every month from calls that come in during lunch, after hours, or when the front desk is already on the phone.
We built Tethyr to solve this. Using natural-sounding AI that understands your business, Tethyr picks up every call within seconds — nights, weekends, holidays. It answers common questions, books appointments directly on your calendar, and sends you a summary of every conversation. Setup takes 15 minutes, not weeks.
What drives us
Every Call Matters
A missed call is a missed customer. We built Tethyr because small businesses deserve the same always-on availability that enterprises take for granted.
Simple by Default
AI should feel effortless. Tethyr works out of the box in 15 minutes — no scripts to write, no complex IVR trees, no IT department required.
Built for Small Business
We focus on the businesses that power local communities — dental offices, HVAC companies, law firms, salons, and more. Every feature is designed for your workflow.
Always Improving
Our AI learns from every interaction. The longer Tethyr works for you, the better it gets at handling your specific callers and booking preferences.
