Call Eva
Your AI Voice Assistant
that actually works
Eva handles bookings, support, reminders, and escalations. 24/7, in natural-sounding conversation. No missed calls. No extra headcount.
The problem
Sound familiar?
Calls going unanswered after hours while revenue walks away?
Routine support calls eating margin on your most expensive staff?
Scaling the phone line means scaling payroll?
Short answer
Call Eva is an AI voice assistant for business phone lines. It handles inbound and outbound calls 24/7, covering support, bookings, reminders, and lead qualification. It connects to your CRM and calendar via API, and escalates to live agents with full context. Pilots go live in 4-8 weeks.
Why businesses are switching to Voice AI
Manual calls are costly and hard to scale. With Call Eva, every call is answered, follow-ups happen on time, and costs drop dramatically.
Before Call Eva
- We lose money when calls go unanswered.Nights and weekends are dead zones. Missed calls = lost bookings.
- Support costs are eating my margins."Can I reschedule?" and "Where's my order?" consume staff hours.
- Reminders slip and we deal with angry customers.Payments, check-ins, and confirmations get missed.
- Growth means hiring more people I can't afford.Scaling phones = scaling payroll.
After Call Eva
- Every call answered in seconds.24/7 coverage with a natural voice AI assistant.
- Routine calls handled for pennies.AI call automation frees staff for high-value issues.
- Follow-ups on time, every time.Automated reminders for invoices, appointments, and check-ins.
- Scale instantly, not headcount.Add lines/locations without adding salaries.
In practice
A hospitality client replaced a $60K/year night-shift role with Call Eva. Phone coverage stayed 24/7. Annual cost dropped to $6K.
Not every business sees that magnitude. Healthcare practices typically save 40-60%; B2B SaaS support saves 50-75%; high-touch consulting often stays flat because Eva escalates too often. Hospitality is the upper bound. See how we build AI voice agents end-to-end.
Where Eva isn't the right fit. Eva isn't a replacement for complex multi-step legal or medical decisions, regulatory verification calls (credit card auth, ID verification), or businesses with under ~100 inbound calls a month. At that volume the savings don't outweigh the setup, and you're better off with a human answering service or a structured voicemail flow.
