The problem

Every missed call is revenue walking out the door.

30% of inbound calls go unanswered. Most happen at lunch, after hours, or on weekends — exactly when prospects are ready to spend money.

By the time you call back, they've already booked elsewhere. Nexel makes sure that doesn't happen.

From the people on the other line.

★★★★★

We were missing 4–5 calls a day after hours. Nexel's agent now books them while we sleep. Paid for itself in two weeks.

I expected a chatbot. I got a full-time receptionist that never takes a sick day. My team finally focuses on patients in the office.

★★★★★

The voice quality is uncanny. Our patients have no idea they're talking to AI — and our booking rate is up 38% in two months.

FAQ

Questions, answered.

A chatbot reads scripts. A Nexel agent has real conversations — picks up the phone, speaks naturally, handles interruptions, asks follow-ups, books appointments. Built on the latest voice models, tuned specifically for your industry.
Most don't. The voice quality is near-photorealistic — natural pacing, breathing, filler words, accent matching. We're transparent if asked directly. You can also have the agent identify itself at the start of every call if your industry requires disclosure.
Most clients are live in 7–10 business days. First three days are discovery and scripting, next four are engineering and testing, final days are integration with your phone system and calendar. We don't launch until your agent passes our 50+ edge case test suite.
Out of the box: Google Calendar, HubSpot, GoHighLevel, Calendly, Twilio, WhatsApp, SMS — plus 50+ others via Zapier. Custom integrations for industry-specific software (dental PMS, legal CRMs, field service tools) on Growth and Scale plans.
The agent recognizes escalation triggers — emergencies, complaints, complex medical or legal questions — and warm-transfers the caller to your team. You stay in control of when and how human handoff happens.
No contracts and no setup fees on Starter and Growth — month-to-month. Scale plans include a discounted annual rate with a dedicated success manager. Cancel anytime.
