You are the receptionist at Clínica Norte. You answer in Mexican Spanish,
warm and to the point. Your job is to book, confirm or move appointments.

1. Greet, ask for the caller's name and the reason for the visit.
2. Offer the first open slot with the right specialist.
3. If the patient hesitates, offer two more options, never a long list.
4. Confirm date, time and branch before hanging up.

If they ask about prices, use the knowledge base. If you don't know
something, say so and offer a callback from a human.

Platform

Build, test, deploy and measure
from one place

Use cases

One engine, trained on your process

The same agent, configured with the questions, objections and calendar of your industry.

Real estate

Portal leads arrive at any hour and the first agent to answer gets the visit.

Education

The prospect enrolls with whoever answers first, not with whoever has the better program.

Clinics

Calls from new patients get lost while the front desk is busy with the ones already there.

Professional firms

The prospect comes by referral, waits days for an answer and consults someone else in the meantime.

Insurance

High-intent leads that need immediate, persistent follow-up, more than the team can dial.

Franchises

Several locations, several lead channels and no single follow-up process.

How it works

Live in three steps

Step 01
Create the agent
Sign up, describe your business and the Builder drafts the prompt, picks a voice and links your website as knowledge.
Step 02
Test it from the browser
Talk to it, adjust the prompt and the voice settings, and run it again until it sounds like your team.
Step 03
Publish and connect
Assign a number, connect your CRM and calendar, and every call lands where your team already works.

For developers

Everything the agent does, also from code

A REST API with OpenAPI 3.1, signed webhooks, tools that call your backend mid-call and a voice engine where you pick each provider. Same capabilities as the dashboard, from your stack.

Languages

Speaks natively in 32 languages

Not a translation layered over an English voice: a native voice, with the accent and intonation of the language. Spanish first, and the same engine across all 32.

FAQ

Frequently asked questions

What can a Ryvo agent do?

It answers and places phone calls with a natural voice, follows the prompt you give it, answers from your knowledge base, books on your calendar, calls your tools mid-conversation and hands off to a person when the caller asks. Every call ends with a transcript, a recording and the fields you asked it to extract.

Which languages and voices are available?

Spanish is the first language: voices, speech recognition and support are built for it. The same engine works in 32 languages, and you can pick the voice per agent from the ElevenLabs and Cartesia catalogs.

How long does it take to go live?

Minutes. Sign up, describe your business and the Builder drafts the agent. You can talk to it from the browser before you connect a number or a CRM.

Can I pick the model and bring my own keys?

Yes. You choose the speech-to-text, language and text-to-speech provider per agent, with a fallback for each. Bring-your-own-key is available on the Scale plan and on enterprise agreements.

What happens when the caller asks for a person?

The agent takes the caller's name and number, tells them the team will call back, and logs the request. It never invents information it doesn't have.

How is it priced?

By the minute, billed per second, with credits. Pay as you go has no monthly fee; Starter, Pro and Scale include minutes at a lower per-minute rate and unlock more agents, users and concurrent calls.
