Comparing Zaion and Revox
The Zaion alternative built for outbound calling.
Zaion presents itself as "the French specialist in agentic AI for customer relations", with AI agents, real-time agent assist and conversation analytics. Revox does something else: voice agents that place your outbound calls, call your leads back and book your appointments. You build your agent in 5 minutes, it starts calling the next day, at 50 cents per prospect worked.
Where you are today
You are evaluating Zaion, but your problem is a sales problem.
Customer relations platforms handle requests that come to you. You have leads waiting for someone to call them.
You look for a Zaion review and find customer service projects
Zaion talks about automating customer interactions and assisting advisors: onboarding, access and identity, claims, reimbursements. These are requests coming towards you. Your need runs the other way: forms filled in yesterday, quotes with no answer, a contact base nobody calls back.
Pricing comes at the end of the journey
On most enterprise platforms, the price is built in a meeting, after the project has been scoped. You need an order of magnitude before talking to your management, and a way to test for a month before committing.
The real issue is the delay between the signal and the call
Over 90 days of Revox data, a lead called within 48 hours of raising a hand yields 70% positive conversations. A purchased cold list, 14%. Your leads do not lack volume, they lack a fast call, and no sales team has time to call everyone back the same day.
What Revox does
An outbound agent you set up yourself, with no project.
No scoping, no prior integration: a contact list, a goal, and the agent calls.
You describe what the agent must obtain, it is ready in 5 minutes
An appointment in the sales rep's calendar, a resumed sign-up, an answer on a quote: you write it in one sentence, an assistant drafts the agent's script. You pick a voice among more than 30. No limit on the number of agents.
You upload your list, the agent calls within 24 hours, up to 5 attempts
A contact file is enough to start, HubSpot and Zoho connect whenever you want. The agent recognises voicemail and tries again later, stops as soon as the person is reached or asks it to, and transfers to a human on the number of your choice.
You review every call, the team answers within 3 hours
Every conversation is recorded and transcribed in your workspace. One person on the team, six in total, follows your account and answers within 3 hours. Setup and support are included at no charge.

Before you choose
Zaion or Revox: the questions you are asking.
Factual answers, so you know who each one is for.
For outbound calling, yes. Zaion describes itself as the French specialist in agentic AI for customer relations: automating customer interactions, assisting advisors in real time. Revox is a voice agent that places your outbound calls across the whole sales cycle: inbound lead callback, follow-up, qualification, appointment booking, database reactivation, after-sales. If your goal is to answer your customers, look at Zaion. If your goal is to call your prospects faster, look at Revox.
For Zaion, we found no public pricing on its site at the time of writing, you have to contact them. Revox publishes its own: €500 excluding VAT per month for 1,000 prospects worked, or 50 cents per prospect. A prospect worked includes up to 5 call attempts, the conversation, and the answer if the prospect calls back. Setup included, first month with no commitment, then six months minimum.
For Zaion, their site publishes testimonials and customer cases. For Revox, we would rather let you listen: the getrevox.com homepage plays real calls placed by our agents, from cold calls to follow-ups, across several sectors. That is what the first month with no commitment is for: you judge on your own calls, not on ours.
In one case only: when a prospect the agent has called rings the number back, the agent answers, 24/7. On a rental matching platform, 15.8% of people called rang back on their own. Revox is not a customer service tool for your everyday inbound calls. The heart of the product is the call you place.
In France and in Europe. Your lists, recordings and transcripts are isolated in your account, never resold, never used to train a model. You set the retention period and delete whenever you want. The agent says it is an AI when asked, as French law has required since 2 August 2026.
The direction of the call. Revox is built for outbound: calling back, following up, qualifying, booking meetings. That is the first thing to look at when comparing two voice solutions.
500 € excluding tax per month for 1,000 prospects worked, that is 50 cents per prospect, setup included. The price is public because no project scoping is needed to start.
Five minutes to create the agent, twenty-four hours to launch a campaign with your list. No prior integration, no specification document.
Never lose
another prospect.
Your leads called back, followed up, and qualified by AI. Your sales team focuses on one thing: closing.
