Mozart unitThe computer your team of agents lives on.
You ask on WhatsApp, the way you'd text a colleague. The coordinator assigns, the workers deliver and reception replies. What matters reaches your phone, and one yes sends it out.
Write to your team the way you already do, at any hour and from anywhere.
The coordinator assigns the task and wakes the worker it needs. In your office, the proposal builds itself.
The proposal lands on your WhatsApp. You reply yes and it goes to your client, with the follow-up already booked.
Message our demo number. Mozart prepares a sample proposal and delivers it as a PDF.
Every role has its craft and its rules. Together they carry the work from the first message to delivery.

Up to 8 agents per company. Workers switch on when there's a task and rest when it's done.
Every five minutes Mozart takes its own pulse. If an agent goes down, it brings it back.
A heavy task arrives and Mozart wakes a worker. The work gets done, and the worker goes back to sleep.
Every version of Mozart is born with what we learned running the previous ones.
Anything that commits your company waits for your yes: final quotes, discounts, payments and posts.
Your team's rules are sealed, and no conversation can change them.

Platform agents assist one person and keep their memory in the platform's cloud. Mozart is your company's complete team: it serves your clients, works in your systems and lives on a computer in your office, and Simphony sets it up with you and supports it.
Mozart is model-agnostic: each task runs on the language model that solves it best, through a commercial API. AI usage is included in your monthly fee, within your plan's message volume.
Your team's memory, your documents, your credentials and your WhatsApp session live on the Mozart unit in your office, and Simphony keeps no copy on any server of its own. To think, each agent queries a language model through a commercial API, with only what the task needs and over an encrypted channel. At setup we hand you the clause for your privacy notice.
Reception replies with fixed rules and short answers. Anything that commits your company, such as final quotes, discounts, payments and posts, waits for your yes. Before you pay, you watch Mozart work on a case from your own company in the demo.
Pulse checks the team every five minutes and brings back any agent that went down. Your admin number gets the alert and Simphony provides remote support.
WhatsApp can block numbers that automate messages at high volume. That's why Mozart runs at moderate volume with per-contact rules, and for high volume we evaluate the official WhatsApp Business API with you. The contract covers it in detail.
The Mozart unit switched on at all times, with a good internet connection, and your company's WhatsApp. We take care of everything else.
We ship the Mozart unit to your office, in any country, and set it up with you remotely. We connect your WhatsApp, configure your admin number, your plan's rules and the privacy step, and close with a three-task test: Mozart reads a PDF, transcribes a voice note and replies on WhatsApp.
You start with a 30-day pilot and three metrics signed before installation: messages resolved without you, time to first response and hours returned per week. If they're not met, you walk away with no penalty and we remove everything.
You talk to your team on WhatsApp, the way you'd talk to a person. We handle the technical side.
