Voice agents at scale.Low latency at high concurrency, from day one.
Turn the volume up and nothing changes. Synapse scales with you, and every call runs isolated — so one failure never becomes an outage.
Built on the providers your team already trusts
Every company will need its own voice.
Not a chatbot with a phone number bolted on. A voice that picks up in under a second, holds a real conversation, and does the work at the end of it — on your numbers, with your data, at whatever volume Monday brings.
Hello, ten thousand callers.
A real call, start to finish. The only edit is two seconds of silence where the names were.
One platform, two ways to use it
The same runtime underneath, so latency and reliability do not change with the job.
Driving real results for teams that ship
To first word, on live calls
Measured end to end on real phone calls. Where you land depends on your telephony provider, not the runtime.
Other calls affected when one fails
A stuck call restarts on its own in about 40 ms. Nobody else on the platform notices, and nobody gets paged.
From scope to live traffic
One real workflow, scoped, built, tested on real calls and put on a number your customers already dial.
What teams run on it
Eight calls teams put live first.
Lead qualification
Budget, timeline and intent, asked in context.
Customer support
Answers from your knowledge base, warm handoff when it cannot.
Appointment desk
Books, moves and confirms against your live calendar.
Payment reminders
Calls before the due date and takes the promise to pay.
HR screening
First phone screen at volume, same questions every time.
Real estate
Answers listing questions and books the site visit.
Renewals
Reaches the customer before the plan lapses.
Feedback calls
Real answers, a day after the service.
The call is half of it. The follow-up is the rest.
Build the engagement, not just the conversation. Write a rule once and every call that matches it carries itself to the next step.
The call ends
Every call on the account, or narrowed to one campaign or one agent.
The outcome meets a rule
Interested, callback, unreachable — whatever the conversation actually landed on.
The follow-up fires
While the call is still warm — one rule can fire all three.
- Email your team
- Email the lead
- Open a task
Every run is logged
Runs, success rate and a full activity trail, rule by rule.
Rules stack, and priority decides which one speaks first when several match.
