Bringing AI voice agents to life

Convexa helps businesses handle calls, qualify enquiries, book appointments, and support customers with managed AI voice agents built around real workflows.

Surveys

Runs feedback calls, then summarises the themes.

Renewals

Handles renewals, retention, and win-backs.

Reception

Answers calls, takes details, and routes callers.

Qualification

Qualifies leads and summarises every enquiry.

Booking

Books, reschedules, and confirms appointments.

Designed for teams handling high call volumes across every shift
Builtto scale.

Voice agents that hold up under real volume — thousands of concurrent calls, handled with the same care as the first.

What’s behind the service

One service.
Every part of the call.

Voice models, telephony, orchestration, knowledge, and observability — we run them as one service, so the agent sounds right and your team stays in control.

Voice-native reasoning

A speech-to-speech model designed for live conversation — not a chatbot with text-to-speech glued on. Plans, asks, confirms, recovers.

Sub-second latency

Median response around 620 ms across our global edge. Conversations feel natural enough that most callers don’t ask whether they’re speaking to a person.

Carrier-grade telephony

SIP, PSTN, WebRTC, and SMS. Port your existing numbers or buy new ones across 24 countries.

Grounded knowledge

Agents draw from your own documents, CRM, clinical systems, and tickets — with citations on every answer, not invented detail.

Full visibility

We share clear reporting on every call — recordings, transcripts, and outcomes broken down by intent — so you always know how your agent is performing.

Enterprise controls

SSO, audit logs, regional residency, signed DPA, PCI DSS-compliant payment handling, UK GDPR — ready for your security review from day one.

Built for real conversations

Trained on the
realities of a live phone call.

Cross-talk, regional accents, hold music, background noise, calls put on speaker mid-sentence — our models are tuned for the audio operators actually hear, not for studio conditions.

A UK field-services operator

“Convexa resolves much of our after-hours dispatch load autonomously — so we don’t need an on-call engineer waiting by the phone.”

“A patient-reminder agent can meaningfully cut missed appointments over a quarter, without adding to the front-desk workload.”

“Consolidating several collections vendors into a single Convexa agent can simplify the operation and lift recovery rates.”

Sounds like a person.
Behaves like infrastructure.

Eleven foundation models and a runtime engineered for 12,000 concurrent calls per workspace sit behind the service. You never touch any of it — we run it so the agent stays fast and reliable.

A managed service

Your agents,
designed and run for you.

You don’t configure software or manage a platform. We design each voice agent around your calls, your systems, and your goals — then run and improve it for you.

Designed for your business

We map your call flows, write the prompts, choose the voice, and connect your tools — then test against real scenarios before going live.

Run and improved for you

A dedicated solutions engineer monitors performance, refines prompts as patterns emerge, and ships improvements — so the service gets better over time.

Consistent quality

Every call,
graded. Every week,
better.

We score every interaction against your rubric — outcome, sentiment, compliance, drop-off — and feed the weakest calls back into review. Your agent gets steadily better, and we handle the tuning for you.

Outbound campaigns

Outbound batches with smart retry logic, Ofcom-aligned dial windows, and TPS / CTPS scrubbing.

SMS follow-up

Web & in-app

A drop-in widget for browser-based calls, built on WebRTC.

Built for security

Designed for scale,
reliability, and trust.

Convexa has been through the kind of security review your team will run. The artifacts are ready on day one, so procurement isn’t the bottleneck — including the controls that matter in regulated sectors like healthcare and financial services.

Built on ISO 27001-certified infrastructure. Statement available on request.

NHS DSPT

Built on NHS DSPT-compliant infrastructure for healthcare workspaces. ICO-registered.

Omni-channel

Managed conversations across
every key channel.

Convexa helps businesses handle calls, messages, and connected workflows through a managed AI voice agent service. Our team designs, configures, and improves the communication flow around your business — without clients needing to manage software themselves.

Voice Call

Handle inbound and outbound phone conversations with managed AI voice agents built around your workflows.

Chat

Support web and in-app conversations where needed, with responses shaped around approved business information.

SMS

Send follow-ups, confirmations, reminders, and updates through managed messaging workflows where configured.

API

Connect approved systems and workflows where possible so call outcomes can support the tools your team already uses.

Integrations

Integrate seamlessly with
the tools you already use.

Convexa works with the systems your business already relies on — CRM, support, telephony, payments, collaboration, and healthcare tools. Our team connects and maintains these integrations as part of your managed deployment, where your systems allow it.

Frequently asked.

Natural enough that most callers don’t ask whether they’re speaking to a person. The best way to judge is to hear it — try the live demo above, and we’ll share example recordings on a call.
