Voice AI In partnership with AI Overlords

Voice agents that actually pick up.

Voice AI that answers the phone, holds the conversation, books the appointment, updates the CRM, and hands off to a human when it matters. Full-stack builds on the partner best suited to the use-case.

Partners we resell + implement

Seven stacks. One integrator.

We do not pick a partner and force-fit. We pick the partner that fits the outcome.

ElevenLabs

Conversational AI, Voice Lab and TTS. Production-grade voice cloning. Best-in-class for warmth and multi-lingual reach.

Vapi

Real-time voice orchestration. Best when latency and interruption-handling are the whole game.

Retell

Call-centre-shape workflows. Best when you need a Voice AI that behaves like a good agent from day one.

Bland

Outbound-first stack. Best for structured qualification and appointment-booking at scale.

Deepgram Nova

Best-in-class transcription. When accuracy on live calls is the deal-breaker.

Cartesia Sonic

Ultra-low-latency generative voice. When the model has to feel human, not scripted.

Speechmatics

Enterprise-grade STT with strong accent coverage. Public sector and regulated industries.

PolyAI · Play.ht

Enterprise conversational voice and lifelike TTS. Chosen where brand-voice or vertical fit demands it.

Twilio Voice + Verify

Carrier-grade phone plumbing and OTP. Every voice agent we ship wires into Twilio for numbers, SIP, and identity.

Custom on GCP

When none of the above fit, we build on GCP with open models. Rare, but we do it.

Integration + orchestration.

Voice partners are only half the stack. We wire them into your CRM and your data with the same set of tools we use across every engagement.
