Discover
We map your call flows, integrations and goals — and define what success looks like.
- STEP 02
Design
We script the agent persona, prompts, fallbacks, and human handoff rules with you.
- STEP 03
Build & integrate
We build the apps, backends and VOIP plumbing — SIP trunks, CRM, calendars, webhooks. End-to-end tested before you ship.
- STEP 04
Launch & optimize
Go live, then iterate weekly using transcripts, sentiment and conversion data.

A software studio that owns the whole voice-AI stack
We're a small, senior team that ships custom software for one focused mission: putting AI on real phone lines, in real businesses.

We don't ship a template. We design your call flows, build your apps, integrate your systems and run your telephony — as one coherent product.
One team, full stack
Front-end, mobile, backend, AI, VOIP and DevOps under one roof — so your voice agent never gets stuck behind a vendor handoff.
Works with your stack
Bring your existing SIP trunk, CRM, calendar, ERP, helpdesk or data warehouse. We integrate, we don't replace.
Measurable ROI
Conversion, containment, CSAT and cost-per-call tracked from day one. You see the impact, not just the demo.
Clear contracts
Proper LLC entity, NDAs, MSAs and DPAs ready on day one. Predictable scope, predictable billing, no surprises.
Senior team, direct line
You work with the engineers building your system — no hand-offs to a junior pool, no ticket queues.
FAQ
Answers to the questions we hear most
Do you only build voice agents, or full software products?
We're a software studio. We build the complete product around your voice AI — web apps, mobile apps, backends, VOIP infrastructure, integrations, dashboards and analytics. The voice agent is the headline feature; everything around it is custom-engineered for your business.
Can the AI agent connect to our existing SIP trunk?
Yes. We integrate with most providers — Twilio, Telnyx, Vonage, Plivo, Bandwidth, as well as self-hosted Asterisk or FreeSWITCH stacks. Bring your trunk credentials and we handle the rest.
Which languages do your voice agents support?
We currently ship agents in English, Arabic, French, Spanish, German and Italian, with more available on request. Multilingual single-agent flows (auto-detect + switch) are also supported.
Where is call data stored and how long do you retain it?
Audio, transcripts and metadata are stored encrypted at rest in the region you choose. Retention is configurable per integration, including zero-retention modes for sensitive workloads.
Can we use a custom voice or our brand persona?
Absolutely. We support custom voices (cloned with consent), bespoke personas, scripts, and tone-of-voice guidelines so the agent sounds like part of your team.
Which CRMs and calendars do you integrate with?
Native integrations for HubSpot, Salesforce, Pipedrive, Google Calendar and Microsoft 365 / Outlook. Anything else is straightforward via webhooks or REST APIs.
What kind of latency should we expect on calls?
Typical end-to-end response latency is under 310ms. We run a streaming speech-to-speech pipeline — audio in and audio out — so conversations feel genuinely real-time.
How is pricing structured?
Two parts: a fixed scope for the custom build (apps, integrations, telephony setup), then a transparent per-minute or per-seat rate to operate the platform — telephony, AI inference and hosting included. No surprise overages.
How long does a typical implementation take?
Most engagements go live in 3–6 weeks for a focused build, and 2–3 months for larger products that include web/mobile apps and deep integrations. We ship in iterations so you see progress every week.
