The company

Who builds this, and why the price is public

Vocapable is a product of Capstra Labs, LLC: AI voice agents that place and answer business phone calls on the customer’s own Twilio account and their own numbers. Every call returns a record, and the compliance controls behind it cannot be switched off.

The plain facts

  • Vocapable is a product of Capstra Labs, LLC.
  • Capstra Labs, LLC is a California limited liability company doing business as Vocapable.
  • Vocapable sells AI voice agents for US business phone calls.
  • Vocapable customers place their calls on their own Twilio account, at the carrier rates they already negotiated.
  • Every Vocapable call attempt returns an evidence file, and every conversation returns a transcript, a disposition and a structured outcome.

Agreements are governed by the laws of the State of California. Written contact is support@capstralabs.com, and the public code organisation is https://github.com/CapstraLabs. Vocapable runs on Twilio; no partnership or endorsement is implied.

What we build

The agent that holds the conversation. The campaign engine that keeps working your list after the team goes home. A CRM built for phone outreach rather than a deal pipeline with a dialer bolted on. A /v1 API for product resources, with signup, onboarding, and first-key setup in the browser. And an evidence file for every call attempt, so you can show your work later.

The speech recognition, the voice and the language model all run on hardware we operate. No hosted-voice API sits in the middle taking its cut, which is why we can print the whole rate card on a public page instead of quoting you per deal, and why the per-minute number on it is as small as it is.

The thesis underneath all of it: compliance is the product, not the paperwork around it. Four controls run in code on every dial, on every plan, at no charge, and nothing can turn them off. Not a plan upgrade, not an API field, not us on a support call. That is what makes your call log hold up when somebody asks to see it.

You can evaluate us without talking to us

The four things a buyer usually has to extract from a sales call are already published. Read them in an afternoon, decide, and then write to us with a real question.

The whole rate card

Every figure we bill is on the pricing page: the monthly base of each plan, the per-call-attempt fee, the per-minute AI rate on both commitment terms, and the volume ladder with the floor it stops at. The calculator on that page prices your campaign rather than a sample one.

The security posture, control by control

The Trust Center describes the security and data posture in plain prose, control by control. Most security questionnaires are already answered there before you send one.

A sample evidence file

A sample file for one call attempt, rendered the way the platform records it: which policy values bound the call, what the agent said, and what came back. This is the artifact you hand to somebody who asks how a call happened.

The security and data posture, control by control, is on the Trust Center, and every agreement is published in full at /legal.

Read the product, not the pitch

The sandbox is free and needs no card. Build an agent from your own pricing page and docs, run your script down the whole dial path with every gate live, and read the file it hands back. Everything else we publish is on the shelf.
