Conceptmates

Put an agent on your WhatsApp number.

Conceptmates agents answer your customers in chat, reply to voice notes, and pick up live voice calls — grounded in your knowledge, bound by your rules, on the official WhatsApp Business Platform.

Create your agentSee how it works

Free while in early access. Bring your own WhatsApp Business number.

  • Official Cloud + Calling APIs
  • Voice engineered for sub-second replies
  • Durable, idempotent message handling
  • Tenant isolation by default

One agent. Three ways your customers talk.

Chat

Answers, not autoreplies.

Your agent holds the whole conversation — it remembers the thread, pulls from your knowledge base, and cites what it used. When it shouldn't answer, it says so and stays in its lane.

Voice notes

They send a voice note. It sends one back.

Customers in WhatsApp-first markets talk more than they type. Your agent transcribes what it hears and replies with a real, playable voice note in your agent's voice.

Live calls

It picks up the phone.

Real-time voice conversation on a WhatsApp call — streaming end to end, engineered to speak back in under a second. Chat platforms stop at text. This one answers the call.

From zero to answering.

The path a new account walks — no YAML, no redeploy, no engineers required.

  1. 01

    Create your agent

    Persona, tone, boundaries. Configuration, not code.

  2. 02

    Connect your number

    Your WhatsApp Business account, your credentials — pasted once, encrypted, never shown again.

  3. 03

    Add knowledge

    Upload what your agent should know. Answers come grounded and cited.

  4. 04

    Publish

    Draft and live are separate. Publish when ready, revert when not.

Built like infrastructure, not a demo.

Streaming at every layer
Speech, model, and voice never wait for each other.
Durable by default
Every message survives crashes and retries — jobs are durable, and every handler is idempotent.
The 24-hour window, enforced in code
WhatsApp's messaging window is enforced in code, not in a training slide.
Keys that can't overreach
API keys are hashed at rest and scoped — a runtime key cannot read your configuration.
Tenant isolation by default
Every query is scoped to your organisation.
Deployed in Mumbai
Close to your customers.

The boring parts are the product. Everything above is enforced in code and covered by the test suite.

Scoped by design.

WhatsApp's rules are our rails.

Agents are scoped to their job by design — per-agent guardrails deflect off-topic use instead of improvising. A tutor teaches; a support agent supports.

Built for India's DPDP Act.

Consent flows, minor protections, and recording notices on calls — built for the law of the market we serve.

Your secrets stay secret.

Credentials are write-only — the dashboard never shows a stored secret back. API keys are hashed at rest and scoped.

The first agent on the platform is ours.

We didn't launch with a slide deck. We launched with an English tutor that teaches over chat, replies to voice-note practice, and holds live speaking calls — for learners preparing for exams, interviews, and better jobs. Building it end to end is what shaped the platform.

Yours is next: support, bookings, tutoring — if it talks to customers on WhatsApp, it fits.

Bring your use case

An API when you want it. A dashboard when you don't.

  • Scoped keys

    A runtime key can send messages to your agent — and can never read your configuration.

  • Webhook tools that call your systems

    Your agent can call your HTTP endpoints — HMAC-signed, capped and retried, and never exposed on live voice calls.

  • Your system can build agents

    Create, configure, and publish agents from your own backend over the management API.

One turn with your agent — same brain, your channel. Per-end-user memory via user_id.

Questions, answered plainly.

Is this official WhatsApp?

Yes. Conceptmates runs on the official WhatsApp Business Platform — the Cloud API for messaging and the Calling API for voice — with your own WhatsApp Business number.

Does it really take voice calls?

Yes, where WhatsApp calling is available. Calls stream end to end, engineered for a first reply in under a second.

What does it cost?

Early access — free while we onboard the first partners. Pricing lands with general availability.

What languages does it speak?

English today. Built in and for India — Hinglish and Indic voices are on the roadmap.

Where does my data live?

In the Mumbai region, isolated per organisation. Credentials are write-only and encrypted; API keys are hashed at rest.

Your customers are already on WhatsApp.

Answer them there — in chat, in voice, on calls.
