Company

Research that ships on a live number.

Kupe is a product of iNavLabs. We are a research-oriented company: small models, live memory, and voice agents that pick up, remember the customer, and finish the job — on the phone and on WhatsApp.

Who we are

A research-oriented company.

The work that matters on a live call is latency, barge-in, language, and the beat after someone stops talking. That is where most voice products die. That is where we spend our time.

We do not treat research as a side blog. We train small models, keep memory live across channels, and put agents on numbers that actually pick up. If a lookup takes 800ms, the caller still hears a person thinking — in the language of the call. If they interrupt, the agent stops. If they switch from phone to WhatsApp, they are not starting over.

The same stack runs in the hub and on the Realtime API. Build this afternoon, or wire the agent into your app. Either path answers production numbers — not a demo that dies the first time someone interrupts.

Collections, clinics, carts, after-hours IT. The agent books, collects, follows up, and hands off warm when the account is messy. You pay for minutes, not seats. Kai is the operator inside the product; customers talk to the agents you deploy.

We publish what we run. ThinkSpark, voices, the Realtime path — the research is the product, and the product is on the line.

What we work on

Four problems that decide if a call lives.

Presence on the line

Interruptions that work. A thinking sound instead of dead air. The caller should never wonder if the number is fake.

Memory that follows them

Phone, then WhatsApp, then a transfer. The 2 BHK, the Saturday slot, the pin they already received — still there.

Models that fit the call

Small models next to the live session. We publish the weights we run. Research that never left the lab is not research here.

Agents that finish the job

Collections, appointments, recovery, after-hours. Book, collect, follow up, or hand off warm. Minutes, not seats.

How we ship

Lab hours, then a number that answers.

  1. 01

    Measure the hangup, not the demo

    Time-to-first-word, barge-in, takeover rate. Sentiment is a slide. Those numbers are a staffing plan.

  2. 02

    Publish what we run

    Model cards, research write-ups, and the same Realtime API the hub uses. No private stack for the marketing site.

  3. 03

    India is a first-class constraint

    DND, KYC, residency, and languages people actually speak are product surfaces — not a locale pack.

  4. 04

    Same brain in the hub and in code

    Kai is the operator you talk to inside the product. Customers talk to the agents you deploy.
