Early access: bring your customer list and your Twilio numbers Get started
Phone outreach on autopilot

Sales calls that run themselves.

Give Kata your customer list and your offer. Hear a test call on your own phone first. Then AI agents call every lead, test scripts and voices against each other, and keep the ones that bring orders.

How it works. Bring the list, it makes the calls.

List

Drop your list.

A CSV of customers or leads with phone numbers, or push them from your CRM.

Numbers

Add your numbers.

Your Twilio numbers. Each lead gets a local one when you have it.

Scripts

Say what you offer.

Your AI agent writes the first script from one sentence.

Calls

AI agents call.

In each lead's local hours, with retries when nobody picks up.

Learning

It gets better.

Losing scripts stop. New ones are written from the winner.

Features. Split tests on every call.

Each call is a data point: who picked up, how long they stayed, what they said, and whether they bought. Kata reads all of it and moves the next calls to what works.

Scripts compete.

Openers and scripts run side by side. The losers stop, the winner gets more calls, and new versions come from it.

Voice engines compete too.

Run the same script on two engines and keep the one people stay on the line with. Swap engines when better ones ship.

Your numbers, a local one first.

Calls go out over Twilio from the numbers you add.

Lead's timeTue 10:40

Calls at the right hour.

Kata calls in each lead's local hours, caps calls per number per day, and spaces out the retries.

✓"Stop calling me"never again

Numbers that stay clean.

A number nobody answers slows down, then pauses itself. Anyone who says stop is never called again.

Use cases. Start with the customers you already have.

Your best leads already bought from you once. A call brings more of them back than another email, and Kata finds the words that do it.

01Win back dormant e-commerce customers.

Call everyone who ordered once and never came back. Remind them what they bought and make the offer.

02Bring back lapsed players.

For casinos and gaming sites: call players who went quiet with your offer, and reach VIPs before they leave.

03Upsell current customers.

Call about the upgrade, the renewal or the add-on, and hand the interested ones to your team.

Made for your agent.

No script editor. Claude, ChatGPT or your own agent runs Kata through its API and MCP server: it sets up campaigns, places test calls and reads the results.

Then ask your agent

It learns from

Questions.

Does it sound like a robot?

It uses speech-to-speech voice models that listen while they talk, so people can interrupt them like a person. Kata tests voices and engines against each other and keeps the ones people stay on the line with.

Can I listen before it calls my customers?

Yes. Place a test call to your own phone first. Every call after that has its recording, transcript and outcome, and you can pause a campaign at any time.

Do I need Twilio?

Yes, for now: calls go out over Twilio from numbers you add. More providers, picked by country, come next.

Is it legal to call my customers?

It depends on your country and the consent you hold. You stay the caller. Kata calls only in local hours, never calls anyone who said stop again, and says it is an AI when asked.

How does it learn what converts?

From pick-ups, talk time and the outcome of each call from day one. Connect your shop or site and it also learns from orders and their value, and keeps the scripts that bring money.

What does it cost?

Prices are not public yet. Early-access teams get them before their first real call.

Part of Kata. One account for calls and email, run by your agent.
