Phaeth Echo · for marketers

Test the campaign on a copy of your customers, before you spend a euro on the real ones.

Echo turns the customers you already have into a living, synthetic audience built from your data, then lets you test any message on it: from the first click all the way to the sales call.


Today, you only learn after you've already paid.

Dashboards report last month. Panels ask a stranger. A/B tests make you spend the budget first. The real test environment is the live campaign, so the loop never closes.

📊Read what happened
🤷Guess again
The answer to "what should we send, and to whom?" is never in last month's dashboard. It has to be modelled, before the send.

Attention tools test the asset. Panels invent a customer.

Two kinds of AI each close half the gap. That half-open gap is exactly where Echo lives.

Today's tools

  • Attention AI knows the creative, not your customers, and stops at "will they look"
  • Synthetic panels build a customer from generic data, and only ask them to talk
  • Looking is not buying; a survey answer is not an action

Echo

  • Your customers, not a panel of strangers
  • Real actions, not survey answers
  • Real outcomes, from the first click to the sales call

Attention tools tell you if they'll look.
Echo tells you if they'll buy.


Built from your data. Grounded in fact, not invented personas.

Echo learns from the data you already own, who your customers are, what they've bought, how they've behaved, and builds a faithful synthetic stand-in for each one. Synthetic means privacy-safe by construction: the audience behaves like your customers without exposing any individual person.

Your customers Algorithm + LLM Synthetic audience
Real records in. A privacy-safe population you can run experiments on, out.

Five steps, no models or schemas to think about.

Echo never asks you about vectors or schemas. It asks one question: what are you about to send, and to whom?

01
👥

Add your customers

They become a synthetic audience built from your data.

02
🧩

It clusters & enriches

"North, rooftop solar, opens every email" becomes a filter you click.

03
✉️

Test any action

An email, an SMS, a price, a whole journey, before you send it.

04
📈

Score the whole chain

The early signal (will they click) and the money signal (will they convert).

05
🔁

Simulate, act, compound

Ship the winner. Every real outcome makes the next simulation sharper.


We read the psychology of your audience.

Every message has a fingerprint Echo can read: the words, the image, the emotion. Echo turns all of it into signal, then connects it to whether your customers clicked, replied, or asked for a call.

Not another neuroscience tool, the twin that puts the best ones to work.

The honest part that makes the dream real: whatever a Neurons or a HABS predicts is treated as a clue, not a verdict, and every clue is checked against what your customers actually did. If a score doesn't move your real numbers, Echo drops it. Dream, grounded in fact.


From first click to sales call, modelled before you hit send.

Echo scores the early signal and the later, money signal, the part attention tools and survey panels can't give you, and the part finance actually asks about.

One score, end to end. The numbers are computed from a model trained on your customers' behaviour, never improvised.

Plugs into the stack you already run.

Echo reads from your CRM and activation platform, runs the simulation, and pushes the winner back to the channels you ship on. No rip-and-replace.

Proof on your data, not slideware.

We prove value directly, on your own customers. We build the twin, then test its predictions against outcomes we held back, that the model never saw. If they hold to a bar we agree up front, you haven't read a case study, you've watched the method work.

01

Bring your data

Your CRM and campaign history. We build the living copy of your customers.

02

Agree the bar

We set the accuracy target together, up front, before any prediction is made.

03

Watch it predict

Echo predicts outcomes we deliberately hid. The twin has to match reality to pass.

04

Keep what holds

If it holds, you scale it. If it doesn't, we say so and stop. No confident guesses.

Personas are made up.
Echo is built from your customers.

Start a pilot on your own data, and see the loop close before you spend.
