The problem

Teams don't talk to the company's most important asset: their customers.

Not because they don't care, but because traditional research is too slow and too expensive to keep pace with the customer decisions teams make every week. So they skip it, skim it or do it too late, and ship on assumptions.

The vision
We don't want to replace real humans in research. We want every team to talk to them more, better and faster.
01

More iterations

Explore, test and re-test with Echo before you spend a euro on fieldwork.

02

Smarter questions

When you do talk to real customers, you already know what to ask.

03

Fewer assumptions

Replace "we think" with "we tested", and take the risk out of big decisions.

How it works

Three steps to unlimited insight.

Echo is trained on three layers of data: your own customer data, our proprietary research pipeline and publicly available sources. It creates digital twins that answer like your real customers, or like the new segments you want to reach. No need for a mountain of data: a sharp brief or a few past studies is often all it takes.

STEP 01 · INGEST

Audience creation

Start from a short brief or a few existing studies. Echo extracts a blueprint of your customers and generates a grounded synthetic population, with distinct sub-groups discovered from your own data.

  • Recreate your existing or new customer segments
  • Generates synthetic personas with distinct traits and behaviours
  • Extracts social, cultural and cognitive nuances
85–93%accuracy against real human interviews
STEP 02 · SIMULATE

Research design

Design surveys, interviews, or concept tests. Echo runs simulations at scale, with no recruiting, no scheduling and no respondent fatigue.

  • Up to thousands of respondents per project
  • Ask any question, visual or textual
  • Run quick and unlimited iterations
STEP 03 · VALIDATE

Insights report

Decision-ready intelligence with emergent themes, outlier signals, and key recommendations, in minutes.

  • Executive summary for quick decision-making
  • Question-by-question breakdown for detailed analysis
  • Full, readable transcripts of every synthetic interview

How we build digital twins, and how we measure them against real people.

From our customers

Evidence that moves the decision forward.

Teams use Echo to settle strategy debates, build go-to-market plans and explore new segments, in weeks instead of months.

2 months
to build a complete go-to-market strategy, instead of 6–8. Over 3,600 simulated B2B customer interviews.
"We planned and optimised our entire GTM strategy and market share simulations with Echo, building value propositions that truly resonate with our customers."

Use cases

From first concept to the campaign that launches it.

Built for insights, product and marketing teams who make customer decisions every week, not once a year. Here's what they bring to Echo.

01

Concept & product validation

Screen new concepts, packs and flavours before a single prototype is made. Keep the winners, kill the rest early.

"Which of our new product concepts wins with younger families?"

02

Campaign & message testing

Know which message lands before you commit the media budget. Test tone, angle and claims per segment.

"Which message makes switching to us feel easy, not risky?"

03

Pricing & proposition

See how customers weigh price, bundle and value, and where your proposition tips from "maybe" to "yes".

"How do customers react to a subscription compared with a one-off price?"

04

Niche & hard-to-reach audiences

Talk to the customers you can't recruit: C-level buyers, specialists, high-net-worth or niche consumers, in B2B and B2C alike.

"What would make hospital procurement leads switch suppliers?"

05

Customer journey & CX

Walk your journey with different customer types. Find the friction before your real customers do.

"Where does our onboarding lose new customers in the first month?"

06

Competitor customer insight

Interview your competitors' customers, the people who never answer your surveys. Find out what keeps them there, and what would make them switch.

"Why do customers of a digital challenger bank stay, and what would bring them to us?"
