For agencies that don’t like to lose money
Have all of your customers in your pocket.
Marketplay turns a client’s own customer data into psychology-backed digital twins of real customers. Interview them, pressure-test them, put real creatives in front of them — and see, with the reasoning behind every reaction, exactly where you win.
Grounded in your client’s real data and psychology-backed behavior studies. GDPR-compliant. Reasoning shown for every answer.
Never let a good idea go unexplored.
Every creative deserves a first audience — one that reacts, with reasons.
Test every possible creative version — hook to CTA.
Upload the ad / reel, the copy, the email, the landing page. See the reaction at every stage — the hook that grabs, the offer that stalls, the CTA that closes with the reasoning behind each one. Then use the best one.
Every run saved as its own version.
What would make you switch to a competitor?
If onboarding took longer than ten minutes, or support made me chase them.
Ask your customers what they’d actually buy.
Before you pitch the promotion or launch the product, ask the customers who’d actually buy it. Probe what they’d pay, push back when they hedge, follow up on what they really meant. The twin remembers every answer, ready for the next question.
See your product through five pairs of eyes.
Put five customer types in one room and watch how they react — who loves it, who hesitates, who talks the others out of it. Independent answers give you a clean read; open cross-talk shows how opinions spread. Either way, you know how the room sees it before you ship.
Agencies spend more than a third of every campaign finding the perfect fit.
On average, agencies burn over 35% of campaign time and budget on experiments and research. Marketplay cuts that by 93% so the guessing happens in minutes, before release, instead of the end of the month, when you have lost customers.

How a twin is made
From client data to digital twin in minutes.
Import
Upload a client’s customer data — CSV, call audio, transcripts, CRM logs. No new system to configure.
Thin customer segments are flagged, with optional enrichment.
Detect
Marketplay finds the distinct customer segments already sitting in that data.
Empirical clustering, built on psychology and real-world behavior studies.
Select
Choose which segments become twins. Edit them until you lock them. Once locked, they’re grounded for good.
A grounding indicator travels with every twin.
Or none you want to share? That’s fine. Start from a described audience or reuse a twin from another client, named transparently. Our twins are built on psychology and real-world behavior studies, and they sharpen the moment real data arrives.
The evidence standard
Every answer arrives with its evidence.
Grounding
Every twin rests on psychology and real-world behavior studies, and shows what it’s built from — real client data, public benchmark, or psychological model — on every card.
Reasoning
The why is visible by default at every stage, per answer. Never hidden behind a click.
Isolation
Clients are partitioned at the data layer. No leaks between accounts, we are GDPR by design.
