Concept testing

Concept testing at the speed
of a Slack thread

Put a product idea, a feature, a landing page, a name, or a pack design in front of 185 personas and read the resonance, the dissent, and the objections that surface — in the time it takes to post a message, not the six weeks a traditional concept test would cost you.

A lock I set myself? Yes. That's the version of "discipline" I'd actually pay for. I'd want to feel in control of it, not policed by it.
Daniel, 41 Dissent
The concept's fine; the framing scares me. "Lock" sounds like the app gets to say no to my own money. Rename it and I'm in.

Test the concept against the people who'd actually buy it

A concept only resonates if it resonates with the right audience, so the test starts with the room. Compose a panel by type, generation, geography, channel propensity, and lifecycle stage — the same fields your media team already targets — and you're reading reactions before a recruiter would have returned your first email.

Swap in a sceptical segment, a power-user segment, or a brand-new market and run the same concept again to see where it travels. Browse the full persona library to choose who sits in the room, then turn the loop into a repeatable synthetic focus group whenever an idea needs pressure.

Run · then read the verdict

Resonance, dissent, and the objection you'd have missed

Present the concept — a feature spec, a landing page, a name, a packaging mock — and run the session. When someone hesitates, probe the way a good moderator would: ask the follow-up, surface the real objection, and watch where the room agrees and where it splits. The synthesis hands you a resonance score, the dissent worth taking seriously, and the exact phrases people reached for.

That language is the part you can't get from a survey scale. It tells you whether a concept dies on the name, the price, or the premise — and gives you the words to fix it before a single dollar of media spend rides on it.

Where it fits

Where concept testing fits in your week

Most concepts never clear the bar for a formal study. The idea lands in a doc on Monday, gets argued over in standup, and ships on a hunch by Thursday — because the only honest option was a six-week panel nobody had time or budget to run. So the strongest opinion in the room wins, and you find out whether the concept worked after the launch, not before it.

Synthetic concept testing fills that gap. It gives you structured, divergent reactions in minutes, for the long tail of decisions where the alternative isn't a better study — it's no study at all. Use it to choose between two feature directions, to sanity-check a name before legal clears it, or to find the objection your team has stopped seeing. Once the concept is sound, carry the same room into message testing to sharpen how you say it, and read the how it works walkthrough to see the full compose, run, probe, and synthesis loop end to end.
