How it works

From one decision to clear evidence, in six steps.

Every study starts with the decision you need to make, not with a method.

  1. Step 01

    Define the decision

    We start with the specific creative choice in front of you: which cut, which opening, which onboarding flow.

  2. Step 02

    Design the study and agree methods

    We propose the audience, the session format and the methods, and state what each can and cannot support.

  3. Step 03

    Recruit adult participants

    Adults matched to your audience by language and city, who receive participant information and give consent.

  4. Step 04

    Run the session

    Participants watch, read or play your content in a controlled session, with your content protected under NDA.

  5. Step 05

    Analyse feedback and signals together

    Researchers read participant feedback alongside any signals, never signals on their own.

  6. Step 06

    Debrief

    We walk your team through findings, uncertainties and recommended next tests.

A physiological or behavioural signal does not identify a person's internal emotion with certainty. Findings need context, participant feedback and human interpretation.

Our research principles

  • We inform decisions, never automate them.
  • Feedback always; signals only where they add evidence.
  • Adult, consenting, paid participants.
  • We report uncertainty honestly.
  • When comparing versions, we rotate viewing order or use separate groups to reduce bias, and individual responses are always collected before any group discussion.

Audience size, languages, timeline and price are set in each proposal.
