Enrolment is free, and it always will be — we are paid by the research sites, never by you. How that works

How it works

Four steps, and three of them happen before we know your name

The order is the whole point. Most routes into research take your details and then look; this one looks and then, only if there is something worth it, asks.

  • No account to create
  • No call unless you ask for one
  • No charge at any stage
  • No sharing beyond the one study you pick

Screening is still a separate step

Matching the published criteria is not the same as being accepted. The research team makes that decision in person.

What actually happens, in order

Nothing here is automated away. Where a person is involved, it says so, and where nobody is, it says that too.

1Step

    Read the criteria

    Every area page sets out what studies in it ask about and what tends to rule people out. Nothing is summarised away, because the summarised version is the one that wastes your time.

    2Step

      Run the comparison

      Answer what the studies actually ask. It runs in your browser against the published criteria — no account, no name, no number, nothing sent anywhere.

      3Step

        See the answer, including the no

        If you fall outside, the check names the line you missed. If you fall inside, it shows the visit schedule and the travel before it asks you for anything.

        4Step

          Decide, then hand over once

          Only if you choose to go ahead do your details go anywhere, and then to one research site for one study. The team there screens you and takes consent in person.

          Money

          Who pays for this, and who does not

          You never pay

          Not for the check, not for being put forward, not for anything else. We do not take card details and there is no account to upgrade.

          Research sites pay to be listed

          That is the whole business model, and we would rather state it than have you wonder. It does not change what the criteria say or how the comparison runs.

          Studies may reimburse you

          Many pay for time and travel, and early-phase studies often pay more. That comes from the study, is set by the study, and is nothing to do with us.

          We are not paid per person enrolled. A fee per head would give us a reason to push people toward studies they only just fit, and the whole point of the comparison is to do the opposite.
