What is Hubble's Participant CRM?
Hubble's Participant CRM brings your research participants into one searchable contact list. Instead of rebuilding an audience for every study, you can keep participant profiles, research history, and contact details together and re-recruit people for future research.
How can I add participants to the CRM?
You can upload an existing participant list using a CSV or Excel file, or add contacts individually by entering their details manually. This makes it easy to bring your existing research audience into Hubble and build a reusable participant panel.
What information is stored in a participant profile?
Each profile can include screener answers, participant attributes, notes, session history, and past research participation. You can also track consent and incentive payouts, giving your team useful context before inviting someone to another study.
How do I find and re-recruit the right participants?
Search and filter participants by their attributes, screener responses, and previous sessions. You can also create groups to organize different personas or audience segments, making it easier to find and re-recruit the right participants for future studies.
Can I track past studies and avoid contacting participants too often?
Yes. Participant profiles show study and session history, including when someone was last contacted. Hubble also respects contact limits, helping you manage repeat invitations across studies.
How do participant incentive payments work in Hubble?
To pay participant incentives, connect your own Tremendous account to Hubble. Once the integration is set up, you can send payouts to participants through Tremendous directly within Hubble.
