One observation : finding testers was more than difficult

À travers son expérience d'UX designer, France réalise que la difficulté de recruter des testeurs est une constante du secteur: designers et équipes produits sont convaincus de la nécessité de baser leur travail sur les insights utilisateurs pour créer des outils utiles et impactants mais ils font face à une complexité logistique et des tâches chronophages qui leur font perdre du temps dans leur travail au quotidien.

Cette situation donne lieu à des compromis qui réduisent la pertinence de la rechercher utilisateur au sein des organisations:

Through her experience as UX designer, France realized recruiting testers is a shared struggle in the field: designers and product teams are convinced of the importance of putting user insights at the center of their work to create useful and impactful tools. However, they face time consuming tasks logistic complexity which impacts their ability to focus on their users.

This situation leads to compromises which reduce the relevance of user research within organizations:

  • testing with colleagues, friends or testers that are not related to their customer target
  • make do with less or no tests at all
  • work with traditionnal actors such as panels and agencies whose deadlines are long (several weeks) and costs higher

One idea: a platform to manage testers

This is how the idea came of a solution to harness to power of automation and the targeting of social media to offer self-service qualified testers on-demand with shorts deadlines and accessible pricing to accomodate as many stakeholder in the field of user research as possible.

A tool which allows to manager the whole testers' recruitment value chain:

  • targeting
  • screening
  • selection
  • meeting scheduling
  • counterpart
