Collaborate with everyone
Experimentation works best when tapping into everyone's creativity. Shared workspaces give teams the same tools to craft hypotheses, variations and more, while highly-visual (and shareable) calendars help track all in-flight and upcoming activity. Need more experiment ideas? Crowdsource ideas with customizable intake forms — and then turn those ideas into winning variations.
- Idea submission forms & backlog
- Workflows, variation design tools, approval checklists
- Shareable calendars & results repository
