What tools do you use to plan and run growth sprints?

Lately I’ve been talking to other founders who struggle to bring structure to growth: everyone’s testing ideas, but few track experiments systematically

I ended up building a Notion system to keep everything in one place (diagnostic → sprint plan → hypothesis scoring → go/kill decisions)

Curious what you all use - Notion? Airtable? Sheets?

Would love to compare setups 🙌
