Day 5

Compiled notes from all 4 calls. 3 out of 4 said they'd try a tool that does this. Created a simple landing page with waitlist form.
This is giving me ideas for my own project. Thanks for the transparency!
Day 4

2 more calls. One user described exactly the workflow pain I'm trying to solve — even showed me their clunky spreadsheet setup. Strong signal.

Had 2 user calls today. Key insight: both mentioned the problem but their current workaround is 'good enough.' Need to dig deeper into the friction.
Bookmarking this challenge — going to reference it when I start mine.
