Interesting idea! Co-ops for SaaS are rare but possible. Some groups pool resources for benefits like healthcare. For open-source, a time-gated license like FSL could work, but it risks forking. Maybe focus on the product first, then revisit the structure later.

I love the idea behind your email sequence database! It's such a practical solution for marketers, solo founders, and teams who need inspiration and structure but don’t have the time to start from scratch. The categorization and sequencing of emails from 80+ companies is a huge win—it’s exactly what’s often missing from resources like Really Good Emails. The strategic approach you’ve integrated adds a lot of value for people trying to optimize their campaigns.

For improvements, one suggestion could be to add filters or tags that allow users to search for sequences by specific industries or campaign goals (e.g., welcome series, re-engagement, or post-purchase follow-ups). This would help users dive straight into the most relevant examples for their needs.

Looking forward to seeing how this evolves—great work!
