Key insight: Slack's 90-day deletion is intentional upsell strategy, not technical limitation — there's a frustrated audience of budget-conscious teams ready to pay $10/month to outsmart it.

The Problem

Slack's free tier deletes messages after 90 days, forcing teams to either pay $12.50/user/month for archive access or lose critical context about decisions, code discussions, and bug resolutions. Teams waste hours re-discussing solved problems because the thread history is gone.

Target Audience

Bootstrapped startups, agencies, and non-profits using Slack free/pro tiers (teams under 50 people) who can't justify $600+/month for archive costs but desperately need searchable message history.

Why Now?

Slack pricing has become a pain point post-pandemic as companies tighten budgets; teams are actively looking for cheaper alternatives to unlock their message history without paying Slack's premium tax.

What's Missing

Existing solutions are either too enterprise-focused or require manual exports; no slick, automated, affordable archive-and-search tool exists between free Slack and Slack Standard pricing.
