The backstory
DataFast is an indie analytics tool that connects site traffic to Stripe and Lemon Squeezy revenue, so founders can see which posts and channels actually pay. Its edge is simplicity and revenue attribution, not raw data volume. Free AI summaries inside Google Analytics and a wave of copycat indie dashboards squeeze it from both sides. It stays alive because the buying audience wants a small opinionated tool, not another enterprise console.
