Datafast
Analytics tool for entrepreneurs focused on revenue attribution, not vanity metrics. Tracks visitor journeys from first click to purchase and integrates with Stripe/LemonSqueezy.
DataFast is an analytics tool designed for entrepreneurs and founders who need to connect marketing efforts directly to revenue. It focuses on identifying which traffic sources and customer segments generate the highest LTV, moving beyond simple pageviews and bounce rates. It is currently loved by over 7,100 users and offers a 14-day free trial.
Key features focus on actionable growth:
- Revenue Attribution: Links payment processors (Stripe, LemonSqueezy, Polar) to traffic sources to show which channels drive paying customers.
- Goals and Funnels: Set custom goals (signups, downloads) and visualize the full visitor journey from initial click to conversion.
- Live Visitor Intelligence: Watch real-time visitor activity to identify who is likely to buy and use the API for instant action.
Pricing starts at $9/month for up to 10k monthly events, and all plans include unlimited websites and team members. The tracking script is lightweight (4kb) and the tool is GDPR compliant. It also offers integrations for tracking product updates via GitHub commits and social buzz via đť•Ź (Twitter) mentions.
