Marc Lou — Product Hunt Maker of the Year 2023
Hey,Explorerfrom Earth 🌍

I'm Marc, the creator of DataFast. I've also built 24 startups and earned $2M+ online.

I learned that data is a goldmine of opportunities. But most analytics tools just show vanity metrics...

Pageviews, visitors, bounce rates... but do any of these actually tell you where your money is coming from?

So I built DataFast for 3 reasons:

  • Find marketing channels that drive PAYING customers, not just pageviews.
  • Discover what makes people buy and turn more visits into revenue.
  • Make revenue-driven decisions and work on the right things.

I'm building DataFast in front of 127,000+ people on Twitter. Let's ship! 🧑‍💻

There's basically no need for PostHog anymore given how good this is and how little effort it is to attribute revenue to marketing efforts.
