DataFast Surpasses $17K MRR

Marc Lou's DataFast has reached a significant milestone of $17K MRR after 16 months of growth. The product, which connects Stripe to traffic analytics, has gained traction primarily through word of mouth.

January 28, 2026$2K ARR Milestone

Original Announcement

483 days ago, I built my own web analytics out of frustration.

I was using Plausible and loved its simplicity, but I felt stuck. Pageviews are nice, but they don’t tell you what makes money.

So I built my dream tool: connect Stripe to traffic, and see where revenue actually comes from, so I can double down.

Almost nobody cared.
It took 120 days to reach $1k MRR.

But I didn't mind. I was having fun.
I shipped 117,869 lines of code to build features I needed myself.
My only KPI was (and still is) features shipped.

Slowly, word of mouth kicked in, and the SaaS started growing on its own.

16 months later:

- $17K MRR
- 983 paying customers
- 1.2B pageviews tracked

I wanted to quit many times. I’m competing with giants and VC-backed startups, in an overcrowded market, for a vitamin product.

What changed everything was niching down: building ultra-specific features for my own problems and hoping others had the same ones.

I don’t really do marketing. Most users come from word of mouth.

But today is special. I never truly launched @DataFast_, so I made this video to finally do it. Hope you like it!
