Hey Hunters, it's Marc!

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!

@marclouΒ THE best product introduction video I've seen. And I've seen a shit ton of them :) BEAUTIFUL.
Will be taking a tour and exploring features.
Just two questions (with Leo clapping his hands off in the background):
1- Pricing?
2- Do you get rid of Google Analaytics (GA4) completely or keep it and build on top of it? Say a Shopify Store.

3- Give me a totally random fact that I would find super interesting.

4- How does implementation (the 3 minutes) usually go? Code snippet installed on the CMS itself?

5- You win product video of the year, hands down mate. Hear that @Product Hunt ?

@marclouΒ This resonates a lot. Traffic metrics without revenue context can be misleading β€” tying Stripe events back to acquisition channels feels like the missing layer most analytics tools avoid. Curious what surprised you most once you saw the revenue data.

I switched from Google Analytics to DataFast.
Thought: Well, lets just try it out with the free tier but I will most likely stick to Google Analytics.
What else could DataFast offer which I dont get already included in GA?

BOY WAS I WRONG!

After using DataFast I will never ever use GA again.
My mind was blown when I saw, how cool, userfriendly and innovative a analytics tool can be.

Tracking goal, custom funnels, live maps, X (Twitter) integration and so so much more!
The best part? The setup literally takes only 5 minutes. That is not a marketing slogan, it is the truth.

Do yourself a favor, invest half an hour and $0 into getting dataFast setup, explore it and thank Marc later.

Feels sane. Tired of guessing which clicks pay rent. Stripe + traffic is exactly what I wanted Plausible to do. How do you handle multi-touch and refunds? Bookmarked to test on my tiny SaaS this weekend. Nice ship, Marc.

Congrats on the launch! The Stripe to traffic connection is a really clear way to move beyond vanity metrics. Once you started niching down, which specific revenue or behavior insight ended up changing how you actually built or prioritized features the most?

John Rush

clearly the best tool launched on here in 2026 (connecting revenue to traffic is a genius idea)

if it wont win, I'm removing product hunt from my bookmarks right away

Victor

I use it every day ! My tool to follow my data
