Comment highlights
Great idea. I’m almost ready to buy, but I have a question: how is the channel determined? For example, if I buy ads from different YouTube bloggers, will the service show them together as a single YouTube channel?
hello @marclou , Are you offering any discount codes for the PH launch?
This is a great reminder that clarity beats scale early on. Building for a real, lived problem and staying close to revenue instead of vanity metrics is what creates durable products. The patience to keep shipping while the market catches up is underrated, congrats on sticking with it and letting focus do the work.
Switched from Plausible to DataFast in their early days, never looked back.
Congrats on launch!
How customizable are these dashboards? Will it also present data from clarity/hotjar or google tag manager?
Competing with giants and still sticking it out takes real conviction. Congrats on turning a “nobody cared” idea into something meaningful.
Hey Marc, this product looks really solid! I've been struggling to connect click data with actual revenue, and seeing Stripe integrated directly with traffic analytics perfectly addresses my need for data transparency.
Quick technical question: how do you handle multi-touch attribution models and data adjustments for refund scenarios? These are often critical to ensuring data accuracy.
Already bookmarked the product link—planning to integrate and test it with our team’s SaaS project this weekend. The design is clean and practical, with no unnecessary features—exactly the kind of tool engineering teams appreciate. Looking forward to seeing the results!
I was using analytics for a decade and was wondering what for. Now i know why i look to the chart !
It will be the best choice for founders who is making revenue!
But I can't use this because i'm a early founder who has a product making no revenue.
Actually so i'm building a service to build initial marketing campaigns for people like me.
As the campaign progresses, it will let them know what they should do to grow it up.
I hope i will launch it soon and you would see it.
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?
Interesting product I’m curious — how do you compare this with existing solutions in the market? Congrats on the launch
Keep up the great work @marclou! You've inspired me a ton over the past few years 🙌

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!
