01/The verdict
A $9 to $29 per month MRR, churn and revenue-attribution dashboard for small SaaS founders billing through Stripe, Paddle, Lemon Squeezy, Polar, Creem or Freemius.
Chartsy reads public billing APIs that anyone can call with a self-serve key. It calculates standard SaaS metrics and adds a tracking script for channel attribution, and Claude Code can rebuild all of that in a couple of weeks. It has 6 active subscriptions, $99 MRR, $909 all-time revenue (a one-off $414 August spike that likely came from an AppSumo listing), a founder with 557 X followers and a DR 28 domain, so there is no audience, data or lock-in to protect it. The market is crowded: free Stripe and Paddle dashboards, ChartMogul, Baremetrics and DataFast.
02/1 moat
Shallow
It supports seven billing sources: Stripe, Paddle Billing, Paddle Classic, Lemon Squeezy, Polar, Creem and Freemius. That includes Freemius-specific handling so lifetime licences don't inflate MRR. All of these are public self-serve APIs, and none needs partner approval.
To cross it: Write a connector for each billing API, roughly a few days each with AI tools, and copy how Chartsy normalizes lifetime and annual plans.
03/The gap
Easy to copy
- MRR, ARR, churn, LTV and plan breakdown math from billing data, which every competitor already shows
- A first-party tracking script that ties visits to signups and payments, the exact feature DataFast and others already sell
- Natural-language questions and an MCP server on top of billing data, both thin LLM layers
- Comparison and SEO blog pages like 'ProfitWell alternative' and 'best subscription analytics', which any newcomer can write
How you'd go after it
- Bundle MRR dashboards into an existing analytics or attribution tool that indie founders already pay for (the DataFast playbook), so Chartsy becomes a redundant second bill
- Offer a free tier for founders under $1k MRR, where Chartsy's 6 customers sit and $9 is a real cost
- Grow from a founder audience on X or YouTube; Serena has 557 followers, so a creator with 20k+ wins the indie hacker channel
- Go deep on one underserved billing platform, such as Freemius WordPress plugin makers or Dodo Payments, and own its SEO and community
04/Build against it?
Stay away
Billing platforms give these metrics away free, established tools cover the high end, and revenue-first attribution tools with big founder audiences already own the indie end. Chartsy's $99 MRR after 20 months shows how little room is left. Only worth it if you already have a large indie-founder audience to sell to.
