Sourced startup case studies: how companies like Canva and Cursor grew so fast, why others failed, and what founders can copy, with free data downloads.
Everyone quotes 15-20% a month, 5-7% a week, or T2D3, and rarely says where it came from or what it measured. Here are five benchmarks, each traced to its original source and put on the same monthly basis.
Every few months a startup announces it is the fastest ever to $100M ARR. They are rarely measuring the same thing. Here are nine claims, each traced to the company's own words, with the starting line and the metric spelled out.
Afterpay processed A$0.27 million of sales in June 2015. Six years later Square agreed to buy it for US$29 billion in stock, and by closing day those shares were worth US$13.9 billion. Here is how it grew, from its own ASX filings and Block's SEC documents.
Stripe launched publicly in September 2011 with about 100 users. In 2025, businesses on Stripe processed $1.9 trillion. Here is what moved the curve, in the Collisons' own words and Stripe's own numbers.
