If you are wondering how Stripe could even start with just 7 lines of code, it's a bit misleading:

  With Stripe, all a startup had to do was add seven lines of code to its site to handle payments: What once took weeks was now a cut-and-paste job.

I.E. the simplicity of the Stripe platform (taking only 7 lines of code for developers) was how they succeeded, not that they built a startup at first with just 7 lines of code.
