It looks like Sarah got paid by Stripe and Braintree. In my opinion she writes what she was told to write having not knowledge about particular business (regardless her previous achievments). Moreover looking at TechWorld in Europe and Asia nobody heard about her and her company. In her article she talks about the bigest and strongest company (PayPal) in the world which does not have many competitors (especially those two above :-)). Stripe and Braintree are only a few drops in PayPal ocean. All of this info is bullshit and both companies mentioned above are not even close to PayPal, it is so funny she compares 8 months old company with 2000 businesses to the global giant like PayPal ( It is even not professional). It is like comparing national social networks to global Facebook. And remember PayPal is investing millions in innovations every year to keep their business on the top and provide the best customer satisfaction.
