How Mangopay helps startups scale

Mangopay was able to scale thanks to the concept of the FlyWheel. It is a mechanical part present in windmills or in tractors. It’s hard to start, but once it gains speed, it accelerates by itself. Every entrepreneur has a Flywheel. Every startup should know its own. Mangopay’s Flywheel goes through 4 stages :

  • Connecting with contractors
  • Knowing their needs
  • Create their solution
  • Industrialize the solution on a larger scale

It sounds simple, but each step takes time and internal work to make this process automatic. This principle is important to scale because it is the creation of value that is self-sustaining. There is a real notion of industrialization. You have to set up a system that generates value by itself.

As a credential, Romain takes the example of Vinted, which they have accompanied from their beginning, until their maturation. They helped them to grow their solution from being limited to Lithuania to becoming international. Crowdfunding platforms also trust them to benefit from this FlyWheel By Mangopay. This is also the case of Ulule and KissKIssBankBank.


The solution to scaling seems simple. It is the concept of the Flywheel. However it is not so easy to apply. It is an investment on each step and a follow-up to have. This principle was not invented by Mangopay but is something that can be found in other companies like Amazon. So get closer to Mangopay, to know all the secrets of this method.
