5. What we believe in?

We believe in the three C’s. Three, because people can’t remember four, and two is not a list! ;-).  

The three C’s are fundamental to how we operate, both internally and externally. We always ask ourselves three questions, what do we commit to? how are going to collaborate in this? And once we have achieved this, how are we going to celebrate this? 

Here is an external example. We have a new customer. We commit ourselves to onboard the customer in less than 3 months, we collaborate with the customer, which means OneWelcome needs to do things and the customer needs to do things, both need to deliver, to ensure the commitment. And upfront we define how we are going to celebrate this together, “press release, diner after go live, etc.”. 

Here is an example.  Our company has a growth challenge. We want to onboard customers for a new innovative proposition in less than 1 month. We commit ourselves to realise this, we have departments such as Engineering (adjust the product) and Professional service (standardize the onboarding), and Sales (prepare sales material) work together on this. And upfront we decide we will go wake boarding and have a BBQ afterwards to celebrate the success once accomplished.


OneWelcome is European's number one Identity platform by:

  • Providing the Richest product offering
  • Empowering enterprises to provide Europeans safe and simple access to online services
  • Collaborating with European partners

OneWelcome currently is the largest European CIAM and B2B SAAS vendor. We secure over 100 large enterprises, such as the European central bank, Aegon, Essent, Dutch Railways, Malakoff, PostNL, ASR, Damen and many more. Also, we secure more than 80% of the Business 2 government traffic in our local market.

Our vision is centred around connecting and protecting people, businesses, and things. We believe in creating optimal balance between ease-of-use and safety in the user-journey. No matter if it is for a day, a full lifetime, just temporary or occasionally. Who the user is, what the user is allowed to do, enabling the user to opt in or out defines the relationship and its governance. Identity management is the basis of every online interaction and a true precondition in the implementation of any digital strategy.
