Now planning and mobility finally meet... Calendar42 that was founded by Michel Boerrigter and Jasper Hartong as a spin-off from TU Delft in 2011. These last few years we have developed a - as we like to call it - magical platform, that has the ability to connect the dots between people and resources. It can boost the productivity of any business by addressing on-demand planning and mobility topics. Today we employ over fifteen ambitious and enthusiastic team players, that help us achieve our ultimate goal: making lives truly easier.
We take that seriously, also for our employees. We have a nice office located at one of the prettiest canals in Delft. Here we enable our people to work hard and have lots of fun. Nice healthy lunches, silence rooms, chill spaces and team holidays are a part of our ambitious and pleasant culture.
We’d love to meet you.

At Calendar42 we have our core principles, a set of values we believe are important for all of our decisions.
We are human
We are moral human beings. We care, we listen, we are honest, we stay personal and we respect each other.
We respect privacy
A calendar is private property. Users should always be in control of their own data, and should have access to information about how their data is used.
We are open
We believe that sharing accelerates innovation. We use open technologies and open data to create value and translucency, this is one of our ways to give back.
We believe in social self-regulation
We believe in the self-regulating ability of a group. We (almost) never impose our opinions. We design & build tools for people and companies to express, communicate and plan the way they want to, but within our frame of vision.
We strive for relevance
Relevance is defined from the perspective of the user. It can only be achieved through being dynamic & content driven. We poses the power of data, and we see it as our responsibility to add value by offering the right information at the right time.
We are lean
We start small, test, adapt, scale up fast and deliver.
We are always on the move
Both personally and business wise. We keep developing, trying out new technologies, exploring opportunities and optimising the way we work.

Can you give me an idea of your standard method of working?
This of course depends on your job, but every (customer) journey needs a great story. A story we can divide into chapters, that become more and more exciting after every page in the book. How we manage this?
To help us control our future developments and ensuring our continuous evolvement, we have epic sessions in which we share our adventures.
How have you arranged the rules of the game of working as a team?
We have setup a social contract, they are a result of how we believe teamwork thrives best and basically boils down to:
On top of this, we as a team act based on these guidelines:
