About KLAR
Let’s start with the basics! Klar is a Mexican fintech startup whose mission is to democratize and revolutionize the way in which financial services have been delivered so far in Mexico, especially since half of the population doesn’t have a bank account. We offer a rich set of products across our debit and credit offers and the future is bright for Klar! We have an exciting and ambitious roadmap to bring more features to our products so that we can better serve our users. We have served more than 2 million users since our launch in 2019!
We are also proud to have been certified as a “Great Place to Work” in Mexico - we’ve worked hard to make that happen and will continue to make bigger strides in the future! Sound like a place you’d like to be?
Our people
If you join us at Klar, you’ll be welcomed into a team which is rich in many talents and we are very proud! With our head office in Mexico City, and remote tech hubs in Berlin and Argentina, we are always learning something new about another culture or language. With so many people from different backgrounds and walks of life (parents, LGBTQ+, neurodivergence), you’ll definitely find your people here!
