About Klar

Klar is on a mission to democratize financial services in Mexico—because half of the population still doesn’t have access to a bank account. We’re building the future of fintech with a rich set of debit and credit products, and we’ve already served over 2 million users since our launch in 2019! 🚀 

We are now entering the business segment, and our goal is to provide the best financial operating system for small and medium-sized enterprises (SMEs). 

We are also proud to have been certified in 2023 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 to 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 (young professionals, parents, LGBTQ+, neurodivergence), you’ll definitely find your people here! 

Our values

Ownership - We own our successes & our failures as a team.

Excellence - We do everything to the best of our ability & always seek to achieve a new level of excellence in our work.

Inclusion - We believe we are stronger together and actively work to promote a safe, diverse, inclusive, and respectful culture.

Customer Obsession - We understand the value Klar can bring to its customers & it’s always at the forefront of our decisions.

Klarity - We communicate clearly & with authenticity. It’s in our name & it’s what we do.
