About Klar
We're turning one of the world's largest underbanked markets into something fairer, simpler, and more transparent. 7 million users served since 2019. Uber's first global credit card, built right here in Mexico. Klar Empresarial, a brand-new B2B solution bringing agile credit and smart accounts to SMEs who've been ignored by traditional banks for too long.
And a full banking license on the horizon, because our customers asked for it and we listened.
We move fast, we think big, and we go all in, because as our CEO puts it: "Growing doesn't always mean going further. Sometimes it means going deeper."
Behind all of it is a team of 30+ nationalities, working across Mexico City, Berlin, and Argentina, obsessed with building financial products that are simpler, faster, and fairer than anything that came before.
This is Klar, and we're seeking the people who'll write the next chapter.
