About Us

At Félix [https://felixpago.com/], we're building the financial ecosystem for

Latin immigrants in the U.S., starting with a revolution in remittances. Our

core product is an AI-powered chatbot built on WhatsApp, allowing our users to

send money home as easily as sending a text message. We leverage cutting-edge

technology like AI, blockchain, and stablecoins to make cross-border payments

faster, more affordable, and more accessible than ever before.

We are a hyper-growth Series B company, backed by over $100 million in funding

from top-tier global investors, including QED, Castle Island, Switch Ventures,

HTwenty, Monashees, and General Catalyst Customer Value Fund. This isn't just

about the numbers; it's a testament to the trust our investors have in our

vision and our team. Additionally, Félix was selected as an “Endeavour

Entrepreneur” and was a recipient of the CrossTech Fintech Startups Award. We

are a group of extremely talented and dedicated high-performers, united by our

shared obsession with a single goal: empowering our customers. We are all owners

of Félix, driven by a bias for action and a true experimentation spirit to get

shit done with urgency and focus.

we care less about what others are doing, and more about creating sustainable

value and a product that truly makes our users' lives better. We are building

the future, today.
