About Fiat Republic

Fiat Republic is a London-based remote-friendly fintech dedicated to bringing mainstream banking to the world of digital assets. Founded in 2021, the company has quickly established itself as a leading provider of banking and payment infrastructure for cryptocurrency companies.

Our Mission

Fiat Republic's mission is to bridge the gap between traditional finance and digital assets by providing cryptocurrency businesses with a single API to create bank accounts in multiple fiat currencies, access local bank payment rails, and manage FX and liquidity operations. We are a highly regulated business, with electronic money and money service business licenses in the UK, EU, US and Canada. We are also an issuer of MiCAR compliant stablecoins, with the distinction of being the first EMI in Europe with custody privileges. As such, we are perfectly placed to bridge the gap between tradFi and web3.

Our Platform

The Fiat Republic platform is built with a developer-first ethos, making it easy for crypto platforms to integrate with our services and start processing fiat payments. We also have a strong focus on AML, regulatory compliance, and security, ensuring that our clients can operate their fiat flows sustainably, safely and securely.

Our Team

Fiat Republic is a diverse team of outstanding individuals with a wide range of backgrounds and experiences. We are headquartered in London, with a presence in the Netherlands, Poland, Turkey and Canada. We are committed to providing our employees with a fun and thriving work environment, offering rapid skills development and the opportunity to learn about the payments and crypto industries.

Our Investors

Fiat Republic is backed by top-tier venture capital firms such as Speedinvest, Credo Ventures, Seedcamp, Fabric Ventures, Kraken Ventures, Arca, and Inovo Ventures. We are also alumni of the Softbank Emerge Accelerator program.

Our Impact

Fiat Republic is making a significant impact on the cryptocurrency industry. By providing crypto businesses with a simple and secure way to bank and process fiat payments, we are helping to drive the adoption of digital assets and making it easier for people to access the benefits of cryptocurrency.

Our Future

With the increasingly positive tailwinds in the cryptocurrency industry, Fiat Republic is poised for continued stellar growth. We are constantly expanding our platform and adding new features to meet the needs of our clients. We are also looking to expand our team and hire talented individuals who are passionate about banking, payments, cryptocurrency, and working in a fast-paced start-up environment.
