Salary benchmarks

Our take

Circle is a financial technology firm looking to enable businesses to harness the power of digital currencies and public blockchains for payments, commerce, and financial applications. The company’s USD Coin (USDC) has become the fastest growing, regulated, and fully reserved dollar digital currency.

The company is backed by the world’s largest asset manager, BlackRock, as well as crypto exchange company Coinbase, and has been proactively preparing for possible upcoming federal regulations. Regardless of the current crypto downturn, this means that Circle is still well-placed to see steady long-term growth.
