Blockchain startups are getting more business opportunities now due to the increased interest of investors. In the second quarter of 2021, they raised a record $4.38 billion. This amount constitutes almost one-sixth of the total fintech investments for the period. The funding went up more than 50% from the previous quarter and illustrated a nearly ninefold increase from the same period a year earlier.

Some blockchain startups are developing quicker than others and have a promising future.


Circle Internet Financial was founded in 2013. It is a crypto finance company that seeks to make money more accessible through its products. The company offers various cryptocurrency solutions: Circle Invest, Circle Pay, Circle Trade, and Poloniex. Circle offers a P2P platform for individuals, institutions and entrepreneurs to use, trade, invest and raise capital with open crypto technologies, fast APIs, and the usage of AI. Circle also provides other commerce and financial applications for businesses. The company has insurance coverage for the crypto assets on its platform and stores a significant portion of customer funds offline.

Their institutional offering includes OTC desk, crypto exchange, and USDC stablecoin issued in collaboration with Coinbase. USDC is one of the top stablecoins on the market. It has supported about $700 billion in transactions over the past year. Its market cap has risen to $27B – more than a twofold increase since April. It’s the second most valuable stable crypto asset after USDT. The firm expects to have $190 billion of USDC in circulation by 2023 with a total transaction volume of $15 billion.

Circle recently announced plans to go public through a $4.5 billion merger with a blank-check company Concord Acquisition Corp. The combined entity is expected to debut on the New York Stock Exchange under the ticker CRCL before the end of the year. It’s an important step as there are growing legislative initiatives to regulate stablecoin trading and increase its transparency. However, many sceptics raise eyebrows at this alliance with a SPAC since many companies choose such ways to raise capital when they can’t withstand the heavy scrutiny of an IPO.

Generous investments are consistent with the incredible growth pace of the blockchain startup. Its ARR (annual recurring revenue) is up by 350% so far in 2021 compared to 2020.
