Bitcoin-focused financial services company River secured $35 million in a Series B funding round, the company announced on Sept. 28 1. Kingsway Capital led the equity investment, with participation from Peter Thiel, Goldcrest, Cygni, M13, Valor Equity Partners, Esas Ventures, and Alarko Ventures 1.
River provides an array of $BTC services spanning brokerage accounts with zero-fee recurring purchases, mining services, full-reserve custody, and on-chain as well as Lightning Network wallet functionality 1. Alex Leishman, chief executive officer of River, stated that the interest driving the company's recent momentum stems primarily from enterprise and institutional participants seeking alternatives to conventional banking models 1. At the time of writing, Bitcoin was trading at $83,860, down 0.7% over the previous 24 hours.
Expanding Lightning Infrastructure
The company plans to allocate a portion of the capital toward growing River Lightning, its enterprise application programming interface (API) tailored for corporate integration with the Lightning Network 1.

According to River, transaction volume on the Layer 2 network has expanded markedly over the past year, spurred higher in recent weeks by rising on-chain transaction fees 1. Moving forward, the startup aims to position its enterprise infrastructure as a primary backend payment processor for third-party crypto platforms and financial applications 1.
