It sells a cloud-native platform that combines trading, risk management, financing, clearing and custody, and connects to banks, clearing houses, depositories, brokers and exchanges. Customers are institutional and sophisticated investors, with about 3,800 clients. Revenue comes mainly from net financing on customer margin and short balances, plus commissions, clearing fees and investment banking. Its IPO filing showed $783.7M revenue and $157.2M net income for the first nine months of 2025. A Series B-1 in 2024 reportedly valued it at about $2.1B. A Series C in January 2026 reportedly valued it near $12B. It filed to list on Nasdaq as CLRS, then cancelled the IPO in February 2026 after cutting the target.
