We give brokers, exchanges, and fintechs direct access to U.S. stocks, ETFs, and options.
One gateway to
the world's markets
Give your users access to the deepest, most liquid capital markets in the world — equities, ETFs, and listed options — through a single counterparty that handles execution, clearing, and compliance. Starting with the U.S. and expanding across Asia.
Global Equities
Full access to U.S. (NYSE · Nasdaq) and Hong Kong listed equities — with fractional, dollar-based trading down to the cent. Japan & Korea coming soon.
ETFs
Thousands of exchange-traded funds for diversified, low-cost exposure across sectors, themes, and indices.
Options
Wall-Street options strategies brought to retail — with fractional, sub-100-lot execution previously out of reach.
Institutional-grade execution,
delivered as infrastructure
Connect once and inherit a fully managed brokerage stack. We absorb the complexity of clearing, settlement, inventory, and compliance so your team can focus on your product.

Our platform handles seamless connectivity with clearing firms and brokerages. We handle all inventory risk and setup, with a streamlined integration process that gets you live faster.
