Copy trading & AutoTrade
Strategy subscriptions, signal delivery and automated execution into the investor's own broker account, with explicit consent and an instant stop.
OverviewTraditional Markets
Beyond crypto
Trading on regulated markets raises the bar: every order lands in a real brokerage account, every number on screen is a promise to an investor, and nothing can be faked, guessed or shown as zero when the data simply is not there. We build investment products around that discipline.
Quantara Capital is a copy-trading platform we designed and engineered for US investors. They screen 1,000+ strategies on 57 metrics each, practise on virtual capital, subscribe to signals and connect their own broker account — Interactive Brokers and others — to run AutoTrade. It went from first scope in May 2026 to production in October 2026.
Whether you are launching a branded copy-trading service, a strategy marketplace or a trading app on top of a broker or signal network, we cover product strategy, UX, full-stack engineering, broker and data integrations, billing and DevOps.
