## How Markets Should Be
Traditional financial markets are broken. We are fixing them.
QFEX is the first perpetual futures exchange to allow 24/7, high leverage on traditional financial assets.
Our vision: this kind of exchange will replace the entire $100bn TradFi exchange, clearing and brokerage industry
Our mission: make QFEX that exchange.
We were founded by Cambridge Maths duo Annanay Kapila and Joshua Wharton, who previously worked at Tower Research Capital and Citadel, respectively. The team also includes former staff from Jump, Barclays, and more.
QFEX raised $9.5m from a group of investors including General Catalyst, Y Combinator, Nexus Venture Partners and Paul Graham.
