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.

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 $XXm from a group of investors including Y Combinator, an early investor in companies like Coinbase, Reddit and Monzo.
