What We Do

PEAK6 is not your typical investment firm. Here, we build and invest in businesses that span from finance and insurance to esports and education — and we're always seeking new opportunities. We're not defined by one industry or market. We activate "what is" into "what ought to be" through world-class technology, operational excellence, and purposeful design.

We're in the business of doing, creating, and building the world with innovation and democratization in mind. Our team of opportunistic thinkers are generating new ideas while constantly improving, refining, and activating past ones. At PEAK6, it's not just our investments that make use great, but our people that make us valuable.

Why Work With Us

Ordinary doesn't apply here. We look for people who aren’t afraid to take chances, who bet on themselves and do it with confidence. People that dream up big ideas and ways to execute them. Epic storytellers, nimble problem solvers, imaginative entrepreneurs, and change-makers are all welcome.
