Thinkers Risk Takers Innovators

Our Origin Story
In the early nineties, Jenny Just and Matt Hulsizer worked for a well-known trading firm in Chicago, O’Connor and Associates. In their mid-twenties, they were both selected to work on an over-the-counter equity derivative business for a pivotal Swiss Bank and O’Connor partnership. They were fortunate enough to work alongside the legendary Clay Struve, one of the best risk managers in the world, where they learned the invaluable lessons that shaped their savvy outlooks to this day.

Eventually, O’Connor and Associates moved the business to the East Coast. Chicagoans through and through, Jenny and Matt were determined to stay. They pitched the executive team on opening a new line of business, which, of course, would be based in Chicago. They received a resounding no. Jenny and Matt looked at each other and uttered the phrase that would define their trajectory into entrepreneurship, “There’s a better way.” They left O'Connor and Associates soon after.
The Shared Vision
Early on, the duos' ideas percolated on what they were going to do. Fear didn’t factor into their decision. They weren’t surrounded by the ubiquitous stories of failure everyone sees today.

PEAK6 started as a proprietary equity options trading firm — and still operates that way 25+ years later. Their original vision didn’t include the powerhouse of a holding company PEAK6 has become. Jenny and Matt built a team. Money made from the trading business fueled PEAK6’s other ventures.

From a chicken-cleaning business to a ferris wheel to an oil field, some of Jenny and Matt's ventures didn't come to fruition, but they learned from each decision. Concurrently, the markets started to change. PEAK6 built a hedge fund and a retail broker-dealer, OptionsHouse.
The Defining Moment
The pivotal point came in the form of a phone call from the CEO of Penson Financial Services, the custodian and clearing firm for OptionsHouse. Penson was operating at a significant loss and was teetering on the brink of bankruptcy. FINRA and the SEC were pushing for a sale and tens of millions of dollars were needed in the business within two weeks. The fate of OptionsHouse rested with Penson. Recognizing the opportunity before them, Jenny and Matt acquired what became Apex Fintech Solutions from Penson and saved OptionsHouse in the process.

The only goal: Anything that didn’t serve OptionsHouse had to go. Redundant employees were let go, as well as two-thirds of Penson's customers. At the same time, new technology was being developed: account-opening technology that would better serve PEAK6 and our OptionsHouse customers. This made us the only company with new technology that wasn't outdated and over 30 years old. Disruptive brokerage firms like Robinhood, Wealthfront, and Betterment soon signed on with PEAK6.

After that, PEAK6's identity changed. We became the technology company that enabled disruptors to disrupt.

We follow opportunities, not the status quo.
