Founded on a great idea

PEAK6 Investments, L.P. was created from the same ambitious, entrepreneurial culture that thrives in the firm today. Co-founders Matt Hulsizer and Jenny Just started their careers at O’Connor and Associates — a Chicago-based options trading firm with a particular specialty, and emphasis, on financial derivatives. In 1992, the firm was acquired by Swiss Bank Corporation. After the acquisition, Swiss Bank decided to head in a new direction.

Entrepreneurs at heart, Matt and Jenny wanted to bring a different vision to life and decided to launch their own firm. And in 1997, PEAK6 Investments was launched. PEAK6 Investments became one of the first firms to develop sophisticated, proprietary technology, which more efficiently manages risk in the options market. This disciplined focus on risk management and technology has helped us achieve significant success in managing risk and making markets. From this singular focus, the firm continued to innovate, growing PEAK6 into a diverse group of thriving, successful businesses that now span many areas of the financial services sector.

In 2006, PEAK6 launched two new businesses, looking to reach an entirely different set of investors. PEAK6 launched OptionsHouse — an online, consumer retail brokerage that delivered an exceptional combination of value and technology for active options traders. PEAK6 also launched PEAK6 Advisors, LLC — an SEC-registered investment adviser.

Then, in 2012, PEAK6 expanded its operational expertise into the clearing business with an investment into Apex Clearing Corporation. By combining decades of experience in clearing and execution with PEAK6’s innovative approach to risk management and sophisticated technology solutions, Apex established itself as a leading provider of clearing and execution solutions to the financial services industry.

After building OptionsHouse into a thriving online brokerage, PEAK6 sold OptionsHouse to General Atlantic, a well-established global growth investor. Also this year, after growing PEAK6 Advisors’ assets under management to over $2 billion, PEAK6 sold its stake in Advisors to Joe Scoby, former CEO of PEAK6 Advisors.

Today timeline_arrow_3

Today, PEAK6 remains anything but your typical investment firm. Every day, our culture motivates us to seek out, and invest in, good ideas that have the potential of becoming great businesses. We’re always looking for ways to deliver untapped, exceptional value to the market.

Our values

Our culture isn’t for everyone. We don’t have a laundry list of fluffy values that sound good but no one really gets. It’s a short, focused list and embodies our essence. We live and breathe these values across the entire firm. In a nutshell, we hire, fire, and promote through this lens.

Our Culture

We believe you should enjoy coming to work. Which is why we work hard to make PEAK6 a great place to work.

We provide good flexibility in terms of work-life balance, an open and candid atmosphere, and development potential as the company continues to grow. It’s the kind of place where you can really develop your career, while working in a great space, surrounded by friendly people, and learning new things daily. See for yourself why it’s a great place to come to work.




Why the name “PEAK6”?

Not surprisingly, the story behind the PEAK6 name began in the mountains. Matt was in Breckenridge, Colorado and inspiration struck. He recalled someone once telling him it takes 6 peaks to make a mountain range. He was drawn to this notion of peaks and how they can stand alone and/or work together to form something even more powerful. This perfectly represented the vision for the new firm. And with that, the PEAK6 name took hold. Interestingly, the peak that Matt used as inspiration for our name so many years ago opened to the public in 2013. They named it Peak6. And no — we had nothing to do with it. It’s just fate working its magic.
