Jason has spent his entire career contributing to some of Silicon Valley’s most impactful technology companies.

After first earning an Engineering degree at the University of Colorado, he joined PayPal as employee number 34 while still a graduate student at Stanford University. As a Vice President on PayPal’s Finance team, he helped support the company through its hyper-growth, Initial Public Offering and subsequent $1.5bn acquisition by eBay in 2002.

Jason next gained privileged insight into the formation and rapid growth of two highly influential asset management firms. He was part of the founding team of Clarium Capital, which grew to over $3bn under management during his tenure. He later helped launch the Founders Fund whose early investments included Facebook and Palantir Technologies.

Operationally, Jason acquired senior leadership experience at two pioneering software companies in Silicon Valley. He was the first Chief Financial Officer at Palantir Technologies and later served that same role at Practice Fusion. In both cases, Jason helped guide the company’s early culture, fundraising strategies and industry leadership positioning.

Along the way, Jason’s innate curiosity lead him to Angel investments in several ground-breaking companies including Facebook, Palantir Technologies and Stemcentrix.  He continued to hone his investment philosophies through Subtraction Capital, a boutique Venture Capital firm he founded in 2012 which later evolved into Oakhouse Partners.

Today, Jason applies his many years of experience through the framework of Oakhouse Partners, a firm whose mission underscores his deep commitment to discovering and supporting talented entrepreneurs pursuing important challenges.
