The Wisconsin native is the biggest individual owner of Class B shares of Seattle-based Tableau, which makes analytics software that converts data into easy-to-understand charts and other graphics. On Monday, Salesforce.com Inc. agreed to buy Tableau in an all-stock deal valued at $15.3 billion.
Hanrahan owns 6.9 million of Tableau’s Class B shares, which have the same economic value as its traded A shares but with 10 times the voting rights. The value of his stake soared to $1.15 billion at 10:15 a.m., a third higher than at Friday’s close.
Hanrahan didn’t immediately respond to a request for comment, nor did a spokesman for Tableau.
Tableau sprung from a research project at Stanford, where Hanrahan is a professor of computer graphics. With former PhD student Christopher Stolte and venture capitalist Christian Chabot, Hanrahan spun it out as a separate business in 2003 and went public a decade later.
An early employee at Pixar, Hanrahan worked on “Toy Story,” among other films, and won Oscars for technical achievement. While at the animation studios, he was chief architect of a design software called RenderMan Interface that describes three-dimensional scenes and turns them into digital photorealistic images.
Despite Tableau’s success, Hanrahan’s roots are still firmly in academia. The billionaire’s primary gig remains his teaching role at Stanford’s school of engineering. He dedicates about 20% of his time to Tableau, where he’s a part-time employee, according to the latest proxy filing.
