CyberBank

CyberBank

Simonyi founded CyberBank to manage capital generated across a multi-decade career at the center of personal computing and software development tools. The wealth originates from his early work at Xerox PARC and Microsoft, where he oversaw the creation of Word and Excel, combined with the 2017 sale of his later venture Intentional Software to Microsoft. His spouse Lisa Persdotter is also associated with the office. The office pursues a concentrated, technically informed portfolio spanning early-stage enterprise software, space technology, and select real assets. Simonyi brings a computer scientist's lens to underwriting, often evaluating deal memoranda against his own standards for code quality and system architecture. Known positions include participation in space infrastructure ventures consistent with his longtime involvement in civilian spaceflight — he flew to the International Space Station in 2007 and 2009 aboard Soyuz rockets. The real asset portfolio is anchored by trophy residential properties, including a Swedish estate purchased for the equivalent of $70 million in 2021 and a Manhattan apartment at 1040 Fifth Avenue. CyberBank operates with a lean, family-centric structure that reflects Simonyi's preference for direct engagement over institutional layers. The team is small, centered on the principal and his immediate circle, with external legal and tax counsel engaged on a transactional basis. Philanthropic activity flows through the Charles and Lisa Simonyi Fund for Arts and Sciences, which has made eight-figure gifts to institutions including the University of Washington and the Seattle Symphony, and through direct donations such as a $100 million commitment to the Institute for Advanced Study in Princeton in 2024. The office's defining structural feature is its operator-as-allocator model — a founder who built foundational software tools now deploying capital using the same analytical framework he applied to code reviews. No institutional investment committee filters the pipeline; Simonyi personally evaluates opportunities through a lens shaped by decades of pattern recognition at the frontier of software development.
