Marcus Ryu has been named a general partner at Battery Ventures.
Ryu co-founded insurance technology leader Guidewire Software in 2001 and served as its CEO through its IPO in 2012 until 2019. Guidewire today has annual revenues of more than $1.2 billion and a market capitalization of nearly $20 billion, as of this month. Since joining Battery in 2022, Ryu has focused on investing in vertical enterprise-application and AI companies, as well as financial and insurance technology.
“Co-founding and leading my company for almost two decades was the defining experience of my career. It is deeply rewarding for me to advise and learn from entrepreneurs in today’s startup environment, which is much more supportive of founders than mine was but is also more competitive on every dimension,” said Ryu. “It is a privilege to join the general partnership at Battery, whose combination of fundamental market analysis and founder-first values makes it the ideal professional home for me in this era.”
Ryu’s investments at Battery include AI-powered, video-security company Coram AI; hyperexponential, a U.K.-based firm providing an AI-powered pricing and underwriting platform for insurers and re-insurers; Descartes Underwriting, a provider of parametric insurance for natural catastrophe and emerging risks; and Fairmatic, a provider of AI-powered insurance for vehicle fleets.
Previously, Ryu served on the boards of technology companies MuleSoft, Opower, Clearwater Analytics, Cornerstone OnDemand and Procore Technologies, as well as serving as Guidewire’s chairman. He holds an A.B. from Princeton University with highest honors and has a B.Phil. in philosophy from New College, Oxford University, which he attended as a Marshall Scholar.
"Very few investors have traversed the entire journey from founder to IPO to public-company CEO, which affords Marcus a unique combination of commercial instincts and founder empathy,” said Battery General Partner Neeraj Agrawal. “Founders gravitate to him because he understands the intellectual and emotional demands of building a start-up into a hugely successful enterprise. Battery was fortunate to be an investor in Guidewire and see Marcus' skills in action first-hand, and now we're extremely enthusiastic to promote him to general partner. He is sure to be an inspiring influence on the next generation of entrepreneurs backed by Battery."
