Toffer Winslow
Toffer Winslow is the CEO and a board member of Diffblue, an Oxford-spun AI company that uses reinforcement learning - not large language models - to automatically write unit tests for Java code, at a pace of roughly one test every two seconds. A three-decade enterprise-software operator, he has run go-to-market and led companies through the growth-and-exit cycle at Dynatrace, RSA Security, Lavastorm, Tamr, and StackState (which he steered into an acquisition by SUSE). At Diffblue he is selling deterministic, on-premises AI to some of the most security-anxious buyers on earth: four of the ten largest U.S. banks, plus Citi, ING, Cisco, AstraZeneca, and BNY Mellon.
Howard Ting
Howard Ting is the CEO of Opal Security, a San Francisco identity-security company building a unified control plane for access governance. He took the top job in November 2025 after more than five years running Cyberhaven and two-plus decades scaling category-defining security and enterprise-software companies including Palo Alto Networks, Nutanix, Redis, Zscaler, and RSA Security. A marketing-and-product operator who once demoed Azure Active Directory on stage with Bill Gates, Ting now bets that the hardest unsolved problem in security is authorization: deciding what any human, service, or AI agent should be allowed to do, and for how long.
