Advisory Council Additions Mark Strategic Push for YC-Backed Oximy
Oximy, a San Francisco-based platform specializing in AI governance and value measurement, announced the appointment of four prominent technology veterans to its Advisory Council on October 8, 2026. The new council members include former executives from Oracle, Cox, Notion, and Twitter, bringing decades of enterprise IT, security, and engineering experience to the Winter 2026 Y Combinator batch member.
Veteran Tech Leaders Join Oximy’s Advisory Board
The newly formed council consists of Mark Sunday, Greg Morrison, Patti Degnan, and Adam Messinger. These advisors will guide Oximy on product direction and enterprise adoption as organizations grapple with internal AI governance and data security.
Mark Sunday brings 13 years of experience as CIO of Oracle, where he managed global IT and security operations. Greg Morrison served for 18 years as SVP and Corporate CIO of Cox Enterprises, overseeing core cybersecurity and technology strategy.
Patti Degnan contributes expertise from her roles as CISO/CIO at Glow and Notion. During her tenure at Notion, she scaled the security and IT functions from a single individual to a 60-person team while the platform expanded past 100 million users and 1,300 employees. Adam Messinger rounds out the group, having previously served as CTO of Twitter—where he directed product development and design—and as a leader for Oracle’s Java and Exalogic teams.
Oximy Evaluates AI Requests Against Internal Company Policy
Oximy operates by evaluating AI requests, uploaded files, and autonomous agent actions directly against internal company policy before execution. Depending on predetermined parameters, the platform can authorize an action, issue a warning, redact sensitive information, trigger a manual review, or block the request entirely.
“As CIO at Oracle, I saw firsthand how difficult it can be to understand how technology is being used across an enterprise, whether it’s delivering the expected value, and how to govern it effectively,” Mark Sunday said regarding his appointment. He added that if he were currently sitting in the CIO seat, he would evaluate the platform closely.
“CIOs are being asked to explain their AI investments to CEOs and boards, and that responsibility is difficult to delegate,” Morrison stated, noting that Oximy targets a core operational issue for enterprise leadership.
Backing and Venture Support in San Francisco
Headquartered in San Francisco, Oximy emerged from Y Combinator’s Winter 2026 batch. The platform is backed by a syndicate of investors including Y Combinator, Seven Stars, Peak XV Partners, Schema Ventures, Blume Ventures, SF1, Timeless Ventures, and Gokul Rajaram.
“Enterprise leaders need to decide which AI tools, workflows and agents to approve, where to invest and when to intervene,” said Naman Ambavi, founder and CEO of Oximy. “Our advisors have led technology and security inside large organizations. Their experience will help us stay focused on what matters to customers: making AI useful, protecting the business and understanding its value.”
