Julia Lake named Chief Information Security Officer at 6sense

6sense, the revenue intelligence platform, announced on April 16, 2026 that it has promoted Julia Lake to Chief Information Security Officer, alongside the appointment of a new Chief People Officer.

Promoting from inside to the CISO seat at a SaaS company selling AI agents to go-to-market teams puts continuity first, at a point when customers are scrutinising how their data flows through those agents.

According to the release, Lake leads the global security and trust strategy at 6sense, covering compliance, security operations, third-party risk management, AI security and risk governance, and cloud and application security. The company says her work is meant to embed security into the way 6sense builds, operates and scales its AI-driven platform. The release says Lake works with teams across the company on the responsible use of AI, so that governance, risk management and transparency keep pace with its growing capabilities.

Before joining 6sense, Lake held senior security roles at GitLab, where she led Security Assurance through the October 2021 IPO of the globally distributed, publicly traded DevOps platform, the release says. At the DevOps platform, she worked closely with product and engineering teams to align privacy, compliance and security with rapid innovation and a remote-first operating model, the leadership page says.

The company says 6sense captures trillions of buyer signals, which it uses to orchestrate personalized engagement, prioritize contacts and uncover in-market accounts. According to the release, AI Agents on its single connected platform automate manual tasks across marketing and sales.
