6sense has announced two major leadership appointments to support its next phase of AI-driven growth. Ashley Jefferson joins the firm as Chief People Officer, bringing over 25 years of HR leadership from companies including Synoptek and Rackspace Technology. Jefferson’s mandate is to scale the company’s global talent strategy, focusing on performance systems and "AI readiness" for the 6sense workforce.
Simultaneously, the company has promoted Julia Lake to the newly created role of Chief Information Security Officer (CISO). Lake, who previously led security assurance at GitLab through its IPO, has spent the last three years building 6sense’s security infrastructure from the inside.
The dual appointments reflect a strategic pivot toward balancing rapid AI innovation with enterprise-grade stability and trust. As CISO, Lake will oversee global security operations and risk governance, ensuring that data privacy and AI security are embedded into the platform’s architecture rather than treated as compliance checkboxes. According to CEO Chris Ball, these moves are foundational to the company's "Signalverse" network, which captures trillions of buyer signals to orchestrate personalized B2B engagement.
