Bree Giannelli is a go-to-market enablement leader who builds functions from the ground up. She started in sales at iMatrix, working from account executive to managing the vertical, then moved into leadership enablement at Better Mortgage, where she built onboarding and continued education for managers, directors, and above. After leading enablement for government sales at LeoLabs, she joined Second Nature as its first enablement hire and grew the function into a five-person team spanning sales, implementation, CX, and customer enablement. There she launched a company-wide onboarding program that ran 120+ new hires through it, owned the enablement platform from procurement through adoption, and was a key stakeholder in the go-to-market rollout of a $75 million strategic partnership. She is now Head of Sales Enablement at Tango Analytics. Bree believes enablement earns its seat at the table through strategic alignment and business understanding, not by producing more training.
