Boler Davis spent 24 years at General Motors and in 2019 joined Amazon, where she led several e-commerce teams including Worldwide Fulfillment, Global Customer Service, and Global Robotics.
Founded in 2015, Alto is a full-service pharmacy that offers same-day prescription delivery. The company raised a $200 million Series E round led by SoftBank in January.
Boler-Davis will replace co-CEOs Jamie Karraker and Matt Gamache-Asselin.
“I have seen first-hand that lack of access to prescriptions and medical non-compliance can cause health to deteriorate, especially in elderly or immunocompromised people,” she said in a statement.
Boler-Davis was seen as a potential successor to Amazon’s former top consumer executive Dave Clark, who resigned June 3.
Boler-Davis was the only Black executive among Amazon’s senior leadership group. Amazon CEO Andy Jassy addressed her departure in an internal memo earlier this month.
