Terre Layton,
an engineer by training, had worked in Silicon Valley for nearly two decades, for small startups and large companies such as HP Inc. and Sun Microsystems Inc., before she joined Sephora in 2011. Recruited as a product manager to lead the retailer’s website redesign, Ms. Layton says she found being in the presence of so many women leaders empowering after years spent in male-dominated workplaces. When it came time to brainstorm ideas, or even articulate concerns about a project’s direction, bosses made a point of asking team members for their opinions, she says. “You knew you were being heard. You had a voice,” says Ms. Layton, who last worked for Sephora in 2015 and now advises early stage startups on product management and user experience.
