Created and produced Casting Call in partnership with Gimlet Creative. Casting Call was as a reality-style podcast competition aimed at discovering the next great podcast host. The show featured aspiring hosts pitching their ideas and competing in challenges, with the winner receiving their own podcast series. The project broke into the top podcast charts and became a standout example of branded content that both entertained and elevated the podcast community.

Built the affiliate marketing program from the ground up at a time when competitors were already heavily invested in the channel. Through strategic partner recruitment, optimized incentives, and brand-aligned storytelling, grew the program to become one of Squarespace’s top-performing subscription-driving channels—and frequently ranking #1 on affiliate marketing performance charts across the industry.

Brianna helped establish Squarespace as the definitive brand in podcast advertising. She managed an in-house team and over $20M in annual spend, leading one of the most ambitious and culturally resonant podcast strategies in the industry. From indie favorites to top-charting shows, Squarespace became synonymous with podcast sponsorship—even spoofed on SNL. Brianna introduced innovations in dynamic ad insertion, performance modeling, and creative testing, while building long-term partnerships with leading creators and networks. She also advised Spotify as they developed their early podcast advertising strategy. Under her leadership, podcasting became one of Squarespace’s most recognizable and effective brand channels.
