Brian Tighe
Principal Product Designer
Growth and Experimentation Lead @ Yahoo Mail
I design growth systems — the experiments, flows, and conversion mechanics that turn products into businesses. Over the last decade I've done that inside agencies, venture studios, DTC brands, and now Yahoo Mail, where I lead design for growth and experimentation across a product with hundreds of millions of users.
At HelloFresh, my experimentation work drove $75M+ in incremental value. At Yahoo, I lead AI adoption across the org — I co-founded a 120-person AI prototyping community that's changing how the company builds, and I use those same methods daily to move from idea to working product faster.
