Hi! I'm Brian, a Fractional Head of Research & AI Builder.

I turn customer insights into shipped products that customers love.

Brian Greene

Fractional Head of Research

After shipping products for 150M+ users at Etsy, Bumble, StreamYard, and Meetup, leading both Research and Design teams, and teaching 200+ PMs, designers, and researchers to do discovery, I noticed every company struggles with the same thing: connecting customer understanding to what actually ships.

So I built systems that bridge that gap.

Testimonials

Eleana

Staff Product Designer, StreamYard

As a manager, Brian is empathetic, supportive, and honest, always eager to teach and empower the team. His influence shaped our company's culture while helping us make better design decisions.

Brian supported and guided the team to be more vocal and confident, involving us and giving us the tools to influence the product strategy and roadmaps. Brian's leadership has left a lasting positive impact on our team, and his dedication to fostering a supportive and growth-oriented environment has helped us skyrocket our user research skills to be more rounded designers.

Any team would be fortunate to have him as a leader and mentor.

Jason

Director of Design, Etsy

I had the chance to work directly with Brian at a critical time in Etsy's journey as a public company in 2018. He had exciting and bold ideas on how to help kick start more customer-centered work in our product teams. We both wanted our teams to spend more time with customers, specifically sellers, more often.

He drafted up an idea of a weekly pilot to bring customers into the office. Through his leadership and work, we were able to approach more innovative ideas, learn faster, and pivot or fail bad ideas. His energy and passion pushing teams to innovate were contagious.

I'd love the chance to work with Brian again.
