I take new products from zero to launch, then grow them.

In nine years as a product manager, most of my work has been starting products that didn’t exist yet and carrying them through their first stage of growth. That includes Flipster’s perpetual futures platform, Coupang’s first branding ad product, and Rooftop Slushie, a consulting marketplace I founded inside Blind.
