It's pronounced Ger-sten-zang.
I'm a co-founder of Umbrella, a membership service for people 65+.
Most recently I was a Principal at Sidewalk Labs, investing and building urban-focused companies. Before that, I ran the product, design and data teams at Imgur, and was a member of the investment team at a16z. I've held various engineering and product roles and graduated from Stanford.
I think about augmented cognition, cities, software and economic development, lemons, collective intelligence and communities, organizational structure, and well-crafted furniture.
I'd love to hear from you.
My email address is my first and last name at gmail.com.
