Investment thesis
Pebblebed is built on the premise that technical founders want technical investors. The firm backs people tackling technically rigorous problems it calls 'self-protecting ideas' β challenges that are simple to describe but punishing to execute and valuable because most people hear the plan and give up. It positions itself as a home for builders, offering physical workspace such as a San Francisco warehouse where founders can work. The firm makes roughly 20 investments per fund and leads rounds.
