• Deep interest in the intersection of heavy transportation and autonomous technology. This is evident in the enthusiasm regarding a ride in a Waabi driverless Class-8 truck on surface streets, as well as the praise for Volvo integrating LIDAR into production vehicles like the EX90.
• A strong preference for combining professional networking with outdoor activity, specifically cycling. Frequent organization of group bike rides, such as the Taco Tuesday Ride, is used to connect people across the deep-tech and climate sectors, often replacing traditional meetings with gravel bike rides or morning loops.
• Focus on tangible industrial decarbonization and agricultural innovation. Highlighted investments include Pivot Bio for reducing nitrogen emissions in farming and Crusoe Energy for mitigating methane via digital flare mitigation, signaling an interest in hardware-heavy solutions to climate problems.
• Support for the circular economy and recommerce within the retail sector. Tweets frequently discuss the environmental impact of the fashion industry and celebrate milestones such as Trove partnering with Canada Goose to launch a resale site, viewing this as a critical step in reducing the industry's carbon footprint.
• Dedication to tracking climate progress through data and defined metrics. This involves sharing reports like the Speed & Scale update on net zero goals and analyzing the impact of remote work on commuting emissions, suggesting an appreciation for founders who bring quantitative evidence to their environmental claims.
