Mark Suster is a venture capital investor at Upfront Ventures who built his reputation as an "operator-turned-investor" after founding two enterprise software companies, including one sold to Salesforce, giving his advice a grounded, practitioner tone that founders seek out for its real-world specificity. He became one of the earliest VCs to build a large personal brand through his "Both Sides of the Table" blog, which functions as a public VC handbook with detailed breakdowns of term sheets, board dynamics, and fundraising strategy that other VCs rarely document in such depth.

• A focus on the transition to autonomous AI agents. He is actively thinking about how software is shifting from human-driven to agent-driven models and the massive increase in infrastructure and compute power required to support that future.
• Strong advocacy for the Los Angeles tech ecosystem. He consistently champions LA as a premier hub for building hard technology, particularly in sectors like space, energy, and national defense, often noting the city's unique advantages over other regions.
• Deep interest in macroeconomics and demographics as destiny. He closely follows thinkers who analyze how topography and population trends predict global shifts, specifically citing Peter Zeihan's work as a way to understand what will happen a decade before it occurs.
• Respect for venture capital fundamentals and hardworking firms. He values investors who show up, do the actual work, and offer polite but firm convictions, explicitly praising peers at firms like Kleiner Perkins for bringing real insights rather than just money.
• Belief in the mobility of capital and talent. He frequently argues that economic incentives matter and that high taxes or poor policy can drive away investment, talent, and the future tax base, as high-net-worth individuals have the resources to relocate.
• Passion for the NFL, particularly the Philadelphia Eagles. He actively watches games and comments on the nuances of referee calls and league rules, such as taunting penalties, showing he is a genuine fan of the sport.
