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.
