Edward G. Sim is the founder and Managing Partner of Boldstart Ventures, an inception-stage venture firm with $1.1 billion in assets under management that he established in 2010 after co-founding Dawntreader Ventures and earning an economics degree from Harvard. His investment thesis targets pre-seed and seed stages in developer tools, SaaS, cybersecurity, and data infrastructure across the US, Canada, Europe, and Israel. Boldstart typically acts as a lead investor with check sizes ranging from $250,000 to $5 million, often partnering with technical founders at company formation. Notable portfolio companies include Snyk, Kustomer, BigID, and Superhuman, all of which were day-one investments. Sim is a board member or observer for several of these firms and has previously scaled enterprise startups to exit, including Greenplum and GoToMeeting. He is frequently described as the industry’s top seed investor and a “day one partner” who backs engineering-driven founders building the “Autonomous Enterprise”.
