Mac Conwell is the Founder and Managing Partner of RareBreed Ventures, a pre-seed venture fund based in Baltimore, Maryland, that he launched in September 2020 after serving as a seed-stage fund manager at TEDCO from 2016 to 2020. His investment thesis targets exceptional, often underrepresented founders operating outside major tech ecosystems at the pre-seed stage, aiming to invest earlier than traditional investors. Conwell typically writes initial conviction checks ranging from $50,000 to $250,000 and leads these early investments alongside firms like Insight Partners and Carta. While his portfolio includes numerous early-stage companies, specific named portfolio examples are not explicitly detailed in the available search results beyond general descriptions of his focus. He distinguishes himself through a dual background as a software engineer and a two-time founder who achieved one successful exit to a Fortune 100 company and one failure. Conwell is recognized for his public advocacy of investing in founders "far from the parade routes" and has been featured in interviews discussing the gap for overlooked entrepreneurs at the earliest stages.
