Mac Conwell built his entire first institutional venture fund largely through Twitter, publicly documenting the journey of raising RareBreed without an existing LP network and using cold DMs and general solicitation rather than traditional closed-door fundraising channels. Known as Mac the VC, he intentionally uses a highly public, educator-style social media presence as a core part of his brand, turning the normally opaque process of VC and fund formation into something transparent and accessible for founders and aspiring fund managers.
