Jonathan Heiliger is a General Partner at Vertex Ventures US, a boutique fund he started in 2015 after previously leading Facebook’s infrastructure team as it scaled to over 900 million users and serving as COO of Opsware[1][3]. Vertex US primarily invests in seed and Series A companies, with about half of its capital directed toward new infrastructure software and the remainder split between business SaaS and productivity tools for non-IT buyers[1][10]. His typical check size centers around $1 million, and he often acts as an early backer rather than strictly defining lead or follow behavior in public records[3][11]. Notable portfolio companies include Quora, Dropbox, PerimeterX, and LaunchDarkly, with Heiliger serving on boards for several such as PerimeterX, CloudAcademy, and SpaceIQ[3][6]. He emphasizes evaluating whether a technical problem is valuable beyond just being hard, particularly for founders building next-generation infrastructure software[1]. While he has spoken publicly on podcasts about counseling founders and building investor relationships, no distinctive published articles or written frameworks are widely cited in available sources[1][5].
