Forum Ventures

Forum Ventures is a venture capital fund and accelerator that has been operating since 2014, backing early-stage B2B tech startups with pre-seed and seed funding. The firm has made over 500 investments across its portfolio, which collectively has raised more than $1 billion in follow-on funding. It operates out of New York, San Francisco, and Toronto, with a founder community numbering over 1,300. For cybersecurity professionals, the relevance is indirect but real. Forum Ventures invests in B2B tech and AI-native B2B SaaS - verticals where security tooling, compliance infrastructure, and threat detection are frequently core product features or critical integration layers. Portfolio companies building in these spaces need teams that understand adversarial thinking, secure-by-default architectures, and the operational realities of shipping software that enterprises will actually trust. The firm runs accelerator programs and a venture studio that embeds directly with founding teams, offering go-to-market support, fundraising guidance, and customer introductions. That hands-on model means security-conscious hires at portfolio startups aren't just plugging holes - they're often defining the threat model from scratch, choosing the stack, and building the posture that determines whether the product makes it past enterprise procurement.
