About Investor

Nir Polak is a Board Partner at SignalFire and the co-founder and former CEO of Exabeam, bringing deep operating expertise in cybersecurity and enterprise security. Their firm focuses on seed and early-stage AI, enterprise software, cybersecurity, consumer technology, SaaS, and data-driven venture investing. The Board Partner role indicates the level at which they may participate in sourcing, diligence, investment decisions, portfolio support, or firm strategy. Founders should consider this investor when the company's sector, stage, geography, and technical or commercial needs align with the investor's direct experience and the firm's investment thesis. Their background can be especially valuable around product-market fit, go-to-market strategy, fundraising, hiring, strategic partnerships, and the milestones required for later financing rounds. They may also provide access to domain experts, experienced operators, prospective customers, co-investors, and follow-on capital through the firm's network. For founders comparing investors, the strongest fit is where the investor's sector knowledge, decision-making authority, and operating or investing experience match the specific challenges the company expects to face after the round.
