Massive is a founder-led venture firm headed by two veteran operators who have built and exited five companies and invested in more than 120 companies. Massive invests in Seed+ through Series B at key inflection points, targeting industry-leading companies in inevitable and foundational deep tech sectors: The New Space Economy Vertical AI and Hyperscale Data Cybersecurity and Connected Systems Evolved Energy and Power Solutions These sectors represent emergent growth markets with exponential value creation potential by satisfying the future demands of humanity’s needs for essential resources. Ari and David have been founding, building, and investing in startups for a combined 50 years. We started Massive because our experience investing in, advising, and coaching hundreds of early-stage companies led us to the belief that the best time to invest in a high-growth business is when it reaches a breakout event - or inflection point - which positions the company for substantial, accelerated growth and minimizes downside risk. These inflection points can happen at various business stages based on industry or theme.
