Primary Venture Partners

Primary Venture Partners is a specialized, scaled seed fund that backs founders building things the world hasn't seen yet—at the moment before the crowd believes. Founded in 2015 by Brad Svrluga and Ben Sun, the firm's core thesis centers on identifying exceptional, often technical founders early and pairing capital with extraordinary operational support through the largest Portfolio Impact team of any dedicated seed investor. Primary employs a low-volume, high-conviction model—each partner makes only 2–3 investments per year after screening ~100 opportunities—across sector-specialized strategies spanning financial services, healthcare, vertical AI, infrastructure and compute, cybersecurity, consumer, go-to-market technology, and industrial evolution. What unifies Primary is a belief that 'venture capital is our business model, not our business'—the firm is in the business of helping founders. With $1.65B in AUM across five fund vintages and a 60+ person team (investors outnumbered 2:1 by operators), Primary embeds fractional executives, talent recruiters, GTM specialists, and strategic finance advisors directly into portfolio companies. The firm has historically focused on NYC but, with Fund V ($625M, closed February 2026), is actively backing founders from San Francisco to Tel Aviv, aiming to invest in 40–50 companies over three years at average check sizes of $5–10M.
