Every industry — from finance to wellness — relies on in-person convening to strengthen the industry, share knowledge, and create deal flow. Yet until now, no one has treated these live experiences as investable assets. That’s where Events Venture Group (EVG) comes in. We’re a venture capital network of world-class event founders and operators — a braintrust that vets, funds, and actively advises the next generation of event entrepreneurs. For investors EVG is an educational and networking club fueling the success of groundbreaking entrepreneurs with access to strategic funding, expert mentorship, and our collaborative community of event seasoned members. For founders, we back early-stage event founders — usually 0 to 3 years in, who have the vision but need structure, and strategic support to grow sustainably. We’re the industry’s only hybrid (VC+PE) capital network dedicated to helping founders get ‘capital ready’ and exit strong. Reach us at info@eventsventuregroup.com
