Frequently asked questions
Where does Lightbank's underlying capital come from?
Lightbank's capital derives primarily from the personal wealth of Eric Lefkofsky and Brad Keywell, generated by the 2011 IPO of Groupon — the daily-deals platform they co-founded — which reached a market valuation above $12 billion. The firm does not raise blind-pool funds from outside limited partners, giving it the structural flexibility of permanent, discretionary capital.
How does Lightbank source its deal flow?
Lightbank's deal flow leans heavily on the founders' deep Chicago and broader Midwest network, as well as relationships built through previous startups including Groupon, InnerWorkings, Echo Global Logistics, and MediaBank. Lefkofsky's position as CEO of Tempus also creates a gravitational pull in health-tech and AI, generating proprietary looks at companies operating at the intersection of data science and real-world industry.
What investment stages does Lightbank typically target?
Lightbank focuses on early-stage technology investing, primarily Seed and Series A rounds. Initial check sizes have historically ranged from $1 million to $5 million, with the firm reserving capital for follow-on participation through later-stage rounds. The firm has occasionally participated in growth-stage rounds for existing portfolio companies but does not operate a dedicated growth-equity vehicle.
How is Lightbank related to Eric Lefkofsky's other ventures like Tempus?
Lightbank and Tempus are separate entities with overlapping leadership: Eric Lefkofsky is the CEO of Tempus, the AI-enabled precision-medicine company he founded in 2015, and simultaneously serves as Lightbank's co-founder and managing partner. While Lightbank's thesis includes digital health, Tempus operates as an independent company that went public via Nasdaq in June 2024, and Lightbank's investment activity is not limited to Tempus's ecosystem.
