Lightbank

Lightbank is a Chicago, Illinois–based early-stage venture capital firm founded in 2010 by Eric Lefkofsky and Brad Keywell that invests in pre-seed through Series A technology companies with a focus on disruptive digital, software, marketplace, fintech, and related sectors. The firm was initially capitalized with founder-backed funding and has deployed capital across a substantial portfolio of startups, supporting companies such as Groupon-related ventures, Sprout Social, Fiverr, SpotHero, and Udemy. Lightbank typically provides both financial backing and operational guidance, partnering closely with founders to scale products and teams while investing broadly across the U.S. technology ecosystem. Its investment approach emphasizes early engagement, strategic support, and sourcing opportunities outside traditional coastal hubs, including in emerging Midwest markets. Over its history Lightbank has raised multiple funds and backed dozens of companies that have reached significant liquidity outcomes or growth milestones.
