Lightbank | Growth Equity Investor

Job Brief

Lightbank, a Chicago-based venture firm with a track record of backing category-defining companies, is seeking a highly analytical and entrepreneurial investment professional to join its Growth Equity team. You will play a central role in building Lightbank’s new Growth Fund, focused on Series A–C investments in ambitious software, AI, and technology-enabled businesses across the Midwest, coasts, and beyond.

This is a rare opportunity to join a small, dynamic team with the resources of an established franchise but the mindset of a startup. The role combines private-equity style diligence with venture creativity: technical and financial analysis, market sizing, founder and customer validation, and proactive deal sourcing.

We are looking for self-starters who thrive in unstructured environments, can own analyses end-to-end, and want to build long-term careers in growth equity. Lightbank’s philosophy is to promote Partners from within.

Who is Lightbank

We aim to be the preeminent venture capital franchise between the coasts. While based in Chicago, we invest nationally and globally wherever ambitious founders are building great companies. Our past winners span Chicago (Tempus, Sprout Social, Tastyworks), Silicon Valley (Udemy), and other hubs across North America (Boom, Expel, SnapTravel).

We respect the role of the founder. The most important part of our job is to identify, partner with, and support great entrepreneurs. Our General Partners have built companies that raised over $3 billion in venture capital and created tens of billions of dollars in equity value. That operator DNA gives us credibility with both founders and LPs, and it informs how we evaluate, win, and support investments.

With the launch of our Growth Fund, Lightbank is extending this approach into later-stage, scaling businesses. The fund is led by Anish Aggarwal, who joined Lightbank as a Partner after investing at Vista Equity Partners, Insight Partners, and most recently as part of the founding venture/growth team at Alkeon Capital, a $25B+ crossover public/private investor. At Alkeon, Anish invested in high-growth startups such as Databricks, Armis, Navan, Verkada, AlphaSense, Drata, Snyk, Hotmart, Groww, and Harness, with notable exits including Moveworks ($3B acquisition by ServiceNow), OwnBackup / Own ($2B acquisition by Salesforce), and Hinge Health (NYSE: HNGE). This role will work directly with Anish and the broader Lightbank partnership across sourcing, diligence, and portfolio engagement.
