Rachel Geller is a Managing Director at Insight Partners who built her career starting on the Insight Onsite side, where she scaled and led the internal strategy and M&A team, evaluating hundreds of potential investments and supporting M&A and growth at 50+ portfolio companies, giving her an unusually deep operator-style and transaction-focused background for a growth-stage investor. She brings prior experience in strategy consulting and product marketing at American Express to help founders think rigorously about customer value propositions, product positioning, and scaling go-to-market engines, rather than viewing investing as purely financial engineering.
