About this episode
Max Mullen discusses the journey of building Instacart and insights on investing and consumer markets.
Max Mullen is the co-founder of Instacart and an active investor having invested in 100+ companies including Gumloop, Mercury, Owner among others. He also runs a founder community in San Francisco called Workshop. We discussed the full arc of building Instacart from a contrarian idea that investors rejected to a $10B consumer marketplace. Max highlighted the scrappy early days, marketplace product-market fit, and key inflection points like retailer partnerships and the Amazon–Whole Foods moment. We also explored what makes great consumer founders, why the best ideas look wrong at first, and how to build and scale in “hard mode” markets. Finally, the conversation touched on investing, decision-making frameworks, and what it takes to win in consumer over the long term. --- Timestamps: (0:00) Intro (0:36) The inception of Instacart (4:55) Finding product market fit (7:20) Landing Trader Joe’s (11:04) Big levers for growth (13:36) Operationally complex businesses (14:55) Amazon’s acquisition of Whole Foods (17:50) COVID and Instacart’s IPO (20:02) Prioritizing profitability (23:21) Avoiding temptations (24:59) The future of Instacart (25:53) Investing in consumer (28:21) Irrationally…
