Director of Product, B2B
Former CPO at Notion · Product lead at Stripe · Harvard MBA
Diana Osei has built products at the intersection of simplicity and enterprise complexity for fifteen years. As CPO at Notion she scaled the product from 1 million to 20 million users in under two years. Before that she led Stripe's invoicing and billing product suite through a period of 4× revenue growth. Her Harvard MBA gave her the financial rigour; her time at Stripe gave her engineering respect; and her tenure at Notion gave her an obsessive focus on the end user. She teaches product management as a craft of decision-making under uncertainty.
