He emphasizes the importance of a user-friendly interface in data products and highlights the challenges of handling messy data.

To stay updated on industry trends, Lee suggests following newsletters like What's Hot in Enterprise SaaS and Stratechery, and using AI tools such as ChatGPT to quickly learn about specific topics.
