Simon Last is a co-founder of Notion, which was founded in 2013 with Ivan Zhao as CEO. A 2024 profile in Every said he prefers to keep a low profile.
He is the driving force behind Notion AI. At a company offsite, Zhao, Last and members of the product and engineering teams built an AI prototype in a hotel room. Notion began experimenting with GPT-4 in early 2022.
Notion AI launched in February 2023. In September 2025 Notion 3.0 added AI agents. Last has since spoken about the shift from doing work directly to managing AI agents.
Notion raised $275M at $10B in October 2021. In January 2026 an employee tender of about $270M valued it at $11B.
