Mem is an AI-native note-taking and knowledge management application that automatically organizes information and surfaces relevant context at the moment of need. Unlike traditional notes tools that depend on manual tagging, folders, or backlinks, Mem uses language models to connect notes by meaning, recall relevant past knowledge, and generate summaries and drafts from a user's accumulated body of work.
The product positions itself as a 'self-organizing workspace' for individual professionals, founders, researchers, and writers who capture large volumes of ideas, meeting notes, and reference material. Features include AI chat over personal notes, smart writing assistance, automatic tagging, and contextual reminders.
Mem was founded in 2019 by Kevin Moody and Dennis Xu, both Stanford computer science graduates. Moody previously worked as a product manager at Google, while Xu was a product manager at Yelp. The company is headquartered in the United States.
Mem's funding history spans two main rounds. In April 2021 it raised a $5.6 million seed round led by David Ulevitch at Andreessen Horowitz, with participation from a16z's Cultural Leadership Fund, Will Smith's dreamers.vc, Floodgate, Unusual Ventures, and Shrug Capital. In November 2022 it closed a $23 million Series A led by the OpenAI Startup Fund, bringing total funding to roughly $28.6 million.
Mem's differentiator is being among the earliest consumer productivity apps designed natively around large language models, rather than retrofitting AI features onto an existing notes structure. It competes with Notion AI, Reflect, and other AI-augmented productivity tools, but stakes out a position closer to a 'second brain' than a structured workspace.
