Memorious: Building Infinite Memory with AI
Forgetting is a universally human experience—whether it’s conversations, names, or moments—we all forget. But what if forgetting were optional, and humans could have perfect, infinite memory? This might sound like science fiction, but that’s the bold vision behind Memorious, a company founded by Spandan Madan and Gabriel Kreiman at Harvard. Their mission is to reinvent human memory with AI, creating tools that let people recall experiences, conversations, and information instantly—without searching or prompting.
From Research to Reality
The science driving Memorious comes directly from Gabriel’s lab at Harvard. A Professor of Neuroscience and AI at Harvard Medical School, Gabriel has spent decades studying how the brain encodes and retrieves memory. His lab’s discoveries laid the foundation for the company’s technology. He teamed up with Spandan Madan, a Harvard Computer Science PhD with deep experience in machine learning from roles at Microsoft, Adobe, and IIT. Together, they saw the opportunity to combine neuroscience and AI to build what they call “Ambient Intelligence.”
Memorious creates a “Memorome” for each user—an organized record of all your memories drawn from conversations, documents, photos, and location data. This allows the system to resurface memories contextually and in real time, much like the human brain, but with perfect recall.
Shaped by Customers
With support from the IQSS Startup Foundry, Spandan and Gabriel immersed themselves in customer discovery. Guided by mentors and experienced operators, they worked through several elements of early-stage company building. Through their customer discovery work, interviewing over 50 potential users, from older adults coping with memory loss, to project managers juggling complex information, and AI developers interested in building agents with human-like memory. They heard both urgency and opportunity. Older adults described being “desperate” for help, while professionals saw clear value in tools that could preserve organizational knowledge.
These insights guided the development of their consumer iOS app, now available in beta, and also inspired an enterprise API for memory extraction and retrieval. They are working closely with design partners to identify new, memory-native workflows which cannot be tackled with existing AI models from OpenAI, Anthropic, or Gemini.
Getting Down to Business
As first-time founders, Spandan and Gabriel brought world-class research experience but little business training. The Startup Foundry gave them their introduction to commercialization—teaching them how to frame their story for investors, design products and experiences for real users, and navigate a go-to-market strategy. With mentorship from seasoned entrepreneurs and industry experts, they learned to do everything from refining pitches to building scalable business models.
Building Momentum
Backed by this foundation, Memorious quickly gained investor confidence. The team closed a $3M pre-seed round led by Mayfield Fund, alongside other top Silicon Valley investors. With this support, they are scaling their engineering team, advancing their enterprise partnerships, and moving closer to their vision of augmenting human cognition by endowing humans with infinite memory.
Gabriel shares: "The IQSS Startup Foundry has played a transformative role in our journey from day zero. From educating me in the basics of how to go from research results to building a business strategy and plan, to making connections, to helping through multiple rounds of revising our pitch, I found a family of knowledgeable experts with in-depth expertise. Their enthusiasm, camaraderie, and rigor helped us navigate the key challenges and provided inspiration throughout the way."
Looking Ahead
The story of Memorious shows what happens when groundbreaking research meets entrepreneurial guidance. With strong Harvard roots, innovative technology, and early market validation, Memorious is on a path to transform how people and organizations remember.
