“I joined Liminary because Sarah and I share the belief that next-generation AI must be technically rigorous and provide accurate, verifiable insights while maintaining a human perspective,” said O’Donnell.
“Throughout my career, I have focused on building systems that can scale globally without losing accuracy or reliability. Liminary stands out for its intentional product design and team. It is built to produce output that is reliable and usable for real-world decision-making, addressing gaps in an increasingly crowded but less personalized landscape.”
Andrabi founded Liminary after more than a decade working at the forefront of machine learning, search, and large-scale systems. She started as a security engineer at Microsoft and then joined Dropbox, where she developed machine learning (ML) models for ransomware detection and storage system anomaly detection. She went on to build the Growth ML team from the ground up and then lead Retrieval, owning search ML, infrastructure, and products across hundreds of millions of users. As head of intelligence, she ran Dropbox’s ML engineering organization, encompassing semantic search and ranking, recommender systems for search and collaboration, transcription, video editing, and Dropbox AI, the company’s first generative AI integration.
“I founded Liminary because I recognized a growing gap in how knowledge work is done. As complexity increases, organizations are plagued by disconnected workflows, inconsistent deliverables, and disjointed systems that slow decision-making and undermine confidence,” said Andrabi. “Until Liminary, there was nothing that effectively connected user content and context across tools. AI tools promise speed, but they often compromise the human perspective that brings value to accuracy, context, and insight.Liminary We solve these challenges by prioritizing accuracy, data-backed deliverables, and speed while maintaining the user’s perspective. We’re building systems that are reliable, traceable, and designed to give experts the confidence to make high-stakes decisions quickly and accurately.”
Mr. O’Donnell joins Liminary’s team of experts. That team includes:
- Ivan Traus, Founding Principal Engineer: He spent more than a decade at Dropbox, where he worked on the company’s core storage platform and was the technical director of the Nautilus search engine, which indexed over 1 trillion documents and served hundreds of millions of users around the world.
- Thomas Berg, Founding Engineer: Former ML and computer vision researcher at Dropbox. He spent over 10 years at Dropbox, where he received over 1,400 academic citations and multiple patents in semantic search and content understanding.
- Mitchell Hart, Founding Product Designer: Award-winning designer and former lead UX designer at Google (via Huge Agency). Previous work has spanned Google Pay, Android Pay, and Cameo.
- Alec Johnson, Software Engineer: Formerly an engineer at Hulu, Dropbox, and Braze, he is now a full-stack engineer at Liminary, focused on delivering the core end-user experience.
