Notion Acquires AI Search Startup ZeroEntropy to Boost Enterprise AI Performance
As part of the deal, Ghita Houir Alami, ZeroEntropy's founder and CEO, will join Notion to lead its newly formed Model Research team.
Workspace software company Notion has acquired AI startup ZeroEntropy, bringing its entire team on board to accelerate the development of faster and more efficient AI models for enterprise users. Financial terms of the acquisition were not disclosed.
As part of the deal, Ghita Houir Alami, ZeroEntropy's founder and CEO, will join Notion to lead its newly formed Model Research team, while co-founder and CTO Nicholas Pipitone and the rest of the startup's employees will also become part of Notion.
"After over two years full of training models and teams, writing kernels and papers, and optimising for latency and fun, I am beyond excited to announce that Notion acquired ZeroEntropy.
"We first got to know the Notion team as one of our top customers. Notion AI’s unified search has been running on our reranker zerank-2 for the past 2 months, replacing models from larger, better-funded competitors, with an 85% latency decrease," Alami said in a blog post.
Notion said it had been using ZeroEntropy's AI reranking model to power its unified search, replacing competing offerings from larger AI vendors.
Founded less than two years ago, the Y Combinator-backed startup developed specialised AI infrastructure focused on retrieval, search, and task-specific models. The startup built custom inference kernels, model optimisation techniques, and released open-source models such as zembed-1 and zerank-2, alongside research including its zELO training method.
Notion said the acquisition aligns with its goal of making AI more accessible and affordable for businesses of all sizes. "Customers need AI products that aren't just powerful, but also fast, affordable, and built for the specific work people do," the company said in a blog post.
The startup said that its products will remain fully supported until September 4, 2026, after which they will be discontinued. New customer registrations have been disabled, and existing users have been advised to migrate to alternative services using migration guides and dedicated support channels.
