What happened
Notion announced on July 24, 2026, in a blog post by Sarah Sachs, that it had acquired ZeroEntropy, a startup that Notion said developed high-efficiency training and inference for task-specific AI models in less than two years. Notion said ZeroEntropy used custom kernels, its own inference stack and model-specialization recipes. The post did not give a price or any other deal terms.
Notion said ZeroEntropy's entire team was joining the company. Founder and CEO Ghita Houir Alami would lead a newly formed Model Research team at Notion. The post also named her cofounder and CTO, Nicholas Pipitone. Notion said team members came from backgrounds in AI research, quantitative finance and physics, and that the team trained the zembed-1 and zerank-2 models and published research on the zELO method. Notion said it first knew the team as a customer. It said ZeroEntropy's reranker made Notion's unified search up to 30% faster and cut reranking latency by 85%, while answer quality held constant and inference cost fell, replacing offerings from larger and better-funded competitors. Notion said ZeroEntropy shared its goal of making sure no business is left behind in the AI era.
