Reducto has acquired the AI learning platform Opennote to expand its capabilities in document intelligence and unstructured data processing, the companies announced this week.
The acquisition brings Opennote’s team and technology into Reducto as the San Francisco-based startup accelerates efforts to build infrastructure tools that help artificial intelligence systems interpret and process complex documents. Financial terms of the deal were not disclosed.
“Documents contain enormous amounts of value, but extracting that information accurately into something people, systems, and agents can act on is one of the most difficult problems in software today,” Reducto said in a blog post announcing the acquisition.
Founded in 2023, Reducto has emerged as one of the fastest-growing startups in the AI document processing sector, developing tools that combine optical character recognition with vision-language models to convert unstructured files into AI-readable data. The company raised $75 million in a Series B funding round led by Andreessen Horowitz last year, bringing total funding to more than $100 million.
Opennote, launched earlier this year, focused on AI-powered learning tools for students, including personalized tutoring, note organization, and interactive study features. The startup said more than 50,000 students had used its platform.

Reducto said the acquisition would strengthen its work on “document agents,” AI systems designed to interpret, organize, and act on large volumes of unstructured information. The company argued that Opennote’s expertise in helping users navigate dense educational material aligned closely with Reducto’s broader enterprise ambitions.
The deal reflects intensifying competition across the rapidly expanding AI infrastructure sector, where startups are racing to build tools that make large language models more effective at handling real-world documents, workflows, and enterprise data.
Industry analysts say document intelligence has become one of the fastest-growing segments of enterprise AI as businesses seek to automate workflows tied to contracts, financial records, healthcare forms, compliance documents, and research materials.

The acquisition also highlights how smaller AI startups are increasingly consolidating to compete with larger technology companies investing heavily in enterprise automation and agentic AI systems.
Reducto said the Opennote team would join the company immediately as it continues developing products focused on extraction, contextual understanding, and AI workflow integration.
