Harvey acquires AI sales platform Aida

Harvey said the acquisition would accelerate work helping each firm build its own ontology, which it described as providing critical context.[1] It also said Aida’s search and machine-learning expertise would complement work across Harvey’s product surface.[4] Aida was founded on the belief that AI could understand work context, connect information across fragmented systems and turn knowledge into action.[1] Harvey says legal teams hold valuable knowledge in documents and systems that can be difficult to search and connect.[1] Harvey said securely unlocking that knowledge would fundamentally change how legal teams work.[1]

Aida is Harvey’s fifth acquisition of 2026.[4] Before the Aida deal, Harvey acquired Guardrails AI in September and Benchmark in July; its earlier acquisitions also included Lume AI and Hexus.[2] The financial terms of the Aida acquisition were not disclosed.[2] Harvey raised $550 million at a $15.5 billion valuation in September.[2] Rival Legora also completed five acquisitions in 2026.[2]
