Harvey, the legal AI company used by law firms and in-house legal teams, has acquired Aida, a startup that sells AI software to sales teams, Harvey said on October 29. It did not disclose the price. Aida's co-founders, Piyush Prahladka and Atish Das Sarma, and their team of search and machine learning engineers join Harvey's product and engineering organization.
Aida is Harvey's fifth acquisition of 2026, by its own count, and the third in 105 days. Harvey's announcement says nothing about Aida's sales product. It said the team will work on helping each law firm build "its own ontology", a structured map of the firm's knowledge that its AI agents and models can draw on.
What Aida does
Aida's own site sells what it calls a Digital Twin for every sales rep: software that records meetings, reads email and call transcripts, tracks the commitments a rep makes to a customer, flags deals that have gone quiet and drafts follow-ups. It works through a Chrome extension, a Slack app, a desktop meeting recorder and a mobile app.
Prahladka, Aida's co-founder and chief executive, wrote in a letter on the company's site that he worked on search at Google, ads on Maps and a transit business at Uber before he "co-founded Glean and built much of its core." Das Sarma is Aida's co-founder and chief technology officer; Harvey said he previously led engineering, data science and growth teams at Patreon, Apple and X. Aida names 8VC and CRV as its early backers.
Why a legal AI company buys a sales tool
Harvey's announcement is about the people and the underlying technology, not the sales product. It said the Aida team's "skillset in sophisticated search and machine learning" complements its work to help firms "own, organize, and optimize their internal context."
Legal teams have decades of valuable knowledge locked away in documents and systems that are difficult to search and connect. Unlocking that knowledge securely will fundamentally change how they work.Winston Weinberg, CEO of Harvey, in the company's announcement, October 29, 2026
The problem Aida was built for is similar. Its site describes a sales team that loses deal history when reps leave and context scattered across email, calls and chat. Prahladka said in Harvey's announcement that Aida was founded on the belief that AI "could understand the context of people's work, connect information across fragmented systems, and turn that knowledge into action."
Gabe Pereyra, Harvey's co-founder, described the fit in a post on X, writing that he met Prahladka "a couple years ago" when Aida was starting.

Harvey's buying run
None of the five companies Harvey has bought this year made software for lawyers. Each deal brought the company's founders or team into Harvey.
Date | Company | What it made |
|---|---|---|
Jan. 21 | Hexus | AI product demos |
Mar. 3 | Lume | Customer integrations |
Jul. 16 | Benchmark | Deal tools for investors |
Sep. 9 | Guardrails AI | AI agent security |
Oct. 29 | Aida | Sales software |

The pace picked up in the second half. Harvey announced two deals in the first six and a half months of the year, then three between July 16 and October 29. Artificial Lawyer reported in March that only Lume's two co-founders joined Harvey and that Lume would stop operating, and quoted Harvey calling it its "second acquisition this year focused on talent."
The buying is backed by fresh money. On September 9, the day it announced Guardrails AI, Harvey said it raised $550 million at a $15.5 billion valuation, in a round co-led by Diffusion and Lightspeed Venture Partners. Harvey said 80% of Am Law 100 law firms use its software, and in July it said it had added more than $100 million in net-new annual recurring revenue in the second quarter.
What it means for Aida's customers
Harvey's announcement does not say what happens to Aida's sales product or the contracts of the companies that use it. That is a contrast with the Benchmark deal in July, when Harvey said the two teams were working on a plan to support Benchmark's customers "with continuity of service as a top priority." Aida's site was still offering its product and a customer login at 6:10 a.m. ET on October 30.
Das Sarma wrote on X that Aida "is now part of @harvey" and that the team had set out to build agents "that make people's roles bigger, not smaller."
