Martech acquisitions in 2026: who is buying what (one in seven tools changed hands)

Sixty-eight of the 464 martech tools in the Martech Stack Builder catalog changed hands between 2023 and October 2026: about one in seven. Deals tripled from 2023 to 2025. Who bought them: software companies (44), private equity (13), data and information firms (5) and agency holding groups (4), which bought identity and data: Acxiom (with Interpublic), Lotame, InfoSum, and LiveRamp (agreed, pending). Salesforce agreed to buy Informatica, Contentful and Fin (formerly Intercom). Thirty-four tools were renamed, five to an AI or agent name. Why it matters: a new owner can change the price, the plan and the contract at your next renewal. Every deal, with its source, is in the Martech Market Report. #MartechExplained Chapters 0:00 One in seven changed hands 0:12 Deals by year 0:32 Who is buying 0:49 Agencies and data firms 1:12 Salesforce 1:43 Names move too 1:57 Why it matters at renewal Watch next The whole series: https://www.youtube.com/playlist?list=PLYUlLuffCem0 Watch with the transcript: https://www.martechstackbuilder.com/learn/martech-acquisitions-2026/ Build your own stack, free: https://app.martechstackbuilder.com #Martech #CDP
