Most acquisition coverage focuses on the price. The interesting analysis focuses on the structural consequence: what changed about the market after the deal closed, who benefited that was not a direct party to the transaction, and who lost competitive ground that was not obvious at announcement.
Salesforce acquires Slack ($27.7B, 2021)
The Slack acquisition was not primarily about adding a chat product to the Salesforce portfolio. It was a bet that the collaboration layer — where teams spend the most time outside of their CRM — was becoming the central operating surface for sales and service organizations. Microsoft had built Teams as part of Office 365 and was growing it aggressively. Salesforce needed a collaboration layer to avoid having Teams become the default context for every customer-facing workflow. The price reflected not the current value of Slack's revenue but the strategic cost of ceding the collaboration surface to Microsoft.
Microsoft acquires LinkedIn ($26.2B, 2016)
The LinkedIn acquisition gave Microsoft something that the entire enterprise software industry had been trying to build for a decade: a real-time professional identity graph. Every LinkedIn connection, job change, company growth signal, and professional relationship is data that sales teams and HR organizations would pay to access. Microsoft integrated LinkedIn data into Dynamics CRM and Sales Navigator, creating an account intelligence capability that no competitor without the same professional network could replicate. The acquisition was a data infrastructure move disguised as a social media acquisition.
Salesforce acquires ExactTarget ($2.5B, 2013)
The ExactTarget acquisition built the email marketing foundation of Salesforce Marketing Cloud and marked Salesforce's serious entry into the marketing stack. More importantly, it established the pattern of Salesforce using acquisitions to build the platform that its enterprise customers needed to run their entire revenue operation — not just their CRM. Every subsequent Salesforce acquisition (Pardot, Mulesoft, Tableau) was a continuation of this platform-building strategy that started with ExactTarget.
Adobe acquires Figma (blocked, $20B, 2022-2023)
The Figma acquisition attempt is as instructive for failing as the successful ones are for closing. Adobe offered $20 billion for a company with approximately $400 million in ARR — a 50x revenue multiple — which signals the existential competitive threat Figma represented. Design was becoming a collaborative, browser-based workflow that Adobe's desktop-native model could not address. The regulatory block that prevented the acquisition left Figma independent at a scale that makes it one of the few software companies capable of building a full creative platform to compete with Adobe's entire portfolio. The blocked deal may be more consequential than the deal that closed.
HubSpot acquires The Hustle (2021)
The Hustle acquisition — at a reported $27 million — is the smallest deal on this list and the one with the most interesting strategic logic. HubSpot bought a media brand to own an audience of entrepreneurs and small business operators. The acquisition was a bet that media is a distribution channel for software, that the relationship an audience has with a publication can be converted into awareness and consideration for software, and that building that audience through acquisition is cheaper than buying it through paid channels. The Hustle and HubSpot's content operation have grown into one of the most sophisticated audience-to-product funnels in B2B software. The deal was worth studying at $27 million more than most of the deals above at orders of magnitude higher prices.
What the best acquirers understand that others don't
The companies that have used M&A to build durable competitive advantages share a feature in how they evaluate targets: they are buying structural position in a market, not financial metrics. The price they pay reflects the cost of building the position organically — which is often higher than the acquisition price — not a multiple of current revenue. The acquisitions that change market structure are the ones where the buyer understood the structural value before the market had priced it. That is a different analysis than what most acquirers run.
