AI Business Models.

In this model, an established software company sells AI to the customers it already has, as a paid add-on, a higher tier or a credit meter. The distribution is the advantage: there's no need to find new customers, because AI shows up inside a product they already use. Microsoft 365 Copilot shows both the scale and the challenge. It passed 30 million paid seats by July 2026², yet in January 2026 its 15 million seats were only about 3% of Microsoft 365's more than 450 million commercial seats^1,3. Customers try AI easily. Getting them to pay extra for it is much harder, so many vendors end up bundling AI and raising prices for everyone.

The installed base is the funnel

Unlike the other models, this one starts with customers who already pay. The map's acquisition row is about selling AI to them: prompts inside the product, a free taste of AI, account managers, launch events and renewal conversations. The main path runs from noticing AI to trying it, building a habit and finally getting someone to approve the spend. That last step matters because the buyer is usually an admin or a budget owner, not the person using the feature.

Pilots have to prove value before seats expand

Enterprise AI add-ons are often bought for a small group first. Expansion comes when that group proves the value, which is the seat expansion loop on the map. Proving it has been slow. In a 2025 survey of 187 IT leaders by the research firm Gartner, presented by Gartner analyst Dan Wilson, nearly half of the companies that had tried Microsoft 365 Copilot rated it "some value, shows promise." Only 5% of those that finished a pilot were moving to a larger deployment⁴.

Buyers expect AI to be included

Customers increasingly see AI as part of the product, not an extra. In interviews with 350 software buyers, G2, the software review site, found that 81% expect core AI in the base product and only 6% favor selling it as a separate add-on. Roughly one in four called a 20% AI premium a dealbreaker⁵. The consulting firm SBI reports that 58% of software vendors already include AI in their core packages at no extra charge, though it hasn't published how it measured that⁶.

Adoption is rising, but it won't fix the add-on

Use of AI at work is climbing. Microsoft 365 Copilot went from 15 million paid seats in January 2026 to more than 30 million by July^1,2. A Gallup survey of more than 22,000 US workers in late 2025 found that nearly half use AI at least a few times a year, about a quarter use it a few times a week, and 12% use it daily, up from 21% who used it at all in 2023. Gallup also saw signs that growth may be starting to level off¹¹. Even so, more usage doesn't mean more customers will pay for a separate add-on, since buyers expect AI to be included. Our view, an inference rather than a finding, is that the likely end state is AI bundled into every plan with a price increase, plus credits or a meter for heavy use.

So vendors bundle AI and raise prices

When few customers pay for an add-on, the common answer is to put AI in every plan and charge more for the plan. That's the bundling loop. Google dropped its separate Gemini add-on in January 2025 and put Gemini into every Workspace business plan, at a higher price. Before, a Business Standard customer paid $12 per user per month for Workspace, plus $20 for Gemini. After, the plan cost $14 with Gemini included. That was a big cut for the few who had bought Gemini, and a $2 increase for everyone who hadn't⁷. Notion retired its standalone $10 AI add-on in May 2025 and made Business, at $20 per seat, its AI tier⁸. Slack stopped selling its AI add-on that summer and moved AI features into its plans⁹. Canva raised some Teams prices by up to 300%, citing new AI features¹⁰. Salesforce raised prices 6% on its main Enterprise and Unlimited editions in August 2025, retired its standalone AI add-ons and moved customers to Agentforce bundles priced from $125 to $550 per user per month, with Flex Credits for usage¹². Microsoft went the other way, bundling Copilot into a new $99 E7 suite, where E5 at $60 plus Copilot at $30 would cost about $90 separately³.

AI costs drag on a high-margin business

In classic software, serving one more user costs the vendor almost nothing. AI features cost compute every time they're used, including when they're bundled in for free. SBI says companies that absorb those costs miss revenue targets at twice the rate of companies that charge for AI separately⁶. That's why the third option on the map is a meter. Notion added credits for its AI agents in August 2025⁸, and Microsoft CEO Satya Nadella has suggested pricing that combines subscriptions with usage limits and a meter³.
