Sell-Side M&A Advisory for AI Companies

AI M&A AdvisoryFounder-led AI & software companiesApplied AI, data & MLOps, infrastructure, and model teamsUS & CanadaSenior MD-led

In brief

Windsor Drake runs confidential, competitive sale processes for founder-led AI and AI-native software companies in the US and Canada, led by a senior MD. Pricing splits by layer of the stack: foundation models and generative AI at 12x to 20x+ revenue, AI infrastructure at 6x to 10x, data and MLOps platforms at 6x to 9x, and applied and vertical AI applications at 3x to 6x. Proprietary data, unit economics after inference cost and retention move the number.

Who We Advise

Founder-led AI and software companies, across the stack.

We work with founder-led companies across the AI stack. Our clients are operators with real customers and real revenue who want senior, conflict-free advice on whether, when, and how to sell. Every engagement is led personally by the firm’s principal, not handed to a junior team.

Applied & vertical AI software

Operators with real customers and revenue using AI to win a specific industry or workflow.

Data & MLOps platforms

The tooling and data infrastructure that trains, deploys, observes, and governs models in production.

AI infrastructure

Compute, inference, orchestration, and the infrastructure-adjacent software AI workloads depend on.

Model & research teams

Foundation-model and applied-research teams whose data, weights, and talent a buyer cannot easily assemble.

What AI Companies Are Worth

Valuation by layer.

AI pricing splits sharply by layer. The premium goes to proprietary data, proven unit economics, and retention you can evidence, not to the word “AI” in a deck.

AI valuation by layer of the stack (EV / revenue)
Foundation models & generative AI12x to 20x+Proprietary data, durable inference advantage, earliest-stage scarcity
AI infrastructure & infra-adjacent software6x to 10xCompute economics, ecosystem position
Data & MLOps platforms6x to 9xWorkflow lock-in, data gravity
Applied, enterprise & vertical AI applications3x to 6xRetention, unit economics after inference cost

Indicative ranges; the earliest-stage model assets clear materially higher. For a fuller picture, see our breakdown of who buys AI companies and the current ranges in our AI software valuation report.

How We Run the Process

A senior-led, competitive process.

The work is hands-on from first call to close, and the founder is never handed off to a junior team.

01

Positioning and packaging

We frame your data, model, and revenue story for the specific buyers who pay for it, and prepare materials that survive diligence.

02

Buyer mapping

We identify the short list of strategics and sponsors whose roadmap or thesis fits your layer of the stack.

03

Competitive process

We approach buyers under NDA and run them in parallel, so price reflects competition rather than a single bid.

04

Structure and close

We negotiate cash at close, rollover, retention, and earnout terms, then manage diligence through signing.

Who Buys AI Companies

The three buyer pools for AI companies.

The right buyer depends on your layer of the stack. A process that reaches all three pools, and creates tension between them, is what separates a premium from a clearing price.

Strategic acquirers

Hyperscalers, enterprise-software and security platforms, and data and chip incumbents acquiring capability they cannot build fast enough internally. They price the time and cost of building the same thing, and most offers include retention packages for the technical team.

Private equity platforms

Sponsors buying applied-AI and vertical software with real revenue, retention, and a path to margin expansion. They underwrite cash flow, so gross margin after inference cost and net revenue retention carry most of the price, and offers often include rollover equity.

Growth & crossover sponsors

Investors backing model and infrastructure leaders, often the bridge between a private process and a larger strategic outcome. They pay for growth and market position, and many prefer a majority or minority recapitalization to a full sale.

What Buyers Underwrite

What a buyer examines first.

Buyers price an AI company on what diligence can verify. Six questions come first, and each one moves the price or the structure of the offer.

Data and model advantage

Whether the edge is proprietary and durable, or replicable with capital. Buyers test it by asking what a well-funded competitor would need to rebuild the product, and how long that would take.

Data rights and provenance

Where the training and fine-tuning data came from, under what license, and whether customer contracts allow their data to improve the model. Gaps here become specific indemnities and escrows in the purchase agreement.

Dependence on third-party models

How much of the product runs on a model the company does not control, and what happens to cost and performance if that provider changes price or terms. Products that can switch models, or run their own, carry less risk.

Unit economics after inference

Gross margin after inference and hosting cost, cohort by cohort, and whether it improves as usage scales. Buyers rebuild the margin from usage data and do not accept a blended figure.

Retention and revenue quality

Whether customers stay once the pilot budget ends. Buyers separate contracted recurring revenue from usage spikes and paid pilots, and give less weight to revenue that has not yet renewed.

Team and IP

The engineers and researchers a buyer would struggle to hire, and clean ownership of the code, models and weights. Invention assignments and open-source license compliance are checked line by line.

Before Going to Market

Preparing an AI company for a sale.

The work that protects price starts about a year before the first buyer call. Most of it is documentation that diligence will ask for anyway.

01

Twelve months out

Confirm invention assignments from every employee and contractor, audit open-source licenses in the code base, and record the source and license of every dataset used in training.

02

Nine months out

Rebuild gross margin by customer cohort after inference and hosting cost, and show the trend. Renegotiate any model or compute contract a buyer would read as a concentration risk.

03

Six months out

Assemble the evidence that the model works, including benchmark results against the alternatives a customer could use and error rates in production, along with the security and privacy documentation enterprise buyers request.

04

At launch

A buyer list built by layer of the stack, with the strategic rationale for each buyer written down before outreach, so every conversation starts from why that buyer should pay more than the others.

Why Windsor Drake.

Most founders sell once. The outcome depends on the judgment of the person running the process, their command of how AI buyers actually price and underwrite, and their willingness to protect your interest when it costs them convenience. Windsor Drake takes a limited number of engagements so each receives senior attention, and we advise only in sectors we know well, so buyers know a business we bring has been vetted and positioned by people who understand the category.

FAQ

AI M&A advisory: common questions.

What is my AI company worth?

It depends on your layer of the stack. LLM and generative-AI assets clear 12 to 20x revenue, data and MLOps platforms 6 to 9x, infrastructure-adjacent software 6 to 10x, and enterprise AI applications 3 to 6x. Proprietary data, unit economics, and retention move your number most.

Who buys AI companies?

Strategic acquirers such as hyperscalers, enterprise-software and security platforms, and data and chip incumbents; private equity platforms buying applied-AI vertical software; and growth and crossover sponsors backing model and infrastructure leaders. See our guide on who buys AI companies for the full buyer list.

What makes AI M&A advisory different from general technology M&A advisory?

AI is the most mispriced category in technology M&A. The same revenue can be valued at mature-software multiples or at double-digit revenue multiples depending on layer, data advantage, and which buyer is at the table. General technology M&A advisory tends to anchor on software comps; AI requires an advisor who can evidence a data or model moat, defend unit economics after inference cost, and reach the strategic buyers paying for capability rather than cash flow.

Do you advise machine learning, data, and AI infrastructure companies, not just AI applications?

Yes. We work across the AI stack, applied and vertical AI software, data and MLOps platforms, machine learning and AI infrastructure, and model and research teams. Each layer has a distinct buyer pool and valuation logic, and the positioning is built to the layer.

When is the right time to sell an AI company?

When your unit economics and retention can be evidenced, your data or model advantage is clear, and strategic buyers are actively paying for capability in your category. Selling into live buyer appetite is the difference between a premium and a clearing price.

How long does selling an AI company take?

Most sell-side processes run several months from preparation to close. The preparation carries the value: positioning, buyer mapping, and clean diligence materials should be finished before launch, not improvised during the process.

Does a generative AI startup need a sell-side advisor?

If it wants competing bids, yes. Generative AI and model assets price at 12x to 20x+ revenue on this page's indicative ranges, but the same revenue can be valued at mature-software multiples depending on data advantage and which buyer is at the table. A sell-side advisor approaches buyers under NDA and runs them in parallel, so price reflects competition rather than a single bid, then negotiates cash at close, rollover, retention and earnout terms.

What do acquirers pay for an AI infrastructure company?

On this page's indicative ranges, AI infrastructure and infrastructure-adjacent software price at 6x to 10x revenue, with compute economics and ecosystem position driving the premium. Strategic buyers here include hyperscalers and data and chip incumbents acquiring capability they cannot build fast enough internally. Growth and crossover sponsors also back infrastructure leaders, often as the bridge between a private process and a larger strategic outcome.

How are vertical AI software companies valued, and who buys them?

Applied, enterprise and vertical AI applications price at 3x to 6x revenue on this page's indicative ranges, below data, infrastructure and model assets. Buyers underwrite retention and gross margin after inference cost first, including whether customers stay once the novelty passes. Private equity platforms buy applied-AI and vertical software with real revenue, retention and a path to margin expansion, and strategic acquirers buy capability they cannot build fast enough.

How are AI company acquisitions structured?

The headline price is one term among several. Windsor Drake negotiates cash at close, rollover, retention and earnout terms, then manages diligence through signing, with the aim of converting a flattering headline into the best achievable terms. Buyers also underwrite team and IP, the talent and technology they would struggle to assemble independently, so the structure has to account for the people a buyer is paying for.
