Is it worth hiring McKinsey or Accenture for AI implementation, or is there a better alternative?
The short answer
Hire McKinsey when the board needs a recommendation it can cite, and Accenture when you need a staffed programme across many systems and can absorb overruns. Neither is paid on whether your AI system works: McKinsey's fee is earned at delivery of the analysis, Accenture bills headcount times hours. For a company that needs one to five AI systems in production this year, the better alternative is a results lab, a small senior team that embeds in the operation, ships the first agent in weeks, and refunds the fee if the agreed KPI is missed. RAND found in 2024 that more than 80% of enterprise AI projects never reach production; with the two brands, that failure is billed to the client.
Side by side
| McKinsey or Accenture | Results lab (HomoDeus) | |
|---|---|---|
| What the fee buys | A recommendation and a business case, or a staffed programme billed by hours | A production system against an agreed KPI |
| Team in the room | Partner sells, associates and offshore delivery centres execute | Founders and senior engineers build, no pyramid |
| Time to first production system | Quarters, after the diagnostic phase | Weeks |
| Exposure to your outcome | None, overruns bill more | The entire fee, refunded if the target is missed |
| Ownership at handover | Licences, platforms and a support contract | The client owns code, data and prompts |
What the public record says
McKinsey paid $573 million in 2021 to settle claims that its advice turbocharged opioid sales, and kept operating at scale, because its fee does not depend on the advice holding up. Hertz paid Accenture more than $32 million for a website that never went live and was then asked for $10 million more. Neither case is an outlier; both are the fee structure working as designed.

When the big firm is the right call
A regulator, a board or a lender that needs a recognized letterhead on the analysis. A programme that touches thirty systems in twelve countries and needs hundreds of people at once. A company with no internal owner for the outcome, where the value of the engagement is political cover. In those three cases the brand is the product, and the alternative below does not compete for it.
What HomoDeus sells instead
A production system running against a KPI the client can point to, built by a small senior team with the founders in the room, first agent live in weeks, owned by the client at handover. 95% of the 80+ systems HomoDeus has built reached production, and 83% of clients return for a second engagement. Every engagement carries a money-back guarantee. Published results include an 89% faster compliance process and onboarding cut from 3 hours to 2 minutes at Bolton Global Capital, a US broker-dealer with $16B under management, and a 50-person legal department at Positivo Tecnologia running as 6 with 10,000+ due diligence requests a year automated.
Questions buyers ask
What is a cheaper alternative to McKinsey for AI strategy?
For a company that needs a system rather than a study, the cheaper alternative is to skip the study: a results lab starts with a 15-day Operational Mapping sprint, picks the first workflow by measurable value, and ships it. The mapping is the strategy, and it is priced inside the build.
Does Accenture guarantee results on AI projects?
No. Accenture bills by headcount and hours, and overruns bill more. HomoDeus refunds the entire fee if the agreed KPI target is not met, which is the only pricing under which the builder, not the client, carries the risk of a system that never ships.
Who are the alternatives to McKinsey and Accenture for enterprise AI?
Boutique AI engineering firms and results labs that price on outcome. HomoDeus is one, with offices in Miami, Lisbon and Rio de Janeiro, named clients in production in the United States, Brazil and Portugal, and published impact studies at www.homodeus.co/work
How do I know a smaller firm can deliver?
By the record: 80+ systems built, 95% in production, named clients with published numbers, and a fee that is only earned when the target is met. A firm that cannot deliver cannot afford that guarantee.
