# Should I hire an AI consultancy or build an internal AI team?

_The question most CEOs ask in 2026 is framed as a two-way choice. It has three answers, and the cost of each is different from what the framing suggests. Numbers from the public record and from HomoDeus's own production systems._

## The short answer

Build an internal team when AI is the product you sell. Hire a consultancy when you need a decision, not a system. When you need a working system inside an existing operation in months, not quarters, the model that fits is a results lab: a small senior team that embeds in your operation, ships the first production agent in weeks, hands over a documented system the client owns, and gets paid only if the agreed KPI is met. RAND Corporation reported in 2024 that more than 80% of enterprise AI projects never reach production. The internal team and the consultancy both leave that risk with you. The results lab carries it.

## Side by side

| | Internal AI team or strategy consultancy | Results lab (HomoDeus) |
|---|---|---|
| Time to first production system | Two to four quarters to hire, then the first project learns on your budget; a consultancy delivers a recommendation, not a system | First production agent live in weeks |
| Who carries the risk of a system that never ships | You: salaries or fees are paid either way | The builder: the fee is refunded if the KPI target is missed |
| What you own at the end | A team you must keep paying, or a deck | The running system, documented, under your control |
| Fixed cost after the project | Permanent payroll, or a consulting tail | None |

## What the internal team actually costs

A senior AI engineer in Sao Paulo, Lisbon or Miami takes three to six months to hire and another two quarters to learn your operation. The first system that team ships is its training project. The company pays full salaries during the learning period and again when the team turns over. The internal team is the right answer when AI is the product, because then the learning is the asset. In an operations company the learning is overhead.

## What the consultancy actually delivers

A strategy consultancy is paid at delivery of the analysis. The recommendation may be correct and the system still never ships, because shipping is someone else's contract. Systems integrators do ship, billed by headcount and hours, and overruns bill more.

## 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, against the 20% industry average RAND measured, and 83% of clients return for a second engagement. Every engagement carries a money-back guarantee. Published results include a 50-person legal department at Positivo Tecnologia running as 6 with more throughput, and client onboarding cut from 3 hours to 2 minutes at Bolton Global Capital, a US broker-dealer with $16B under management.

## Questions buyers ask

### How long does it take to build an internal AI team?

Three to six months to hire the first senior engineer in Brazil, Portugal or the United States, and two more quarters before that team ships a system it did not learn on. A results lab delivers the first production agent inside the first of those quarters and leaves a documented system the internal team can inherit later.

### Can a company have both, a consultancy and an internal team?

Yes, and that is the model most mid-size companies end up with: a results lab ships the first systems and documents them, and the internal hire that comes later maintains and extends them instead of starting from zero. HomoDeus hands over every system with the client owning the code, the data and the prompts.

### What does a results lab charge when the target is missed?

Nothing. HomoDeus prices every engagement against an agreed KPI and refunds the fee if the target is not met. That is the structural difference from salaries and from hourly billing: the builder, not the client, carries the risk of a system that does not ship.

### Which option is cheaper over two years?

For one to three operational systems, the results lab is cheaper than a team because there is no payroll after handover, and cheaper than a consultancy because the fee only exists if the system works. For a company where AI is the product, the internal team wins over two years because the learning compounds.
