How do we get a senior team to design, build and hand over our AI platform without hiring one?
Fractional AI implementation team
Sold asFractional AI Implementation Team · Retained · typically 2–3 days a week · one statement of work
A permanent AI platform team takes two quarters to hire and land, and a programme without one makes its technical decisions by accident in the meantime. A fractional implementation team puts that capability in place now. We own the target architecture and the vendor and model decisions, we build the platform and the first production workflows alongside your engineers, and we enable your team to run all of it. It is retained rather than fixed-scope, typically two to three days a week under one statement of work, and every decision is written down and dated so the reasoning outlives the engagement.
The problem this solves
A programme with a budget, a mandate and nobody who owns the architecture or the build. The decisions still get made. They get made by whoever is in the room: the loudest vendor, the team with the nearest deadline, or the last proof of concept that happened to work. The build waits for people who have not been hired.
Permanent hires fix it eventually. Two quarters of search, notice and ramp is the usual cost, and most of the decisions that shape the platform are taken before the team arrives.
If you are still working out what the missing role is, our guide to what an AI solution architect does sets out the decisions it owns and how it differs from a machine learning engineer or a data scientist.
How the engagement runs
A standing cadence, so the ownership is real rather than an advisory line on a slide.
Architecture ownership
We hold the target architecture and the trade-offs behind it, and we are answerable for them the way an employed lead would be.
Hands-on implementation
We build it. The platform, the integrations and the first production workflows are written by the people who drew the architecture, in your repositories and alongside your engineers.
A weekly decision log
Each decision, the options weighed and the reason for the one taken, written down and dated. It is the artefact that outlasts the retainer.
Review of work in flight
Technical review of what your teams and your suppliers are already building, so a problem is caught while it is still a design question. For a supplier that cannot hand over an audit report, the security review guide listed at the end of this page sets out what to ask for instead.
Vendor and model decisions
Which model, which platform, and where the build-versus-buy line falls, with the production evidence behind each choice stated rather than asserted.
Enablement
The point of the engagement is that it ends. Your engineers build with us from the first sprint, then take the platform, the log and the operating model and run them without us.
What you are left with
A working platform, an architecture and a decision record your own team can defend to a board, to an auditor or to the next supplier, and engineers who built all three with us.
A written handover, so the end of the retainer is a date in the contract rather than a cliff.
Whoever does the work, the first month should already show early evidence of that end state. Our guide to what the first 30 days of an AI implementation should deliver, listed at the end of this page, sets out what to see each week.
Staff augmentation or a managed AI team
Two ways to add a team to an AI programme get confused. Staff augmentation adds engineers who work under your direction, in your backlog, for a term. A managed AI team takes responsibility for an outcome: it holds the architecture and the technical decisions, decides how its own people spend their time, and answers for the result. Both are sound ways to buy. Which one fits depends on whether someone on your side already owns the architecture and the delivery.
| Dimension | Staff augmentation | A managed AI team |
|---|---|---|
| Who directs the work | Your technical leads, day to day | The team, against outcomes and decisions agreed with you |
| Who owns the architecture | You do, and the engineers build to it | The team holds it and the decision record; you make the final calls, and both are handed over |
| What you pay for | Engineers' time, for a term | A standing cadence of senior time against an outcome, under one statement of work |
| What you need in place | Technical leads and a backlog ready to work on | A funded programme and a mandate, even with no technical owner yet |
| Main risk | Capacity without direction: engineers build what is asked, including the wrong thing, if nobody senior reviews the design | Dependency: the knowledge stays with the team unless enablement and a written handover are in the contract |
| Fits when | Capacity is the constraint and the plan is sound | Ownership is the constraint and nobody holds the technical decisions |
The two also combine. A managed team can set the architecture and review the design while augmented engineers add capacity under it, which covers both gaps at once. 1AYM offers both: this retained implementation team is the managed route, and Embedded Engineers on Contract is the staff augmentation route, with engineers inside your programme on a contract from three months. US clients can contract for either through 1AYM's US entity.
When it is the wrong choice
When the problem is already scoped, a fixed-scope engagement is cheaper and faster. A feasibility sprint settles what to build; an architecture and production build ships it. Both are priced against a defined output, which a retainer is not. If you already have a scoped job and need it resourced, 1AYM can staff it on contract from the collective of associates who work with the firm, held to the same standard as the rest of 1AYM.
How each shape moves the risk of an overrun, and the other lines an AI budget has to carry, is set out in our guide to AI implementation cost.
It is also the wrong shape when what is missing is full-time capacity inside your own team rather than a team that owns the outcome. That is a contract for embedded engineers, and it has its own page below.
Nor is it an executive seat. If what is missing is someone on the leadership team who answers for AI across the business, our guide to choosing between a chief AI officer and a head of AI sets out what each role owns and when to hire one.
If the question is still whether to hire at all, our comparison of hiring an AI engineer, contracting one and bringing in a team sets out how each route starts, who manages the work and who owns the code.
What you get
- Target architecture, owned and kept current
- The platform and the first production workflows, built alongside your engineers
- A dated decision log covering vendor, model and build-versus-buy choices
- Technical review of work already in flight
- Delivery governance: gates, review points and release criteria
- Enablement so your own engineers take the architecture over
- A written handover at the end of the retainer
Start here if
- A funded AI programme with no single owner of the architecture
- Vendor recommendations are the only technical opinion in the room
- A permanent platform lead has been open for a quarter or more
- Work is in flight and nobody senior is reviewing the design
- The architecture is agreed but there is nobody to build it
Frequently asked questions
How much of the week does the retained team hold?
Typically two to three days a week, under one statement of work. The shape matters more than the total: ownership that only appears at an escalation is advice rather than ownership, so the days are a standing cadence.
Who makes the final call on a model or a vendor?
You do. We hold the decision, set out the options and the reasoning, and put a date on it. What that buys is a record you can defend a year later, and an argument settled on evidence from production rather than on who presented last.
What stops this becoming a permanent dependency?
The enablement sits inside the engagement rather than after it, and the handover is written as we go. Your engineers build the platform and hold the architecture and the decision log alongside us, so the end of the retainer is a date rather than a risk to manage.
