Build Assurance Review.
An independent read on whether your outsourced build is actually on track. Two weeks, a fixed fee, and a verdict a board can act on.
The Build Assurance Review is a fixed-scope Set Piece for non-technical founders paying an outsourced team to build their first product. Two weeks, from £6,000, ending in a plain-language verdict on whether the build is on track, a red, amber, green read across scope, pace, quality and spend, the risks ranked, and what to do next.
The problem it solves.
You are building your first product through an outsourced team, and you are not technical. The demos look fine. The invoices keep coming. But you cannot honestly answer the question that matters: is this on track, and is the money being spent well? Without a senior product owner in the room, you are trusting the people you are paying to mark their own homework.
That is not an accusation against the team. A good build partner builds what the plan says, and is right to. The gap is on your side of the table: nobody sitting there whose job is to check that the plan is still the right plan. I built and exited an agency, Atomise, number one on the UK Clutch 100 in 2025, so I know exactly what a well-run build looks like from the inside, and exactly what a founder cannot see from the outside.
What you get.
- A clear verdict. Is the build on track, yes or no, in plain language a board can act on.
- A red, amber, green read across the four things that decide whether this succeeds: scope, pace, quality and spend.
- The risks, ranked. What could sink this, in order, with what each one is costing you.
- A spend assessment. Whether what you are paying matches what you are getting, and whether the team on the invoice is the team doing the work.
- What to do next. A short, prioritised set of moves. Not a forty-page document nobody reads.
How the two weeks run.
- Access and orientation. Codebase, backlog, roadmap, the team, recent demos. One kick-off call.
- The review. Independent assessment of scope, pace, quality, spend and risk against where you need to be, not against what was promised in month one.
- The verdict, delivered. A working session walking you, and your board if useful, through the findings and the next moves.
Who runs it.
Alex Feltwell. Led the £10m Fidelity wealth migration programme at Bravura across a million-plus accounts, founded Atomise, Toptal top 3%. Deep in regulated fintech and wealth. Engineering assurance backed by the Atomise team where a technical deep-dive is needed.
Right fit, and not.
- Non-technical founder, first software product.
- Build run by an outsourced or offshore team.
- No senior product owner in-house.
- Funded or revenue-generating, with real money paying for the build.
Not this: technical founders who want to run it themselves, and teams that already have a senior product leader. Both should keep the money.
Before you sign, and after you know.
If the contract is not yet signed, start with The Scope, which is free: it audits the statement of work for unclosed decisions and for deliverables that are outputs rather than evidence. The Review is for once the build is running and the question has become whether it is running well.
Afterwards, most founders take the verdict and act on it themselves. Some ask for the seat to stay filled: senior product ownership alongside the build, one or two days a week, from £2,000 a month, equity-friendly where cash is tight. The numbers are published. It is offered when the Review says it is needed, and not otherwise.
Questions about the Review.
What is a Build Assurance Review?
A fixed-scope, two-week independent review of an outsourced software build, for a non-technical founder who cannot judge it themselves. It ends in a plain-language verdict on whether the build is on track, a red, amber, green read across scope, pace, quality and spend, the risks ranked, and a short list of what to do next. From £6,000.
How is it different from a code audit?
A code audit tells you whether the code is good. The Review tells you whether the right thing is being built, at the right pace, for the money, and what to do about it. Code quality is one of the four reads, not the whole review, and the technical deep-dive is done by the Atomise engineering team where it is warranted.
Do you need access to the codebase?
Yes, read-only, along with the backlog, the roadmap, recent demos and time with the team. A single kick-off call sets it up. Everything is under NDA and nothing changes in your systems.
Will my development agency object?
The good ones will not. A build partner doing the job properly has nothing to fear from an independent read, and most welcome a senior product owner on the client side because it makes their work easier. Reluctance is itself a finding.
What if the build turns out to be fine?
Then you tell your board that with evidence rather than hope, you know exactly what you are paying for, and you have a baseline to check against in three months. A green verdict is a good outcome, not a wasted fee.
What happens after the two weeks?
Most founders take the verdict and the plan and act on it themselves. Some ask for the seat to stay filled: senior product ownership alongside the build, one or two days a week, from £2,000 a month. It is offered when the Review says it is needed, and not otherwise.
