The problem
The developer misunderstood the product. The scope was never defined. The architecture was not built for what the business actually needed.Six months and €40,000 later, you are starting over. Or stuck with something that half-works and cannot be extended.This is not a developer quality problem. It is a technical leadership problem. Without someone who owns the architecture, the team, and the delivery - you are building on sand. That is the problem we solve.

How it works
In practice
A military training safety product ran on a single Android phone. No cloud. No API. Just a local Bluetooth app.We rebuilt the entire architecture: cloud backend, custom time-series database on TimescaleDB, real-time monitoring, scalable API, and a web interface in two languages.
Common questions
We already have developers. Do we still need this?
Having developers is not the same as having technical ownership. If no one is directing the architecture, the product is at risk regardless of developer quality.
What if our idea is not fully defined?
That is exactly what the Technical Audit is for. We define scope, architecture, and priorities before any development money is spent.
Do you work remotely?
Yes, fully remote by default. We have delivered for clients in the Netherlands, Germany, UK, Belgium, the US, and the UAE. Onsite available when needed.
What are your engineers' rates?
Mid-senior EU-based engineers at €25–€50/hour. Western European agencies typically charge €100–€200/hour. Same quality, no overhead.
What is the first step?

The problem
The moment most software projects fail is before the build starts — when nobody asked the right questions.What exactly are we building, and what are we not building? What does the architecture need to handle in 12 months? Who owns the technical decisions once the build starts? What is missing from this developer's quote?These questions are rarely answered before money changes hands. Then, months later, the scope has tripled, the budget is gone, and the product does not work. A Technical Audit answers these questions before you start.
Is this for you?
SITUATION 01
You have a product vision and are ready to start. But you are not technical and not sure how to evaluate proposals, scope the build, or write a contract that protects you.
SITUATION 02
A developer or agency sent a proposal. The price or technical approach feels wrong. You want an honest second opinion before you sign anything.
SITUATION 03
A previous build failed. The product is broken or incomplete. Before you start again, you need to understand what went wrong and what you are inheriting.
What you get
Written audit report - delivered in 3 to 5 business days
A real document, not a template with your answers typed in. It covers:
Architecture and technology stack recommendation with rationale
Scope gaps and unclear requirements in your current plan
Red flags in any existing developer proposals or contracts
Decisions that must be made before the build starts
Risk assessment - what breaks if the wrong choice is made here
Priority order for what to build first and why
How it works
The numbers
A typical 6-week MVP build costs €30,000 to €50,000. Rebuilding the same product because the architecture was wrong from the start costs roughly the same again - plus the months of delay, the runway burned, and the team momentum lost.If it prevents a single wrong architectural decision, this audit pays for itself many times over.
Cost of the audit
One week. Written report. Follow-up call.
Typical cost of rebuilding
Plus 3 to 6 months of lost time and runway.

Technical Audit
Fixed price · Delivered in 7 business days
60-minute technical discovery session
Written audit report - architecture, scope, risks, red flags
Decision log: what must be decided before the build starts
Priority recommendations: what to build first and why
30-minute follow-up call to review the report together
One-page action summary you can share with your team
Not included: development work, full technical specification, legal or contractual advice.
Common questions
What if I do not have any technical documents yet?
That is very common and completely fine. We work from whatever you have - a voice note, a pitch deck, a napkin sketch, a business plan, or just your idea explained out loud. The audit is specifically designed for this stage.
Is this useful if I already have a developer or a proposal?
It is especially useful then. Reviewing an existing proposal is one of the most valuable parts of this audit. We tell you what is missing, what is overpriced, what the architecture will not support, and what you should get in writing before signing.
What if I decide not to build after the audit?
That can still be a good outcome. Knowing not to build right now, or not with the current approach - saves significantly more than €750. The audit pays for itself either way.
How quickly can we start?
Usually within 2 to 3 business days of booking. The full audit is complete within 7 business days from that first session.
What happens next if we want to keep working together?
The natural next step is either the Fractional CTO Sprint - 30 days of technical ownership - or an MVP Build via topdevsourcing.com. Neither is required. You take the report and use it however makes sense.
Do you offer this in person?
The audit is delivered remotely by default. If your situation calls for an in-person session - a complex product, multiple stakeholders, a board presentation - we can arrange it. Contact us to discuss.
We step in as your technical owner for 30 days. Architecture decisions, delivery roadmap, team structure, and every major decision documented. Not consulting. Not advice. We own the technical outcome.

typical start time
45 minutes. Free. No commitment. We tell you honestly if this is a fit.
The problem
Your developers make architecture decisions based on what they know — not what your business needs. Scope expands. Choices made in week one become impossible to undo in month four. The product launches late. The budget runs over.Hiring a full-time senior CTO in Western Europe costs €120,000 to €180,000 per year plus equity. It takes 3 to 4 months to find the right person. During that time, your product drifts without direction.The Fractional CTO Sprint gives you CTO-level ownership starting within one week, at a fraction of that cost.
What this actually means
Own the architecture decisions from day one
Define the team structure and how it operates
Take responsibility for scope and timeline
Give developers specific weekly direction
Flag risks before they cost money
Document every decision for handoff
Write reports with no follow-through
Join monthly calls and send meeting notes
Advise without accountability for the outcome
Tell you what you want to hear
Protect developers from hard feedback
Leave when the engagement ends, no handoff
How it works
What is included
Not monthly check-ins. Regular structured sessions with a documented output every time.
Available via Slack between calls. Technical questions answered the same day.
Stack with rationale, system design, data model. Something your future CTO can build on.
Prioritised, realistic, scoped milestones with clear acceptance criteria. Not a wishlist.
Who you need, at what seniority, how to evaluate them, and what to pay.
We review existing proposals and tell developers directly what needs to change.

Common questions
What is the difference vs. a consultant?
Consultants deliver reports. We take delivery responsibility. Architecture, team, roadmap, and outcome are our problem to solve, not yours to manage.
We already have developers. Still useful?
Often this is where the sprint has the most impact. The problem is usually not developer quality — it is missing direction from above.
Our product is broken or behind. Can you help?
Yes, and this is common. We start with an honest assessment of what exists and the fastest realistic path forward.
Can we continue after 30 days?
Yes. Monthly retainer at €3,500/month after the sprint.
Remote or in person?
Fully remote by default. Onsite available with advance notice.

Why most MVPs fail
Founders hire the first developer they find. Or go to an agency that quotes low and delivers late. Or go offshore and spend three months in miscommunication. Or hire a full team before scope is clear and watch the budget disappear.The result is always the same: money spent, time lost, a product that does not work the way the business needed it to.In every case, the core problem is the same. Nobody owned the delivery. The developer had no product context. The scope was never precise enough to hold anyone accountable.We solve this differently. Define first. Right team. Delivery responsibility throughout. Full handoff at the end.
What we build
Scope is defined together in the scoping session. We build what lets you test your main assumption, show investors, or start selling.

Common questions
What if my idea is not fully defined?
The Technical Audit is the right first step. It gets you to a defined scope before any development money is spent.
What is actually in a 6-week MVP?
The core features that let you test your main assumption — defined together in scoping. We are direct about what fits in six weeks and what does not.
Do we own the code?
Yes. All code, all infrastructure access, all documentation. From day one. No lock-in.
Can you start this week?
In most cases yes. Book the scoping call and we confirm immediately. We can start within 24 hours of the signed project brief.
What if scope changes during the build?
We flag changes early - not at the invoice stage. Any adjustment to budget or timeline is discussed and agreed before it happens.
Remote or can you join onsite?
Fully remote by default. Onsite available for kickoffs or workshops - contact us to discuss.
