What does a tech due diligence cost?
Updated: 2026-09
A tech due diligence costs different amounts depending on the scope of the target system, the access available and time pressure. It is sensibly measured not against its own cost but against the risk of the transaction it protects.
On a technical review the price question is unusually posed, because it normally sits against a much larger number: the value of the transaction being decided. A review uncovering a material defect has paid for itself many times over.
The effort itself follows a few factors, and the most important sits not with the reviewer but with the target company: how well documented is it, and how complete is the access?
What drives the cost
Scope of the system
A single product is reviewed faster than a grown landscape of several systems.
Availability of access and documentation
Full access to code, systems and documents shortens the review considerably. Missing access is itself a finding.
Depth of review
An architecture assessment is more compact than a deep analysis of code quality, security and operational readiness.
Time pressure
A review inside a tight transaction deadline requires more parallel capacity than one on a normal timeline.
Breadth of assessment
Is only the technology reviewed, or also the team, the processes and technical debt with a cost estimate?
How we price
- 01
Fixed price
Where the scope can be clearly bounded, we work to a binding fixed price. You know exactly what it costs before the project starts — no open-ended hourly billing, no surprises.
- 02
Time and materials against an estimate
Where the scope is not yet fully settled at the start, we work transparently against effort — with an estimate discussed in advance and regular cost control, so nothing runs away.
- 03
Engagement / retainer
For ongoing support — advisory, governance or continuous optimisation — we agree an engagement with a defined scope per month. Predictable cost, flexibly adjustable.
We deliberately publish no online prices: every case differs. After a short first conversation you receive a binding fixed price or clear frame.

Matching offers
Tech due diligence
A tech due diligence examines what sits under the hood before an investment or acquisition: architecture, code quality, scalability, security and technical debt. The result is an honest risk assessment that can prevent an expensive wrong decision — before it is taken.
IT strategy & roadmap
An IT strategy answers which technical investments advance your business goals most — and in what order. The result is a prioritised roadmap that turns a diffuse wish list into an executable plan with clear action areas and milestones.
CTO as a Service
CTO as a Service delivers technical leadership on demand: well-founded architecture and technology decisions, roadmap planning and team guidance — without the cost of a full-time position. Suited to companies that need technical substance but cannot yet carry, or do not yet want, a CTO of their own.
FAQ
Why is there no specific price on the website?
Because a serious price depends on the actual scope, and a number online would almost always be wrong — too high deters, too low leads to unpleasant surprises. After a short first conversation we give you a binding fixed price or a clear range.
How do I get to a binding fixed price?
Through a short, free first conversation in which we clarify scope, goals and constraints. On that basis you receive a specific, binding price — with no hidden costs.
Is a review worth it on smaller transactions?
That is a judgement against the risk. Even a compact review uncovers the serious defects; a reduced review is almost always better than none.
What if the target does not grant full access?
Then what is accessible is reviewed and the gap is stated in the report. Refused access is in itself information for the decision.
