Why transparent pricing
Most consultants won’t tell you what they charge until you’ve spent two hours in discovery calls.
That wastes your time and mine.
Here’s the principle: where the scope is predictable, the price is fixed. Where the scope varies (because every company is different), I give you a clear floor so you can self-qualify before we talk.
No hidden fees. No “it depends” without at least a starting point.
The three core services
Fractional CTO
Strategic technology leadership on a monthly retainer.
For CEOs without a CTO, or CTOs who need a strategic partner.
- Minimum 1.5 days/week
- 6-month minimum engagement
- Flexible — scales up or down as needed
Starting from €8,000/month
The exact retainer depends on days per week and scope. Most engagements run between €8,000 and €13,000/month.

Book a free call →Technical Diagnostic
The fastest way to know where you stand.
Two days. A clear written report. Actionable recommendations you can act on the next day.
Ideal before committing to a longer engagement — or as a standalone if you just need an honest external view of your architecture and technical risks.
€3,500 fixed price
Includes: stakeholder interviews, architecture review, risk assessment, prioritized roadmap, written report (10–15 pages), and a debrief presentation.
Travel costs billed separately for distances over 50km.
Start with a Technical Diagnostic
Book a call →Architecture Assessment
A defined project with a fixed price.
For CTOs and IT leads with a specific challenge — legacy modernization, microservices split, cloud migration, architecture for a new product.
- 2 to 6 weeks
- Fixed price on a defined scope
- Free scoping session (half day) before we commit to a price
Starting from €15,000
Deliverables: Architecture Decision Records (ADRs), execution plan, board/team presentation.

Technical Due Diligence
For investors, acquirers, or founders preparing a funding round.
One week. A structured report with risks, recommendations, and modernization cost estimates — written for non-technical readers.
€8,500 fixed price

Team Coaching
Architecture workshops for engineering teams (DDD, CQRS/Event Sourcing, microservices).
€2,500/day — workshop format, on-site recommended.
How pricing is structured
Fixed where the scope is clear. Starting price where it varies.
The Diagnostic and Due Diligence are fixed — same work, same price, every time.
The Fractional CTO and Architecture Assessment depend on your context, your team, and the scope of the problem. I give you a floor so you can self-qualify. Then we scope it together.
No hourly billing. No time-tracking anxiety. No invoice surprises.
A note on value
A Fractional CTO at €8,000–13,000/month costs a fraction of a full-time senior CTO (€120,000–180,000/year fully loaded).
The difference: you get the expertise when you need it, without the overhead when you don’t.
A Technical Diagnostic at €3,500 that surfaces a critical architectural risk before it becomes a €200,000 problem pays for itself immediately.
