Startups & Scale-ups

Your first platform deserves a seasoned CTO.

You need to ship fast. But the wrong architecture now means painful rewrites at the worst possible moment — when you’re scaling. I’ve taken 8 platforms from first line of code to production scale. I know which shortcuts are safe and which ones will cost you a year.

As your Fractional CTO, I bring 35 years of building experience to the decisions that define your company’s technical future — without the cost of a full-time executive hire. You get the strategic clarity, the architecture discipline, and the battle scars of someone who’s done this before.

THE JOURNEY

From first idea to production scale. I’ve walked this path eight times.

Every platform goes through the same phases. The question is whether you navigate them with experience or learn the hard way.

Phase 0
Concept & Validation

Before writing a single line of code — is the idea technically feasible? What’s the minimum architecture that proves it? Where are the technical risks that could kill the business model? I help founders separate the real constraints from the imagined ones.

PHASE 1
Proof of Concept

The goal isn’t a product — it’s proof that the hardest technical challenge can be solved. A PoC tests the riskiest assumption first, not the easiest feature. I design PoCs that answer the questions investors and partners actually need answered.

PHASE 2
Minimum Viable Product

The MVP is where most startups make their most expensive mistakes — over-engineering what doesn’t matter, under-engineering what does. I help you build just enough to get to real users, with an architecture that won’t need to be thrown away when you grow.

PHASE 3
Product-Market Fit

You’re iterating fast based on user feedback. The architecture needs to support rapid change without accumulating crippling technical debt. This is where development discipline, code review practices, and automated testing become critical — not after things break.

Phase 4
Scale-Out

Product-market fit is proven. Now the architecture needs to handle 10x, 100x, 1000x the load — while the team grows from 3 to 30. This is where early architecture decisions compound. I’ve guided multiple platforms through this transition, including scaling Buckaroo from startup to market leader.

WHAT YOU GET

CTO-level decisions.
Fractional commitment.

Typically 2–4 days per month. Enough to steer the ship, not so much that you’re paying for overhead.

Architecture & Stack

Technology stack selection, system architecture design, database strategy, API design, and infrastructure decisions. The foundation everything else builds on.

Team & Process

Hiring strategy, team structure, development workflows, code review practices, and engineering culture. Building a team that can run without you — and eventually without me.

Security & Compliance

Security architecture, data protection, compliance roadmaps, and certification preparation. From GDPR basics to PCI-DSS — getting it right before it becomes a crisis.

Investor Readiness

Technical due diligence preparation, architecture documentation, scalability narratives, and CTO-level participation in investor conversations. Making your tech story investment-grade.

Roadmap & Prioritization

Product-technology roadmap alignment, feature prioritization from a technical perspective, and resource allocation strategy. Saying no to the right things at the right time.

Vendor & Tool Selection

Cloud provider evaluation, third-party service selection, build vs. buy analysis, and contract review. Avoiding vendor lock-in and over-engineering from day one.

TRACK RECORD

Platforms I’ve taken from concept to scale.

Startup → Leader

Buckaroo Online Payments

Co-founded and scaled from 2 people to one of NL’s leading PSPs. Thousands of merchants, millions of consumers. 13 years from founding to market leadership.

6 months

CJP — Education Platform

Concept to live system managing culture subsidies for hundreds of thousands of students. Financial reconciliation fully automated from day one.

10x reduction

InCaSe — Social Marketplace

Platform-as-a-Service enabling merchants to slash customer acquisition costs. Full journey from concept through PoC, MVP, to product-market fit.

Toweya — Federated Search

Custom search engine with ML ranking and a purpose-built database engine. Reduced response time from 3+ seconds to sub-second.

IS THIS RIGHT FOR YOU?

Honest fit assessment.

Every platform goes through the same phases. The question is whether you navigate them with experience or learn the hard way.

This works well when you...

This isn't the right fit when you...

Time to get IT right.

Building something that needs to scale?

The first conversation is always free and always honest. If I’m not the right fit, I’ll tell you — and I’ll point you toward who is.
