This is my personal site which reflects my professional career, skills and interests.
This site is also a throwback to the 80s and 90s when I grew up. This website does not contain any cookies or popups. Also, I'm not tracking any visitor data, which is why you won't find a privacy statement on my site.
I'm just glad you're here and therefore I'll grant you the bliss of browsing a site just as it should be.
I'm an entrepreneur and software developer. I wrote my first lines of code on an Atari ST when I was 8 years old. I founded my first company at the age of 19.
I also started the first Lean Startup Circle meetup group in continental Europe in an effort to create closer ties with other entrepreneurs facing the tough challenges of building a business.
Today I invest in software startups, build web applications and give talks and workshops about my experience and how to quickly validate your business idea.
From Signal To Evidence
Aside from building my own businesses I have spent a decade as a mentor for other startup founders as part of various European incubation and acceleration programs, such as Rockstart, Antler, YES!Delft and Utrecht Inc.
I wrote an ebook for aspiring entrepreneurs who are at the brink of launching a business around an innovative idea and are about to sink their life savings, corporate careers and most importantly, their valuable time into it.
In this ebook, I’ve collated and curated many available tools, blog posts and other resources in this book, which contains my selection of what's available and my view on when certain books, canvases and tools which might come in handy.
Business Case Calculator
As I built and invested in several SaaS companies over the years I've noticed that calculating all the SaaS metrics to justify investment decisions can be challenging.
I've built an online calculator for this, which also explains how all the metrics work. This calculator helps you work through the details quickly and produces an overview of key metrics and projections within minutes.
The calculator makes a quick, yet accurate ROI calculation for justifying investment decisions in marketing, product development and financing of products, content or licenses.
I'm actively investing in Dutch SaaS companies. This is my portfolio of active investments:
Eco-movement is the data aggregator and data provider of charging stations for electric vehicles in Europe.
The Firmhouse platform enables you to offer your product subscriptions with the blink of an eye. Fully stand-alone or connected to your existing website or e-commerce store.
For transport and logistic companies, NEXTdriver by SD-Insights is the continuous online driving coach to empower drivers to achieve more.
