Hi, I am Jos. I live in Bussum, Netherlands, and have lived and worked in Berlin, Germany for more than 8 years.

I am a business IT consultant / IT project manager / CTO. I have founded several companies in the Netherlands and in Germany.

I am an “IT-guy” with commercial and business skills. I understand and can level with developers. I am skilled in building and leading (agile) development or sales teams; marketing; SEO; SEA; PHP / JS development; Web Design and Web Applications. I speak Linux (debian/centOS), Javascript, PHP, JSON, (my)SQL, HTML, CSS, Angular, XML.

I can audit and overview business operations in a short time — both the technical and the business side — and discover where the challenges are. I then solve those issues using the available or new technology.

I have 20+ years of entrepreneurial / working experience in the Netherlands (12+yrs) and 8+ years in Germany. I speak and write Dutch, English and German fluently.

I like technology, design, entrepreneurship and web development. And coffee, laptops, cars, biking, Lego and weekends. I have three kids and an amazing wife.

Feel free to contact me.

CEO / Founder
Pinkcube GmbH, Berlin2012-2019

I founded Pinkcube GmbH mid-2012 in Berlin, after having co-founded Pinkcube BV in 2009. Pinkcube GmbH grew out to be one of the challenging players in the promotional products market. Started with no employees, a small office space of 15m2 and growing to a team of 8, an office on the Karl-Marx-Allee and € 1.5M revenue in 2018. We did this by setting up the best web site in the industry (based on Shopware), and very active innovative Adwords advertising. As founder and CEO I was responsible for hiring the team, Adwords campaigns, developing the vision for the web stores, payroll, administration and financing.

Pinkcube GmbH was sold to Promostore in 2019.

We started a company selling promotional products (B2B). We have rebuilt the ordering process from the ground up. At first using 25+ web shops for each product category, later rebuilt to an advanced custom made platform built on Magento. We thought that ordering promotional products should be easier, better and more transparent, and improved the whole process as one of the first in this market segment. 

Pinkcube is now one of the largest and well-known suppliers in the dutch market.

Co-owner / CTO
Flits Internet Professionals, Hengelo1999-2014

I started a web site development agency during my bachelor studies, which grew to around 15 people. We were developing web sites for small and medium sized businesses. At first (1999/2000) mostly HTML business-card-type sites, and later on sophisticated e-commerce and CMS platforms, mostly using open source frameworks such as Joomla, Typo3, Wordpress and Magento and using PHP, Javascript and MySQL.

As CTO I was responsible for the team and development. I also helped designing web sites using Photoshop, and helped improving usability and conversion. Also I worked as a web consultant helping our clients improving their revenues using internet.

At Viavisie, a division of Aegon, I was a financial planner and mortgage broker, visiting employees of larger companies at home. I made reviews of all clients' possessions, assets and debts and available pension funds, and summarized all of it in a comprehensive report. That way I was able to advise my clients on investment strategies.

Shoptower, Hengelo2001-2003

We started an early e-commerce startup to provide local "brick & mortar" office supply-shops with webshops complete with article database from national distributors like Ingram Micro, Intercambio, TechData, Landis, Datelcom, McDos, and Holland Pharma. Focus areas were office supplies, office furniture and office hardware (pc's, printers etc.). We used drop-shipments as one of the first in the market. We built the whole e-commerce system from ground up, using PHP, Javascript and MySQL. This included database connections with around ten distributors; creating a product base of more than 100.000 products, of which our customers could choose product lines to resell. We were too early developing this kind of business channel, and ran into many challenges we were unable to all overcome. We ended this company and re-focussed on our internet agency.
