Every business is built to be run in-house, on own technology, and a new category starts only once the previous one stands on its own. Everything runs from Apeldoorn.
Own platforms. Shops, search engines and servers, built and hosted in-house.
Multi-market. Selling and comparing across NL, DACH, UK and US, with content and pricing for each market.
Short lines. Decisions, development and operations sit close together.

Approach
Own companies. Every stage.
No investments in other people's startups. Own time, money and technology go into self-started companies, hands-on from the first idea to the next market.
01
Spot
A category where shoppers know what they want but struggle to find it. Snow chains in 2011, sneakers in 2013, contact lenses in 2026.
02
Build
Platform, catalogue, feeds and servers, built in-house by Ingteractive. No agencies, no dependency on third-party licences.
03
Launch
Brand, content and SEO from day one, and Emailzilla to turn first customers into returning ones.
04
Grow
Conversion work, pricing, automation and partnerships with retailers and affiliate networks.
05
Scale
The same engine into new languages, currencies and categories. One shared platform, one more market at a time.
Portfolio
Built, owned, operated.
Every brand below was started in-house and runs on in-house platforms. Webshops that sell, search engines that send buyers, a game studio and the services that grew out of all three.
A sneaker search engine, rebuilt from scratch in 2020. Live prices and stock from curated shops, 500+ brands, filtering by size and colourway, a proprietary Hypescore ranking and editorial buying guides, written per market. Live in the Netherlands, Germany, the UK, the US and the rest of Europe.
The same engine pointed at a new category: contact lenses. A recurring purchase with predictable demand, and proof that the model works well beyond footwear. Launched in 2026 and live in Dutch, German and French as Lenzenzilla, Linsenzilla and Lentizilla.
How Sneeuwkettingen4u changed the snow chain market in the Netherlands.
Snow chains used to be a product you bought in a hurry at a petrol station, with little advice and no idea whether they fit. Sneeuwkettingen4u made it a specialist online category: size-specific advice, a wide range of brands and fast delivery before the first snowfall. It grew into the largest shop in the group, with a German sister store for the DACH region.
VDIW Game Studios is the game development label of Van den Ing Webmarketing. Original titles, designed, built and published in-house, with AI used throughout production for art, voices and music.

Starcorp Tycoon
Early AccessWindowsEconomic strategy
2246. You did something ridiculously petty. Maybe you parked a freighter in a loading bay. Maybe you returned a library book 40 years late. The fine is absurd and you will never pay it. So THE CHAIR, a tiny, ancient ant judge on an enormous throne, offers you the alternative: Corporate Service. You may choose. (You may not.)
You get Licence N: StarCorp, an empty government shell company, dropped into a closed market of 26 star systems ruled by up to seven established corporations. Grow it until it counts as an established company itself and your licence becomes a charter: the company is yours, and so is your freedom. Run out of credit and you end up chipping ice in the Debtor’s Belt.
Build your company from nothing. Chart the sector, found stations, fill them with factories, labs and marketing, and research a tech tree for a better product.
Robots replace workers. Water, power and steel are your real costs, traded on a live marketplace where every deal moves the price.
Outsell, out-market and out-lobby the incumbents with sales agents, campaigns and sponsors, while GNN and the café never let you forget your offence.
A spiritual successor to the business sims of the early 2000s, with a clean modern look and a sense of humour.
Ingteractive writes the code, Emailzilla runs the email marketing and Sitezilla builds the sites. They power the group's own companies first. Ingteractive and Sitezilla also work for clients.
