Website development in Haarlem
Want a website built in Haarlem? Fifteen minutes from our office, we build for Haarlem businesses, from the creative city centre to the Waarderpolder business park.
Haarlem
Haarlem has a distinct character: many independent retailers, hospitality venues, creatives and service providers who live by their brand and atmosphere. Here a website can't be an afterthought but an extension of the shop or practice, with design that matches a city built on style.

A local partner from the region
Jongma Development is based in Hoofddorp (Walenburg 22), in the heart of Haarlemmermeer. That means short lines, personal contact and an agency that knows the local market. You work directly with the developer who builds your site, no account manager in between. And because we do it all ourselves, brand, website, SEO and AI, you never have to coordinate between separate agencies.
