September

What September does

September (legally September Digital B.V.) is a privately held Dutch digital agency founded in 2013 and headquartered at Steenovenweg 8, Utrecht, Netherlands. The firm operates as a B2B professional services provider, delivering custom websites, web applications, digital platforms, mobile apps, and digital strategy to organizations across education, environment, healthcare, media, fashion, and cultural sectors. Its client portfolio skews toward mission-driven and impact-oriented brands — including Super Chill (a mental resilience program reaching a stated 10 million European children), Aalberts Bouw (a 350-year-old construction firm), Emergence Magazine, VPRO, Natuur & Milieu, Edukans, and Zorgverzekeraars Nederland — indicating deliberate positioning around purpose-led organizations rather than generic commercial accounts.

September's core technical stack combines WordPress (powered by its proprietary Alfred framework, used in approximately 90% of website projects), Laravel for complex custom applications, Vue.js and React Native for front-end and mobile work, Elasticsearch for content indexing and search, and JavaScript/PHP for core development. The Alfred framework differentiates the firm's content-site work by embedding SEO optimization, speed tuning, and automated weekly updates; on the application side, September has built bespoke solutions such as a websocket-based state calculator for De Bovenkamer's multi-device classroom system and a custom audio player supporting Emergence Magazine's storytelling formats. Beyond delivery, the firm offers a Discovery Phase, UX research, digital strategy, and ongoing maintenance/SEO/growth services, and runs an internal innovation initiative called September Labs.

The agency monetizes through project-based professional services engagements, scoped and priced per project, with no publicly disclosed pricing and no productized SaaS offering. Its go-to-market is sales-led and partner-driven: Managing Director & Partner Julian and Digital Director & Partner Jan-Maarten serve as primary client-facing contacts, and new work is initiated through discovery workshops and direct outreach. The firm is partner-owned with three named partners (Julian, Jan-Maarten, Daan) and no disclosed venture capital or private equity backing; it is a member of the Dutch Laravel Foundation and maintains recurring co-development partnerships with creative studios such as Studio Airport, Ouruse, NOA Collective, and More Than Games.
