Case Study: One4Marketing achieves 60 new leads per month and 120% organic traffic growth with HubSpot

Dutch Entrepreneur Seizes Opportunity to Establish Inbound Marketing Agency in Untapped Market

One4Marketing, founded in 2011 by Driek Geurtsen near Utrecht, is an inbound marketing agency focused on Dutch SMB technology and ICT companies. Driek identified a recurring set of challenges—poor alignment between sales and marketing, high lead-generation costs and long sales cycles—and saw inbound marketing and HubSpot as an untapped opportunity in the Netherlands, prompting him to build the business as a HubSpot partner.

Using HubSpot tools and an inbound playbook—blogging, SEO, buyer-persona–driven content, event-based CTAs, email nurturing and a migration to the HubSpot COS—One4Marketing built a repeatable pipeline. The agency now generates about 4,000+ visits and ~60 new leads per month, saw organic traffic rise 120% after moving to the COS, has 80% of revenue on retainers, helped a client reach ~500 sales-qualified leads/month and 20–30% client growth, and is scaling rapidly toward HubSpot platinum.
