Yellowgrape
Company Overview
Yellowgrape is a Dutch ecommerce growth agency focused on improving commercial performance through experimentation, marketing, data and customer-journey optimization. Rather than concentrating on one commerce platform, the agency works across the funnel, helping established online retailers identify where acquisition, trust, merchandising or checkout behavior limits growth.
Its published cases emphasize measurable testing and full-funnel programs. Services represented in the portfolio include conversion optimization, analytics, lifecycle and campaign strategy, personalization and experimentation, making Yellowgrape most relevant to merchants that already have meaningful traffic and want a systematic way to turn more of that demand into revenue.
Topbloemen is a strong example: experiments around delivery-cost transparency reduced checkout abandonment by 5.53%, while a later value-message variation lifted conversion by 1.14%. The agency also publishes a Black Friday program for Amac focused on replacing promotional noise with a more deliberate growth approach. Together the cases demonstrate evidence-led ecommerce optimization rather than one-off redesign work.
