Custom AI Tools for Marketing and Creative Agencies
Yellow House Digital builds custom AI tools for marketing and creative agencies. It is the studio of Jordi Buskermolen, who co-founded and ran a thirty-person agency for twelve years before building AI tools full time. The work is remote, with a UK and European client base.
What gets built
The tools are specific, not generic AI features bolted onto a dashboard. Recent work includes MCP servers that let AI assistants use a product's own data safely, lead-screening tools that read and rank inbound enquiries, and research instruments that gather and structure what a team would otherwise trawl by hand.
Some agencies want a tool. Some want a website or an application with AI built into it from the start. Both are the same job here: understand the workflow first, then build the smallest thing that changes it.
Built by someone who ran an agency
Yellow House Digital is run by Jordi Buskermolen, who co-founded and ran This Page Amsterdam, a thirty-person digital agency, from 2009 to 2021. The tools are shaped by having sat on the other side of the table - knowing how agency work is won, scoped, and delivered, and where the repetitive drag actually lives.
That background is why the writing on this site spends as much time on how agencies operate as on the technology.
Methods published in the open
Every method is published - papers, playbooks, and working tools an agency can read before committing. There are no gates and no email walls. An agency can judge the work first, which is the point.
Questions
- What does Yellow House Digital build for agencies?
- Custom AI tools - MCP servers, lead-screening tools, research instruments - and websites and applications with AI built in. The starting point is always the agency's own workflow, not a generic template.
- Who is it for?
- Marketing and creative agencies: design, branding, SEO, and digital shops. It suits agency owners who want a tool that fits how they already work rather than a product they have to work around.
- Do you work with UK agencies?
- Yes. The work is fully remote, with a UK and European client base. Location is not a constraint.
- What makes a tool "custom" here?
- It is built around one agency's actual process. The scope is the workflow you want to change, not a feature list from a roadmap.
- How do we start?
- A short conversation about the workflow you want to improve, then a one-page plan with scope and next steps before any building begins.
