Building AI Knowledge Systems for Expats and the Organizations That Serve Them

From Personal Pain to Scalable Solution

We moved to Valencia and immediately hit the wall that every expat hits: bureaucracy that assumes you speak fluent Spanish, have Spanish credit history, and understand systems that locals learn from birth.

NIE appointments booked months out. Banking requirements that varied by branch. Housing applications rejected for lack of Spanish payslips. Healthcare registration that required documents we didn't know existed.

We spent hundreds of hours figuring it out. Talked to other expats. Built checklists. Made mistakes. Eventually, we had knowledge that could save others the same pain.

That's when we built MyCityZen—29 AI agents encoding everything we learned. Not generic internet knowledge, but specific, validated guidance for Valencia: which NIE office is fastest, which banks actually work with foreigners, which neighborhoods have English-speaking pediatricians.

MyCityZen proved the concept. Now we build the same kind of specialized, ethical AI knowledge systems for organizations: international schools helping relocating families, property agencies guiding foreign buyers, accelerators onboarding international founders.
