Brinkman Data Analytics is a one-person research operation run by Stan Brinkman, a Dutch BBA. The company is Dutch — Amsterdam — and the fieldwork is 18 months on the ground in Chiang Mai. The work is foreign-real-estate underwriting — analysing listings, rejecting most of them on the math, documenting the ones that survive. The catalog runs from a $20 protocol PDF to a $499 custom report. Three buyer reviews are quoted below verbatim. The case study at /case-studies/galaethong is documented down to the title deed. First paying client: May 30, 2026 — one Protocol and two commissioned $499 reports, Bangkok and Phuket, both delivered. This page exists so anyone verifying us has everything they need in one place.
Reviews
“Wasn’t expecting much for the price, but the yield breakdown is surprisingly dense. Worth it just for the data extraction framework alone. Straight to the point, no BS.”
“Exactly what I was looking to get started in buying a condo. I feel confident now that I’m not starting from scratch. Stan told me I could reach out to him if I ever got stuck — quite reassuring.”
“I used to spend a lot of time driving around Chiang Mai, scrolling real estate websites and visiting agents. This document convinced me to go further with Brinkman Data Analytics. It will save me a lot of time.”

Founder
Stan is Dutch, mid-twenties, holds a BBA from Amsterdam, and has lived in Chiang Mai for 18 months. He is public-facing across three channels: YouTube @stanbrinkman (29 published Shorts as of May 2026), Instagram @stan.brinkman, and TikTok @farang_stan.
He writes the methodology, analyses the listings, runs the math, and publishes the case studies. There is no team. There is no ghostwriter. There is no media kit pretending to be an institution.

Verified case study
The engine has analysed and scored more than 1,000 Chiang Mai listings over 18 months. Most get rejected — wrong title type, wrong oversupply curve, wrong CAM-to-yield ratio. One survived the math and closed: a 2.15M THB Chanote unit in Chiang Mai, foreign-quota freehold, documented to the deed.
The framework that produced that decision is the same 5-step framework sold as the $20 Thailand Underwriting Protocol. The full methodology is published, free, at /methodology. The case study with the bare numbers and adjacent disclaimer is at /case-studies/galaethong. Read both before deciding whether this is for you.
The Closed Deal
Chiang Mai. 2.15M THB purchase. Chanote title with foreign-quota freehold. One specific verified property, scored and bought after rejecting the rest.

Brinkman Data's first documented sales landed May 30, 2026 — one $20 Protocol and two $339 Custom Reports, Bangkok and Phuket, bundled at $549 and delivered. Before that date: zero. The audience is still small. The Instagram is months old under its current handle. The reviews quoted above are the reviews.
There is no growth chart. No client roster. No waitlist of 10,000.
What there is: 18 months of research, one verified deed, one published 5-step framework, 29 short videos, redacted pages of the delivered reports in the case studies, and a $20 PDF anyone can read in an evening. The brand is research-first, not marketing-first — the methodology was built before the catalog, not after.
If you are looking for a polished course-creator with five-figure testimonials, this is not it. If you are looking for someone showing the math in public before claiming the answer, this is.
