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, and holds a BBA from Amsterdam. Brinkman Data is based in Amsterdam; the fieldwork is in Thailand and now covers four cities — Bangkok, Chiang Mai, Phuket and Pattaya. He is public-facing across three channels: YouTube @stanbrinkman (100+ published Shorts), 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.

Named buildings published, four cities

Step underwriting framework

Owned units, published in full
The engine screened 3,331 Chiang Mai listings in the March 2026 run alone. 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 the case study of the first unit. Read both before deciding whether this is for you.
Documented Purchases
The second unit I bought in Thailand
Chiang Mai. 2.15M THB purchase. Chanote title with foreign-quota freehold. Bought with his own capital, let, and published with every line item.

The first unit I bought in Thailand
Hang Dong. 2.85M THB purchase. Let direct, with no agent line. Deliberately the weaker of the two, published on the same line items so the pair can be compared side by side.
Read the weaker one →The $20 Protocol PDF. 7-day refund. No upsells.

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: four published city building files covering 271 named buildings, two verified deeds — the second unit I bought in Thailand and the first unit I bought in Thailand, both published with every line item — one published 5-step framework, 100+ 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.
