Most ad tech is built by people who never spent their own money.Mine wasn't.
Seven years buying media with my own budget at risk, in an operation that manufactures its own product and builds its own tracking.
Years buying media,
own money at risk

Layers of the loop,

On the circuit since 2022
Dubai, Bangkok, Barcelona, Budapest, Prague.
What he does
One loop, owned end to end.
Layer 01
Make it
PharmScale manufactures the supplements in Srebrenik — ISO 22000:2018 and ISO 22716 GMP, audited by TÜV Thüringen.
Layer 02
Sell it
PureNADH takes that output direct to consumers in the United States on a subscription model.
Layer 03
Buy the media
The paid media is bought in-house, with the company's own budget at risk rather than a client's.
Layer 04
Measure it
ScaleTrack, built inside Obscale, tracks and attributes every account across every platform.
None of the four started as a product for sale. Each began as something the operation needed and could not buy, which is still the only way he knows how to build anything worth selling.
The framework
Tracker
Debt
The compounding cost of every shortcut taken in measurement.
Symptom 01
A UTM convention nobody wrote down.
Symptom 02
A pixel that fires one step too late.
Symptom 03
A platform's own ROAS, never checked.
Each shortcut is rational the day it is taken. None of them are ever repaid, so they compound. The interest is paid in media spend, allocated against numbers that stopped being true months ago.
The companies
Four companies, one operation.
