Pick the globe, the moon or the trophy. Or type ATLAS.
Who pays for YouTube.
ATLAS is my side project: a dataset of 10M+ YouTube videos, each with segment data down to the second, and a pipeline that works out who paid for every sponsor read. Every figure here is from my public posts. The full September 2026 report goes to agencies who ask.

I helped grow Moon 100×.
I joined as researcher, scriptwriter and video planner when the channel had 10,000 subscribers. It passed a million in 2023 and has 1.8M subscribers · 375M views today.
- Built the framework for a repeatable, high-retention video essay.
- Researched topics, keywords and retention tactics against the algorithm.
- Outlined and edited scripts with the writers, cutting everything boring.
The Sponsor Game.
Six rounds on real ATLAS numbers: three higher-or-lower, three estimates. Everyone gets the same set today, and the best scores go on the board.
The record.
Economics by training, YouTube by trade. Open to creator-economy strategy and insights roles in 2027.
