The 9:16 auction: why vertical needed its own ad stack
Display auction logic was written for a rectangle you scroll past. Vertical is a thumb, a heartbeat and fourteen seconds of undivided attention. We rebuilt the bid path around that — an edge auction, a Bangla context model, and a yield curve that prefers the viewing experience over the last two percent of CPM.

Building the creator studio that doesn't feel like work
Light, sound and ritual in a one-desk Dhaka room that ships a finished episode every day — and the three pieces of gear that turned out to matter.
BanglaReelsCreator economics
What a creator actually earns
Ads, brand deals, subscriptions and affiliate, broken out for a real month on a real account — gross, net, and the gap between them.

Measuring what matters in 14.3 seconds
Retention in short form is a story told in frames, not minutes. How we built a watch-time model that reads a Bangla episode the way a viewer does.

A day with Riya: 2.3M followers, one phone, no manager
What sovereignty looks like when a nineteen-year-old from Rajshahi monetizes her own audience without routing a single taka through Mumbai.

Four cities, not one country
Dhaka, Chittagong, Khulna and Sylhet behave like four different markets. Treating Bangladesh as one targeting unit was costing us a third of our CTR.

Why we don't buy brand-safety lists
A keyword blocklist written for English quietly defunds half of Bangla culture. We built a context model instead, and published what it refuses.

The dashboard we ship to creators
Completion rate, watch time and retention, in the two-week window a creator can actually act on. What we put on it, and what we took off.

Watercolour as a system: designing the house wash
How one painted mountain became a design token — and the rules that keep it from turning every venture page into the same page.
Sovereign HouseThesis
Regional is not a filter. It is the product.
Why Dhaka-first product thinking beats a translated San Francisco roadmap every single time, with three places we learned it the expensive way.

Prebid for 9:16: what we broke to make it fast
Our header-bidding wrapper had to forget almost everything it knew about desktop. The four modules we deleted, and the one we rewrote twice.
