Your audience moved.
Brand Efficiency and Quality control didn't.

YouTube is the world's largest video platform and one of the hardest for premium brands to use confidently. Inventory quality is uneven. Standard brand-safety tools work at the keyword level.
Pre-built categories miss what matters.

2.7B

YouTube monthly users — the world's largest video platforms

30%

77%

One curation engine.

Custom-built per brand for the many surfaces of YouTube.

YouTube isn't one platform — it's many surfaces, each with different rules: Shorts, long-form, kids content, non-skippable ads.
Siever curates each one on its own terms.

Powered by Google's Audience Insights API

Audience Insights API

Deep audience and channel selection that goes beyond metadata. We start with who you want to reach, not pre-built categories.

Gemini-powered scoring across 4 criteria

Custom curation model

We re-run analysis on demand to build scoring criteria specific to each client's brand. Agility, not volume — that's our edge against competitors with fixed lists.

Curation that's about your brand,
not someone else's category.
