Video Channel Sponsor Prospector (official platform API)
Find small and mid-size video channels by topic, language and upload frequency through the official YouTube Data API, and export a shortlist for sponsorship outreach.
Economics
- Pricing example
- $19 for 200 channel lookups (first 20 free)
- Daily math
- 1 pack a day x $19 = $19/day; a few extra packs a month take the average past $20/day.
- Target if you hit the daily math
- Target: $550 - $800 / month if the daily math is hit
Audience and urgency
Audience: Small brands, app makers and agencies looking for niche creators to sponsor, including brands targeting Malaysian and SEA audiences.
Urgency: Small brands can't afford big creators but struggle to find active mid-size channels in their niche. Searching by hand mixes in inactive channels and very large ones.
