What Collabstr is
Collabstr is a two-sided influencer marketplace with more than 1.1 million searchable creator profiles. Brands can buy packages directly from profiles or post campaigns that creators apply to with their pricing. Higher tiers add chat before hiring, advanced filters, audience reports, live post tracking, more campaigns, and team or agency controls.
The transaction layer is a core strength. Collabstr holds brand payment in escrow until the deliverable is approved, supports payments and compliance across 150 countries, and handles billing and tax documentation. Its brand plans are Free, $249 per month Pro on annual billing, $333 per month Premium on annual billing, and custom Enterprise. The published hiring fee is 10% on Free and Pro, 5% on Premium, and creators pay a separate 15% transaction fee when they withdraw earnings.
What Sponsorbook is
Sponsorbook starts before a marketplace transaction. It maps disclosed YouTube sponsorships to brands and creators, preserving the public video evidence behind the relationship. A creator or manager can research recent buyer activity, inspect who a brand has hired, save accounts to a list, watch for changes, and request the partnership contact for direct outreach.
The product is paid as research software rather than from the value of a sponsorship. Starter is $29 per month and Pro is $99 per month, with lower annual prices. Pro adds seats, CSV, a larger reveal pool, and MCP access for talent teams that want a shared or agent-assisted research process.
Marketplace demand versus owned prospecting
Collabstr creates a structured market. Brands can compare creator profiles, purchase defined packages, or publish a campaign and receive applications. Creators gain access to those opportunities plus a protected contracting and payment path. This works especially well for repeatable content packages and UGC briefs where the buyer wants a large pool of applicants.
Sponsorbook supports an account-based motion. The creator or talent team chooses companies with demonstrated YouTube spend, studies the brand's recent partnerships, and sends a direct pitch grounded in that evidence. Lists and watches make that motion repeatable, while the subscription remains separate from the economics of any deal.
The products can coexist. A creator can maintain a Collabstr profile and apply to suitable campaigns while using Sponsorbook to build a direct YouTube sponsor pipeline. The decision is about where to put the next hour: marketplace applications and delivery, or researched outreach to selected buyers.
