What CreatorDB is
CreatorDB is a broad influencer intelligence product. Its platform and API cover more than 30 million creator profiles across YouTube, Instagram, and TikTok, with audience demographics, engagement, sponsorship history, estimated creator pricing, niches, content signals, and verified creator emails. The company also publishes a brand directory and bidirectional sponsor lookup.
The technical surface is a major part of the proposition. CreatorDB provides a REST API and a first-party MCP so brands, developers, platforms, and agency teams can integrate creator and sponsor data into their own systems. Platform access spans Free, Pro, Premium, and Enterprise tiers; the free tier gives full access to five creator profiles before restrictions apply, and API access is approved case by case.
What Sponsorbook is
Sponsorbook turns the YouTube side of the creator-brand graph into a finished research workflow. Search sponsoring brands, inspect the creators and source videos associated with each one, review current activity, save prospects to lists, watch for changes, and request the relevant partnership contact. The record is shaped for a creator or manager deciding who to pitch next.
Pro also includes MCP, but the goal is workspace parity rather than a raw data product. An authorized agent can work with the customer-visible catalogue and workspace within plan limits. That keeps the interface aligned with the same brands, evidence, lists, and contact actions a person uses in the web product.
Platform data versus a focused research workspace
CreatorDB is the more expansive data platform. Multi-platform profiles, audience demographics, long time series, natural-language search, creator price estimates, API access, and an agent interface support teams that need to build influencer data into another product or internal operation.
Sponsorbook concentrates on the creator-side YouTube buying question. The public source remains attached to the sponsorship relationship, and the surrounding workflow covers prioritization, monitoring, optional channel fit, and a route to the partnership contact. It is sold as a complete workspace with public prices rather than an integration project.
An agency can reasonably use both. CreatorDB can supply broad multi-platform creator intelligence and technical integration. Sponsorbook can give the talent or sales desk a dedicated view of YouTube sponsors, recent evidence, saved buyer research, and the next contact action.
