About

Mainstage is a performance UGC campaign platform for brands and agencies. Run campaigns in two lanes: creators can repurpose podcasts, streams, demos, webinars, founder footage, and other existing media into short-form clips, or make original reviews, walkthroughs, comparisons, interviews, skits, and product posts from a brief. Brands define the format, claims, disclosures, usage rights, budget, approval rules, and payout model before work starts. They can invite creators, accept applications, or use Mainstage Concierge to source a cohort. Mainstage keeps briefs, creator rosters, submissions, approvals, verified views, funded creator payouts, and reporting in one workflow. Campaigns can pay per approved post, per 1,000 verified views, or through a defined hybrid. Platform fees scale with monthly campaign spend, and managed campaign support is available.

About

Sponsorbook is a YouTube sponsorship intelligence platform for creators and talent agencies. It tracks disclosed brand deals across YouTube and turns them into a searchable database of sponsors, creators, sponsored videos and decision-maker contacts. Add a channel to find brands already paying creators in a similar niche and size range, review the evidence behind each match, and see which sponsors are actively spending. Creators can build targeted prospect lists and pitch brands directly. Agencies can research opportunities across an entire roster and share the work with their team. Sponsorbook takes no commission on deals.
