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

Rey is an AI assistant for creator marketing teams that works in Slack to help manage recurring campaign operations. It can prepare creator performance reports covering GMV, orders, active creators, and content output; assemble campaign plans, terms, and outreach drafts for review; track creator partnerships and samples, highlighting delayed shipments, overdue follow-ups, and missing posts; and capture meeting decisions, owners, and next steps. Rey also analyzes advertising performance and suggests possible budget changes without making changes to ad spend. Teams can set workflows and review points, retaining approval over work that requires human judgment. The service is designed for brands and teams managing creator programs, particularly ecommerce businesses that coordinate campaigns, samples, content, and results across creators.
