Collabstr is an influencer-marketing marketplace that simplifies brand-creator connections by enabling brands to search thousands of vetted Instagram, TikTok, YouTube, Twitter, Twitch, Amazon, and UGC influencers using detailed filters for niche, location, follower count, platform, and more; users can safely purchase and chat directly through the platform, with funds held in escrow until content is approved. Brands can post campaign briefs to a huge pool of creators, receive applications with pricing, and choose collaborators, while automated, one-click analytics track impressions, engagement, and performance in real time. No upfront costs, subscriptions, contracts, or hidden fees; search and hiring are free. Influencers are verified through audits of social behaviour and prior brand deals, and the platform supports secure messaging, custom offers, shipping coordination, and campaign management without the need for external tools.
