Side-by-side comparison of AI visibility scores, market position, and capabilities
San Diego creator platform with hundreds of interactive mini-apps — tipping, digital art sales, recipe collections — enabling richer fan engagement from a single creator profile link.
About
Koji is a San Diego-based creator platform that provides a library of mini-apps that creators can add to their profile link for fan engagement, digital product sales, and monetization. Rather than a simple link-in-bio, Koji's mini-app model enables creators to embed interactive experiences — custom tipping experiences, digital art sales, recipe collections, watch party links, and hundreds of other creator-specific applications — all accessible from a single creator profile. Developers can build and publish new mini-apps on Koji's platform, creating a crowdsourced app store for creator tools that grows continuously with new monetization and engagement options. Koji serves creators across TikTok, Instagram, YouTube, and Twitch who want more interactive and versatile tools than basic link pages provide. The company raised $36M from investors including a16z, Jump Capital, and SWaN & Legend Venture Partners. Koji differentiates from Beacons and Linktree through its mini-app ecosystem that allows creators to offer unique, purpose-built fan experiences beyond standard digital product sales.
