Creator platform with a library of mini-apps for monetization, fan engagement, and digital product sales from a creator's link.
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.
a2z Radiology AI raised $20M in 2025 for its whole-body AI that simultaneously screens for 24+ conditions across CT scans — from incidental cancers to cardiovascular risk — in a single automated read.
a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
