About
Resemble AI is a Toronto-based voice AI company that provides a comprehensive platform for custom voice creation, voice cloning, real-time voice conversion, and AI-generated audio detection. The company's voice cloning technology requires as little as a three-second audio sample to create a synthetic voice, and its real-time voice changer can transform a speaker's voice into a different AI voice during live calls. Resemble has built a strong differentiator in the AI safety space with its Resemble Detect product, which identifies AI-generated audio with high accuracy — addressing growing concerns about voice deepfakes in political content and fraud. The platform serves enterprises building voice experiences, game developers creating character voices, content creators, and security teams validating audio authenticity. Founded in 2019, Resemble AI raised funding from investors including Initialized Capital and has built partnerships with media companies and enterprise security organizations. It competes with ElevenLabs and Play.ht while occupying a unique dual position in both voice generation and audio authentication.
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.
About
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.
