Raised $60M (seed + Series A) from a16z, Sequoia, Menlo Ventures. $500M+ valuation. 1M+ developers. $100M+ annualized inference spend routed. De facto standard LLM router.
OpenRouter is the de facto standard LLM routing layer — sitting between applications and every major AI model provider (OpenAI, Anthropic, Google, Meta, Mistral) to route inference requests based on cost, speed, and capability. The company has raised $60 million across seed and Series A financing from Andreessen Horowitz, Sequoia Capital, and Menlo Ventures at a $500 million+ valuation, with 1 million+ developers routing $100 million+ in annualized inference spend through its platform.
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.
