Blaxel
Blaxel is a San Francisco cloud infrastructure startup building what its founders call the 'AWS for AI agents.' Its platform runs autonomous agents on isolated microVMs that resume in roughly 25 milliseconds, alongside a distributed agent filesystem, programmable networking, and an AI gateway for model routing and failover. Founded in 2024 by a six-person team of repeat cloud builders who previously sold a data platform to OVHcloud, Blaxel went through Y Combinator's Spring 2025 (X25) batch and raised a $7.3M seed round led by First Round Capital. It already processes millions of agent requests daily across 16 regions.
OpenRouter
OpenRouter is a unified API gateway for large language models. Through a single OpenAI-compatible endpoint, developers can reach 400+ models from 60+ providers, with automatic routing, price comparison, and failover across vendors. It removes the need to maintain separate integrations for OpenAI, Anthropic, Google, Mistral and dozens of others, and now processes around 100 trillion tokens per month for more than 8 million users.
Alex Atallah
Alex Atallah is the CEO and co-founder of OpenRouter, the unified API and marketplace that routes developer requests across hundreds of large language models. He previously co-founded OpenSea, the NFT marketplace, where he was CTO before leaving in 2022 to build from zero to one again. A Stanford computer scientist and Palantir alum, he turned a side project that connected browsers to AI models into infrastructure now routing roughly 25 trillion tokens a week, and raised a $113M Series B in 2026.
