Blaxel AI Secures $7.3 Million to Build Cloud Infrastructure for AI Agent Economy

Blaxel AI, Developer of Cloud Infrastructure for AI Agents, led by Paul Sinaï(CEO & Co-Founder), Thomas Crochet(Founder), Charles Drappier(Founder), Mathis Joffre(Founder), Nicolas Lecomte(Founder), Christophe Ploujoux(Founder), raised $7.3 Million in seed funding from First Round, Y Combinator, Liquid 2, Multimodal and several others.

Blaxel is an agent-native infrastructure platform built for the needs of autonomous AI systems. It features ultra-fast, secure sandboxes, an intelligent LLM gateway with unified access and failover, and serverless agent hosting that scales automatically. With built-in observability, snapshotting, and LLM-friendly interfaces, Blaxel enables AI agents to run securely, efficiently, and at scale, without the friction of legacy infrastructure.

During the YC batch, Blaxel supported fast-scaling AI agent startups like Human Behavior, Vybe, and Jazzberry—helping them go from prototype to production without infrastructure bottlenecks. Infrastructure was deployed across 16 global regions, processing millions of agent requests daily. One customer now runs over 1 billion seconds of agent runtime for millions of videos—at half the cost of typical serverless platforms—without managing a single server. Blaxel delivers terabytes of compute memory daily, eliminating the need for in-house DevOps and enabling AI companies to focus on growth.

As agent-based computing accelerates, legacy cloud platforms—built for human-driven software—are falling short. With Gartner predicting that 75% of app development will involve AI agents by 2028, a new infrastructure layer purpose-built for agents is becoming essential.
