# 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.

- **Founded:** 2024
- **Headquarters:** San Francisco, California, United States
- **Founders:** Paul Sinai (Co-Founder & CEO), Charles Drappier (Co-Founder), Christophe Ploujoux (Co-Founder), Nicolas Lecomte (Co-Founder), Thomas Crochet (Co-Founder), Mathis Joffre (Co-Founder)
- **Team size:** 9 (approx.)
- **Products:** Sandboxes (Compute), Agent Drive (Storage), AI / Model Gateway, Serverless Agent Hosting, MCP Server Hosting
- **Notable:** Raised $7.3M seed led by First Round Capital within months of graduating YC X25., Processing millions of agent requests daily across 16 global regions., One customer runs 1B+ seconds of agent runtime per month (processing millions of videos) at ~50% lower cost than traditional serverless.

## Products & services

- **Sandboxes (Compute)** — Isolated microVMs that boot in milliseconds, resume in ~25ms, and cost $0 while idle. Support 50,000+ concurrent sandboxes with automatic hibernation and container-escape prevention.
- **Agent Drive (Storage)** — A distributed filesystem for multi-agent collaboration - persistent volumes that survive restarts and redeploys, retain data for years, and share state across sandboxes (up to 512 TB).
- **AI / Model Gateway** — A unified gateway consolidating access to multiple AI model providers with built-in caching, rate limiting, model routing and automatic failover.
- **Serverless Agent Hosting** — Framework-agnostic, GitHub-integrated deployment of agents as serverless APIs with automatic scaling and pay-per-use pricing.
- **MCP Server Hosting** — Hosting for custom Model Context Protocol servers that connect agents to external tools and data.
- **Programmable Networking** — Egress control with allow-listing, static IP per sandbox, secret injection via managed proxy, and geographic data-residency policies.

## Achievements

- Raised $7.3M seed led by First Round Capital within months of graduating YC X25.
- Processing millions of agent requests daily across 16 global regions.
- One customer runs 1B+ seconds of agent runtime per month (processing millions of videos) at ~50% lower cost than traditional serverless.
- Achieved SOC 2 Type II, HIPAA and ISO 27001 compliance.
- microVMs that resume in ~25ms and scale to 50,000+ concurrent sandboxes.

## Latest updates
