Company Overview

About Inferact

Inferact commercializes vLLM, the most widely used open-source LLM inference engine, for enterprise deployments. The company provides a managed platform, premium performance optimizations, and enterprise support around the open core, targeting teams that need high-throughput, cost-efficient inference at production scale.

Business Model & Competitive Advantage

In January 2026, Inferact raised a $150M seed round at an $800M valuation led by Andreessen Horowitz and Lightspeed Venture Partners — an unusually large seed that reflects investor enthusiasm around the shift from model training to inference economics.

Competitive Landscape 2025–2026

The platform competes directly with Together AI, Fireworks AI, Modal, and Anyscale on latency, throughput, and cost per token, while leveraging the brand and community around vLLM. Target customers include AI-native SaaS, model providers running custom fine-tunes, and enterprises self-hosting open-weight models.
