Inferact

Inferact is an AI inference infrastructure startup founded by the creators and core maintainers of vLLM, the most popular open-source LLM inference engine. Its mission is to grow vLLM as the world's AI inference engine and to make serving AI models effortless — as simple as spinning up a serverless database — by optimizing inference performance across diverse hardware, supporting emerging model architectures (mixture-of-experts, multimodal, and agentic), and expanding accelerator compatibility while keeping all optimizations flowing back to the open-source community. vLLM supports 500+ model architectures across 200+ accelerator types with 2,000+ contributors. This profile was surfaced as a venture-portfolio lead and enriched with verifiable public identity and domain-security signals; the company does not yet publish a public API, developer portal, or specification.

Inferact is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine Learning, LLM Inference, and Infrastructure.
