Prem AI Eyes $100M Series A for Self-Hosted Enterprise AI Stack

LUGANO, Switzerland: Prem AI, a Swiss startup building a self-hosted enterprise AI platform, is looking to raise $100 million in a Series A funding round at a valuation of at least $500 million. The company expects to close the round during the third quarter of 2026.

If successful, the round would mark a 2.5x jump in the company’s valuation in roughly two years, reflecting growing enterprise demand for self-hosted AI solutions that keep data within a company’s own infrastructure rather than relying on third-party cloud providers.

Prem builds AI tools that run entirely inside customer infrastructure rather than the cloud. Customers include hedge funds, law firms, and other organizations handling sensitive data daily. The platform operates across private cloud, virtual private cloud, and air-gapped on-premise environments.

The fundraise coincides with the launch of Fluso, an encrypted AI workspace product. Fluso runs agents and automates tasks entirely inside the customer’s own infrastructure environment. The product targets enterprises that cannot send proprietary data to OpenAI or Anthropic.

The platform packages self-hosted model deployment with a ready-to-use application layer. Inference, security, and agent automation arrive as a finished product rather than a toolkit. Databricks and open-source projects from Meta and Mistral offer alternatives but require deeper engineering.

Founder Simone Giacomelli previously co-founded SingularityNET, the decentralized AI network. He started Prem in 2023 to focus on enterprise-grade self-hosted infrastructure. Prior backers include Jim Breyer of Breyer Capital, Index Ventures, and Sequoia Capital China co-founder Fan Zhang.

Marvel Studios founding chairman David Maisel also backs the company through earlier rounds. Maisel previously engineered the studio’s $4 billion sale to Disney in 2009.

“Enterprise intelligence must be owned, not rented,” says Prem CEO Simone Giacomelli.

The company previously closed a $14 million seed in April 2024 and a $6.1 million bridge round. Sovereign cloud spending should reach $80 billion globally in 2026 according to Gartner estimates. European spending alone should triple from $6.7 billion in 2025 to $23.1 billion by 2027.
