Swiss Startup Prem AI Raises $100 Million to Build Sovereign Enterprise AI

A Swiss startup that lets hedge funds and law firms run artificial intelligence on hardware they control is raising $100 million, a Series A round that has become the clearest signal yet that the panic over who owns enterprise AI is now a fundraising thesis.

Prem SA, the Lugano-based company building tools for private and self-hosted AI deployment, is in the market for a $100 million Series A at a valuation of at least $500 million, Bloomberg reported on June 18, 2026. Founder and chief executive Simone Giacomelli told Bloomberg the company expects to close the round in the third quarter. If it clears that target, Prem's valuation will have jumped roughly 2.5 times in about two years, and its total funding will push past $120 million.

The timing is not subtle. Prem's pitch, in Giacomelli's words, is that "enterprise intelligence must be owned, not rented" — and the market spent the preceding week proving his point.

A Round Built on a Bad Week for Rented AI

On June 12, the U.S. ordered Anthropic to block foreign access to its newest Fable 5 and Mythos 5 frontier models, and the company disabled them the next day, saying it was the only way to comply with the export controls. The disruption rippled outward fast. JPMorgan Chase cut Claude access for staff in Hong Kong after concluding Anthropic's licensing terms excluded Greater China, and Goldman Sachs had made a similar move earlier in the month.

For a regulated firm, that sequence is the moment a model stops being a tool and becomes a dependency controlled by someone else, in another jurisdiction, subject to a policy change announced overnight. That is precisely the anxiety Prem sells against.

Founded in 2023, Prem makes software for running AI models on a customer's own infrastructure rather than a cloud provider's. Customers fine-tune models, analyze documents, and run inference inside their own environments, and the company says the data never returns to Prem's servers. Its early targets are the buyers with the most to lose from a leak: hedge funds, where the value proposition is competitive intelligence that stays inside the firm, and law firms, where it is privilege-protected work product that never touches a third-party cloud.

Alongside the raise, Prem unveiled Fluso, an encrypted workspace for running AI agents and automating work that operates wherever a customer's data already sits — a private cloud, a virtual private cloud, or a fully air-gapped, on-premise system. Fluso uses open-weight models, so every parameter can be audited, and the company says none of the customer data touches a training pipeline.

Giacomelli is not new to frontier AI. Before Prem, he helped start SingularityNET, the decentralized AI network — a background in distributing control rather than concentrating it that maps neatly onto the sovereignty pitch he is now making to enterprises.

The Sovereign-AI Trade Goes Mainstream

Prem is not raising into a vacuum. The same week, the broader market underscored how much capital is chasing the self-hosted, jurisdiction-aware corner of AI. Cybersecurity and sovereign-AI firm Dream raised $260 million, AI inference provider Baseten was reported to be raising $1.5 billion, and a string of smaller infrastructure rounds closed alongside them. Sovereign AI has graduated from a policy panel topic into a line item investors actively want exposure to.

The underlying numbers explain the appetite. Gartner has forecast roughly $80 billion in global sovereign cloud infrastructure-as-a-service spending in 2026, with European spending alone projected to more than triple, from $6.7 billion in 2025 to $23.1 billion in 2027. What was once framed as a question for nation-states — who controls a country's compute and data — now applies to any firm whose competitive edge lives in its proprietary information.

Switzerland is part of the sell. The country holds an EU adequacy decision, so data can move to and from the bloc, and a rewritten Swiss privacy law has applied since September 2023. None of that puts a Swiss company entirely beyond the reach of foreign governments, but for a buyer trying to reduce reliance on U.S. cloud vendors, Swiss jurisdiction is a concrete fact an auditor can sign off on.

Prem's backers reflect that cross-border thesis. Earlier rounds — a $14 million seed in April 2024 and a $6.1 million bridge at a $200 million valuation — drew Fan Zhang, co-founder of Sequoia Capital China, and David Maisel, the founding chairman of Marvel Studios, among others.

The competitive field is crowded and well-funded. France's Mistral AI has leaned hard into European infrastructure, including $830 million in debt financing for a data center near Paris. Germany's Aleph Alpha built its name on sovereign deployments for governments. And the hyperscalers — Amazon Web Services, Google, Microsoft, and IBM — are all pitching their own locality-bound options to keep regulated customers from leaving.

What to Watch

The open question is whether Prem closes at the targeted $500 million valuation in the third quarter, and which lead investor anchors the round — details the company had not disclosed as of mid-June. Just as important is whether Fluso converts the sovereignty pitch into recurring revenue, or whether enterprises decide a hyperscaler's sovereign-cloud tier is good enough. For now, the export-control shock has handed Prem its strongest possible argument, and a $100 million round is the market's bet that the argument holds.
