Swiss AI startup Prem is raising $100M Series A amid sovereign AI boom
What's the deal? Prem AI, a Lugano-based startup that helps hedge funds, law firms, and other enterprises run AI models on their own private infrastructure, is raising $100 million in a Series A round, Bloomberg reported on June 18, 2026. The company is targeting a valuation of at least $500 million and expects to close the round in Q3 2026, according to founder and CEO Simone GiacomelliDealroom has a profile for this one.

Founded in 2023, Prem builds a platform that lets companies fine-tune models, analyse documents, and run API inference without sending data back to Prem's servers. It emphasises on-premise deployment, post-quantum encryption, stateless architecture, and Swiss jurisdiction.
The company previously raised a $14 million seed round from investors including Fan Zhang, co-founder of Sequoia Capital ChinaDealroom has a profile for this one. Try Dealroom →, and David Maisel, founder of Marvel StudiosDealroom has a profile for this one. Try Dealroom →.
Why now? Demand for sovereign AI infrastructure is surging — and recent US policy moves have made the case urgent. On June 12, 2026, the Trump administration ordered AnthropicDealroom has a profile for this one. Try Dealroom → to block foreign nationals from using its newest models. Anthropic disabled access broadly to comply.
The fallout was swift. JPMorgan ChaseDealroom has a profile for this one. Try Dealroom → cut off staff in Hong Kong from Anthropic's Claude models, and Goldman SachsDealroom has a profile for this one. Try Dealroom → made a similar move earlier in June, the Financial Times reported. For enterprises outside the US — or those handling sensitive cross-border data — the message is clear: relying on American AI providers carries geopolitical risk, and Prem's Swiss-jurisdiction pitch lands differently in that climate.
What could go wrong? The sovereign AI infrastructure market is getting crowded. Prem faces competition from European players like Mistral AI and Aleph Alpha, plus hyperscalers AWSDealroom has a profile for this one. Try Dealroom →, GoogleDealroom has a profile for this one. Try Dealroom →, Microsoft, and IBMDealroom has a profile for this one. Try Dealroom →, all of which now market sovereign-cloud offerings. A $100 million war chest is substantial for a Series A but modest against those rivals' resources. There is also the question of whether the current geopolitical pressure sustains: if US export controls ease, the urgency driving enterprise buyers toward on-premise alternatives could soften.
The signal: Gartner forecasts global sovereign cloud infrastructure-as-a-service spending will hit roughly $80 billion in 2026, with European spending alone expected to more than triple from $6.7 billion in 2025 to $23.1 billion in 2027. Prem's raise reflects a broader bet: that enterprises increasingly want AI capabilities without handing data — or strategic dependency — to foreign cloud providers.
