Delos Data, which develops network chips and software to connect AI chips in a data center, raised $100M from Matrix, Playground, Socratic Partners, and others

Arcee AI, which develops open-weight models in the US, raised a Series B at a $1B pre-money valuation; a source says Arcee raised at least $150M

A $1B pre-money for a 2023-founded open-weight lab that reportedly trained four models for $20M says the market is now pricing capital efficiency and IP control, not just raw scale. If you're an enterprise buyer, expect more credible non-hyperscaler options for custom models—and more leverage in negotiations around data residency and licensing.

Cohere and Aleph Alpha sign a definitive merger agreement; the combined company will operate as Cohere, with Aleph Alpha co-CEO Ilhan Scheer becoming Cohere COO

A Cohere–Aleph Alpha merger creates a transatlantic enterprise AI vendor with both North American and EU sovereignty credentials—exactly what large regulated buyers have been asking for. If you're standardizing on a model provider, this combination strengthens the case for a dual-jurisdiction partner over a purely US- or EU-centric one.
