Managing Partner, @stevebrotman featured in @FortuneMagazine discussing one of the most important conversations in finance and technology today: how AI and private markets could reshape wealth creation for decades to come. As AI investment opportunities continue to concentrate in private markets, the conversation around access, ownership, and long-term economic impact is only becoming more important.

AI now accounts for roughly half of total VC market value, and @stevebrotman sees it as a long-term structural shift, not a bubble. In a recent Institutional Investor feature, the Alpha Partners Managing Partner compared today’s AI boom to the industrial revolution, noting that “every company will be an AI company” in some fashion. Steve also shared that nearly 70% of Alpha Partners’ third fund is invested in AI-related companies. Read more: institutionalinvestor.com/ar…

Excited to share that we’ve raised $300M in our Series B round, led by @radicalvcfund, bringing our total funding to more than $450M, with leading technology companies joining as both customers and investors. We continue accelerating the path to AGI through our two core pillars: ultra-optimized infrastructure for AI workloads, and realtime world models built on top of it. Today, we’re also launching DOS (Decart Optimization Stack) 2.0 – our next-generation inference and training platform, delivering over 1,600 tokens per second for agentic inference and over 100 FPS for world models across major hardware platforms. Alongside DOS, we will launch new versions of our world models in the coming weeks: Lucy, for immersive realtime experiences, and Oasis, for physical AI. Grateful to our partners, customers, and backers across media & entertainment, Physical AI, chips, hyperscalers, and the broader AI ecosystem. @radicalvcfund, @Adobe, @alphaptrs, @amazon and @awscloud, @Atreidesmgmt, @benchmark, @eBay, @nvidia, @sequoia, @Toyota, @valor, @orenzeev; Andrej Karpathy, Michael Eisner, Yamauchi-No.10 Family Office, Moritz Baier-Lentz and more.

In a recent @BusinessInsider article on this year’s @MilkenInstitute Global Conference, Alpha Partners Managing Partner @stevebrotman discussed why the event remains one of the most important fundraising and networking gatherings in finance. “This is the biggest aggregation of allocators in the world,” Brotman said. As Steve notes in the piece, the conference’s continued relevance reflects a larger private-market dynamic. Institutional investors are increasingly focused on private technology exposure, particularly as companies like Anthropic and Anduril continue to reshape how allocators think about venture capital and AI-driven value creation. “If you’re an investor and you’re not in private tech, you’re dust,” Brotman said. “We’re in an AI super cycle.” Read the full Business Insider article here: businessinsider.com/inside-t…
