Top of the Morning
If you can't beat 'em, join 'em.
- That's the emerging consensus among private equity firms, which are building consortiums to work alongside the AI giants that are threatening to gut their portfolios.
Driving the news: OpenAI and Anthropic each are in talks with different PE groups to create something akin to enterprise AI consulting arms.
Zoom in: The OpenAI discussions are with such firms as Advent International, Bain Capital, Brookfield, and TPG, as first reported by Reuters.
- A source says that the effort likely would be structured as a majority-owned subsidiary of OpenAI, staffed by forward-deployed engineers who could both advise and implement. The PE firms would serve as minority investors and initial customers.
- Anthropic's discussions are with such firms as Blackstone, Hellman & Friedman and Permira, and were first reported by The Information.
- This one may be structured more like a joint venture, although no final decisions have been made. The talks began several months ago (i.e., before Anthropic's dustup with the Pentagon).
- It's unclear if either deal would require exclusivity, although it sounds unlikely.
The big picture: Private equity wants a seat at the AI table.
- Not only because portfolios are chock-full of software companies under siege, but also because many of their other portfolio companies don't really know how to best integrate AI.
- Yes, they could pay for OpenAI or Anthropic licenses. But then what? More than a few CEOs have lamented the time and money already lost on failed AI experiments.
- For the AI companies themselves, this is about pushing deeper into the enterprise — where the checks are bigger and the revenue is usually recurring.
- It's a whole lot faster for OpenAI and Anthropic to partner with PE firms than to approach each of their portfolio companies independently, and these efforts could be a test ground for non-PE enterprise clients.
Flashback: If all of this sounds familiar, you're perhaps old enough (I'm sorry, experienced enough) to remember Avanade — a JV formed in 2000 between Microsoft and Accenture to implement Windows and other Microsoft solutions into large enterprises.
- Not apples-to-apples, but similar enough. In that case, Accenture eventually acquired a control stake, with Microsoft retaining a minority position.
- Meanwhile, Accenture just yesterday completed its acquisition of Faculty, a VC-backed company in London that helps corporate clients adopt AI.
The bottom line: Private equity and Big AI need each other.
The BFD
Mastercard (NYSE: MA) has agreed to acquire London-based stablecoin infrastructure startup BVNK for up to $1.8 billion, including $300 million of contingent payments.
Why it's the BFD: Legacy payment providers are seeking to retain control over how money moves, even if the rails themselves change.
ROI: BVNK had raised around $100 million from Coinbase Ventures, Haun Ventures, Tiger Global, Visa Ventures, DRW Venture Capital, Avenir, and Scribble Ventures.
- It held takeover talks last year with both Mastercard and Coinbase, but seemed to be further along with Coinbase before the crypto exchange bailed in late fall. Mastercard, meanwhile, briefly kicked tires on BVNK rival Zerohash.
- One possibility is that Coinbase was more worried about revenue than is Mastercard, which primarily wants the technology.
The bottom line: "Mastercard isn't just partnering with crypto, it's buying its way into the stack to avoid being disintermediated." — Ryan Lawler, Axios Pro
