Alarm bells ring over AI valuations; Databricks eyes $130B valuation; Revolut hits $75bn.

📣 Headlines

• Several investors and leaders are sounding the alarm on frothy AI valuations, warning the market may be overheating and posing systemic risks to tech companies and investors: investor calls AI 'dangerously overheated', DeepMind's Hassabis warns of a bubble and Google CEO Pichai cautions no company is immune.

• Some analysts push back that AI-related debt and hyperscaler buildouts are not a classic bubble, arguing bond markets reflect infrastructure growth rather than pure speculation (analysis).

• Mega-rounds and infrastructure bets continue: Databricks is reportedly in talks to raise at a $130B+ valuation, underscoring the broader theme that AI's next phase belongs to infrastructure.

• Large private-market activity persists with consumer-fintech strength as Revolut completes a share sale valuing it at $75bn, signalling continued appetite for late-stage rounds.

• Product teams should watch search behavior shifts—[consumers are moving from Google to ChatGPT], and startups like Peec AI raised $21M to help brands adapt to AI-powered search and GEO insights.

• Startups are productizing AI agents in verticals: security firms are shipping agent-native tooling with Secure.com debuting Digital Security Teammates while digital-health players scale AI therapy via M&A as Spectrum.Life buys Dr Jay to integrate an AI therapist.

• Talent and leadership are in flux as VCs prioritize hiring seasoned operators and execs to lead AI companies (VCs buying A-player C-suite talent), while top researchers exit big tech—Yann LeCun leaves Meta to start an independent AI entity and related coverage (BBC).

• Transportation and autonomy face a tougher funding environment: Crunchbase reports transportation dealmaking decelerating in 2025, and hardware-heavy startups show strain—Monarch Tractor warns of layoffs and a potential shutdown.

I've got a big favor to ask - keeping Blaze running isn't expensive, but it does all add up, so I'm asking readers like you to help, if you can, by joining the Patreon page. Nothing flashy, just a way for folks who find value in these newsletters to chip in a little each month.

If you are getting value from blaze, checking this out would mean the absolute world. But if you can't contribute, no worries - the newsletters keep coming either way. Thanks for reading and being part of this nerdy corner of the internet. All the best for the coming week - Alastair.
