A $2.2B+ week across 24+ disclosed deals, anchored by Vestwell's $385M fintech mega-round and Temporal's $300M bet on agentic AI infrastructure. Code Metal hit unicorn status. On the M&A side, Danaher's confirmed $10B Masimo acquisition led over $13B in deal value. Fund closes from Battery Ventures ($3.25B) and Peak XV ($1.3B) showed LPs remain aggressive in high-conviction areas.
AI infrastructure becomes the main event. Three of the week's five largest rounds went to companies building the plumbing beneath AI: Temporal ($300M for durable execution), Heron Power ($140M for solid-state transformers powering data centers), and Code Metal ($125M for verifiable code translation). The thesis is clear: as AI agents proliferate, the reliability, energy, and correctness layers are where the value accrues. a16z led or participated in two of the three.
Fintech and savings infrastructure attract institutional capital at scale. Vestwell's $385M raise (Blue Owl + Sixth Street) was the week's largest round, reflecting a deeper shift: institutional investors are backing the rails that power American retirement and savings. With $200M+ ARR and $50B in assets, this is infrastructure investing. Meanwhile, inKind ($450M), Jump ($80M), and Stacks ($23M) show AI-driven fintech covering everything from restaurant commerce to financial advisor workflows to enterprise accounting.
Defense, security, and hard tech consolidate. Code Metal's 5x valuation jump (defense AI for code translation), Vega Security's $120M (three rounds in one year), ChipAgents ($50M for semiconductor AI), and Terra Industries ($22M for African defense) all tell the same story. Add Danaher's $10B Masimo acquisition and XTEND's $1.5B defense drone SPAC, and the week paints a picture of capital aggressively flowing into physical-world tech with government and enterprise customers.
The backlash counter-narrative grows louder. Google warned LLM wrappers face survival pressure. Public AI skepticism outpaced adoption. Bernie Sanders called for a data center moratorium. And roughly 90% of firms reported no AI productivity gains. Yet the capital kept flowing: the tension between VC optimism and mainstream doubt defined the week's mood on X, landing somewhere between "cautious" and "selectively bullish."
The digital savings infrastructure platform doubled its valuation to $2B with a massive $385M raise. With $200M+ ARR, $50B in assets, and 2 million active savers across 500,000+ businesses, Vestwell is becoming the backbone of America's workplace retirement and savings economy.
The durable execution platform doubled its valuation to $5B with an a16z-led raise to power reliable AI agents in production. Temporal's infrastructure underpins agents at OpenAI, Anthropic, Netflix, JPMorgan Chase, and Stripe. As enterprises deploy agentic AI, Temporal is positioning itself as the critical reliability layer.
The ex-Tesla SVP's solid-state transformer startup raised $140M to build a 40-gigawatt automated U.S. manufacturing facility. Heron Link replaces century-old transformer designs with modular, software-integrated power electronics, solving a critical bottleneck for AI data centers and renewable energy.
The AI code translation startup hit unicorn status at $1.25B, up 5x from its $250M Series A three months ago. Code Metal's neuro-symbolic platform combines LLMs with formal verification to produce provably correct code translations for defense and aerospace customers including the U.S. Air Force, RTX, and L3Harris.
The Israeli cybersecurity startup reached $700M valuation with its third round in under a year. Vega replaces traditional SIEM with "Security Analytics Management," running analytics where data already lives. Founded by Unit 8200 veterans in January 2024, Vega has raised $185M total in just two years.
The AI operating system for financial advisors raised $80M, now used by nearly one in ten U.S. financial advisors. Jump automates meeting notes, compliance docs, CRM updates, and follow-up emails for teams at LPL Financial, Cetera, and Focus Financial.
The AI observability platform hit an $800M valuation. Founded by Ankur Goyal (ex-Impira/Figma AI lead), Braintrust helps teams at Notion, Replit, Cloudflare, Ramp, and Dropbox evaluate, log, and monitor AI agents in production with a custom database optimized for massive trace data.
Confirmed at $180/share cash. Adds pulse oximetry and patient monitoring to Danaher's diagnostics portfolio.

Oversubscribed quantum/physics fund, more than doubled its inaugural fund.
The week's consensus: the era of "fund everything" is ending, but the era of "fund the right things at scale" is accelerating. Capital is bifurcating between infrastructure plays with proven revenue (Vestwell, Temporal, Jump) and high-conviction frontier bets (Code Metal, Heron Power). The backlash narrative is real but hasn't slowed deal flow. The biggest tension: investors publicly acknowledge AI's ROI problem while privately deploying at record pace.
