Every venture round we've covered on Value Add Pulse -- seed through mega-rounds, with the VC take on each.
HappyRobot raised $150M at a $1.2B valuation just eight months after its Series B, with a16z and Eurazeo betting AI voice agents can expand from freight brokering into insurance, energy and airlines.
A consortium led by JPMorgan's Strategic Investment Group put $1B into Base Power at a $13B valuation, backing a company that leases home batteries and sells the aggregated capacity back to the grid.
Insight Partners led a $57M Series B for Convex, the reactive TypeScript backend now powering close to 2 million applications, with a16z and Spark Capital returning and OpenAI among its customers.

Fourteen startups raised billion-dollar-plus rounds in July, the highest monthly count on record, with $65B in combined capital led by a $10B round for Blue Origin.
US startup funding has already hit $415B through July across roughly 4,660 rounds -- a deal count that's not growing nearly as fast as the dollar total, meaning capital is concentrating into fewer, larger checks rather than spreading wider.
Qumra Capital led a $45M Series B for QuantHealth, which builds AI simulations of clinical trials so drug developers can test protocol designs before enrolling a single patient.
Beneath the mega-rounds, a steady stream of $10-30M seed and Series A checks is funding unglamorous back-office AI -- compliance, payroll, private-credit operations -- and that's where a lot of near-term enterprise revenue is actually landing first.
As attackers adopt AI-driven tooling, defenders are getting funded to match -- autonomous penetration-testing and AI-governance startups have both posted billion-dollar-plus valuations within the same month.
Defense tech has already pulled in more venture funding in 2026 than all of 2025 combined, and the checks keep landing even as public defense-tech comps wobble -- a split between private conviction and public market patience.
This week's largest venture checks all went to physical infrastructure -- nuclear power, chips, energy -- not software, and the dollar totals now dwarf what's going into application-layer AI startups.
Amsterdam's Ore Energy raised a $43M Series A from Plural and HV Capital to commercialize iron-air batteries that store renewable power for up to 100 hours at roughly a tenth of lithium-ion's cost.

Bending Spoons agreed to buy Airtable for $1.285B in its first acquisition since going public, a steep comedown from Airtable's $11B peak valuation in 2021 and its more recent $4B secondary-market price.
Sequoia led a $1B Series B for Valar Atomics at a $6B post-money valuation, tripling the mark it carried in April, weeks after the startup used a fission reaction to power an Nvidia AI chip.
Base Power raised $1B at a $13B valuation and launched Base Core, a 39.2 kWh home battery built in Austin -- a bet that AI-driven grid strain shows up first at the household level.
Baselayer raised a $20M Series A to automate fraud and risk checks for the 1,900+ banks and government agencies it already serves, betting the long-tail-institution market beats chasing megabanks.
P-1 AI raised a $50M Series A led by NEA for Archie, an AI agent that performs mechanical and electrical design work -- one of the few funding stories this week aimed at industrial engineering rather than software.
Base Power closed a $1B Series D at a $13B valuation, less than a year after its last billion-dollar round, to keep installing home batteries at roughly 100 per day.
TwelveLabs raised a $100M Series B co-led by NEA and NAVER Ventures to expand beyond video-understanding models into a full-stack agentic system combining perception, knowledge and reasoning for video.

Valar Atomics closed a $1B Series B led by Sequoia at a $6B valuation, tripling its April mark, weeks after its microreactor became the first in US history to power an Nvidia AI chip.
Lyzr raised a $100M Series B at roughly a $500M valuation after using its own AI agent, SivaClaw, to field questions from more than 130 investors and draft investment memos.
Base Power, founded by Zach Dell, raised another $1B Series D at a $13B valuation to keep installing backyard home batteries it never sells to customers -- it owns and monetizes them as grid assets.
Nuclear startup Valar Atomics raised a $1 billion Series B led by Sequoia Capital at a $6 billion valuation, tripling its valuation as it works to mass-produce small reactors to power AI data centers.
OLIX raised $312M to build a photonic inference chip that skips the HBM shortage bottlenecking Nvidia -- backed by Arm, Hudson River Trading and Reed Hastings, and a real signal that the AI chip market is finally getting a credible non-GPU challenger.
Bidbus's $15 million round for live-dealer car auctions and Smallest.ai's $13 million round for narrowly-focused voice models show seed-stage capital still backing unglamorous, defensible niches even as headlines chase AI infrastructure mega-rounds.
The Department of Energy converting a Cold War-era Kentucky uranium site into a $100 billion AI data-center complex, funded with private capital, shows federal real estate becoming a repeatable co-investment template for AI infrastructure.

Leopold Aschenbrenner's AI-focused hedge fund shrank from roughly $45 billion to about $10 billion in weeks after a leveraged momentum trade reversed -- proof a correct AI thesis doesn't protect against leverage-driven liquidation.
Function Health's $450 million growth round at a $2.5 billion valuation and Assured's $19 million Series A, closing within a day of each other, show healthcare AI capital concentrating at the very top and very bottom of the check-size range at once.
CAIS crossing a $2 billion valuation on 37% organic revenue growth, and a Cadre-founder-led AI startup landing $50 billion in design-partner AUM before its Series A, show fintech's unglamorous back-office infrastructure layer quietly compounding.
Three separate deals in the past week -- Nscale buying Anyscale, Okta buying Permiso, and IonQ closing on SkyWater -- show strategic acquisitions, not public listings, are becoming AI infrastructure's dominant exit path this cycle.
Horizon3 raised a $250 million Series E at a $2 billion valuation, betting that AI-accelerated attacks require continuous, autonomous penetration testing rather than the periodic audits most enterprises still rely on.
Menlo Ventures partner Matt Murphy says the firm is putting $3 billion in fresh capital to work on the belief that AI's current phase is a rare, short-lived land-grab window rather than a normal cycle to wait out.
A Marc Benioff-backed startup is building tooling that uses AI itself to solve the notoriously messy last-mile problem of deploying AI systems into real enterprise environments.

DataBahn's $40 million Series B for a platform that governs which enterprise data streams reach which downstream systems is a preview of how quickly "who gets to see the data" becomes its own funded category once AI agents get live production access.
Simile went from a $100 million Series A to a $200 million Series B at a $2 billion valuation in five months; Onyx Security raised its Series B four months after stealth -- evidence the time between funding rounds for hot AI startups keeps compressing.
K2 Space's $500 million Series D at a $6.8 billion valuation is the clearest recent proof that satellite manufacturing -- not just launch -- is where investors think the next infrastructure cycle gets built.
Glow's $180M endpoint-security raise and Onyx Security's $113M agent-governance round show AI-agent security has become one of 2026's fastest-funded categories, with multiple companies reaching $500M+ valuations within months of launch.
Crunchbase's new-unicorn tracker shows AI and robotics companies topping the list for consecutive months in 2026 -- 10 new unicorns in June alone, led by DeepSeek -- confirming unicorn creation is concentrated almost entirely in frontier tech.
Groundcover's $100 million Series C, betting that AI agents rather than human engineers are now observability tooling's primary users, is a preview of an entire category of dev-tools infrastructure getting rebuilt around AI consumers instead of people.
2026's largest venture rounds keep going to capital-intensive, physical-infrastructure bets -- fusion, satellites, thermal storage, AI compute -- rather than software, a pattern that has held for months and looks structural, not seasonal.
Global startup funding hit a record $510 billion in H1 2026, but the gains are concentrating in fewer, much larger checks -- a pattern this week's megarounds from Commonwealth Fusion, K2 Space and Antora Energy all reinforce.
This week's largest rounds -- satellites, thermal batteries, alt-investment infrastructure -- are one thesis: capital is chasing the bottlenecks between AI's compute buildout and its return on capital.
