Floating Nuclear Reactors And Robot Auditors: Five Startup Deals You Missed

Bluecore Energy just raised an oversubscribed $50 million seed round — only two months after emerging from stealth with $10 million in pre-seed funding — to build nuclear reactors that float on barges.

The Long Beach, California-based startup attracted a long investor list led by Silverton Partners, with Slauson & Co., Harlem Capital, Black Angel Group and HartBeat Ventures participating. Bluecore is developing compact, water-cooled small modular reactors designed to operate aboard floating barges. The pitch: instead of spending years building a power plant and supporting infrastructure on land, manufacture the systems and ship them wherever electricity is needed.

"Our focus is simple. Create and deliver zero-emission energy as safely and quickly as possible," CEO and founder Kofi Asante wrote in a social media post. "Over 3 billion people live within an hour of water. We want to power them all."

Bluecore's first target is the Port of Long Beach, with other ports and power-hungry AI data centers among potential customers. The company says it is working with the Nuclear Regulatory Commission and the U.S. Coast Guard on certification. The raise lands amid a broader nuclear funding boom: nuclear fission startups alone pulled in roughly $2 billion in venture funding in 2025, per Crunchbase data.

$31M for AI-priced cement and steel

Saudi Arabia-based BRKZ secured $31 million in new capital last week, consisting of a $13 million Series B equity round co-led by Wa'ed Ventures — Aramco's venture arm — and 500 Global, plus an $18 million growth-debt commitment from Stride Ventures. The company has now raised more than $83 million, per Crunchbase.

The Riyadh startup runs a marketplace connecting construction companies with building-materials suppliers, handling sourcing, logistics and financing. The more striking number: BRKZ says it has amassed 38 million structured data points that power an AI pricing engine trained on roughly 40,000 requests for quotes. The company says 84% to 89% of its predicted prices come within 5% of the eventual transaction price.

Another AI agent reads photos of cement delivery notes sent through WhatsApp, matches them to orders and verifies deliveries — with roughly three-quarters processed without human intervention. BRKZ is riding a construction boom in Saudi Arabia even as investors stay selective about construction and property technology. Global proptech startups raised about $6.5 billion across roughly 640 deals in the first half of 2026, Crunchbase data shows — on pace to top last year's dollar figures even as deal count dips.

$24M for robots that mow, sweep and patrol

Santa Clara, California-based Viabot raised a $24 million Series A led by Walden International to scale its fleet of autonomous robots for outdoor commercial property maintenance. The machines combine autonomous navigation with attachments for sweeping, debris removal and landscaping — while conducting "soft security" patrols across large campuses.

Viabot deliberately avoids building general-purpose humanoids. Instead, it applies autonomy to repetitive jobs that property owners already pay contractors to do, operating on a "robot as a service" model. Kelly Coyne, founding partner at Grit Ventures, told Crunchbase News in 2021 that the startup targets the labor shortage in work that's often considered "dirty, dull and dangerous."

The market backdrop is unusually hot. Global venture funding to physical AI companies — robotics, autonomous vehicles, aerospace, drones, industrial automation and sensors — reached $47.4 billion across 521 deals in the first half of 2026, per Crunchbase. That's nearly 4x the $12 billion invested in the second half of 2025 and almost 80% above the year-ago period.

$10M to grade AI-controlled robots

Robocurve, a 3-month-old San Francisco startup, raised a $10 million seed round led by Initialized Capital, with participation from Y Combinator, Notable Capital, Halcyon Futures and Decasonic. The company wants to act as an independent third-party auditor for physical AI, testing how well frontier models control real robots and publicly reporting the results.

Robocurve is incorporated as a Public Benefit Corporation with a legal duty to independently evaluate the robotics capabilities of frontier AI systems. The company says AI labs don't dictate its research agenda, evaluation methodology or published results. Its own research has already found that general-purpose large language models can outperform specialized robotics vision-language-action models on some simple tasks.

The startup funds academic teams and supplies them with robot hardware to create open-source benchmarks. More than 200 institutions — including researchers from 19 of the world's top 20 universities, according to the company — have signed up, with $500,000 in combined funding plus free robotic arms on offer. Timing matters: robotics startups alone raised more than $21 billion globally in the first half of 2026, per Crunchbase, already eclipsing the nearly $16 billion raised in all of 2025. As powerful models move from screens into machines, verifying what they can and cannot safely do becomes a more consequential problem.

$5M so farmers can talk instead of type

Tellia raised a $5 million pre-seed round this month led by Revent for a voice-first AI platform built for farmers, agronomists and agricultural workers. The logic is simple: farmers don't spend their days at desks. Instead of filling out forms, users leave a voice note, send a WhatsApp message or submit a photo — and Tellia's AI turns that unstructured input into records tied to the correct field, crop and crew.

A livestock farmer might say: "Tellia, the vet just checked Herd 3. All clear, next health check due in 6 weeks, log that." A vineyard manager could ask about projected alcohol levels for a Cabernet lot based on this year's Brix and pH logs and get an instant answer.

San Francisco- and Paris-based Tellia was founded last year and says its technology is already deployed across 1 million acres, including at Campos Brothers Farms and Duckhorn wineries in the U.S., plus agricultural organizations in Europe. Grey Silo Ventures, Jeriko and Fund F also participated in the round. Agtech remains in a correction from its 2021 peak of $10.5 billion across more than 1,400 deals, Crunchbase data shows — which makes narrowly targeted, voice-driven AI applications a corner of the sector worth watching.
