Crunchbase Picks Five Under-the-Radar Rounds: Floating Nuclear, Robot Scorecards, Farmer Voice AI
Crunchbase regularly selects a handful of underreported but noteworthy funding rounds. This edition features five companies across nuclear energy, construction, robotics, and agriculture.
Their common thread: applying AI and automation to concrete industrial problems rather than pure software.
Bluecore Energy, a Long Beach, California startup, raised $50 million in seed funding led by Silverton Partners. It develops compact water-cooled small modular reactors designed to operate on floating barges.
Instead of spending years building a new land-based plant and supporting infrastructure, the company aims to manufacture the system and ship it to where power is needed. CEO Kofi Asante said more than 3 billion people live within an hour of water, and the company wants to supply them with power. Its first target is the Port of Long Beach; other ports and AI data centers are potential customers.
Bluecore is working with the U.S. Nuclear Regulatory Commission and Coast Guard on certification. Nuclear momentum is rising: fission startups raised about $2 billion in 2025, while clean tech, EV, and sustainability startups raised about $15 billion in H1 2026.
Robocurve, founded three months ago, raised $10 million in seed funding led by Initialized Capital, with Y Combinator, Notable Capital, and others participating. It positions itself as an independent third-party auditor of physical AI, testing how frontier models control real robots and publishing results.
Its research found general-purpose LLMs can outperform specialized robot vision-language-action models on some simple tasks. Registered as a public benefit company, Robocurve is legally obligated to independently evaluate frontier AI systems' robotics capabilities and report publicly; it says AI labs cannot set its agenda, methods, or publication.
It funds academic teams and provides robot hardware for open-source benchmarks; over 200 institutions have joined, with $500,000 in total funding and free robotic arms. Robotics startups raised more than $21 billion globally in H1 2026, exceeding the nearly $16 billion for all of 2025.
Viabot, a Santa Clara, California autonomous robotics company, raised $24 million in Series A funding led by Walden International. It makes outdoor property maintenance robots that mow lawns, sweep parking lots, and conduct security patrols.
Combining autonomous navigation with attachments, the robots clean, remove debris, maintain landscapes, and provide soft security at large campuses and commercial properties. Viabot avoids general-purpose humanoids, applying autonomy to repetitive tasks property owners already pay people to do. Its robot-as-a-service model targets labor gaps in dirty, dull, and dangerous work.
In H1 2026, global physical AI companies—including robotics, autonomous driving, aerospace, drones, industrial automation, and sensors—raised $47.4 billion across 521 deals, nearly four times H2 2025's $12 billion.
Tellia raised $5 million in pre-seed funding led by Revent. It offers a voice-first AI platform for farmers, agronomists, and agricultural workers.
Agricultural software has long struggled because farmers do not sit at desks all day. Tellia lets workers in vineyards or almond orchards leave voice memos, send WhatsApp messages, or submit photos to log activities, generate reports, and set reminders; AI converts unstructured information into records tied to the correct field, crop, and team.
Headquartered in San Francisco and Paris, its technology is deployed on 1 million acres, with customers including Campos Brothers Farms and Duckhorn Vineyards in the U.S., and European agricultural organizations. Agtech funding remains below its 2021 peak, when agriculture and planting startups raised $10.5 billion across more than 1,400 deals, making companies that use increasingly cheap AI for specific daily farm problems a corner worth watching.
BRKZ, a Riyadh, Saudi Arabia startup, raised $31 million in new funding, including a $13 million Series B equity round co-led by Wa'ed Ventures (Saudi Aramco's venture arm) and 500 Global, plus $18 million in growth debt from Stride Ventures.
It operates a marketplace connecting construction companies and building materials suppliers while handling procurement, logistics, and financing. It has accumulated about 38 million structured data points powering an AI pricing engine trained on roughly 40,000 quote requests. The company says 84% to 89% of predicted prices fall within 5% of final transaction prices.
Another AI agent reads photos of cement delivery notes sent via WhatsApp, matches orders, and verifies deliveries, with about three-quarters of the process requiring no human intervention. Global proptech startups raised about $6.5 billion across roughly 640 deals in H1 2026.
