This monthly column covers five startup funding deals that may have gone unnoticed. This month's deals take AI and other emerging technologies well beyond the usual software stack, from nuclear reactors on barges to grading how well AI models can control robots. Other companies are bringing automation to traditional sectors such as building-material procurement, commercial property maintenance and farm recordkeeping.
Long Beach-based Bluecore Energy raised an oversubscribed $50 million seed round led by Silverton Partners, two months after emerging from stealth with $10 million in pre-seed funding. The company is developing compact, water-cooled small modular reactors that run aboard floating barges, so the systems can be manufactured and moved to where electricity is needed. Its first target is the Port of Long Beach, with other ports and AI data centers as potential customers, and it is working with the Nuclear Regulatory Commission and U.S. Coast Guard on certification. Nuclear fission startups raised roughly $2 billion in venture funding in 2025, according to Crunchbase data.
Riyadh-based BRKZ secured $31 million, made up of a $13 million Series B co-led by Wa'ed Ventures and 500 Global and an $18 million growth-debt commitment from Stride Ventures. Its marketplace connects construction companies with building-material suppliers and also handles sourcing, logistics and financing. Its AI pricing engine, trained on roughly 40,000 requests for quotes, prices 84% to 89% of requests within 5% of the final transaction price. Global proptech startups raised about $6.5 billion across roughly 640 deals in the first half of 2026.
Santa Clara-based Viabot raised a $24 million Series A led by Walden International to scale its fleet of outdoor property maintenance robots for commercial real estate. Its machines combine autonomous navigation with attachments for sweeping, debris removal and landscaping, and they also provide soft security patrols. The company runs on a robot as a service model, focusing on repetitive work that property owners already pay people to do. Global venture funding to physical AI companies reached $47.4 billion across 521 deals in the first half of 2026.
San Francisco-based Robocurve, three months old, raised a $10 million seed round led by Initialized Capital to act as an independent third-party auditor for physical AI . Its research has found that general-purpose large language models can outperform specialized robotics vision-language-action models on some simple tasks. It is incorporated as a Public Benefit Corporation with a legal duty to evaluate frontier AI systems' robotics capabilities and report the findings to the public. More than 200 institutions have joined its benchmarking program, which offers $500,000 in combined funding plus free robotic arms.
Tellia raised a $5 million pre-seed round led by Revent for a voice-first AI platform built for farmers, agronomists and agricultural workers. Users can log records, generate reports and set reminders through voice notes, WhatsApp messages or photos, which the AI turns into records linked to the correct field, crop and crew. The San Francisco- and Paris-based company says its technology is deployed across 1 million acres. Agtech venture investment is still in a correction from its 2021 peak of $10.5 billion, while voice AI has become a funding hot spot.
