Walden Robotics and TerraFirma raise $300 million and $100 million, respectively, as investors fund robotics, automation, and infrastructure adjacent to core AI platforms.

Largest financings span AI, delivery and robotics

As reported by Crunchbase News, the week’s biggest private funding rounds show continued investor appetite for artificial intelligence and adjacent technologies rather than a seasonal slowdown. The largest deal goes to San Mateo, California-based Fireworks AI, which raises $1.505 billion in Series D funding led by Atreides Management, Index Ventures and TCV, giving the enterprise AI tools company a $17.5 billion valuation.

Wonder follows with a $650 million Series D at a $9 billion pre-money valuation, with the New York-based meals and delivery company saying the capital will support expansion of its operations, which currently span 140 locations. In life sciences AI, Chai Discovery secures $400 million in Series C funding at a $3.8 billion valuation, led by Index Ventures with backing from Sequoia Capital, Dimension, Kleiner Perkins and others.

Robotics and industrial technology also feature prominently. Walden Robotics launches from stealth with $300 million in funding led by Toyota and Deviation Capital, valuing the Cambridge, Massachusetts-based robotics startup at $1.1 billion, while Austin-based TerraFirma lands $100 million in fresh funding for construction automation technology.

Investor focus broadens across sector applications

Beyond the largest AI rounds, investors also back companies applying technology to public safety, enterprise infrastructure, defense and financial services. Seattle-based drone developer Brinc raises $125 million in financing led by Motorola Solutions, with participation from Index Ventures and Figma founder and CEO Dylan Field.

Spectro Cloud says it raises more than $100 million in a Series D led by Goldman Sachs Alternatives, lifting total capital raised by the San Jose-based AI infrastructure management software provider to $260 million. Defense technology startup Singularity emerges from stealth with $80 million in Series A funding led by Khosla Ventures and Felicis, at a $400 million valuation.

The week’s remaining top rounds include a $70 million Series B1 for San Francisco-based fintech startup Flex, led by Halo Fund, and a $70 million Series A for State Affairs, an AI platform focused on policy and regulation, led by Khosla Ventures and Founders Fund. The mix of financings suggests venture investors continue to target both core AI platforms and industry-specific applications with large capital needs.

In our earlier article on Dell’s AI-optimized server momentum, we noted that renewed demand and the company’s ongoing Nvidia partnership helped support the stock despite headwinds. The piece also highlighted market concerns about potential AI infrastructure overcapacity, insider selling, and key technical levels that could cap near-term upside.
