Two funding rounds closed the same day at opposite edges of the AI stack. Enigma, which runs large-scale experiments exploring how humans interact with robots, emerged from stealth with a $70 million seed led by Index Ventures and Ribbit. Multiverse Computing, based in Spain and focused on shrinking large language models to reduce energy and compute costs, raised a $570 million Series C at a $1.7 billion valuation. One is betting that the interface is the unsolved problem.

Infinity.inc, an early-stage AI infrastructure research company, has closed a $15 million seed round at a $100 million post-money valuation. Touring Capital led the participation, joined by Principal Venture Partners, executives from major chip companies, researchers from OpenAI and Anthropic, and a group of angel investors. The company’s core product is Ignition, an autonomous AI agent that writes, tests, and optimizes the low-level compute kernels that determine how efficiently a chip runs AI models.

Doctronic, an AI-native healthcare platform legally authorized to practice medicine in the United States, has announced a $40 million Series B funding round co-led by Abstract and Lightspeed Venture Partners, with participation from Union Square Ventures, Seven Stars, Mantis, and Tusk Ventures. The new financing brings total funding to more than $65 million, marking the company’s third round in less than 12 months and reinforcing investor confidence in its rapidly scaling model.

Halter is pushing deeper into the idea that livestock management can become a software-defined business, and its latest funding round shows investors believe that shift is no longer experimental. The New Zealand-founded agtech company said on March 25, 2026 that it has raised $220 million in Series E funding at a $2 billion valuation, in a round led by Founders Fund with participation from Blackbird, DCVC, Bond, Bessemer, NewView, Ubiquity, Promus, and Icehouse Ventures.

Amplio, the AI startup reshaping how enterprise manufacturers manage industrial surplus, has closed an $11.1 million Series A round led by Hitachi Ventures and Yamaha Motor Ventures, with continued support from Construct Capital, Slow Ventures, Alpaca VC, and High Alpha Capital. This infusion of capital will allow the company to accelerate its go-to-market strategy, expand into new surplus categories such as rolling stock, raw materials, and finished goods, and deepen its investment in agentic AI systems tailored to complex supply chain environments.
