Agtonomy is a South San Francisco–based software and services company that brings autonomous operation to agriculture, turf, and broader land-maintenance markets. Its physical AI platform is integrated directly into commercial equipment through partnerships with leading original-equipment manufacturers (OEMs), enabling machines to navigate and work autonomously in orchards, vineyards, fields, and managed green spaces. The technology is designed to reduce labor costs, boost safety, and promote more sustainable farming and land-care practices. Agtonomy generates revenue by licensing its software and providing related automation services to OEM partners and end-customers. To date, the company has secured $18 million in Series B funding and counts investors such as DBL Partners, Nuveen, Autotech, Allison Transmission, Rethink Food, and Black Forest Ventures on its cap table. The new capital will be used to enhance the platform’s capabilities, broaden equipment integrations, and scale commercial deployments into adjacent off-road industries.

Founded in 2022 with backing from energy-focused asset manager Kimmeridge, Chestnut Carbon designs and operates U.S. afforestation projects that convert marginal cropland and pasture into biodiverse forests. The company produces Gold Standard-verified carbon removal credits that help corporations meet decarbonization and net-zero targets. Chestnut has already purchased more than 60,000 acres across eight southern states for these projects. Its growth strategy includes continued land acquisitions and investment in proprietary data tools and patented systems to refine forest modeling and operational efficiency. Recent financing has positioned Chestnut among the best-funded players in the 2025 voluntary carbon market, with $250 million raised year-to-date. Management emphasizes rigorous quality and permanence standards to serve customers seeking trustworthy offsets.

Founded in 2019, Rain develops an autonomous wildfire containment platform that pairs pre-positioned aircraft with a wildfire intelligence system to perceive, understand and extinguish nascent ignitions within minutes. The solution integrates with existing detection networks, automatically dispatching Rain-equipped aircraft seconds after a fire is spotted, thereby shortening response times by up to 15 minutes—a gap researchers estimate could save billions of dollars annually in California alone. Headquartered in Alameda, California, the company works closely with fire professionals to modernize aerial firefighting and keep pilots out of harm’s way. Rain’s technology addresses a market where U.S. wildfire-related costs average $348 billion per year and extreme events are projected to rise 14 % by 2030. Policy guidance from both the White House and Congress in 2023 is encouraging agencies to adopt autonomous aircraft, adding further momentum to Rain’s offering. The company’s recent $9.7 million seed financing will fund pilot projects across the United States and accelerate product deployment.

R-Zero develops connected biosafety technology that pairs UV-C products (Arc, Beam, Vive) with IoT sensors and AI-driven software to neutralize airborne and surface microorganisms and produce actionable space-use and disinfection insights. Its platform captures occupancy and disinfection data to optimize how indoor spaces are used and to enable risk modeling and mitigation. The company sells hardware and sensors that automate and provide visibility into disinfection across education, healthcare, corporate, and public sector environments. R-Zero intends to scale deployments of its disinfection and risk-modeling technology to meet demand across K-12 schools, college campuses, corporate campuses, hospitals, senior care communities, parks and recreation, and other government facilities. Led by CEO Jennifer Nuckles, the company emphasizes making shared indoor spaces safer, more efficient, sustainable, and productive. Financially, R-Zero has raised significant institutional capital to date to support expansion, including a recent large financing that increased its total capital raised to more than $170M. R-Zero develops an intelligent biosafety platform combining AI, machine learning, IoT-connected hardware, and data science to enable continuous, automated disinfection of indoor spaces. Its first product, Arc, is an IoT-enabled whole-room UV disinfection device currently deployed to protect hundreds of thousands of people across public and private organizations. The company is positioning a broader ecosystem to measure, manage, and reduce infectious-disease risk in hospitals, schools, workplaces, and other shared environments. R-Zero emphasizes evidence-based approaches and plans clinical studies and integrated data-management solutions as part of its product roadmap. The platform aims to deliver greater visibility, automation, and smarter risk reduction without chemical disinfectants. R-Zero is backed by venture firms DBL Partners, World Innovation Lab, and SOSV/HAX, as well as Mayo Clinic and industry thought leaders in hospitality, sports, and commercial real estate. R-Zero designs and sells an IoT-enabled whole-room UV-C disinfection product called Arc and is building the world’s first continuous, automated disinfection ecosystem. The platform combines IoT hardware with data science, AI and ML to provide visibility, automation and risk reduction for indoor spaces. R-Zero says Arc currently protects thousands of schools, senior care facilities, offices, sports and event venues, correctional facilities, clinics, restaurants, gyms and more, and enables a higher level of health safety for hundreds of thousands of people. The company reports its UV-C technology reduces disinfection carbon footprint by 93%, generates over 250x less waste and reduces risk by more than 15x versus traditional chemical disinfection. R-Zero plans to accelerate product innovation and broader deployment to establish a new standard for post-pandemic indoor health security. Growth has accelerated as organizations prioritize safer indoor environments and data-driven approaches to disinfection. R‑Zero develops hospital‑grade biosafety technologies, with a flagship product called Arc — a touchless, IoT‑enabled UV‑C disinfection device offered via a hardware‑as‑a‑service subscription. Arc includes BLE, LTE‑M and GPS connectivity to provide real‑time usage data and an auditable trail of disinfection activities. Independent lab tests show Arc destroys over 99.99% of pathogens (including human coronavirus, E. coli, MRSA and feline calicivirus) in a 1,000 sq ft space in under seven minutes. The company has seen rapid early traction across schools, more than one million square feet of office space, athletic facilities, restaurants, hotels and senior care. R‑Zero says the new capital will accelerate production and deployment of Arc and fund continued development of additional product innovations to establish a new standard for public health and safety. The company positions its lower‑cost, hospital‑grade offering as a democratizing alternative to incumbent hospital UV systems that are far more expensive and cumbersome to deploy.
