Nexxa.ai has raised a $9 million seed round to scale specialized AI agents designed for heavy-industry workflows, as the company looks to expand deployments across rail, construction, manufacturing, and other critical infrastructure sectors.
The Sunnyvale, California-based startup, founded in 2024, said the round was led by Construct Capital, with significant participation from a16z speedrun and existing investors. The seed financing brings Nexxa.ai’s total funding to $14 million, including a prior $4.4 million pre-seed round led by a16z speedrun with participation from Augment Ventures, Propeller Ventures, Plug and Play, Beat Ventures, SBI, Untapped Ventures, Cross Atlantic Angels, and angel backers including Rick Berry and Pat McCarthy.
Nexxa.ai is positioning its platform as a layer that sits on top of the tools industrial engineers and operators already use, aiming to modernize work that is often handled through fragmented software stacks and manual processes. Rather than replacing legacy systems, the company says its approach integrates into existing workflows to help teams plan, execute, and manage complex engineering and operational tasks.
At the center of the product is Nitro, a multi-agent orchestration platform that coordinates specialized AI agents through what Nexxa describes as a rule-based management console. The company says the design is intended to keep AI-driven work compliant, explainable, and aligned with operational standards, while enabling deployments in a matter of weeks without disrupting mission-critical systems. Nexxa also emphasizes a forward-deployed engineering model, in which teams work closely with customers to tailor and implement solutions directly inside real operational environments.
Nexxa.ai said its software is already being used by enterprises including Siemens and Matikon, along with additional customers that remain undisclosed. The platform is also available through the Siemens Xcelerator Marketplace, which could help broaden distribution inside large industrial organizations that already standardize on Siemens ecosystems.
The funding will be used to expand customer deployments, deepen product capabilities, and scale into additional heavy-industry workflows. Nexxa.ai also said it is preparing to target significant revenue growth in 2026, arguing that industry-specific AI is reaching an inflection point as companies face rising costs, shifting labor dynamics, and increased infrastructure and energy demands.
KEY QUOTES:
“Everyone talks about AI disrupting white-collar work. The real opportunity is strengthening the backbone of the economy. America is in a race to rebuild heavy industry, so we’re making AI native to industrial engineering and operations, bringing it directly into the existing tools and workflows industrial companies use every day, so they can lead and grow their company in a way they never could before.”
Philipp Wehn, Co-Founder and CEO, Nexxa.ai
“Nexxa is tackling a vital problem: how do you modernize the core industrial base without ripping out everything that already works? The team has shown that when you deliver AI that plugs into real workflows and drives measurable ROI in weeks, even traditional industries are ready to move fast.”
Camila Key Saruhashi, Early Stage Venture, Construct Capital
“Nexxa.ai is taking specialized AI out of the lab and putting it to work in heavy industry. They are delivering measurable ROI in rail, construction, and manufacturing sectors where complexity has historically slowed adoption. That ability to translate AI into real operating leverage gives us conviction that Nexxa can build a category-defining company.”
Sonali Vijayavargiya, Managing Partner, Augment Ventures
“What impressed us is how quickly Nexxa turned AI into hard business outcomes for rail, construction, and manufacturing customers. This new capital will help them scale into the core sectors that define America’s competitiveness across customers and workflows.”
Andrew Chen, General Partner, a16z speedrun
