Nexxa.ai, a Sunnyvale-based AI-native company, has secured $4.4 million in a pre-seed funding round to transform industrial engineering with specialized AI agents. Led by Andreessen Horowitz, the funding supports Nexxa’s mission to streamline complex operations for over 4 million engineers globally, following two quarters of 3x growth in 2025.
Nexxa.ai announced a $4.4 million pre-seed round on July 21, 2025, driven by Andreessen Horowitz, with participation from Augment Ventures, Propeller Ventures, Plug and Play, Beat Ventures, SBI, Untapped Ventures, Cross Atlantic Angels, and angel investors Rick Berry and Pat McCarthy. The funds will bolster engineering resources and expand Nexxa’s reach into new industries. The company’s selection for a16z’s Speedrun Badge 5 accelerator provides access to AI ecosystem support and go-to-market expertise. “Nexxa is shaping the future of industrial engineering with an execution-focused approach to AI,” said Troy Kirwin, partner at a16z Speedrun. “The potential of Nexxa is enormous – and they are just getting started.”
Nexxa.ai addresses the reliance of over 4 million industrial engineers on fragmented, manual processes. Its specialized AI agents integrate with existing tools like engineering and estimating systems, enabling autonomous or collaborative task execution without requiring system overhauls. “Having worked in industrials for over a decade, I believe that there has never been a more critical time to invest in technology that can have a real impact on our infrastructure. Our goal is to build an AI approach that can understand and learn deeply technical operations from scratch,” said Philipp Wehn, co-founder and CEO of Nexxa. The platform, Full Self Computing, streamlines business processes through cognitive Robotic Process Automation (RPA) on a pay-per-use model.
Founded in May 2024, Nexxa.ai has achieved 3x growth in booked annual contract value (ACV) for two consecutive quarters in 2025, with early adopters including Fortune 100 companies and midmarket firms. “Philipp brings a deep understanding of pain points for industrial businesses which existing solutions fail to address,” said Sonali Vijayavargiya, founder and managing partner at Augment Ventures. “We are backing Nexxa because they are not just automating tasks but also building intelligent systems that drive results in complex enterprise environments.” Nexxa’s integration with the Siemens Xcelerator ecosystem underscores its relevance, as noted by Mario Mattern of Siemens Mobility: “Nexxa demonstrates strong potential through its focus on AI for industrial engineering and its ability to connect with existing software systems.”
Nexxa.ai’s funding and accelerator participation position it to lead AI-driven innovation in industrial engineering. By enhancing operational workflows with scalable, context-aware AI agents, the company is set to deliver measurable impact across heavy industries, driving efficiency and modernization.
Nexxa.ai is a startup delivering specialized AI to heavy project industries. Headquartered in Sunnyvale, CA, Nexxa is shaping the emerging field of Agent Augmented Engineering. The company is backed by Andreesen Horowitz and other top-tier investors.
