Philipp Wehn spent over a decade watching engineers at Siemens and Kearney wrestle with fragmented software. In 2024, he and co-founder David Huang started Nexxa.ai to build specialized AI agents that work by watching the screen, not by ripping out the stack. Nexxa.ai has raised $13.4 million to prove it. A $4.4 million pre-seed round led by Andreessen Horowitz in July 2025 was followed by a $9 million seed round led by Construct Capital in January 2026 [PRNewswire, July 2025][Yahoo Finance, Jan 2026].
The computer-use wedge
Nexxa.ai’s product is a multi-agent system designed to sit on top of existing industrial software. The agents operate via what the company calls “computer-use AI,” interacting with the same screens and interfaces as a human engineer [Nexxa.AI]. The goal is to automate complex, end-to-end workflows without requiring deep API integrations or system replacement [Nexxa.AI]. The company claims no pre-training on customer data is required to start [Nexxa.AI].
Founders with field and code credentials
The founding team pairs domain depth with technical pedigree. CEO Philipp Wehn brings over ten years of experience in rail, metals, automotive, and construction from his time at Siemens and consultancy Kearney [a16z Speedrun, retrieved 2026]. CTO David Huang was previously a security engineer at Facebook [TechCrunch, 2018]. The team now numbers between 11 and 50 employees [LinkedIn].
Early traction and the metrics question
Nexxa.ai points to strong early signals. Company materials presented in the a16z Speedrun accelerator claim the startup went from “0 to 980K in 9 months” and has sustained a growth rate of “3x every quarter” [a16z Speedrun, retrieved 2026]. They also report a “100% activation rate on all projects” [a16z Speedrun, retrieved 2026].
Where the wheels could come off
The market Nexxa.ai is chasing is famous for long sales cycles and entrenched procurement processes. The company’s differentiation rests on a few key assertions that will be tested in the next twelve months, including the reliability of its "computer-use" layer and its ability to convert pilot projects into enterprise-wide deployments.
The next twelve months
Nexxa.ai is hiring for customer-facing roles, including a Customer Solutions Architect and an Account Executive & Business Development Lead. The focus will be on converting pilot projects into expanded deployments within its current verticals.
