Inside the cavernous double-hulls of a commercial ship under construction, welding is among the most punishing jobs in heavy industry. That is the workplace Persona AI, a Houston-based humanoid robotics startup founded in 2024, has chosen as its first deployment environment. The company has signed a partnership with HD Korea Shipbuilding & Offshore Engineering (KSOE) and HD Hyundai Robotics to develop and deploy AI-powered humanoid welding robots for shipyards [The Robot Report].
Persona AI is building bipedal humanoid robots aimed squarely at heavy industry. The company describes its near-term targets as hull welding and repair work in shipbuilding, plus pipe welding, inspection, and maintenance in the energy sector [Persona AI]. Shipyards and energy facilities pay well for skilled welders, face acute labor shortages, and operate in environments where the safety case for sending a machine in first is straightforward.
Independent forecasts project the humanoid robot market to reach approximately USD 29.57 billion by 2032 at a 39.2 percent CAGR [industry market report]. A humanoid form factor matters here because shipyards and refineries were designed around human bodies climbing through human-sized openings. Retrofitting facilities for fixed automation is often impractical; sending in a bipedal robot that can use existing ladders, scaffolds, and tool interfaces is the more tractable path.
The company raised approximately $27 million in an oversubscribed pre-seed round announced in May 2025, with Capital Factory among the backers and Unity Growth Fund LLC also participating [The Robot Report]. Earlier reporting referenced a $10 million figure, which appears to have been a partial disclosure ahead of the final close [InnovationMap].
| Metric | Value |
|---|---|
| Pre-seed round (May 2025) | $27M |
| Earlier disclosed tranche | $10M |
Co-founder and CEO Nic Radford previously led humanoid and robotics work at NASA, founded Nauticus Robotics, and worked at Jacobi Motors [IEEE Spectrum]. Co-founder and CTO Jerry Pratt spent decades at the Florida Institute for Human and Machine Cognition [IEEE Spectrum]. The early hires reinforce the bench: Michael Patrick Perry, formerly of Boston Dynamics and DJI, has joined as Head of Commercial Strategy, Matt Carney is Chief Engineer, and Jide Akinyode serves as Chief Operating Officer [Persona AI].
Humanoid robotics is among the most capital-intensive categories in deeptech. Bears will argue that a $27 million pre-seed is a thin runway for a humanoid program. The bull answer is the focus: by targeting shipyard welding rather than general-purpose manipulation, Persona can constrain the perception, planning, and end-effector problems to a domain where success criteria are measurable.
There is no peer-reviewed performance data on Persona's robots yet. What to watch over the next twelve months: a first hardware reveal, any expansion of the HD KSOE relationship into a commercial purchase order, and a likely seed or Series A round. The standard of care today for confined-space industrial welding is a human welder in protective gear. Any system that can credibly take on even a fraction of the confined-space hours, with comparable weld quality and an acceptable safety record, would find willing buyers.
