Persona AI

Who they are

Persona AI is a Houston-based startup building rugged humanoid robots for one unglamorous, well-chosen job: welding in shipyards. Its founding team is unusually credentialed for a company this young. Chief executive Nic Radford spent some 15 years at NASA, where he was a principal investigator at the Dexterous Robotics Lab, and founded the underwater robotics firm Nauticus Robotics; chief technology officer Jerry Pratt was previously CTO at Figure AI; chief operating officer Jide Akinyode led engineering at Nauticus.

In May 2025 the company closed a $27m oversubscribed pre-seed round led by Unity Growth and Tides Ventures, with backers including Mirae Asset Group. It plans to sell robot labour as a service rather than machines outright, sparing shipyards the capital outlay.

The technology

The product is a bipedal humanoid engineered for high-precision welding in the confined, cluttered, part-built structures of a working shipyard — an environment that defeats gantry automation and most wheeled platforms. The programme is anchored by HD Hyundai, the world's largest shipbuilder. A memorandum of understanding signed on 7 May 2025 brought together HD Korea Shipbuilding & Offshore Engineering (HD KSOE), HD Hyundai Robotics, Persona AI and the welding-equipment firm Vazil; on 23 March 2026, at HD Hyundai's R&D centre in Pangyo, the parties signed a joint development agreement opening a verification phase, after a prototype developed over the preceding year demonstrated technical viability.

The division of labour is explicit: Persona AI builds the humanoid platform and its AI, HD KSOE contributes training models built on shipyard operational data, HD Hyundai Robotics handles system integration and quality control, and the classification society ABS is collaborating on broader applications. The stated timeline is a completed prototype by the end of 2026, with field testing and commercial deployment from 2027. It should be said plainly: no robot is welding ships commercially today. What exists is a prototype, a staged industrial programme with dates attached, and partners with every incentive to hold it to them.

Why it matters for UK & Ireland

The UK connection is prospective, there is no Persona AI engagement with any UK or Irish yard on record, but the demand-side case writes itself. British naval shipbuilding is concentrated at Govan on the Clyde, Barrow-in-Furness and Rosyth, and its binding constraint is increasingly people who can weld. WorldSkills UK estimates the national shortage of skilled welders at more than 35,000, against just 231 trainee welders graduating from UK colleges in 2024.

The shortage has already forced improvisation at the naval yards themselves: Babcock has recruited roughly 300 overseas welders for the Type 31 frigate programme at Rosyth, citing the specialist nature and scarcity of the skills required. A robot welder proven on Korean commercial hulls would land in Britain not as a novelty but as an answer to a documented, quantified gap. That is the mapping; it is need-side only, and nothing more.

What to watch

The signals are unusually datable. First, does the prototype complete by the end of 2026, and do 2027 field tests begin in an HD Hyundai yard on schedule? Slippage in Korea pushes everything else out. Second, weld quality: the involvement of ABS matters, because class-society acceptance of robot-laid welds is the gate between demonstration and production use, in naval work above all.

Third, the UK link itself: any approach to or from BAE Systems or Babcock, or inclusion of robotic welding in UK shipbuilding skills planning, would be the first hard evidence that the mapping is becoming a relationship. Until then this remains a company being watched for a UK connection rather than one with evidenced UK relevance — the thesis would be confirmed by a Korean production deployment followed by British interest, and undermined if the verification phase ends quietly or the welding proves to need more human finishing than the economics can bear.
