About Persona AI

Persona AI, Inc. was founded in June 2024 by three robotics veterans who between them have spent decades building humanoid and rugged autonomous systems for some of the hardest environments on Earth. Nicolaus “Nic” Radford, the CEO, spent roughly 15 years at NASA's Johnson Space Center, where he was chief engineer of Robonaut 2 — the first humanoid robot on the International Space Station — and later led the team that built Valkyrie, NASA's first full-size bipedal humanoid. He then founded Houston Mechatronics (now Nauticus Robotics), which built the transforming underwater vehicle Aquanaut. His co-founders are Jerry Pratt, previously Chief Scientist at Figure AI and long-time lead of the Nadia humanoid program at the Florida Institute for Human and Machine Cognition (IHMC), and Jide Akinyode, formerly VP of Engineering at Nauticus and part of the NASA Valkyrie program, who serves as COO.

Rather than compete with Figure, Apptronik, Tesla Optimus, and 1X in general-purpose manufacturing and warehouse humanoids, Persona has chosen a deliberately narrower and more industrial wedge. Radford has publicly described the target as the “4D jobs” — dull, dirty, dangerous, and declining — with a near-term focus on shipyard welding, pipe welding, fabrication, and oil-and-gas maintenance. The bet is that the labor shortages, safety pressures, and physical demands in these sectors are severe enough that a full-size, ruggedized, purpose-built humanoid can command commercial pricing well before consumer-grade general-purpose robots are ready. Persona plans to operate its fleet primarily on a robotics-as-a-service (RaaS) model, retaining ownership of the machines and selling their labor output.

The company launched publicly in what Radford called “anti-stealth mode” and moved quickly. In February 2025 it disclosed an initial pre-seed of roughly $10 million; in May 2025 it announced an oversubscribed pre-seed close totaling $27 million, co-led by Unity Growth and Tides Ventures, with participation from Mirae Asset Group, Goose Capital, K2 Global, K50 Ventures, Tola Capital, Embedded Ventures, and more than a dozen additional funds. The company has publicly described additional seed-stage financing that brings cumulative disclosed funding to approximately $42 million. Its main operations are in Houston at the Ion innovation hub on Main Street, with an additional engineering team in Pensacola, Florida centered around Pratt.

Persona's most consequential commercial validation to date is its partnership with HD Hyundai. In May 2025 the company signed a Memorandum of Understanding with HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and HD Hyundai Robotics to jointly develop welding humanoids for shipyard automation, and in March 2026 the four parties (adding Korean industrial integrator Vazil Company) signed a formal joint development agreement to commercialize the platform. HD Hyundai publicly stated that Persona's prototype had demonstrated “sufficient technological feasibility and real-world potential,” with prototype completion targeted for the end of 2026 and phased shipyard deployment beginning in 2027.

Technology stack

Persona AI's platform is a vertically integrated combination of custom industrial mechatronics, multi-modal perception, and an in-house AI stack for whole-body control and task learning. The company's technical thesis — publicly articulated by Radford and Pratt — is that a humanoid for heavy industry must be built “rugged first” and that the AI layer must be trained on real, messy industrial work rather than polished lab demonstrations.

Perception

Persona has stated that PA-1 uses a multi-camera vision system, depth sensing, and touch/force feedback at the manipulators, tuned for the challenges of a shipyard or refinery: variable lighting, occluded workpieces, weld arcs, dust, and confined spaces. Under the HD Hyundai joint development agreement, HD KSOE and HD Hyundai Robotics contribute welding-path AI training data and system-integration validation from real shipyard operations, giving Persona an industrial-scale dataset that pure commercial humanoid startups typically lack.

AI, control, and learning

Persona is building its own AI stack for embodied control, drawing on Pratt's prior work on the Nadia humanoid at IHMC and on Figure AI's early control and learning efforts. The company has not published a model card in the style of Figure's Helix, but public materials describe an approach centered on learned whole-body control, skill-specific fine-tuning for welding and fabrication, and human demonstration and teleoperation as data-collection modes for training. Industry trackers have noted planned integration with the NVIDIA Isaac GR00T foundation-model framework as one path to scale skill learning.

Actuators, power, and compute

PA-1 uses electric brushless DC (BLDC) actuators throughout the body — no hydraulics — which is consistent with the broader industry move to all-electric humanoids. Public and third-party specifications describe a full-size platform in the 1.7–1.8 m range weighing roughly 80 kg, with a reported total lift capacity near 30 kg and roughly 12 kg per arm continuous. Runtime targets sit near five hours per battery cycle, using dock-based industrial charging. Onboard compute is high-performance GPU-class acceleration sized to run learned control policies on the robot.

Power management is a particularly demanding subsystem for an industrial humanoid. Each joint's servo controller must deliver hundreds of watts of instantaneous torque without thermally throttling, which drives the use of high-efficiency wide-bandgap semiconductors (SiC and GaN) in the motor-driver stages and requires tightly matched precision passives on every gate-drive and current-sense channel. The onboard battery pack integrates cell balancing, thermal management, and multi-stage protection ICs — subsystems whose reliability is often the practical ceiling on how long a humanoid platform can run between charges in a hot, dirty, high-vibration environment like a shipyard.

The robotics supply chain — where Hybrid Electronics fits in

A modern humanoid robot is one of the most component-dense products ever built. A single Persona-class industrial humanoid depends on thousands of individual electronic components: precision BLDC motor drivers, high-torque servo modules, IMUs and 6-DoF force-torque sensors, LiDAR and time-of-flight modules, GPU compute boards, battery-management ICs, wide-bandgap SiC/GaN power semiconductors, high-speed board-to-board connectors, precision resistors, and thousands of MLCC capacitors distributed across every power and signal rail. An industrial humanoid built for shipyard and refinery duty adds another layer of demand: ruggedized connectors, isolation ICs, and industrial-temperature-grade passives that survive vibration, heat, and moisture over long duty cycles.

Building that kind of hardware puts enormous pressure on the electronic-components supply chain. Prototype pilots and low-volume production runs frequently hit allocation, EOL notices, and long lead times on the exact parts they need, and R&D and field-service teams routinely have to support older platforms that use semiconductors no longer in mainstream distribution. During the current humanoid robotics and general-purpose robot AI boom, this pressure is amplified: dozens of well-funded teams — Figure, Apptronik, Sanctuary AI, 1X, Tesla, Agility, and Persona among them — are chasing the same short list of high-torque BLDC drivers, precision IMUs, GPU compute modules, and automotive- and industrial-grade power semiconductors, and franchise stock on many key parts is now measured in months of lead time rather than weeks.

Hybrid Electronics has been sourcing electronic components for industrial and embedded systems since 1995. For robotics teams — humanoid, mobile, industrial, and research — we specialize in finding the parts you need when mainstream distribution can't:
