**Foundation** (also known as **Foundation Future Industries**, and formerly **Foundation Robotics Labs** or **Foundation Future**) is an American robotics company based in [San Francisco](/wiki/san_francisco), [California](/wiki/california), [United States](/wiki/united_states), developing [humanoid robot](/wiki/humanoid_robot)s for both industrial and military applications. Founded in April 2024 by Sankaet Pathak, Arjun Sethi, and Mike LeBlanc, the company builds the [Phantom MK1](/wiki/phantom_mk1), a 5 ft 9 in (175 cm), 176 lb (80 kg) bipedal robot that is one of the first humanoids designed explicitly for combat use.[1][2] In April 2026, Foundation disclosed roughly $24 million in research contracts across the U.S. Army, Navy, and Air Force and, in February 2026, deployed two Phantom MK-1 units to [Ukraine](/wiki/ukraine) for what it described as the first field test of a U.S.-built humanoid in an active war zone.[2][4]

The company has attracted attention for its rapid development timeline, dual-use (civilian and defense) strategy, and a series of Pentagon research awards secured within roughly two years of founding. It operates from a manufacturing site in San Francisco it calls "Robo Factory 1," with additional engineering talent drawn from Munich (including researchers from the Technical University of Munich) and IHMC in the United States. Foundation positions itself as a vertically integrated builder, designing its own actuators, software stack, and assembly process in-house.[3][8][10]

## History

Foundation was co-founded in April 2024 by Sankaet Pathak (CEO), Arjun Sethi (CEO of [Tribe Capital](/wiki/tribe_capital)), and Mike LeBlanc (co-founder of Cobalt Robotics and a 14-year veteran of the [United States Marine Corps](/wiki/united_states_marine_corps)). Pathak was previously the CEO of Synapse Financial Technologies, a banking-as-a-service fintech company that filed for bankruptcy in 2024 before he pivoted to robotics.[1][2]

The company launched with approximately $11 million in pre-seed capital led by [Tribe Capital](/wiki/tribe_capital), with participation from additional early investors. After follow-on funding in early 2025, Foundation's total disclosed funding reached approximately $21 million.[2][6]

In August 2024, Foundation acquired Boardwalk Robotics, a small robotics outfit whose proprietary cycloidal actuator technology became central to the Phantom platform. Through Boardwalk, Foundation also inherited roughly $10 million in pre-existing US government contracts, including a $1.8 million Air Force award, which helped position the startup as an approved military vendor.[2][3]

In October 2025, Foundation publicly unveiled the [Phantom MK1](/wiki/phantom_mk1), a humanoid robot designed for combat, industrial work, and other high-risk applications. The company delivered its first production humanoid roughly 13 months after founding, a pace that drew industry attention given that most humanoid programs spend longer in prototyping.[3]

In February 2026, Foundation deployed two Phantom MK-1 humanoid robots to [Ukraine](/wiki/ukraine) for battlefield trials, according to co-founder Mike LeBlanc. The units were tasked with reconnaissance and logistics rather than direct combat, but the deployment was widely reported as the first known field test of a US-built humanoid in an active war zone.[4][9]

In April 2026, Foundation was reported to have secured roughly $24 million in research and SBIR contracts spanning the US Army, Navy, and Air Force, focused on inspection, logistics, weapons handling, and breaching scenarios. The company was simultaneously reported to be raising a new round of about $500 million at a valuation exceeding $3 billion. Eric Trump joined the company as Chief Strategy Adviser, a hire that drew political scrutiny from Senator Elizabeth Warren and others.[2][5][6][11]

## What is the Phantom MK1?

### Phantom MK1

The [Phantom MK1](/wiki/phantom_mk1) is Foundation's flagship humanoid robot. It is a bipedal, full-size humanoid designed to operate in both factory and field environments, with technical choices oriented toward ruggedness, simplicity, and military adaptability.

#### How do the Phantom's actuators work?

Foundation developed proprietary cycloidal actuators, originally acquired through the Boardwalk Robotics purchase, that deliver high torque (up to 160 Nm) while remaining back-drivable below 1 Newton-meter. The company claims energy efficiency of around 90 to 95 percent, compared to roughly 50 to 60 percent for traditional harmonic drives. The rolling-element design is intended to absorb shock loads, reduce wear, and provide the compliance needed for safe human-robot interaction.[3][8][10]

The Phantom's actuators are assembled by hand inside the San Francisco factory. Foundation also incorporates titanium rods in the shins to handle the high-vibration loads of bipedal walking.[3]

#### Why does the Phantom use cameras instead of LiDAR?

The Phantom MK1 uses a camera-only perception stack, with reports describing between six and eight cameras providing near-360-degree coverage. Foundation has chosen to skip [LiDAR](/wiki/lidar) to simplify the platform, reduce cost, and improve compatibility with neural-network perception pipelines. Reporting from Humanoids Daily notes the cameras are used for both task execution and general safety awareness.[3][8]

The perception system is paired with a large language model layer that translates spoken commands such as "pick that up" into whole-body motions. Foundation describes its approach as hybrid AI: imitation learning for fine manipulation, state-based models that incorporate physics and task dynamics, and reinforcement learning for locomotion. Pathak has said that simple manipulation tasks can be trained in around 30 minutes of demonstration.[8]

#### Hands

The production Phantom MK1 ships with five-fingered, anthropomorphic hands. A next-generation hand prototype, internally called "Mach 2," uses a tendon-driven design with around 24 motors and bio-inspired DIP, PIP, and MCP joints. The Mach 2 hand allows finger abduction and adduction as well as flexion and extension, aiming to bring dexterity closer to that of a human hand.[3]

#### Defense features

For military applications, the Phantom MK1 has been reported to include ballistic armor and a stealth coating designed to lower its thermal signature. The robot can carry up to 20 kg of equipment, which may include weapons, supplies, or sensors. Foundation has emphasized that armed configurations are envisioned as human-in-the-loop, similar to current military drone operations, with human operators retaining authority over lethal decisions.[1][6]

### Phantom 2

Foundation has said it intends to follow the Phantom MK1 with a successor, the Phantom 2, which Pathak has described as offering "superhuman abilities" and roughly double the payload capacity of the first generation. The company has stated it aims to send improved robots to Ukraine during 2026, addressing shortcomings identified in early field testing such as limited waterproofing and battery life.[5][12]

## How is the Phantom MK1 manufactured?

Foundation manufactures the Phantom MK1 at its San Francisco site, branded as Robo Factory 1. The factory features a largely manual assembly line, where workers hand-build actuators and integrate the roughly 500 unique parts that make up each robot. Approximately 30 percent of components are sourced from China, with the remainder drawn from suppliers in the United States, Mexico, Israel, and South Korea.[3]

Reporting on the company's leadership notes that its head of manufacturing previously led the Tesla Model X and Model Y production ramps, and that engineers have been recruited from Tesla, Boston Dynamics, SpaceX, and 1X. The factory is treated as both a production line and a learning environment, with the company iterating on actuator designs and hand prototypes alongside ongoing builds.[5][3]

## Production roadmap

Foundation has announced an aggressive ramp schedule for Phantom MK1 deployments. CEO Sankaet Pathak has described the timeline as ambitious, telling reporters there is a "non-zero chance" the company can hit its targets.[5]

| Year | Target units | Cumulative |
|------|--------------|------------|
| 2025 | 40 | 40 |
| 2026 | 10,000 | ~10,040 |
| 2027 | 50,000 | ~60,040 |
| Steady state | 30,000 per year | n/a |

These targets imply roughly a 250-fold scale-up on the company's roughly $21 million in disclosed funding, which has prompted skepticism from analysts who note that established defense manufacturers such as ARX Robotics currently produce around 1,800 autonomous units per year.[2]

## What is the Phantom MK1 used for?

### Industrial

Foundation positions the Phantom MK1 for tasks where a general-purpose bipedal worker can substitute for human labor, including:

- Logistics and material handling
- Aircraft maintenance and inspection
- Manufacturing assembly
- Space construction (an aspirational use case the company has cited but not yet demonstrated)

The leasing model, priced at roughly $100,000 per year per robot, is intended to compete with multi-shift human labor costs in industrial settings.[5][8]

### Defense

Foundation's defense work is anchored by contracts originally acquired through Boardwalk Robotics, supplemented by newer Pentagon research awards across the Army, Navy, and Air Force. The company holds an SBIR Phase 3 designation, which qualifies it as an approved military vendor. Reported defense applications include:[2][3]

- Reconnaissance and surveillance
- Bomb disposal and breaching
- Casualty evacuation
- Logistics and resupply in contested areas
- Patrol roles, with Pathak publicly suggesting US border deployment as a possible future use case

Foundation has been open about wanting to arm the Phantom platform under appropriate rules of engagement, a posture that distinguishes it from most other US humanoid startups, which generally avoid weaponization. The company has said it wants Phantom robots on U.S. front lines within roughly 18 months.[11]

#### What happened when the Phantom MK-1 was tested in Ukraine?

The two Phantom MK-1 units sent to Ukraine in February 2026 were used to demonstrate logistics tasks such as supply pickups that would otherwise expose soldiers to danger. Pathak has said the trials proved the core technology's potential, but Ukrainian assessments and reporting described the first-generation units as far from battle-ready: they carried only about a 44 lb (20 kg) payload and lacked the waterproofing and battery life needed for sustained frontline use. Foundation framed the deployment as a learning exercise informing the Phantom 2 design rather than a combat capability.[4][9][12]

## Controversy

Foundation has drawn scrutiny on several fronts. In June 2024, CNBC reported that the company had used exaggerated claims about a relationship with [General Motors](/wiki/general_motors) in early fundraising materials, including references to a roughly $300 million purchase order and a claimed investment commitment that General Motors denied. Co-founder Mike LeBlanc later said he was "embarrassed" the marketing material existed.[7]

Pathak's previous company, Synapse Financial Technologies, collapsed in 2024 amid disputed fund balances and a contentious bankruptcy, with tens of millions in consumer deposits reported unaccounted for, leading some investors and observers to approach Foundation with caution.[1][2]

The company's open embrace of military applications has generated debate within the robotics community, where companies such as Boston Dynamics, Agility Robotics, and Figure have publicly distanced themselves from weaponization. Foundation's deployment of robots to Ukraine in early 2026 intensified the discussion, as did the appointment of Eric Trump as Chief Strategy Adviser. Reacting to the $24 million in Pentagon awards going to a politically connected vendor, Senator Elizabeth Warren said, "Is the Pentagon just a cash machine for Trump's kids now?" and characterized the arrangement as "corruption in plain sight."[2][11]

## Who leads Foundation?

| Name | Role | Background |
|------|------|------------|
| Sankaet Pathak | Co-founder and CEO | Former CEO of Synapse Financial Technologies |
| Arjun Sethi | Co-founder | CEO of [Tribe Capital](/wiki/tribe_capital) |
| Mike LeBlanc | Co-founder | Co-founder of Cobalt Robotics, 14-year US Marine Corps veteran |
| Eric Trump | Chief Strategy Adviser (from 2026) | Businessman and son of Donald Trump |

## How does Foundation compare with other humanoid startups?

Foundation is one of a growing group of US humanoid robotics startups, most of which focus on industrial and commercial deployments rather than defense. The table below summarizes how Foundation's positioning compares with several peers.

| Company | Headquarters | Flagship robot | Primary market |
|---------|-------------|----------------|----------------|
| Foundation | San Francisco, CA | [Phantom MK1](/wiki/phantom_mk1) | Industrial and defense |
| Figure AI | Sunnyvale, CA | Figure 02 | Industrial, logistics |
| Agility Robotics | Salem, OR | Digit | Logistics, warehousing |
| 1X Technologies | Norway and California | Neo | Consumer and commercial |
| Apptronik | Austin, TX | Apollo | Industrial, logistics |
| Tesla | Palo Alto, CA | Optimus | Industrial, consumer |
| Boston Dynamics | Waltham, MA | Atlas (electric) | Industrial |

What most sets Foundation apart from this peer group is its explicit defense focus and willingness to weaponize, combined with a production roadmap (tens of thousands of units per year) that is far more aggressive than its disclosed funding would typically support.[2][5]
