PrivateOne brain, any robot, any task — the first unified robotics foundation model
Skild AI builds general-purpose robotics foundation models that can operate any robot for any task. Founded by two CMU Robotics Institute professors, backed by $2B+ from SoftBank, Nvidia, Bezos, and Sequoia at a $14B valuation.

The verdict
The leading robot-foundation-model pure-play by capital and strategic syndicate, but its $14B mark prices a software-layer monopoly that the Foxconn/Blackwell line has yet to prove and that Physical Intelligence + NVIDIA's own GR00T are both armed to contest.
What it is. Skild AI is a Pittsburgh-based robotics-AI lab building "the Skild Brain" — a single, robot-agnostic ("omni-bodied") foundation model that controls any robot body (quadruped, humanoid, tabletop arm, mobile manipulator) without prior knowledge of its exact morphology, and without per-robot retraining. Founded May 2023 by two former Carnegie Mellon Robotics Institute professors, Deepak Pathak (CEO) and Abhinav Gupta (President).
The deliberate strategic choice — no hardware. Unlike Figure, 1X, or Tesla Optimus, Skild builds no proprietary robot. It sells the intelligence layer to run on hardware made by anyone. This is the central bet: that in robotics, as in LLMs, value migrates from the body to the brain. The robotics commercial layer frames this exactly — Skild sits in the "Software-stack players" row ("General-purpose robot brain") next to Physical Intelligence, NVIDIA GR00T, and Covariant, distinct from the builder/integrator row (Tesla, Figure, Agility, Unitree).
Business model. B2B software — foundation-model licensing via cloud APIs, plus fine-tuning/post-training services and vertical software modules. As of late 2024 monetization was still "in development" with no reported customers; by the Series C the company reported "live revenue grew from zero to about $30M in just a few months in 2025… with multiple customers". The model is pre-trained on simulation + internet human-action video, then post-trained on targeted real-world robot data to deliver working customer solutions.
Customers / deployment sectors (named). Security, construction, delivery, data centers, warehouses, factory assembly. The marquee deployment: with Foxconn, the Skild Brain is being put on robotic assembly lines that build NVIDIA's Blackwell GPU server systems in Houston, Texas. NVIDIA is also brokering integrations with ABB Robotics and Universal Robots. A June 2026 MOU with VinDynamics (a Vingroup robotics arm) targets humanoid integration of the Skild Brain.
Key payment-term / contract structure. Not publicly disclosed — n/a — private, not disclosed. The implied shape is per-robot/per-deployment software licensing + post-training services; no take-or-pay or backlog figures are public.
One-line: A CMU-pedigree, no-hardware "robot brain" lab betting the entire robotics margin pool migrates from the body to the model — and that one model can rule every body.
Skild is a software/model layer, so its "supply chain" is (a) the inputs to train the brain and (b) the hardware bodies + channel it must ride to reach an end customer. Mapping it against the robotics chain:
Upstream inputs (what feeds the Skild Brain):
Midstream (Skild) → downstream (bodies + buyers):
Chokepoints / single-source dependencies:
Names or it didn't happen: HPE (compute), NVIDIA Jetson/Thor (inference) + NVentures (capital) + GR00T (rival), Foxconn (line + buyer), ABB + Universal Robots (body channels), VinDynamics/Vingroup (humanoid MOU), AWS-class cloud (training).
The bull's moat stack:
Bargaining power — who needs whom?
Verdict on the moat: Real on capital + syndicate + research talent; aspirational on the data/omni-body claim that is the whole thesis. The durable-moat question reduces to one thing: does one model generalizing across bodies create enough lock-in before open-source (GR00T is partly open) + Physical Intelligence + builders' in-house brains commoditize the layer? `` — unproven.
n/a — private, not disclosed. There is no segment-level revenue/EBITDA/geography breakout for a private company at this stage, and segments.csv is header-only. The only disclosed revenue datum is the aggregate ~$30M "live revenue," 2025, with no split by sector, customer, or geography. By deployment vertical (a qualitative proxy, not revenue): security, construction, delivery, data centers, warehouses, factory assembly — with factory assembly (Foxconn/Blackwell) the lighthouse. Treat any finer breakdown as unsourced.
The defining feature is velocity: $1.5B → $14B+ in ~18 months.
| Round | Date | Amount | Post-$ valuation | Lead / notable | Source |
|---|---|---|---|---|---|
| Seed | 2023 | ~$14.5M | n/a | Lightspeed + Sequoia (co-led) — per Sacra; unconfirmed elsewhere | |
| Series A | Jul 2024 | $300M | $1.5B | Lightspeed, Coatue, SoftBank, Bezos Expeditions, Khosla | |
| Series B | May 2025 | $500M | ~$4.5–4.7B | SoftBank (lead), LG Tech Ventures, Samsung, NVIDIA | |
| Series C | Jan 2026 | ~$1.4B | >$14B | SoftBank (lead), NVentures, Macquarie, Bezos |
Cumulative raised: ~$1.8B (PitchBook/Tracxn report $1.81B over 4 rounds, 30 investors). Some sector trackers say "total funding now exceeds $2B" — minor conflict; treat ~$1.8B as the disciplined figure.
Valuation step-ups: A→B ≈ 3.0–3.1×; B→C ≈ 3.0× — i.e. the price roughly tripled at each of the last two rounds in <12 months between B and C. Crunchbase's framing: "tripling valuation to $14B in just 7 months".
Burn / traction signal. Revenue 0 → ~$30M in months in 2025. Against a >$14B post-money, that is a ~470× EV/run-rate-revenue mark. Even on a generous forward ARR, this is a pure option value price on owning the robot-software layer — not a multiple any operating metric supports. Headcount is small and capital-light by hardware standards: ~50–64 employees (Tracxn: 64 as of 2026-03-31; PitchBook/Datanyze: ~50). Implication: the ~$1.8B raised is almost entirely compute + data + research talent, not plant — consistent with the no-hardware thesis.
⚠ Conflict to surface (provenance discipline): Sacra labels the latest round "Series B, March 2026, $1.4B at $15B" and adds a 2023 seed of $14.5M; the company's own blog + BusinessWire + TechCrunch call it Series C, Jan 2026, $1.4B at >$14B. I weight the primary-source ($14B+ Series C, Jan 2026) and flag Sacra's $15B/round-label as a secondary discrepancy, not silently averaged.
No earnings calls exist. The narrative surface is founder interviews + launch posts:
Syndicate quality — the IPO-proximity tell. The Series C cap table is unusually strong on crossover / strategic capital:

| Physical Intelligence | Pure model-lab | $5.6B (Nov 2025), chasing >$11B | >$1B | |
| Covariant | Manipulation model (acqui-hired → Amazon) | ~$625M (pre-acqui-hire) | ~$222M | |

Secondary marks: No disclosed mutual-fund markups/markdowns or tender pricing — n/a. Read: Skild is the best-capitalized, most strategically-syndicated pure model-lab, priced at ~2.5× Physical Intelligence's last mark. That premium is the bet that Skild's omni-body + Foxconn proof-point makes it the category winner. There is no traditional multiple to anchor it — write multiples as n/a — pre-revenue-scale.
The "tape" for a private is the markup ladder + product/deal milestones:
Pattern: the market (private investors) re-rates Skild on (1) SoftBank/NVIDIA conviction events and (2) credibility milestones (HPE compute, the brain demo, the Foxconn line). What it has NOT yet re-rated on is audited deployment economics — because none exist. The next re-rate (up or down) hinges on whether the Foxconn line ships throughput numbers.
Deepak Pathak (Co-founder/CEO). IIT (gold medal 2014) → PhD AI, UC Berkeley → co-founded VisageMap (acquired by FaceFirst, 2015) → Facebook AI Research (2019) → CMU Robotics faculty. Authored the seminal "artificial curiosity" intrinsic-motivation paper (~4K cites). Track record: genuine research leadership + one prior (small) startup exit. First time running a company at this scale/capital — the open question is operator-vs-researcher (see red flags).
Abhinav Gupta (Co-founder/President). IIT → PhD 2004 → CMU Robotics Institute professor (2009) → founding member of Meta FAIR (2018). ~75K citations across manipulation/locomotion/navigation — one of the most-cited robot-learning researchers alive. They jointly won Best Robotic System Award at CoRL (2021–22) for large-scale adaptive sim2real — the literal technical seed of Skild. They reportedly discussed founding a company together for "nearly a decade" before launching.
Skin in the game / tenure. Founders since May 2023; founder equity meaningful but undisclosed ``. CMU itself is on the cap table (alumni/IP alignment). No insider-transaction data exists for a private — insider-transactions.csv absent.
Capital allocation. Two years in, the decision set is: (a) no hardware — capital goes to compute/data/talent, not plant; (b) raise aggressively and bank optionality (~$1.8B); (c) buy credibility via strategics (NVIDIA/Samsung/LG/Schneider as distribution). For a model-lab this is coherent capital allocation — concentrate spend where the moat (research + data + compute) actually is. The risk is over-raising into a valuation that pre-commits them to a winner-take-all outcome they may not achieve.
Red flags (management-specific):
No audited financials exist — so "forensic accounting" reduces to disclosure quality + governance signals, all ``, unaudited.
The headline red flag — the missing Form D. Technical.ly's analysis found that Skild's announced raises are not backed by Form D filings under the Skild name with the SEC. The only "Skild" Form D is a special-purpose vehicle (May filing) logging just over $1M raised — against the $814M total PitchBook reported at the time, and despite the $500M (Apr 2025) and $300M (Jul 2024) rounds. Startups are required to file Form D (Reg D exemption), though they may file under an alias.
[fact]. It belongs at the top of the diligence list (Lens 14, Q-priority).Revenue-claim verifiability. The "0 → ~$30M live revenue in months" figure is company-sourced (the Series C blog), uncorroborated by any filing. Standard for a private — but combined with the Form-D gap, the prudent stance is to discount self-reported traction until a strategic partner or filing corroborates it.
Regulatory / legal findings (required sub-section).
total_sec_findings: 0."Skild AI" (FTC OR DOJ OR lawsuit OR litigation OR fine OR penalty OR investigation) returned no Skild-specific enforcement or litigation — only general AI-enforcement-trend coverage. No consent decrees, fines, or settlements found.Note: research/private-watch.json has no Skild entry, so there is no pre-graded stage/ipo_readiness/catalyst to anchor — this is my `` against the schema's 1–5 readiness scale (1 early → 5 S-1 filed/IPO imminent). (Wave boundary: I do NOT write this back into private-watch.json — that edit is out of scope for this unattended run; flagged below as a follow-up for Connor.)
Estimated IPO-readiness: 3 / 5 (late-stage), trending toward 4. Reasoning:
Milestones that unlock an S-1 (the gating path):
Estimated window: No realistic IPO before 2028–2029 ``. Before then, the tradeable event is far more likely a structured secondary / tender (the syndicate quality supports one) or — a real tail risk — acquisition by a strategic (NVIDIA, SoftBank-orchestrated, or a body-maker buying the brain). Covariant's acqui-hire into Amazon is the cautionary template for how a model-lab can get absorbed rather than IPO.
Brier forecast (would-log, but suppressed in --watchlist): "Skild AI files an S-1 or completes an IPO by 2028-12-31 — p ≈ 0.25" ``. Per --watchlist rules and the strict wave boundary, no forecast.ts create is run in this unattended sweep.
Bull case. Value in robotics migrates from the body to the brain, exactly as it did from PC hardware to Windows and from handsets to iOS. Skild is the best-capitalized pure model-lab with the strongest strategic syndicate (NVIDIA + SoftBank + Samsung + LG + Schneider as distribution), a genuinely differentiated omni-body + internet-video-data recipe that sidesteps the fleet-ownership moat trap, top-1% robot-learning founders, and — critically — the first real production deployment (NVIDIA's own Blackwell line via Foxconn) that no other pure model-lab can claim. If one model can truly run any body, Skild becomes the toll road for the entire $22.8B-by-2034 physical-AI layer, and $14B looks early. The secular tailwind (labor automation, 41.2% sector CAGR, 50K+ foundation-model-trained robots by 2026) is as strong as any in tech.
Bear case (permanent-impairment risks).
Pre-mortem (18 months out, thesis broke): The Foxconn/Blackwell deployment underdelivered on throughput; NVIDIA quietly favored GR00T for its own ecosystem; body-makers (ABB/UR/Figure-class) concluded the brain is better built in-house or bought cheaply from a commoditizing field; Skild's ~$30M revenue stalled while burn climbed; a Physical Intelligence or a Chinese model-lab matched the capability at a fraction of the mark; and the Form-D opacity turned into a governance headline during the next raise. The $14B mark became the high-water print.
Are multiples too high? There is no multiple — it's an option price. At $14B on ~$30M unaudited revenue, you are not buying a business; you are buying a call option on owning the robot-OS layer. That can be the right bet — but it is a venture bet priced like a near-certainty.
Contrarian view (what the market refuses to see): The consensus treats "robot foundation model" as the obvious next platform monopoly. The thing being under-weighted: in robotics the body-maker may keep the customer, and the brain may end up the commoditized, NVIDIA-subsidized layer — the inverse of the software-eats-hardware thesis. The most dangerous scenario for Skild isn't a competitor out-modeling them; it's the layer itself not being defensible.

A frontier lab fused into Musk's compute-and-distribution empire — Grok is a fast-following #4 model bankrolled by a $30B/yr capex furnace; the real instrument is now SpaceX equity at a $1.25T mark, not a standalone xAI bet.
One AI model that folds laundry, makes espresso, and assembles boxes — on any robot body. Hardware-agnostic intelligence for physical work.
A genuinely great business priced as a perfect one — 85% growth and 60% adjusted margins are real, but ~55x EV/Sales already discounts flawless execution for years, so the asymmetry is to the downside even if the thesis is right.
