AI Startups to Watch (Sep 29): SiMa.ai, Helix & Quartermaster
AI startups raised over $1.3B in 24 hours: SiMa.ai's $150M for edge chips, Samsung's $1B into Helix and Quartermaster's $140M maritime network.
Six AI startups moved serious money in the last 24 hours, and the pattern is not chatbots: edge silicon that drops into Nvidia's socket, power-first data centers, sensors on ship masts, and software that places the purchase order. Together they raised more than $1.3 billion. Here is what changed and who gets hurt.
SiMa.ai: $150M for edge chips that swap out Nvidia
SiMa.ai is a San Jose physical AI chip and software company founded in 2018 by Krishna Rangasayee, a former Groq chief operating officer. It sells purpose-built systems on chip for robots, drones and vehicles.
It closed an oversubscribed $150 million Series C, taking total funding to $500 million at a $1.45 billion valuation. Fidelity and Amplify co-led, with Dell Technologies Capital, Maverick, Point72, StepStone, J.P. Morgan and Baron Capital joining. The money scales Palette Neat, its open-source agentic development environment for physical AI, and funds a third-generation part promising 1,000 dense TOPS under 80 watts, shipping in the first half of 2028.
The disruption is switching cost: Rangasayee claims twice Nvidia's tokens per second at a fifth of the power, and the module is pin-compatible, so a robot maker can swap parts without a redesign. Source: Forbes Source: SiliconANGLE
Helix Digital Infrastructure: Samsung puts $1B into the buildout
Helix Digital Infrastructure is a US AI infrastructure company launched in June 2026 by KKR and led by former AWS chief executive Adam Selipsky. It bundles land, baseload power, transmission, fiber and Nvidia hardware into one package instead of building them sequentially.
Samsung Group committed $1 billion today, with Samsung Electronics taking $500 million and five affiliates the rest, joining KKR, the Kuwait Investment Authority, Nvidia and Vistra as founding investors on top of more than $10 billion committed at launch.
Samsung is buying captive demand for memory, cooling and batteries, moving from component supplier to infrastructure architect. Helix is a KKR platform company, not a venture-backed startup, and it frames power, not chips, as the binding constraint. Source: CNBC
Quartermaster: $140M to turn ship masts into a data network
Quartermaster is an Arlington, Virginia company founded by chief executive Neil Sobin that mounts weather-hardened cameras and radios on vessel masts, a product called SmartMast, then sells the resulting ocean data to shippers, governments and insurers.
It raised $140 million: a preempted $100 million Series B plus a $40 million debt facility from Stifel, led by Insight Partners with defence investor Overmatch Ventures joining, four months after a $43 million Series A. Hardware is live on 650-plus vessels across 25 countries.

Atomic: $12.5M to let the AI place the order
Atomic is a Boston supply chain platform founded by former Tesla planning leaders Michael Rossiter, Neal Suidan and Jeff Goodrich, incubated at DVx Ventures by ex-Tesla president Jon McNeill. It runs alongside an existing ERP and executes purchasing decisions instead of recommending them.
It raised a $12.5 million Series A co-led by Klass Capital and Madrona, bringing total funding past $15 million. Annual recurring revenue has quintupled since January 2026 per board member McNeill, and DoorDash's DashMart now has about 90 percent of purchasing automated.
That squeezes planning suites from Kinaxis, o9 Solutions, Blue Yonder and SAP, which sell advice to a human planner. Source: TechCrunch Source: PR Newswire
Marble: €6.5M against black-box compliance suites
Marble, a Paris fraud and anti-money-laundering platform founded in 2021 by former Shine executives Arnaud Schwartz and Pascal Delange, sells a no-code product with an open-source core that runs on-premises.
Its €6.5 million Series A, led by Smartfin with ADNEXUS joining, takes total funding to €9 million for AI-assisted rule generation, alert triage and agentic compliance. Customers number more than 100 institutions across 25 countries, protecting over 3 billion transactions a year, and about 70 percent are replacing an existing vendor. Marble targets €5 million in ARR by 2027. Open-source logic means auditors can inspect the decision path, the opposite of licensed black boxes. Source: EU-Startups Source: Marble
Kyndred: €500K for AI companions with memory
Kyndred is a Romanian consumer AI startup founded in 2026 by serial entrepreneurs Rares Mosescu and Alex Bararu, who previously built the tutoring platform Meditatii.ro to more than €15 million in gross merchandise value. It sells subscription characters combining animated avatars, emotion-aware voices and tiered memory, led by a character called Maya.
Early Game Ventures led a €500,000 pre-seed, the first outside money the company took. Maya passed 150 paying customers three months after launch at $24 a month or $199 a year, and Dealroom records roughly $1,500 in monthly recurring revenue. The bet is that relationship-based companions beat transaction-based assistants on app opens, which puts Character.AI and Replika at risk. Source: Tech.eu

Frequently Asked Questions
What are the top AI startups to watch today?
SiMa.ai, Helix Digital Infrastructure and Quartermaster are the startups to watch today. SiMa.ai raised $150 million at a $1.45 billion valuation for edge silicon claiming a fifth of Nvidia's power. Samsung put $1 billion into Helix, and Quartermaster added $140 million for real-time maritime data.
Why is SiMa.ai a threat to Nvidia?
SiMa.ai is a threat because its chip module is designed to drop into Nvidia's socket. Founder Krishna Rangasayee says it delivers twice the tokens per second at a fifth of the power, and the module is pin-compatible, so a robot maker can swap vendors without redesigning hardware. Nvidia's Jetson, Qualcomm and Hailo are exposed.
Why did Samsung invest $1 billion in Helix?
Samsung invested to secure captive demand for its own components. Samsung Electronics and five affiliates joined KKR, the Kuwait Investment Authority, Nvidia and Vistra as founding investors in Helix, which builds AI data centers with power, fiber and land bundled together. Memory, cooling, engineering and batteries are the pull-through.
