Odyssey led with $310M.' categories: - Weekly Funding Roundup image: 'https://qubit.capital/wp-content/uploads/2026/06/featured-us-series-bplus-67853.webp' published: true --- # US Series B+ Weekly Funding Roundup (Jun 15-22, 2026): $910.0M Raised Across 4 Deals Four US startups at Series B and later stages pulled in $910 million this week. The money spread across world-model AI, offensive cyber, quantum hardware, and IT operations software. The smallest of the four rounds still cleared $100 million, which tells you late-stage capital keeps flowing to companies with a clear technical lead and real demand from government or enterprise buyers. The late-stage figure ran well ahead of the seed end of the US market, where three companies raised a combined $156 million over the same stretch. Odyssey took the largest single check at $310 million, while NinjaOne’s extension round lifted its valuation to $12.3 billion. Two of the four rounds drew In-Q-Tel, the CIA-linked strategic investor, a sign of how closely national security money now tracks frontier AI and computing.

Odyssey Raises $310M For AI World Models ### Deal Overview - **Stage:** Series B - **Sector:** AI world models - **Geography:** Palo Alto, California - **Round size:** $310 million - **Valuation:** $1.45 billion ### Investor Profile Natural Capital, Amazon, AMD Ventures, GV (Google Ventures), EQT Ventures, and In-Q-Tel backed the round. The Amazon tie comes with a strategic deal that makes AWS Odyssey’s preferred cloud provider and commits the company to optimizing its models for AWS Trainium chips. That gives Odyssey a cheaper compute path than rivals who depend on Nvidia. ### Company and Leadership [Odyssey](https://odyssey.ml) was founded in 2023 by CEO Oliver Cameron and CTO Jeff Hawke. Cameron co-founded self-driving startup Voyage, which GM’s Cruise acquired, where he then ran product. Hawke was a senior engineer at UK self-driving company Wayve. The cap table reads like a who’s who of AI: Google chief scientist Jeff Dean, Elad Gil, Y Combinator’s Garry Tan, Vercel’s Guillermo Rauch, and Cruise founder Kyle Vogt. Total funding now sits near $337 million. ### Problem and Opportunity Most generative AI produces text or static video. Odyssey wants AI that simulates the physical world with accurate physics. That capability matters for gaming, film, and training robots, all fields where a model needs to understand cause and effect, not just predict the next word. ### Product and Technology Odyssey’s signature feature is interactive video: footage you watch and control at the same time, with the model generating new frames every 40 to 50 milliseconds in response to your inputs. Its systems include Odyssey-2 Max for physics simulation, Starchild-1 (billed as the first real-time multimodal world model), and Agora-1, which lets multiple agents share one simulation. To gather training data, the team strapped cameras to people’s backs and sent them out, borrowing Google Earth’s playbook. ### Use of Proceeds and Vision The capital funds faster development of Odyssey’s world models, with a heavy compute component tied to the AWS partnership. Cameron’s team frames world simulation as the next major shift in AI, beyond chat-based language models, and wants Odyssey to be an independent world-model lab rather than a niche video tool. ### Market Context World models have become one of the most capital-hungry corners of AI over the past 18 months. Competitors include World Labs (Fei-Fei Li’s startup, over $1 billion raised), Runway, Decart, AMI Labs, General Intuition, and Google’s Project Genie. Hyperscalers and chipmakers are racing to back the leaders, since world simulation sits at the meeting point of generative media, gaming, and robotics. ## 2. Twenty Raises $100M For AI Cyber Warfare ### Deal Overview - **Stage:** Series B - **Sector:** Cybersecurity, defense tech - **Geography:** Arlington, Virginia - **Round size:** $100 million - **Valuation:** $1 billion ### Investor Profile Accel led, with Friends & Family Capital, Point72 Ventures, Caffeinated Capital, General Catalyst, and In-Q-Tel joining. In-Q-Tel’s involvement, the CIA’s strategic investment arm, signals deep credibility with the government buyers Twenty sells to. ### Company and Leadership [Twenty](https://twenty.io) was founded in 2024 by Joe Lin (CEO), Leo Olson, Skyler Onken, and Pete Sorrentino. Lin ran Palo Alto Networks’ National Security Division after the company bought Expanse, a unit he started, for $1.25 billion, and he served as a Navy Reserve officer. Olson built Palo Alto Networks’ first cyber operations product, used by the US government, Five Eyes, and NATO. Onken spent more than a decade at US Cyber Command as one of the military’s first Master Cyber Operators. A prior $38 million round brings total funding to $138 million. ### Problem and Opportunity Offensive cyber operations have stayed bespoke, manual, and operator-bound for years. The US faces sustained attacks from state actors, and the White House has made offensive cyber a priority. Twenty wants to industrialize that work so a small team can run many operations at once. ### Product and Technology Twenty builds end-to-end offensive cyber systems for the US military and Intelligence Community. It deploys networks of AI agents that orchestrate each phase of the cyber kill chain in parallel, compressing weeks of manual work into machine-speed operations across hundreds of targets. The company keeps human judgment central, pairing automation with evaluation and controlled deployment. ### Use of Proceeds and Vision The money scales Twenty’s systems for US and allied missions, expands its engineering and operator teams, and speeds development of its agentic kill-chain platform. Lin argues that adversaries attack because the attacks rarely carry consequences, and he positions Twenty as the company built to impose them. ### Market Context Twenty sits at the intersection of defense tech and cybersecurity, near peers like Anduril and Palantir, though it focuses on AI-driven offense for government customers. Global cybersecurity spending runs into the hundreds of billions a year, and defense cyber budgets are climbing. Twenty calls itself America’s first VC-backed cyber warfare startup, which gives it first-mover positioning in a category investors are warming to. ## 3. Atom Computing Raises $100M For Quantum Hardware ### Deal Overview - **Stage:** Series C - **Sector:** Deep tech, quantum computing - **Geography:** Berkeley, California - **Round size:** $100 million (part of more than $300 million total) - **Backing:** Includes a signed US Department of Commerce letter of intent ### Investor Profile Third Point Ventures, DCVC, and Cisco Investments backed the Series C, alongside a $100 million letter of intent from the US Department of Commerce. Government interest like this is becoming a real signal in quantum, where buyers want to lock in domestic capability early. ### Company and Leadership [Atom Computing](https://atom-computing.com) was founded in January 2018 by Ben Bloom and Jonathan King, with offices in Berkeley and Boulder, Colorado. Bloom holds a physics PhD from the University of Colorado-Boulder, where he helped build one of the world’s most accurate atomic clocks. He later worked on Intel’s 10nm process and led R&D on the first cloud-accessible quantum computer at Rigetti. The company started with a $5 million seed and has now raised more than $300 million. ### Problem and Opportunity Fault tolerance is the hard problem in quantum computing. Errors pile up faster than most machines can correct them. Atom bets that neutral atoms offer the most practical route to error-corrected machines, since they resist noise and cost less to produce than superconducting qubits that need extreme cryogenic gear. ### Product and Technology Atom builds neutral-atom quantum computers from arrays of optically trapped atoms. It was the first to cross 1,000 qubits for universal gate-based systems and among the first to publicly show quantum error correction on neutral-atom hardware. Microsoft has folded Atom’s hardware into its quantum offerings, the company works with Nvidia and Cisco, and it reached Stage B of DARPA’s Quantum Benchmarking Initiative. ### Use of Proceeds and Vision Funds go toward higher qubit counts, better gate fidelity, and software for control and error correction. Atom also plans more on-premises deployments for enterprise and government customers. The stated goal is the first fault-tolerant, commercially viable quantum computer. ### Market Context The race to commercialize fault-tolerant quantum pits neutral atoms against superconducting (IBM, Google), trapped-ion, and photonic designs. Atom’s closest neutral-atom rival is QuEra Computing, which targets 2028 commercialization with AWS, while Pasqal and IonQ also compete. Governments now treat quantum as strategic infrastructure, and the market is projected to grow into the tens of billions over the next decade. ## 4. NinjaOne Raises Over $400M At $12.3B Valuation ### Deal Overview - **Stage:** Series C extension - **Sector:** SaaS, IT operations - **Geography:** Austin, Texas - **Round size:** Over $400 million - **Valuation:** $12.3 billion ### Investor Profile Wellington Management, Sequoia Capital, ICONIQ, CapitalG (Alphabet’s growth fund), NEA, Teachers’ Venture Growth, BDT & MSD Partners, and Hedosophia took part. The round more than doubled the $5 billion valuation NinjaOne carried after its early 2025 extension, and the company stays founder-controlled and debt-free. ### Company and Leadership [NinjaOne](https://www.ninjaone.com) was founded in 2013 as NinjaRMM by Sal Sferlazza (CEO), Christopher Matarese (President), and Richard Whaley. Sferlazza and Matarese had sold an earlier startup, Realm Interactive, together before building NinjaOne. The company ran in stealth in San Francisco, launched its platform in 2015, and has compounded since. ### Problem and Opportunity IT teams juggle too many tools. Patching, backup, device management, and remote access often live in separate products that don’t talk to each other. NinjaOne pitches a single console to replace that sprawl, which lines up with a clear 2026 buyer trend toward fewer vendors. ### Product and Technology NinjaOne runs a cloud-native Unified IT Operations Platform covering endpoint management, autonomous patching, vulnerability remediation, backup, mobile device management, and remote access. It’s adding AI throughout, including patch intelligence for Windows updates and AI-assisted helpdesk features, across roughly 20 recent releases. In mid-2025 it bought Dropsuite for about $270 million to deepen its data protection. ### Use of Proceeds and Vision The capital funds R&D into autonomous endpoint management, automated remediation, and AI helpdesk tools, plus global expansion and customer success. NinjaOne has signaled appetite for more acquisitions and wants to be the control plane for unified IT. At roughly 70% year-over-year growth, it’s increasingly seen as an IPO candidate. ### Market Context NinjaOne competes in RMM and endpoint management against ConnectWise, Kaseya, Datto, Atera, N-able, Syncro, SuperOps, and Pulseway. It calls itself the fastest-growing RMM, with nearly 40,000 customers across 140-plus countries and more than $500 million in ARR. Published per-endpoint pricing, cloud-native architecture, and Gartner recognition set it apart from single-point tools. Clients include Audi, Porsche, Hyundai, Deloitte, and Carnival Cruise Line. ## Lessons For Founders - Government money is now a frontier-tech signal, not a side channel. In-Q-Tel and the Department of Commerce showed up in three of these four rounds, and that backing opens doors with buyers who are hard to reach otherwise. - A real compute advantage moves valuations. Odyssey’s AWS Trainium deal and Atom’s lower-cost neutral-atom approach both cut the cost curve, and investors paid up for it. - Founders with hard-won domain credentials raise faster. Self-driving veterans, Cyber Command operators, and atomic-clock physicists anchored these companies, and that track record did real work in the pitch. - Consolidation sells in 2026. NinjaOne’s single-console story rides a clear buyer shift away from tool sprawl, and capital efficiency (debt-free, founder-controlled) made the growth story more credible. - Pick a category you can own. Twenty branded itself the first VC-backed cyber warfare startup and Atom leaned on quantum firsts. Clear category leadership is easier to fund than a crowded middle.
