The Week’s 10 Biggest Funding Rounds: Agentic AI And Infrastructure Are

Venture capital investment into artificial intelligence and foundational hardware expanded sharply this week as U.S. startups secured billions of dollars in fresh capital across eleven outsized transactions tracked in Crunchbase News's report. San Francisco-based developer Mirendil led the cohort with a 1 billion dollar Series A round to accelerate its agentic artificial intelligence technology for research and development. It was followed closely by Mercor, which secured 750 million dollars in Series D financing at a 20 billion dollar valuation to expand its network connecting artificial intelligence model builders directly with domain specialists.

This review examines the eleven largest announced venture transactions across U.S. technology companies recorded during the weekly tracking window of November 7 through November 13, 2026. The funding slate covers enterprise platforms, specialized manufacturing robotics, hardware engineering environments, financial tools, and neurological drug development. It serves technical leads, machine learning researchers, and enterprise architects evaluating where capital is concentrating across autonomous agent frameworks and high-density compute infrastructure.

01Megarounds for agents and expert training

Venture activity centered around massive early-stage and growth checks dedicated to agentic workflows and model evaluation. Mirendil closed a 1 billion dollar Series A financing led by Kleiner Perkins and Clearlake Capital. The San Francisco startup is deploying this capital into agentic artificial intelligence designed specifically for research and development teams.

Mercor secured 750 million dollars in Series D funding backed by a broad consortium of venture investors. Founded less than four years ago in San Francisco, the startup reached a 20 billion dollar post-money valuation. Mercor operates a specialized talent network that pairs artificial intelligence developers with human subject-matter experts for advanced model training and evaluation.

LangChain raised 300 million dollars in a Series C financing round led by CapitalG, reaching a 3 billion dollar valuation. The four-year-old San Francisco company provides an orchestration and governance platform that allows software teams to build, run, evaluate, and monitor autonomous software agents in production environments.

02Dedicated capital for compute and physical manufacturing

Capital providers also directed large growth checks into operational facilities and high-density computing infrastructure. Salt Lake City-based Torus announced 500 million dollars in growth financing led by Magnetar Capital to scale distributed power and compute installations. Torus paired the capital announcement with the introduction of Foundry, a modular hardware infrastructure platform engineered specifically for artificial intelligence inference compute.

Columbus, Ohio-based Path Robotics picked up 300 million dollars in Series E financing led by Georgian. The investment valued the robotics developer at 2.45 billion dollars. Path Robotics develops physical artificial intelligence software and machinery for industrial manufacturing lines, focusing initially on autonomous welding tasks for heavy manufacturing setups.

Nominal landed 240 million dollars in funding led jointly by Lightspeed Venture Partners and Insight Partners. The round established a 3 billion dollar valuation for the Austin-based company. Nominal designs intelligence software and workflows targeted directly at hardware engineering teams building complex physical systems.

03Standardization protocols for deployed model infrastructure

Enterprise infrastructure requirements drove nine-figure rounds into operational deployment standards and sales execution software. Mavria emerged publicly after securing 130 million dollars in cumulative pre-seed and seed financing, concluding with a round led by Paradigm.

Founded by former U.S. Department of Energy personnel, the startup reached a 1 billion dollar valuation to standardize how enterprise artificial intelligence infrastructure is engineered, assembled, and deployed.

San Francisco-based software startup Rox closed a 100 million dollar Series B financing round led by General Catalyst and March Capital. Rox manufactures autonomous revenue agents engineered to execute repetitive enterprise sales and customer outreach tasks.

These investments reflect an enterprise emphasis on repeatable infrastructure configurations over custom manual builds. Infrastructure teams are purchasing pre-engineered deployment standards and modular power units to shorten the operational turnaround required to stand up specialized model inference clusters.

04Market data infrastructure and branded payment systems

Financial platforms and data distributors accounted for two major nine-figure capitalization events during the tracking period. New York-based financial technology company Imprint raised 130 million dollars in a funding round led by Khosla Ventures. The six-year-old startup reached a valuation of 1.9 billion dollars while expanding its integrated payments, brand loyalty programs, and customer intelligence platforms.

Salt Lake City-based Databento secured 100 million dollars in Series C funding at a 1.1 billion dollar valuation, with Fifth Down Capital leading the financing. Databento provides financial market data feeds and application programming interfaces for algorithmic traders, asset managers, and financial engineering teams requiring low-latency market inputs.

Both transactions demonstrate continued venture backing for specialized data pipes and transactional plumbing that serve institutional enterprises alongside machine learning systems. These platforms give quantitative developers and consumer brands direct access to standardized transactional rails and regulatory compliance tooling.

05Neurological medicine from reverse-engineered molecular structures

Biotechnology produced one of the week's notable nine-figure growth checks, focusing on neuropsychiatric conditions. Bedford, Massachusetts-based startup Delix Therapeutics closed 100 million dollars in Series C financing led jointly by Johnson & Johnson Innovation and SV Health Investors' Dementia Discovery Fund.

Delix Therapeutics develops medical therapies for psychiatric and psychological disorders by reverse-engineering and optimizing molecular structures derived from psychedelics. The company designs these synthetic compounds to stimulate neuroplasticity without inducing hallucinogenic side effects for clinical patients.

The investment reflects sustained pharmaceutical backing for scalable, non-hallucinogenic neuroplasticity compounds aimed at severe mental health indications. Backers like the Dementia Discovery Fund and corporate pharmaceutical venture arms are seeking non-invasive treatments that fit existing outpatient healthcare delivery models.
