Vyra launches at YC (Fall 2026)

Vyra is an AI video editor that turns raw footage into finished video. You describe the edit in plain language — "cut my clips to the beat and make a color wheel edit" — and Vyra analyses the uploaded footage and returns a finished draft in minutes, with every conventional editing tool (split, ripple, slip, clone, motion graphics, text layers) available in the same conversation rather than buried in a timeline UI. It is built for people who are not editors but still have to ship video, and it connects to Claude, ChatGPT or any MCP client. Founded in 2026 in San Francisco by Caleb Pong (built neural networks for Omoggle, 3M+ users, and Adobe plugins; CS at Brown) and Sulan Zhang (CS and visual arts at Brown; 60k+ creator following as @sulansart). Y Combinator Fall 2026.

Mirrors launches at YC (Fall 2026)

Mirrors builds runnable staging environments for AI agents. It captures production traces from an agent's real sessions, reconstructs a working twin of the internal tools and APIs that agent calls, then replays those sessions against every prompt, model or tool change before it ships — so regressions surface in staging rather than in production. The gap it fills is that agents call bespoke internal services no standard test suite can reproduce, which matters most where a mistake is irreversible: issuing refunds, updating records, sending outbound messages. Founded in 2026 in San Francisco by Aryan Singhal (ML research at UT Austin and UCSB; six AI/ML papers published while in high school, three at NeurIPS). Y Combinator Fall 2026.

SuperRadiant launches at YC (Fall 2026)

SuperRadiant builds Embodied Scientific Intelligence: general-purpose robotic experimentalists that observe, form hypotheses and run experiments in the physical world. The system automates the full experimental loop while staying flexible enough for real discovery work, adapting to changing protocols and new instruments. Founded in 2026 in San Francisco by Cooper Niu, Benedict Quartey and Owen Tower, with a team drawn from Brown, NASA JPL, Fermilab and CERN. Y Combinator Fall 2026.

ORO AI launches at YC (Fall 2026)

ORO AI runs an open benchmark for agentic commerce: builders submit shopping agents that independent validators score against problems that change daily, the best performers earn rewards on Bittensor, and every run produces training data that feeds back into the next generation. Founded in 2026 in Vancouver by Shardul Bansal (ex-AWS, Crucible Labs) and Seth Schilbe (ex-AWS). Y Combinator Fall 2026.

Halmos Labs launches at YC (Fall 2026)

Halmos Labs builds autonomous systems for scientific research: intelligent experimental design software that works out which experiment would reduce uncertainty most, so labs get more information from fewer experiments and fewer experiments per conclusion. The platform runs parallel analyses under many possible assumptions, validates every analysis, and answers open-ended questions about results where fixed workflows fall short, with early work spanning wet-lab experiment design and cancer vaccine manufacturing. Founded in 2026 in Lund, Sweden by Mattias Akke and Linus von Ekensteen Lofgren, who have worked at MIT, AstraZeneca and Danske Bank. Part of Y Combinator's Fall 2026 batch.

Dreamscale Labs launches at YC (Fall 2026)

Dreamscale Labs is building the fastest cloud inference platform for robotics. As complex physical AI models become too large to fit on expensive on-robot GPUs, Dreamscale lets robotics teams offload inference to the cloud and serves it back with real-time latency — so far hitting 40-50% lower latency than existing neoclouds. Its first product is Dropbear. Founded in 2026 in San Francisco by Eric Ren, Kevin Lin, Antoine Nguyen and Chris Yoo.

Talos launches at YC (Fall 2026)

Talos builds predictive maintenance for power infrastructure. It continuously monitors critical power equipment, detects meaningful changes in behaviour, and tells teams where to look before a failure becomes an outage. Founded in 2026 by Kevin Hwang, Amitav Kohli and Himani Musku, the Baltimore-based company is in Y Combinator's Fall 2026 batch.

Ethos Space Resources launches at YC (Summer 2026)

Ethos Space Resources makes solar-grade silicon on the Moon. Demand for AI compute is compounding toward a terawatt a year of new capacity, and once data centres head to orbit it is rocket capacity, not the grid, that caps the buildout — so terawatt-scale AI in space has to be built from mass already outside Earth's gravity well. Ethos melts, electrolyses and purifies lunar regolith in hard vacuum, a single process that yields construction materials, rocket propellant and solar-grade silicon, tested in the company's own lunar environment chamber. The work starts with mining and construction for the first heavy landings: landing pads, propellant for the trip home, and silicon that turns sunlight into more capacity. Founded in 2022 by Ross Centers (Planetary Sunshade Institute) and Brogan BamBrogan (former principal propulsion engineer at SpaceX, co-founder of Hyperloop One), Ethos is based in Los Angeles and is part of Y Combinator's Summer 2026 batch.

Spectre Intelligence launches at YC (Summer 2026)

Spectre Intelligence is a multi-strategy trading firm that trains AI traders instead of hiring human ones. An independent research and trading company built around reasoning under uncertainty, it currently trades in the semiconductor and biotechnology sectors. Founded by Michelle Li (CEO) and Joshua Zyzak, the firm is based in San Francisco and is part of Y Combinator's Summer 2026 batch.
