Cool Company Raises · $40.0M

Impossible Objects raises a $40.0M round

Impossible Objects, based in Northbrook, IL, makes Composite-Based Additive Manufacturing (CBAM) systems that bring 3D printing to industrial-scale production. Its CBAM 25 platform prints composite parts — including carbon fiber — at production speeds, standing in for CNC machining and injection moulding rather than for prototyping. Parts are stronger, more precise and geometrically more complex than other additive methods allow, across a wider range of materials. Customers include the U.S. Air Force, the U.S. Army's Rock Island Arsenal — where the technology can support production of up to 10,000 drone bodies a month — the National Institute for Aviation Research, the Oregon Manufacturing Innovation Center and Rochester Institute of Technology.

Cool Company Raises · YC S26

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.
