GlobalFoundries is betting real fab capacity on it.*\n\nKepler Computing spent eight years and burned through 35 failed material formulas before landing on what it's now calling a breakthrough: a ferroelectric composite that boosts the density of SRAM while cutting the voltage needed to read and write it. According to Wired's report on the previously stealth Moraga, California startup, that combination could make HBM-adjacent memory chips both cheaper and easier to manufacture, arriving at the exact moment the AI industry can't get enough of them.\n\nThe company is run by CEO Debo Olaosebikan, who founded Kepler in 2018, and CTO Sasi Manipatruni. \"We came up with a material innovation that helps with the amount of memory you can have between chips,\" Manipatruni told Wired. It took 35 iterations of the composite before the team found a material class they believed would actually hold up in production, not just in a lab.\n\nThat's the part worth pausing on. Material science breakthroughs are common in press releases and rare in fabs.\n\nKepler isn't just claiming a lab result. It's already working with GlobalFoundries, and the two say they converted a fab line to next-generation status in eight months, versus the roughly 24 months that kind of conversion normally takes. A GlobalFoundries executive told Wired that iron, a key ingredient in Kepler's composite, is \"a tough contaminant to introduce into a production facility,\" which is why the work needed dedicated or fully encapsulated equipment rather than a shared line.\n\n[China's OpenBMB Releases MiniCPM5-2B, Beating Every Open Model Under 4B](https://startupfortune.com/chinas-openbmb-releases-minicpm5-2b-beating-every-open-model-under-4b/)\n\nOpenBMB released MiniCPM5-2B on September 7, a 2.52-billion-parameter open model that tops the Artificial Analysis Intelligence Index among all models under 4 billion parameters, beating Qwen3.5-4B despite having roughly half the size. The Tsinghua NLP Lab and ModelBest joint venture also published its full training data, RL corpus, and... - [open source small language models 2B parameters](https://startupfortune.com/chinas-openbmb-releases-minicpm5-2b-beating-every-open-model-under-4b/) - [MiniCPM5-2B beats Qwen3.5-4B benchmark performance](https://startupfortune.com/chinas-openbmb-releases-minicpm5-2b-beating-every-open-model-under-4b/)\n\nHere's the honest caveat: Kepler has only run its process on around 2,000 wafers so far. Scaling from a few thousand test wafers to the millions of devices a real memory supply chain needs is a different problem entirely, and GlobalFoundries' own executive said as much to Wired. Plenty of promising memory materials have died exactly at that step.\n\nKepler's timeline is aggressive. The company says it plans to ship its first HBM chip samples later this year, ramp production out of Singapore in 2027, and start US chip production in 2028. Those are the kind of dates that slip in the semiconductor industry more often than they hold.\n\nThe money behind Kepler suggests investors and the US government aren't treating this as vaporware. In July, the Commerce Department announced $874 million in CHIPS Act letters of intent across seven companies aimed at AI compute supply chain gaps, and Kepler landed up to $245 million of it, the largest award of the group behind GlobalFoundries itself. According to PitchBook, Kepler has raised $662.8 million total and carried a $1.9 billion valuation as of mid-2025.\n\n## Why the timing matters\n\nFrankly, the industry needs something to work. AI data centers are now consuming roughly 70% of high-end DRAM production, according to reporting on the 2026 memory market, an inversion of a market that used to be dominated by phones and PCs. Hard drive and SSD prices have followed: 4TB SATA drives that sold for around $120 a year ago now go for about $240, and 8TB models have doubled from roughly $200 to $400. NAND flash pricing has climbed close to fourfold off its recent lows.\n\nWestern Digital's CEO has said the company is sold out of hard drive capacity for all of calendar 2026, with supply agreements already locked in through 2027 and 2028 for some customers. New fab capacity that could ease the crunch isn't expected in volume before 2027 at the earliest.\n\nThat's the gap Kepler is trying to fill. Whether a ferroelectric composite tested on 2,000 wafers can actually close it is the question nobody, including Kepler, has answered yet.\n\n**Also read:** [Lyft Starts Putting Waymo Robotaxis Inside Its Own App in Nashville](https://startupfortune.com/lyft-starts-putting-waymo-robotaxis-inside-its-own-app-in-nashville/) • [Saudi's Humain Preps IPO and 2.5 Billion Dollar Fund to Build AI Data Centers](https://startupfortune.com/saudis-humain-preps-ipo-and-25-billion-dollar-fund-to-build-ai-data-centers/) • [Beyond Smartphones: How AI Wearables Are Rewiring Everyday Life](https://startupfortune.com/beyond-smartphones-how-ai-wearables-are-rewiring-everyday-life/)\n\n[Giving Your AI Agent an Email Address Is Now a Real Product Category](https://startupfortune.com/giving-your-ai-agent-an-email-address-is-now-a-real-product-category/)\n\nAI agents can send email easily, but receiving replies and holding a thread together is still the hard part.
