Accelevation Bet $50 Million That the AI Boom Needs a Factory Floor
The Ohio manufacturer survived a shutdown-era order collapse, found a wedge in polycarbonate panels and built its way into power, steel and field installation. Its real product is not a door or a cable - it is fewer handoffs on a data-center schedule.
AttoTude
AttoTude is a Menlo Park, California deep-tech startup building the world's first THz (terahertz) radio over wire - an interconnect platform that moves data between AI servers and GPUs at hundreds of gigabits per second over standard wire, without photonics or exotic packaging. Founded in 2024 by optical-networking veteran Dave Welch and RF/semiconductor pioneer Joy Laskar, the company adapts fiber-grade signaling to terahertz frequencies on low-cost ASICs to break the bandwidth, power, and reliability bottlenecks choking AI data centers. It came out of stealth at OFC 2025 and has raised roughly $91M total, including a $50M Series B led by Mayfield.
