    "post_text": "Quick roundup of the most interesting startup / indie hacker stories from the last 24 hours.\n\n1. Nvidia ships CUDA Rust - native GPU kernels without C Nvidia officially released CUDA Rust: two tracks for writing GPU kernels directly in Rust. cuda-oxide follows the traditional SIMT model (early alpha, requires nightly Rust). cutile-rs uses the newer tile model and runs on stable Rust 1.89+. No more wrapping C code - Rust's ownership system catches memory aliasing bugs at compile time. The HN post hit 804 points today. Already used in HuggingFace's Grout and mistral.rs outside Nvidia.\n\n2. Crusoe raises $3.9B at a ~$31B valuation for AI-native data centers Crusoe Energy closed a $3.9B round as it builds \"Spark\" - modular data centers designed specifically for AI workloads. The thesis: traditional data center formats were built for web apps, not for GPU clusters that scale unpredictably. At a $31B valuation, this is one of the biggest AI infrastructure bets of the year.\n\n3. Fortell raises $163M to crack the hearing aid monopoly Five companies control roughly 80% of the $10B+ hearing aid market. Fortell is going after them with AI-personalized sound processing and a direct-to-consumer model - roughly half the cost of traditional hearing aids. The $163M raise is the Warby Parker playbook applied to a medical device category that hasn't seen real competition in decades.\n\n4. CREEM 2.0...",
