1. Startup unveils wearable that claims to read brain signals: MIT spinout Alterego demoed a wearable that reads neuromuscular signals, letting users type, search, and use apps silently. CEO Arnav Kapur showed how the device can take notes and hold silent conversations with AI without speaking a word. Beyond boosting productivity in noisy or public settings, it could give a voice to people with ALS and other speaking conditions. You can see it in action here.

2. Cognition AI hits $10.2B valuation: The coding assistant startup has secured $400M in new funding, led by Founders Fund. The news follows its recent acquisition of rival AI coding platform Windsurf. Cognition’s AI coding agent Devin (which helps developers write, debug, and optimize code faster) has surged to $73M in revenue as of June, up from $1M in September 2024.

3. Microsoft locks down $19B in AI cloud capacity: The company has inked a massive deal worth up to $19.4B with Nebius Group. The agreement gives Microsoft access to dedicated AI computing capacity from a new data center in Vineland, NJ, starting later this year. The move comes as the company faces persistent “capacity constrained” conditions. CFO Amy Hood noted ongoing challenges in meeting demand for both internal AI products and Azure services for customers.
