Khosla-backed Mazama Energy just raised $135M to drill deeper into super-hot-rock geothermal

Khosla‑backed Mazama Energy announced a $135 million financing round led by Centaurus Capital and Doerr Capital, with participation from ConocoPhillips, Shell Ventures and several new backers. The capital will fund horizontal drilling of super‑hot‑rock geothermal wells that can reach 15,000 feet and tap 750 °F (400 °C) reservoirs, creating supercritical water that delivers up to ten times the power of conventional geothermal. Mazama expects each well to generate roughly 15 megawatts, and its first Oregon project, now projected to produce 10 gigawatts of capacity, aims to deliver electricity by next year and reach 200 megawatts by 2030. The company revised its site potential from 5 gigawatts last year to 10 gigawatts, and has already secured land for a second development. The round included Khosla Ventures and Gates Frontier returning as.

💡 By unlocking supercritical geothermal at unprecedented depths, Mazama could supply cheap, carbon‑free power for energy‑intensive AI workloads, reducing reliance on natural‑gas peaker plants.

Comp AI sets eyes on a continuously agentic future for security and…

Comp AI, a cybersecurity and compliance startup founded in January by Lewis Carhart, Claudio Fuentes and Mariano Fuentes, announced a $34 million Series A financing led by Roo Capital and Grand Ventures, bringing its total funding to $37.5 million. Drawing on lessons from their previous venture LeapAI—where manual SOC 2 compliance slowed product development—the trio built an “agentic” platform that automates policy drafting, evidence collection and continuous monitoring of compliance controls. The system also offers AI‑driven penetration testing and aims to keep security postures up‑to‑date as companies deploy new AI agents that could alter permissions or introduce vulnerabilities. Human oversight remains integral, with AI agents handling routine tasks while humans review and approve critical outputs.

💡 Real‑time, AI‑powered compliance monitoring addresses the gap between static audits and the rapid changes introduced by autonomous agents, protecting revenue‑critical security postures.

Aristotle Secures $5M to Replace the Chatbot with High-Dosage AI Tutoring for…

Aristotle, a voice‑first AI tutoring platform, secured $5 million in seed funding from True Ventures, Wicklow Capital, and angel investors including Anthropic and OpenAI. The company, founded by Stanford alumni Shan Reddy, Jaiden Reddy, and Vivek Vajipey, aims to replace traditional tutoring with high‑dosage AI instruction for students aged 13–18. After a closed beta where over 1,000 students logged more than 1,500 hours of one‑on‑one tutoring, Aristotle plans a nationwide launch. The founders emphasize that their system guides students through productive struggle, unlike standard LLM chatbots that merely provide answers.

💡 By delivering personalized, adaptive tutoring at scale, Aristotle could reduce reliance on costly human tutors and address disparities in educational resources across underfunded districts.
