Edexia
Edexia is a Brisbane-founded, Y Combinator-backed (W25) AI teaching assistant that grades essays and written work in each teacher's own marking style.

Pangram Labs
Pangram Labs builds AI-content detection software that identifies text written by models like ChatGPT, Claude, Gemini and Grok. Founded in 2024 by Stanford classmates Max Spero and Bradley Emi, the New York-based startup claims third-party-verified accuracy above 99.9% and a roughly 1-in-10,000 false-positive rate, positioning itself as the reliable alternative to perplexity-based detectors. Its detector, browser extensions, API and LMS integrations are used across education, publishing, enterprise trust & safety and platform moderation.
Clarity
Clarity is an AI cybersecurity company that detects deepfakes, voice clones, and synthetic identities. Founded in 2022 by alumni of Israel's 8200 unit and Stanford, it began as a broad deepfake-forensics platform and has sharpened into hiring security - an end-to-end overlay that verifies applications, spots manipulated faces and voices in live video interviews, and flags proxy candidates before a fraudster ever gets onboarded. It raised a $16M seed in 2024 led by Walden Catalyst Ventures and Bessemer Venture Partners.
GPTZero
GPTZero is a New York-based AI startup that builds tools to detect AI-generated text and verify human authorship. Launched in January 2023 by Princeton senior Edward Tian, it grew from a viral side project into a profitable company serving over 10 million users and 100+ organizations across education, hiring, publishing, and legal. Its mission is to restore trust and transparency to writing on the internet as large language models flood it with machine-made text.
