Top SaaS Startups in 2026

GPTZero is building an internet for humans, by humans. Our goal is to build the verification layer for the world’s information. Our initial launch and call for AI transparency captured the nation’s attention. We’ve been covered on the front page of the NYT, WSJ, WaPo, Fox, NPR, and CNN, 6x on the BBC, and internationally in 30 countries. Our team comes from high-performing engineering cultures, including Uber, Meta, Microsoft, Affirm, and leading AI research labs, including Princeton, Caltech, Vector, and MILA. We are working on novel models and pushing cutting-edge research to production, including AI detection, AI hallucination detection, retrieval augmented generation, and writing stylometry to over 3 million active users, and enterprise clients including Fortune 1000 and Unicorn AI companies. We are backed by some of the best in the valley, including Uncork, Neo, Altman Capital, and in journalism, including Mark Thompson (CEO of NYT, BBC, CNN) and Tom Glocer (CEO of Reuters) who defined a generation of quality digital information. Underneath the headlines, we are a nerdy and fun-loving group looking for people who are passionate about our mission to join us!

Circularise is a supply chain traceability platform. We help manufacturers collect, verify, and share sustainability data across complex supply chains — and produce the digital product passports, mass balance reports, and compliance documentation their customers and regulators require. We were founded in The Hague in 2016. Our customers include large manufacturers in automotive, batteries, chemicals, and plastics. The platform lets companies share what they need to without exposing commercially sensitive information.
