Circle AI: Empowering Talent and Jobs AI Can’t Replace.
Circle is an AI-powered job search platform built for blue-collar, frontline, and small business workers who are left with limited resources and outdated, inefficient ways to find work in a broken job market. We believe technology with AI can fix it. While AI transforms industries, we focus on amplifying human potential – using AI to expand access to opportunity and resources, not replace people.
Our mission is to serve the underserved. We aspire to democratize AI and technology for local workforces – including immigrants and underrepresented communities – and eventually, in the long-term, to build the future of small business ecosystems, where local talent, businesses, and communities grow and thrive together.
