Upstack.AI is an AI-powered hiring and training platform that helps organizations screen candidates and train employees using assessment technology proven in world-class universities. The platform combines two integrated solutions: WorkLab — AI-Powered Recruitment WorkLab automates candidate screening by generating dynamic, role-specific assessments that evaluate technical skills, problem-solving ability, and cultural fit. The AI conducts conversational interviews, technical evaluations, and practical task assessments—delivering a ranked shortlist of qualified candidates. Organizations typically reduce screening time from 80+ hours to under 5 hours per role. LearnLab — AI-Powered Training & Education LearnLab enables educators and corporate trainers to create courses, generate assessments, and grade submissions using AI. The platform uniquely handles complex STEM content with publication-ready LaTeX mathematics support—a capability developed through partnership with Instituto Superior Técnico Lisboa, Portugal's top engineering university.
