About the Organization EnGen offers an at-scale, AI-powered approach to English instruction, designed to solve a systemic access issue: Adult English learners now represent 1 in 10 working-age adults in the U.S., yet the workforce system serves the needs of just 4% of these workers.A Certified B Corporation, EnGen is filling the gap by partnering with employers, adult educators, workforce development organizations, and state governments to connect job seekers and incumbent workers with English skills, career pathways, and employment in high-demand industries.
