Your corporate English partner

About Yappi

We’re a corporate English training provider with 19 years of experience helping companies improve workplace communication in English. We focus exclusively on corporate learning, which means we know how to make English training relevant, flexible, and results-driven — whether you’re onboarding five people or scaling training across 500+ employees.

Our methodology combines proven learning approaches (flipped classroom, spaced repetition, and hybrid formats) with modern EdTech — including a CEFR-aligned digital textbook and yCloud, our HR-friendly learning ecosystem for managing programs and tracking learner progress.

Today, we’re expanding our ecosystem with AI-powered tools that support faster learning and better practice between lessons — and we’re actively developing new products to help teams build real communication skills for meetings, emails, presentations, and client calls.

Beyond courses, we offer speaking clubs and skills-based trainings designed for real business tasks. No fluff — just practical English that teams use at work, with measurable progress you can track.

Impact you can measure (and your CFO will love)
