About us

What is Achivr?

Achivr is a corporate business English education company, built for firms that run and operate in English. We don't run classic language courses. We build measurable business communication programs and combine one-on-one mentoring with native speakers and our own AI platform, giving management clear visibility into employee progress and program ROI.

At the heart of our work is BASTION, our AI platform that analyzes data from every session and shows HR and management progress, employees' readiness to work in English, and return on investment, at the individual, team, and company level. We work with international corporations and companies from more than 15 industries, and we're proud to be their first choice for long-term partnership.

Company diagnostic

Map English proficiency across your whole team

Before the program starts, we map business English proficiency across the whole company, by employee, team, and department. AI diagnostics deliver a Communication Index (0–100) and a communication profile across five dimensions, with no subjective judgment calls, so you know exactly where to invest and what to track.
