B

Boardroom A2→B2

C-level relocations from non-DACH markets. Board-meeting fluency, town halls, regulator updates, executive interviews.

C

Engineering A1→B1

International engineers placed in DACH plants. Plant tours, safety briefings, daily-stand-ups, technical specs in German.

D

Partner & family A0→A2

Partners and family of relocated hires. Daily-life German plus social integration. Included in standard programs at no extra cost.

CASE 01

Global Energy Group

Project managers and field engineers · A2 to B1 · 6 months

From English-only site reviews to confident German project handovers in 6 months

The challenge: project teams from three countries had to run weekly site reviews and contractor coordination in German. Standard group classes had failed twice. Individual coaches were assigned, real meeting transcripts were mapped as session input, and role-specific glossaries were built. After three months, project managers ran reviews unassisted. After six months, contractor calls were routinely being held in German. No measured share is published for this, so none is claimed here.

CASE 02

Big-4 Audit, German practice

Senior associates · B1 to B2 · 9 months

From English-only client meetings to fully German audit reviews

The challenge: senior auditors needed to lead client meetings in German and write reviewable findings without translation overhead. The previous provider stopped at general business German. Content was rebuilt around the firm’s own templates, audit terminology and client tone. After nine months, the partners assessed every learner against one criterion: holding client meetings unassisted. Individual results are not published here, and no success quota is claimed for the group.

CASE 03

Nordic Industrial Group

CTO and direct reports · A0 to B1 · 12 months

From zero German to a board update without an interpreter

The challenge: a CTO joining at C-level had no German on day one and a board update in six months. A steep one-to-one program was built with role-anchored grammar, learning coaching for confidence, and weekly board-language drills. Six months in, the first board update happened without an interpreter. Twelve months in, the team also ran annual planning in German.

Frequently asked questions

Are the case studies anonymized?

Yes. Industry, role, level shift and timeline are real. Company name, learner name and any identifying detail are removed. Confidentiality agreements are signed as a default and honoured, even after the engagement closes.

How realistic are the timelines shown here?

They are the actual delivery timelines. They have not been compressed for narrative effect. The cases that ran long are also represented; the fast ones are not cherry-picked. If you want the median, ask in the discovery call and it will be shared.

Can a client case appear here later?

Only with explicit written approval and only after anonymisation. Many clients prefer to stay invisible and that is the default. If you want a case to appear under your real name as a reference for your industry, that is also possible; the text is drafted for your sign-off.

Do you sign NDAs?

Yes. Mutual NDAs are signed at the start of the discovery call if requested. A one-page NDA is also available and can go out first if your legal team prefers a starting draft. Either route is fine.

What does a case typically cost?

The cases shown range from roughly four-figure single-learner pilots to mid five-figure cohort engagements. A one-page price band comes with the discovery-call follow-up. There is no surprise pricing later.
