#1 Hidden Champion in Strategy – Highest Client Satisfaction.
In the 2022/23, 2024/25 and 2026/27 Hidden Champions studies, TTE Strategy was ranked #1 in the Strategy category in Germany – three times in a row, ahead of McKinsey, BCG and Bain.
The ranking is based on independent evaluations by more than 1,100 senior decision-makers, who assess strategy consultancies on their ability to develop robust strategies and translate them into tangible results.
Unlike reputation-based rankings, the Hidden Champions study applies a direct, criteria-based benchmark: boutique consultancies are evaluated head-to-head against the global market leaders within the same strategic disciplines. Only firms whose strategy work is rated on par with or superior to McKinsey, BCG and Bain are awarded Hidden Champion status.
TTE Strategy’s repeated top position confirms the consistency of its strategic excellence. It reflects not a one-off result, but a sustained ability to combine strategic clarity, analytical depth and execution strength – and to deliver measurable impact together with leadership teams.

Building on its #1 ranking in the Strategy category, TTE Strategy achieved the highest overall client satisfaction among all Hidden Champions across all disciplines in the 2026/27 evaluation.
Based on independent assessments by more than 1,100 senior decision-makers, the study shows that TTE Strategy’s projects are rated highest in terms of overall consulting performance, outperforming both specialized Hidden Champions and established global players.
This top position reflects not excellence in a single capability, but a consistently superior client experience across strategy development, execution quality, collaboration, and measurable impact. In a benchmarking designed to compare boutique consultancies directly with McKinsey, BCG and Bain, TTE Strategy stands out as the firm that creates the strongest and most sustainable satisfaction among its clients.
