How Deutsche Telekom Drove 19% Sales Growth Across Its Retail Partner Network

Deutsche Telekom, Europe’s largest telecom provider and T-Mobile's parent company, operates a retail partner network of 900+ stores across Germany. The company wanted to build a direct connection with the thousands of salespeople across its partner network, giving them the tools, knowledge, and motivation to sell more confidently and consistently. With Centrical, both salespeople and managers gained real-time visibility into progress and skill gaps, turning those insights into coaching and training that boosted sales and subscriptions.

“The salespeople use Centrical every day, not because their managers tell them to, but because they feel motivated, better informed, and valued. If people are motivated and learning, the sales come automatically.”

Reaching the Frontline in a Partner Network

Deutsche Telekom maintained strong relationships with its partner shop managers but had no direct line to the salespeople those managers supervised. Product knowledge, promotion updates, and brand connection all passed through intermediaries, making it impossible to see whether training was landing or where skill gaps existed. What the company had was a black box: training attendance data, but no visibility into actual learning outcomes or skill development. 

Data governance added another layer of complexity. With multi-brand partners also selling competitor products, any engagement solution had to respect strict information boundaries while still building genuine brand connections at the frontline level.

A Mobile-First Engagement Hub Built for External Salespeople

Deutsche Telekom partnered with Centrical to build the Telekom Partner Hub, a mobile-first platform connecting performance, enablement, and engagement for its external retail workforce. The platform gave frontline salespeople direct access to personalized microlearning, performance visibility, and gamified challenges tied to real selling behaviors. Shop managers gained real-time visibility into team progress and skill gaps, opening up a completely new way of coaching. 

A peer-to-peer kudos system created a culture of recognition that grew organically across stores. For the first time, Deutsche Telekom could reach its frontline directly, sharing updates, celebrating wins, and collecting feedback. Salespeople engaged with the platform on their own terms and at their convenience.
