Deutsche Telekom reported net revenue of 119.1 billion euros for 2025 and cash capex of 19.3 billion euros, of which 16.9 billion was spent outside spectrum. Those are the numbers a vendor quotes in a business case.
The number that shapes how you sell here is a different one. As of 30 June 2026, the Federal Republic of Germany held 14.22 percent of Deutsche Telekom's shares directly, and KfW, the German state development bank, held a further 14.37 percent. Close to twenty-nine percent of this company is the German state, and the chief executive of KfW sits on its Supervisory Board. Digital sovereignty is not a positioning theme at Deutsche Telekom. It is a shareholder with a seat.
The second structural fact is German company law. Deutsche Telekom has two boards, not one. A Board of Management runs the group. A separate Supervisory Board of twenty members appoints and oversees it, and under German co-determination ten of those twenty seats belong to employee representatives. The deputy chair of the Supervisory Board is a member of the national executive board of the union ver.di. If your product changes how work is done in Germany, employee representation is a formal governance stage in the decision, not a courtesy conversation at the end.
How the buying process actually runs
Registration runs through One.Source, not Ariba or Coupa. Deutsche Telekom operates its own supplier portal, One.Source, and its procurement pages publish terms of use for the One.Source 2.0 platform alongside terms for its electronic communication procedures. Before registering you commit to the sustainability, compliance and anti-corruption requirements in the Supplier Code of Conduct, which applies to all new Deutsche Telekom AG suppliers.
Deutsche Telekom tells you plainly that registration is a database. Its own become-a-supplier page says that once you have registered it will add you to its supplier database and will contact potential suppliers whose products or services interest it. That is the entire promise. The portal makes you eligible to be found by a category manager who already has a requirement. It does not create the requirement.
A large part of the spend is not negotiated by Deutsche Telekom alone. Procurement for customer equipment, network technology, information technology and service platforms is bundled into BuyIn, the fifty-fifty procurement joint venture Deutsche Telekom runs with Orange from Brussels, which appointed Michael Rubas as chief executive with effect from 1 June 2026. If your category sits inside BuyIn's scope, the commercial conversation is being conducted against the combined volume of two large European carriers, by a team whose entire reason to exist is leverage. That is a different negotiation from the one you prepared for, and finding out late is expensive.
The requirement originates in a segment. Deutsche Telekom reports Germany, Europe, United States, Systems Solutions and Group Development. These are not departments of one buyer. They run different networks, regulators, currencies and approval chains.
Who owns what, so you know where your deal belongs
You will not be selling to these people. Their remit tells you which part of the group your deal sits inside, and whose priorities it has to survive two or three levels down.
| Name | Role | What it means for a vendor |
|---|---|---|
| Timotheus Höttges | Chairman of the Board of Management | Also chairs the T-Mobile US board, the only formal link between the two buying worlds |
| Rodrigo Diehl | Board member for Germany | The German fixed and mobile business, and the segment where works council involvement bites hardest |
| Dominique Leroy | Board member for Europe | A portfolio of national operators, several separately listed, each with its own board and its own budget |
| Ferri Abolhassan | Board member for T-Systems | The IT services arm, which is the part of the group most likely to be your competitor and your reseller at the same time |
| Thorsten Langheim | Board member for USA and Group Development | The US shareholding, portfolio strategy and group M&A, where partnership and investment conversations land |
Christian P. Illek is Chief Financial Officer and will leave after the 2027 Annual General Meeting for age reasons, with Dhananjay Mirchandani taking the finance portfolio from 1 May 2027. Jan Hofmeyr becomes Board member for Product and Technology on 1 November 2026, succeeding Abdurazak Mudesir, who left in spring 2026, and Mladen Mitic becomes Chief Product and Digital Officer on 1 October 2026. Birgit Bohle holds human resources and legal affairs. Names and dates taken from Deutsche Telekom's own corporate governance and newsroom pages, verified 12 September 2026. Senior roles change. Verify at source before using any name.
You cannot sell into this group from the bottom
Deutsche Telekom employed around 198,000 full-time equivalents at the end of 2025. That is a large organisation, but a centrally procured one, and German approval culture pushes commitments upward rather than devolving them. A deal that repays the cost of a multi-quarter enterprise sale here runs into the millions of euros a year, and anything touching the network runs far beyond that.
The people most likely to answer a cold email are usually the people without budget authority, and the people with it are covered by a category manager whose mandate is to run a competitive process rather than to meet new vendors. Aiming your outreach where replies are easiest aims precisely where the decision is not.
The layer that matters sits below the public names, and it moved recently
Three things make this account unusually hard to map even by the standards of a company this size.
The technology seat has changed twice inside a year. Abdurazak Mudesir left at his own request in spring 2026, the Chief Financial Officer additionally carried the technology function during the transition, and Jan Hofmeyr arrives on 1 November 2026 from Amazon Web Services, where he led the telecom segment, and before that from Comcast. Any product and technology contact map built before 2026 is stale, and the incoming board member brings hyperscaler reference points to every architecture conversation.
T-Mobile US is a separate company that buys separately. Deutsche Telekom holds a majority stake of roughly 52.8 percent, but T-Mobile US is listed on Nasdaq, has its own board and its own procurement organisation, and has been led by Srini Gopalan as chief executive since 1 November 2025. Höttges chairs that board. A master agreement signed in Bonn does not produce a purchase order in Bellevue, and treating the group as one account is the single most common mistake vendors make here.
T-Systems makes Deutsche Telekom a customer, a competitor and a channel at once. T-Systems sells cloud, digital and managed IT services to exactly the enterprises many software vendors target, and in 2026 Deutsche Telekom and NVIDIA launched an Industrial AI Cloud in Munich's Tucherpark, around one billion euros of sovereign AI compute for European industry. Decide before the first meeting which of the three relationships you are proposing, because the room will otherwise assume one of the other two. Naming the buying committee you think you need is the fastest way to settle it.
The Supervisory Board is a published second-degree map
Ten shareholder representatives sit alongside ten employee representatives. The shareholder side is public, checkable, and almost nobody uses it as a routing table.
- Dr. Frank Appel, Chair of the Supervisory Board, formerly Chief Executive Officer of Deutsche Post.
- Stefan B. Wintels, Chief Executive Officer of KfW, which is also one of the two state shareholders.
- Dr. Philipp Herzig, Chief Technology Officer and member of the Extended Board of SAP SE.
- Dr. Thomas Dohmke, co-founder and chief executive of Entire Inc., previously Chief Executive Officer of GitHub.
- Harald Krüger, formerly Chairman of the Board of Management of BMW, also a member of the Supervisory Board of Deutsche Lufthansa.
- Dr. Reinhard Ploss, Chairman of the Supervisory Board of Knorr-Bremse, formerly Chief Executive Officer of Infineon Technologies.
- Rachel Empey, formerly a member of the Board of Management of Fresenius Management SE, with audit committee experience at BMW and ZF Friedrichshafen.
- Natalie Knight, formerly Chief Financial Officer and Executive Committee member of Stellantis.
- Margret Suckale, formerly a member of the Board of Executive Directors of BASF.
Read that as a seller. If anyone in your network is senior at SAP, KfW, Knorr-Bremse, Lufthansa, BMW, Stellantis, BASF, Infineon or DHL Group, there is a two hop path to a Deutsche Telekom Supervisory Board member. The employee side matters too, and differently: Christoph Schmitz-Dethlefsen, the deputy chair, sits on the national executive board of ver.di, so union leadership has a standing view of large change programmes at this company.
The other routes in, including one that does not look like a route
The European national operators. OTE in Greece, Magyar Telekom in Hungary and Hrvatski Telekom in Croatia run their own investor relations and their own boards. A proven deployment inside one of them is the most credible reference you can carry into Bonn, at a fraction of the entry price.
There is no large formal alumni club, but there is an unusual alumni pool. Deutsche Telekom maintains a page for former employees and civil servants, a legacy of its origin in the Deutsche Bundespost, which means the population of people who once worked here and still know who stayed is both enormous and older than the company's listing. Most vendors have never checked whether anyone in their own building belongs to it.
Integrators and partners already inside. The consultancies and integrators already embedded in Telekom Deutschland and T-Systems programmes can route you to the team with the problem, and often want to.
Finding which of these paths already exists in your company's relationships is what relationship intelligence is for. The map is usually already there. Nobody has queried it.
And then you have to get your own connector to act
Suppose the strongest path runs through one of your directors who serves on another board with a Deutsche Telekom Supervisory Board member. That is close to the best case, and close to unrepeatable. You still have to get that person to prioritise it, write something credible, and spend part of a relationship built over years on you. Ask twice in a quarter and you will not be asked again. The same holds at every level, and most companies have no view of who else internally is already asking the same connector this quarter.
Three rules for the introduction itself
Ask for the segment, not the group. An introduction to whoever owns network automation inside Telekom Deutschland is actionable. An introduction to Deutsche Telekom is not, and an introduction that lands in the wrong segment costs you a quarter.
Write the paragraph your connector will forward. They will not write your pitch, and if they have to, they will not send it. The forwardable blurb is the whole craft, and in this account it should say in one line whether you are selling to the group, selling with T-Systems, or competing with it.
A warm path starts the clock, it does not skip it. You still register on One.Source, still sign up to the Supplier Code of Conduct, still face a category process that may be run through BuyIn, and you still need more than one thread inside a group whose technology leadership changes hands. What a warm path buys you is a real conversation with someone who has the problem and the budget, months earlier than cold outreach would produce one.
See the warm paths into Deutsche Telekom
Everything above describes the problem: a procurement joint venture with Orange and a separately listed US subsidiary. What it does not tell you is which of your own relationships already reaches inside. That is a question about your network, not theirs, and it is the one most teams answer from memory.
Boomerang maps the warm paths your company already has into accounts like Deutsche Telekom, across your team, your customers, your board and investors, and your partners. It then drafts the ask, routes it through the right connector and tracks it to a booked meeting. Book a 15-minute walkthrough and see it run against your own target accounts.
Frequently asked questions
How do you become a supplier to Deutsche Telekom?
Register in Deutsche Telekom's own supplier portal, One.Source, and commit to the sustainability, compliance and anti-corruption requirements set out in its Supplier Code of Conduct, which applies to all new Deutsche Telekom AG suppliers. The company's own page states that it will then add you to its supplier database and will contact potential suppliers whose products or services interest it. Registration makes you findable. It does not create a requirement, and it is not a sales channel.
Who makes technology buying decisions at Deutsche Telekom?
Requirements originate inside a segment rather than centrally. Germany sits with Rodrigo Diehl, Europe with Dominique Leroy, T-Systems with Ferri Abolhassan, and the US shareholding and group development with Thorsten Langheim. Jan Hofmeyr becomes the Board of Management member for Product and Technology on 1 November 2026. Large categories covering network technology, devices, IT and service platforms are negotiated through BuyIn, the procurement joint venture Deutsche Telekom owns fifty-fifty with Orange.
Does selling to Deutsche Telekom win you T-Mobile US?
No. Deutsche Telekom holds a majority stake of roughly 52.8 percent in T-Mobile US, but T-Mobile US is listed on Nasdaq, has its own board and its own procurement organisation, and has been led by Srini Gopalan as chief executive since 1 November 2025. Tim Hoettges chairs that board, which is the formal link, but a group agreement signed in Bonn does not produce a purchase order in Bellevue.
How does German governance change an enterprise sale here?
Deutsche Telekom is a German stock corporation with a two-tier structure: a Board of Management runs the company and a twenty-member Supervisory Board oversees it, with ten of those seats held by employee representatives under co-determination. The deputy chair is a member of the national executive board of ver.di. Anything that changes how work is done in Germany therefore meets employee representation as a formal step. The German state is also a large shareholder, holding 14.22 percent directly and 14.37 percent through KfW as of 30 June 2026.
Is Deutsche Telekom a competitor as well as a customer?
Frequently all three at once: customer, competitor and channel. T-Systems sells cloud, digital and managed IT services to the same enterprises many software vendors target, and in 2026 Deutsche Telekom and NVIDIA launched an Industrial AI Cloud in Munich with an investment of around one billion euros. Decide before the first meeting whether you are selling to the group, selling through T-Systems or competing with it, because the room will otherwise assume the wrong one.
