MediGate GmbH
MediGate GmbH is a German limited liability company (Gesellschaft mit beschränkter Haftung) entered in the commercial register at the Amtsgericht Hamburg under HRB 89986. Its registered office is Martinistraße 52, 20246 Hamburg, and its registry status is Active. The company’s own legal notice states the same register entry and gives the VAT identification number DE234021689 and the Wirtschafts-Identifikationsnummer DE234021689-00001.
MediGate GmbH provides research-administration and research-commercialisation services to scientists at the Universitätsklinikum Hamburg-Eppendorf (UKE). It organises that work in four departments: grant-application support (Antragsunterstützung), costing and controlling of clinical trials (Kalkulation und Controlling Klinischer Studien), contract management for third-party research funding (Vertragsmanagement Drittmittel), and technology transfer. The company states that its purpose is to strengthen research at the UKE both by increasing third-party funding income and by protecting and commercialising intellectual property generated there.
The technology-transfer activity covers advice to inventors and a first point of contact for spin-out founders, assessment of inventions for protectability and market potential, filing of industrial property rights together with specialist patent attorneys, technology-specific market and competitor analysis, active IP portfolio management, structuring of collaborative projects with industry, negotiation of exploitation and licence agreements, and the commercialisation of research reagents and analytical services. Its counterparties are therefore national and EU research funders and life-science companies. Operations are concentrated in Hamburg: the postal address is in building CPW 1 at Martinistraße 52, and staff are located at Christoph-Probst-Weg 1, 20251 Hamburg.
Two identity fields in the information card above should not be read literally. The incorporation date shown as 1 January 2010 is a year-only placeholder emitted by the data feed, and the year itself is wrong: the company states it was founded in 2004, the earliest register-linked managing-director appointment on this record is dated 9 March 2004, and annual accounts have been published for financial years from 2006 onwards. The legal form shown as "Private limited company (Ltd.)" is a generic feed label; the entity is a German GmbH.
No revenue or employee figure could be verified for MediGate GmbH itself. Annual accounts for financial years 2006 to 2021 are published in the Bundesanzeiger, but the accounting documents are access-controlled and could not be opened, and filings for 2022 onwards have moved to the Unternehmensregister. This profile covers only the entity registered under HRB 89986 Hamburg; businesses trading under the MediGate name in other jurisdictions, including the medical-device security company of that name, are separate legal entities and nothing here relates to them.

Shareholders
1
Shareholders of MediGate GmbH
One shareholder is disclosed for MediGate GmbH, and the record is complete rather than truncated: the stored shareholder list holds one row against a reported total of one. The sole shareholder is UKE Business Services GmbH & Co. KG, a German limited partnership, holding 100% of the share capital directly. The holding was verified at 4 September 2026 in the underlying registry data.
The 100% figure does not rest on the provider data alone. The Freie und Hansestadt Hamburg publishes a statutory holdings report (Beteiligungsbericht) covering the companies in which the city-state has a direct or indirect interest. Its extract for the Universitätsklinikum Hamburg-Eppendorf group, as at 31 December 2024, lists MediGate GmbH as a second-tier holding (Enkelunternehmen) whose shareholder is UKE Business Services GmbH & Co. KG at 100.00%, and records no other shareholder above 25%. Two independent sources therefore agree, and there is no minority interest to report.
The stored record describes the holding as a single ordinary share with a nominal value of €25,000 — the statutory minimum share capital for a German GmbH. That figure comes from the data feed and was not confirmed against a filed shareholder list (Gesellschafterliste), so it should be treated as indicative of the capital structure rather than as a verified amount.
Ultimate beneficial ownership
No natural person is identifiable as an ultimate beneficial owner of MediGate GmbH through the ownership chain, and none is claimed here.
The chain is complete and terminates in a public authority. MediGate GmbH is held 100% by UKE Business Services GmbH & Co. KG, which is held 100% by the Universitätsklinikum Hamburg-Eppendorf, a Körperschaft des öffentlichen Rechts. The Beteiligungsbericht records that the Freie und Hansestadt Hamburg holds 100% of the UKE and states that the city-state’s fully diluted interest ("durchgerechnet") is 100.00%. Multiplying through the chain gives a calculated effective ownership of 100% held by the Freie und Hansestadt Hamburg as at 31 December 2024. A federal state is not a natural person, so no beneficial owner in the ordinary ownership sense exists at the end of this chain.
Germany’s Transparenzregister, which would record any notional beneficial owner (fiktiver wirtschaftlich Berechtigter) recorded for the company, has not been open to general public inspection since access was restricted in 2023, so no entry could be checked. Nothing in this section should be read as a statement that the company has no registered beneficial owner.
Data availability
Full for the direct shareholder: the sole shareholder, its legal form and its percentage are available and are confirmed by an official state publication, and the whole ownership chain up to the ultimate public owner is traceable. Beneficial-ownership data is Restricted — the German Transparenzregister exists but is not publicly accessible, and the filed Gesellschafterliste at the Handelsregister was not retrieved, so the nominal share capital shown above remains unconfirmed.

Officers
3
Directors and officers of MediGate GmbH
Three officer records are disclosed for MediGate GmbH and the list is complete rather than truncated: three rows are stored against a reported total of three. One officer is active and two have left. Every record carries the same legal role, Geschäftsführer (managing director) — the office that represents a German GmbH. No supervisory board member, Prokurist or other authorised signatory appears on the record.
The active officer is Silke Schrum, appointed managing director on 26 April 2019. That appointment is independently confirmed by the company’s own legal notice, which names Dr. rer. nat. Silke Schrum as Geschäftsführerin and was last amended on 30 December 2024, and by the company’s team page.
The two former managing directors are Ralf Krappa, appointed 8 March 2005 and ended 20 January 2021, and Kathrin Sabine Adlkofer, appointed 9 March 2004 and ended 6 October 2005. The dates show two managing directors in office together between April 2019 and January 2021, which is a normal handover pattern for a GmbH.
Two points of caution. First, the Adlkofer appointment of 9 March 2004 predates the incorporation date of 1 January 2010 carried elsewhere on this record — the officer dates are the more reliable of the two, and the company states it was founded in 2004. Second, the Freie und Hansestadt Hamburg’s own science-ministry page for MediGate GmbH still lists Dr. Ralf Krappa as Geschäftsführer, more than five years after his appointment ended; that page is out of date and should not be relied on for current management.
Recent officer changes
| Change | Person | Role | Effective date | Source |
|---|---|---|---|---|
| Appointment | Silke Schrum | Geschäftsführerin (managing director) | 26 April 2019 | Stored Handelsregister-sourced officer record; confirmed by the company’s Impressum |
| Departure | Ralf Krappa | Geschäftsführer (managing director) | 20 January 2021 | Stored Handelsregister-sourced officer record |
No officer change has been recorded since 20 January 2021.
Data availability
Current and historical officers are available, with legal roles and exact appointment and termination dates, and the current managing director is corroborated by the company’s own published legal notice. Nationality is Not disclosed: the German Handelsregister does not publish the nationality of a managing director, no filing consulted records it, and it must not be inferred from a name or an address — the country code "DE" held against each officer row relates to a correspondence address, not to citizenship or residence. No residential address, occupation or country of residence is disclosed for any officer, and no street address is recorded on any of the three rows. Dates of birth are held in the underlying data but are not published here.
The officer data on this record carries no capture date of its own; the record as a whole was last synchronised on 8 September 2026. Stored officer lists in this dataset are frequently stale, so an appointment should be re-checked against a current Handelsregister extract before it is relied on.

Group Structure
Group structure of MediGate GmbH
MediGate GmbH is not independent. It is a wholly owned member of the Universitätsklinikum Hamburg-Eppendorf group, which is itself wholly owned by the Freie und Hansestadt Hamburg. The chain is short, fully documented and confirmed by an official state publication rather than by the data feed alone.
Its immediate parent is UKE Business Services GmbH & Co. KG, which holds 100% of the share capital. Above that sits the Universitätsklinikum Hamburg-Eppendorf, a Körperschaft des öffentlichen Rechts constituted under the Hamburg UKE-Gesetz, holding 100% of the partnership. The ultimate controlling entity is the Freie und Hansestadt Hamburg, which holds 100% of the UKE and whose fully diluted interest in the group is recorded as 100.00%. The city-state’s holdings report classifies MediGate GmbH as an Enkelunternehmen — a second-tier holding — and records no other shareholder above 25%.
MediGate GmbH has no subsidiaries. It has two verified sister companies, both wholly owned by the same immediate parent: Martini-Klinik am UKE GmbH and ForEx Gutachten GmbH. The UKE’s own subsidiary index groups MediGate GmbH and ForEx Gutachten GmbH together as its "wissenschaftliche Tochtergesellschaften" (scientific subsidiaries). Every entity in the verified structure is German and all are registered in Hamburg; the group has no cross-border element on this record. The structural information is stated as at 31 December 2024, the position date of the holdings report.
Verified corporate relationships
| Entity | Country | Registration number | Relationship | Ownership | Status | Information date |
|---|---|---|---|---|---|---|
| UKE Business Services GmbH & Co. KG | DE | HRA 114150, Amtsgericht Hamburg (from stored register data; not independently confirmed) | Immediate parent | 100.00% of share capital | Active | 31 Dec 2024 |
| Universitätsklinikum Hamburg-Eppendorf (KöR) | DE | Körperschaft des öffentlichen Rechts — not a Handelsregister entity | Indirect parent, via UKE Business Services GmbH & Co. KG | 100.00% of the immediate parent | Active | 31 Dec 2024 |
| Freie und Hansestadt Hamburg | DE | Public authority — no company registration number | Ultimate controlling entity | 100.00% of the UKE; 100.00% fully diluted through the chain | n/a | 31 Dec 2024 |
| Martini-Klinik am UKE GmbH | DE | HRB 93315, Amtsgericht Hamburg (confirmed from that company’s own legal notice) | Sister company | 100.00% held by the same immediate parent | Active | 31 Dec 2024 |
| ForEx Gutachten GmbH | DE | HRB 149396, Amtsgericht Hamburg (from stored register data; not independently confirmed) | Sister company | 100.00% held by the same immediate parent | Active | 31 Dec 2024 |
No acquisition, disposal, merger or reorganisation affecting MediGate GmbH could be verified from the sources consulted, so no list of recent structural changes is given. That is an absence of evidence, not evidence that the structure has been unchanged.
Data availability
Full for the upward chain: the immediate parent, every intermediate holder, the ultimate controlling entity and the ownership percentages at each step are published, and the percentages agree between the stored register data and the city-state’s statutory holdings report. Coverage of sister companies is Partial — the relationships are verified but two of the register numbers above come from stored data that could not be checked against a primary filing, and no filed accounts for MediGate GmbH could be opened, so no figure is available for any entity at MediGate’s own level.
Three defects in the stored corporate-linkage data should be recorded. First, the stored tree is rooted at a node called "Bundesland Hamburg" placed above a separate node for the "Freie und Hansestadt Hamburg", as though one owned the other; these are the same city-state under two names, and the duplication is an artefact of the feed. Second, the tree contains 330 nodes across eight levels and sweeps in a large number of Hamburg municipal companies — city marketing, tourism, economic-development and property vehicles among them — that stand in no ownership relationship to MediGate GmbH at all. They share a public shareholder, which is not the same thing as belonging to the same corporate group, and they should not be read as related companies. Third, the tree carries a public authority as the root of a corporate structure; in this particular case the public ownership chain is genuine and is confirmed by the holdings report, but the four entities listed above are the only ones in MediGate GmbH’s actual ownership line.
One favourable check: the identifiers in the stored tree are encoded as the Hamburg register court code 20355 followed by the register section and number, so "DE 20355B89986" resolves to HRB 89986 Hamburg, which matches both the company’s own legal notice and the registration number on this record. The same encoding produced HRB 93315 for Martini-Klinik am UKE GmbH, which that company’s legal notice confirms.

Frequently Asked Questions
What does MediGate GmbH do?
MediGate GmbH is the research-transfer and research-administration company of the Universitätsklinikum Hamburg-Eppendorf (UKE), registered at the Amtsgericht Hamburg under HRB 89986. It supports UKE scientists in four areas: grant-application support, costing and controlling of clinical trials, contract management for third-party research funding, and technology transfer. The technology-transfer work covers advising inventors and prospective spin-out founders, assessing inventions for protectability and market potential, filing industrial property rights with specialist patent attorneys, market and competitor analysis, IP portfolio management, structuring collaborations with industry, negotiating exploitation and licence agreements, and commercialising research reagents and analytical services. The company states it was founded in 2004. Note that the incorporation date of 1 January 2010 shown on this page is a year-only placeholder from the data feed and the year is contradicted by the company's own statement, by a managing-director appointment dated 9 March 2004, and by annual accounts filed for financial years from 2006 onwards. The legal form label "Private limited company (Ltd.)" is likewise a generic feed value; MediGate GmbH is a German GmbH.
Who owns MediGate GmbH?
One shareholder is disclosed and the record is complete, not truncated. UKE Business Services GmbH & Co. KG, a German limited partnership, holds 100% of the share capital of MediGate GmbH directly. The holding was verified at 4 September 2026 in the registry data and is independently confirmed by the Freie und Hansestadt Hamburg's statutory holdings report (Beteiligungsbericht) as at 31 December 2024, which lists MediGate GmbH as a second-tier holding of UKE Business Services GmbH & Co. KG at 100.00% and records no other shareholder above 25%. There is no minority shareholder.
Who is MediGate GmbH's UBO (Ultimate Beneficial Owner)?
No natural person is identifiable as an ultimate beneficial owner of MediGate GmbH, and none is claimed. The ownership chain is complete and ends in a public authority: MediGate GmbH is 100% held by UKE Business Services GmbH & Co. KG, which is 100% held by the Universitätsklinikum Hamburg-Eppendorf (a Körperschaft des öffentlichen Rechts), which is in turn 100% held by the Freie und Hansestadt Hamburg. Multiplying through the chain gives a calculated effective ownership of 100% held by the city-state of Hamburg as at 31 December 2024. A federal state is not a natural person, so the chain produces no beneficial owner in the ordinary ownership sense. Germany's Transparenzregister, which would record any notional beneficial owner (fiktiver wirtschaftlich Berechtigter) entered for the company, has not been open to public inspection since access was restricted in 2023, so no entry could be checked. This is not a statement that the company has no registered beneficial owner.
What is MediGate GmbH's company registration number?
MediGate GmbH's registration number is HRB 89986 Hamburg, filed with Handelsregister (Commercial Register) in Germany. Its current status on the register is active.
Is MediGate GmbH still an active company?
MediGate GmbH's status on Handelsregister (Commercial Register) is listed as active.
What is MediGate GmbH's registered address?
The registered address on file for MediGate GmbH is Hamburg, Germany.
What is MediGate GmbH's revenue?
No revenue or employee figure for MediGate GmbH could be verified. The company files annual accounts in Germany — the Bundesanzeiger lists 16 publications for financial years 2006 through 2021, the latest published on 10 February 2023 — but the accounting documents are access-controlled and could not be opened, and filings from financial year 2022 onwards have moved to the Unternehmensregister, which is not freely retrievable either. The Freie und Hansestadt Hamburg's holdings report gives balance-sheet figures for the Universitätsklinikum Hamburg-Eppendorf group, but those are group figures for a large university hospital and must not be read as MediGate GmbH's own revenue, balance sheet or headcount.
Is MediGate GmbH listed on a stock exchange?
No. MediGate GmbH is a private German limited liability company (GmbH) and is not listed on any stock exchange. It has no ticker symbol and no traded securities. Its entire share capital is held by a single corporate shareholder, so there is no free float.
Who are the officers/directors of MediGate GmbH?
Three officer records are disclosed and the list is complete, not truncated: one active and two departed, all holding the role of Geschäftsführer (managing director). The active officer is Silke Schrum, appointed managing director on 26 April 2019 — confirmed by the company's own legal notice, which names Dr. rer. nat. Silke Schrum as Geschäftsführerin and was last amended on 30 December 2024. The former managing directors are Ralf Krappa (8 March 2005 to 20 January 2021) and Kathrin Sabine Adlkofer (9 March 2004 to 6 October 2005). No supervisory board member or Prokurist appears on the record. Nationality is not disclosed: the German Handelsregister does not publish it and no filing consulted records it. Note that the Freie und Hansestadt Hamburg's science-ministry page for the company still names Dr. Ralf Krappa as managing director and is out of date.
Does MediGate GmbH have a parent company or subsidiaries?
MediGate GmbH is not independent. Its immediate parent is UKE Business Services GmbH & Co. KG (100% of the share capital); above that sits the Universitätsklinikum Hamburg-Eppendorf, a Körperschaft des öffentlichen Rechts, holding 100% of the partnership; and the ultimate controlling entity is the Freie und Hansestadt Hamburg, holding 100% of the UKE. The city-state's holdings report as at 31 December 2024 classifies MediGate GmbH as an Enkelunternehmen, a second-tier holding. MediGate GmbH has no subsidiaries and two verified sister companies under the same immediate parent: Martini-Klinik am UKE GmbH (HRB 93315 Hamburg) and ForEx Gutachten GmbH. Every entity in the verified structure is German and registered in Hamburg. Caution on the stored group tree: it holds 330 nodes across eight levels and pulls in many Hamburg municipal companies — city marketing, tourism, economic-development and property vehicles — that share the same public shareholder but stand in no ownership relationship to MediGate GmbH. It also duplicates the city-state as two separate nodes, "Bundesland Hamburg" above "Freie und Hansestadt Hamburg".
Can Zavia monitor changes to MediGate GmbH's ownership over time?
This profile reflects a point-in-time snapshot from Handelsregister (Commercial Register). Zavia's monitoring API can track changes to MediGate GmbH's registered shareholders, officers, and group structure going forward, flagging updates as they're filed rather than requiring a manual recheck.
Can I access MediGate GmbH's data through an API?
Yes. Zavia's API connects directly to official government ownership registries across 195 countries and territories, including Germany, so records like MediGate GmbH's registration, shareholder, UBO, and group-structure data can be queried programmatically instead of viewed one page at a time.
Where does this company information come from, and how current is it?
This record is sourced directly from Handelsregister (Commercial Register) and was last synced on 8 September 2026.
