We seek innovative solutions to technical challenges

For more than twenty years, we have been investing in companies facing special entrepreneurial challenges, such as first-time market entry, internationalisation, the development of new business fields or corporate succession. Our investment strategy focuses on companies that stand out due to their technological competence and market potential. In the case of companies that are established in the market and striving for a new strategic position, we usually only consider a majority investment, while in the case of young companies that are still in the start-up phase, we usually take minority stakes. We typically invest between 0.5 and 5.0 million Euros.

We have extensive experience in managing and advising larger medium-sized companies and have also have taken part in restructuring, reorganisation, divestments and acquisitions, as well as subsequent corporate integration. On this basis, we support companies in their strategic conception and on concrete implementation issues.

Investment Process

We have established the following steps in order to reach a well-founded and swift decision regarding the investment process.

Preliminary assessment

On the basis of basic information about the industry, business model, size and capital requirements, we clarify whether an investment in your company would generally fit our profile. A personal meeting then reveals whether there is a basis for a trusting and constructive cooperation between all persons involved.

Company analysis

You present your company and we examine it according to economic, financial, technical, organisational and personnel criteria. The aim is to jointly define the entrepreneurial challenges and to develop strategies for expanding competitive advantages and limiting risks.


Owners often evaluate their company differently than investors because the risks associated with the realisation of corporate planning are assessed differently. Open communication about the respective approach to valuation as well as a willingness to compromise help to overcome this hurdle.

Contract negotiation

Short decision-making processes and legal competence on our side facilitate contract negotiations. Conflict-prone issues should be identified and dealt with at an early stage in the negotiations. This regularly includes the question of when and how participation is to be terminated.


Immediately after conclusion of the contract, we transfer the funds and take over shares as agreed in the contract. While the management of the company remains solely in the hands of its managers, we participate in setting the strategic course on the basis of current reports and analyses. In doing so, we contribute to the entrepreneurial success with our experience and our network.


The time horizon for our investment is not subject to any fixed specifications. However, our investments are not destined for eternity. Therefore, it is also important to find a joint arrangement for a later exit. The primary objective is to provide the company with reliability and security for successful development in the future.

  1. The responsible party pursuant to Art. 4 (7) of the EU General Data Protection Regulation (GDPR) is:

  1. If we use commissioned service providers for individual functions of our offers or would like to use your data for advertising purposes, we will inform you in detail about the respective processes below. In doing so, we will also state the defined criteria for the storage period.

General information on the processing of data

  1. As a matter of principle, we collect and use personal data of our users only to the extent that this is necessary for the provision of a functional website as well as our contents and services. The collection and use of our users' personal data regularly takes place only with the user's consent. An exception applies in those cases in which it is not possible to obtain prior consent for actual reasons and the processing of the data is permitted by legal regulations. 
  1. Insofar as we obtain the consent of the data subject for processing operations of personal data, Art 6 (1) (a) GDPR serves as the legal basis. When processing personal data that is necessary for the performance of a contract to which the data subject is a party, Art. 6 (1) (b) GDPR serves as the legal basis. This also applies to processing operations that are necessary for the performance of pre-contractual measures. Insofar as the processing of personal data is necessary for the fulfilment of a legal obligation to which our company is subject, Art. 6 (1) (c) GDPR serves as the legal basis. In the event that vital interests of the data subject or another natural person make processing of personal data necessary, Art. 6 (1) (d) GDPR serves as the legal basis. If the processing of data is necessary to protect a legitimate interest of our company or a third party and the interests, fundamental rights and freedoms of the data subject do not outweigh the first-mentioned interest, Art. 6 (1) (f) GDPR serves as the legal basis for the processing of data.
  1. The personal data of the data subject will be deleted or blocked as soon as the purpose for storing it no longer applies. Storage may also take place if this has been provided for by the European or national legislator in Union regulations, laws or other provisions to which the controller is subject. Data will also be blocked or deleted if a storage period prescribed by the aforementioned standards expires, unless there is a need to continue storing the data for the conclusion or performance of a contract.
  1. Furthermore, we may pass on your personal data to third parties if participation in promotions, competitions, conclusion of contracts or similar services are offered by us together with partners. You will receive more detailed information on this when you provide your personal data or within in the description of the offer. If our service providers or partners are based in a country outside the European Economic Area (EEA), we will inform you about the consequences of this in the description of the offer.

Your rights

  1. You have the following rights with regard to your own personal data:
    1. Right of access
      You have the right to request confirmation as to whether data relating to you is being processed and to be informed of this data and to receive further information and a copy of the data in accordance with Art. 15 GDPR.
    2. Right to rectification
      According to Art. 16 GDPR, you have the right to request that data concerning you be completed or that inaccurate data concerning you be corrected.
    3. Right to deletion or right to restriction of processing
      In accordance with Art. 17 GDPR, you have the right to demand that data concerning you be deleted without delay, or alternatively, in accordance with Art. 18 GDPR, to demand restriction of the processing of the data.
    4. Right to transferability of data
      You have the right to request that the data relating to you that you have provided to us be received in accordance with Art. 20 GDPR and to request that it be transferred to other data controllers.
  1. You also have the right to complain to relevant data protection supervisory authorities about our processing of your personal data. For us, this is the Commissioner for Data Protection and Freedom of Information in North Rhine-Westphalia (ldi):https://www.ldi.nrw.de/ 

Objection or revocation against the processing of your data

  1. If you have given your consent to the processing of your data, you may revoke this consent at any time in accordance with Art. 7 (3) GDPR. Such a revocation affects the permissibility of the processing of your personal data after you have expressed it to us.
  1. Insofar as we base the processing of your personal data on the balance of interests, you may object to the processing. This is the case if the processing is not necessary, in particular, for the performance of a contract with you, which is shown by us in each case in the following description of the functions. When exercising such an objection, we ask you to explain the reasons why we should not process your personal data as we have done. In the event of your justified objection, we will review the situation and either discontinue or adapt the data processing or show you our compelling legitimate grounds on the basis of which we will continue the processing.

Of course, you can object to the processing of your personal data for advertising and data analysis purposes at any time. You can inform us of your advertising objection using the following contact details: HCS Beteiligungsgesellschaft mbH, 

Bockenheimer Landstraße 2-4, D-60306 Frankfurt am Main, Phone.: + 49 (0) 69 264 846 280, Fax: + 49 (0) 69 264 846 281, Email: info@hcs-beteiligungen.de.   

Deletion of data

The data processed by us will be deleted or restricted in its processing in accordance with Articles 17 and 18 GDPR. Unless expressly stated within the scope of this data protection declaration, the data stored by us will be deleted as soon as it is no longer required for its intended purpose and the deletion does not conflict with any statutory retention obligations. If the data is not deleted because it is required for other and legally permissible purposes, its processing will be restricted. I.e., the data is blocked and not processed for other purposes. This applies, for example, to data that must be retained for reasons of commercial or tax law. According to legal requirements in Germany, data is stored in particular for 6 years in accordance with Art. 257 para. 1 HGB (commercial books, inventories, opening balances, annual financial statements, commercial letters, accounting vouchers, etc.) and for 10 years in accordance with Art. 147 para. 1 AO (books, records, management reports, accounting vouchers, commercial and business letters, documents relevant for taxation, etc.).

Transfer of data to third countries

If we process data in a third country (i.e., outside the European Union (EU) or the European Economic Area (EEA)) or if this is done in the context of using third-party services or disclosing or transferring data to third parties, this is only done in order to fulfil our (pre-)contractual obligations, on the basis of your consent, due to a legal obligation or on the basis of our legitimate interests. Subject to legal or contractual permissions, we only process or allow the processing of data in a third country if the special requirements of Art. 44 et seq. GDPR are met. This means, for example, that the processing is carried out on the basis of special guarantees, such as the officially recognised determination of a level of data protection corresponding to the EU or compliance with officially recognised special contractual obligations (so-called "standard contractual clauses").

Data collection on our website (Logfiles)

  1. In the case of merely informative use of the website, i.e., if you do not register or otherwise transmit information to us, we only collect the personal data that your browser transmits to our server. If you wish to view our website, we collect the following data, which is technically necessary for us to display our website to you and to ensure its stability and security (legal basis is Art. 6 para. 1 p. 1 lit. f GDPR):
  1. IP-Address,
  2. Date and time of the request,
  3. Time zone difference to Greenwich Mean Time (GMT),
  4. Content of the request (specific page),
  5. Access status/HTTP status code,
  6. Amount of data transferred in each case,
  7. Website from which the request came,
  8. Browser,
  9. Operating system and its interface,
  10. Language and version of the browser software.
  1. This data is also stored in the log files of our system. This data is not stored together with other personal data of the user. The legal basis for the temporary storage of the data and the log files is Art. 6 para. 1 lit. f GDPR. The storage in log files is done to ensure the functionality of the website. In addition, we use the data to optimise the website and to ensure the security of our information technology systems. An evaluation of the data for marketing purposes does not take place in this context. The anonymous data of the server log files are stored separately from any personal data provided by a data subject.
  1. The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended. The collection of data for the provision of the website and the storage of the data in log files is absolutely necessary for the operation of the website. Consequently, there is no possibility for the user to object. 

Usage of Cookies

  1. In addition to the aforementioned data, cookies are stored on your computer when you use our website. Cookies are text files that are stored in the internet browser or by the internet browser on the user's computer system. Cookies cannot execute programs or transfer viruses to your computer. They are used to make the website on the whole more user-friendly and effective. Cookies enable us to recognise the users of our website. By means of a cookie, the information and offers on our website can be optimised to suit the user. The purpose of this recognition is to make it easier for users to use our website. For example, the user of a website that uses cookies does not have to re-enter their access data each time they visit the website, because this is done by the website and the cookie stored on the user's computer system.
  1. Temporary cookies or "session cookies" or "transient cookies" are cookies that are deleted after a user leaves an online offer and closes their browser. The content of a shopping basket in an online shop or a login status, for example, can be stored in such a cookie. Cookies that remain stored even after the browser is closed are referred to as "permanent" or "persistent". For example, this allows the login status to be saved when users visit the site after several days.
  1. In addition to so-called "first-party cookies", which are set by us as the data controller, "third-party cookies" are also used, which are offered by third-party providers. If "third-party cookies" are set, we will inform you about this within the respective data protection information of the online offers as well as about the cooperation with external service providers.
  1. The legal basis for the processing of personal data using "first-party cookies" is Art. 6 para. 1 lit. f GDPR and for "third-party cookies" Art. 6 para. 1 lit. a GDPR.
