About us

We are Abacus alpha: the community for business

Abacus alpha is an experienced and financially sound investment company. We think and act on a long-term basis, promote joint working structures and create synergies through cooperation and the targeted expansion of our portfolio.

This is how we have developed an agile business community, one that is constantly growing and open to offering participants new perspectives for the long term.

We invest in companies that operate in the areas of automation and digitisation, clean tech/green tech and the development of innovative materials and manufacturing processes. We also focus on companies that represent in our view a good fit with our business community and that offer promising opportunities. Central to this focus are technology-based activities, digitisation, Industry 4.0 and artificial intelligence – which also falls under the services and trade sector.

Minority and majority participation are possible.

Our history

Abacus alpha is an investment firm owned by a holding company with majority participation in a traditional exchange-listed industrial enterprise.

The initiation of Abacus alpha GmbH’s business operations in 2006 laid the foundations for a constantly growing business community. Cooperatively aligned to this community are traditional majority and minority shareholdings in established medium-sized companies with strong and often above-average market positioning and profitability in the industry. The community also includes promising start-ups and companies we ourselves have incorporated. Abacus alpha’s total portfolio currently comprises 18 investments. These companies form a unique community by networking and exchanging with one another, learning from one another and taking advantage of synergies.

    Start-up investment

    Abacus alpha invests in a start-up that develops technology for encrypted news transmission, working without intermediate data storage on servers. The new venture is unable to establish itself in the market, however.

    Technology trading for industrial users

    Taking over an activity from its sister company, Abacus alpha becomes co-founder and majority shareholder of Abacus Resale GmbH. The new establishment specialises in the purchase and sale, as well as the assessment and return, of pumps, engines and fittings for industrial use.

  • May and December 2016

    Systematically enhanced

    Abacus alpha expands its portfolio: from May 2016 with a participation in ASB Systembau Horst Babinsky GmbH.

  • February 2018

    Fascination takes the floor

    If the floor at an event becomes a monitor and provides visual experiences, ASB Rental Solutions GmbH is probably behind it. The company, a 100 per cent Abacus alpha holding, hires out ASB Systembau Horst Babinsky GmbH’s illuminated floors.

  • March 2019

    High tech, steam and interim management

    The minority shareholding in Swedish specialists ANS Applied Nano Surfaces Sweden AB also represents investments in new materials.

    Focus on company building

    With the spin-off of the company builder Abacus neo, we are underlining our ambition to develop ideas in the early stages into successful long-term companies.

  • December 2023

    Participation in communications agency

    Düsseldorf-based communications agency SMART PR GmbH, which specializes in online PR and social media relations, is now part of the Abacus alpha Group. The cooperation will strengthen the competitiveness of SMART PR and at the same time the expertise of the Abacus alpha Group in the areas of online communication and content creation.


Our aim is to develop a diversified, highly profitable, forward-looking and technology-based group of companies. The spectrum is complemented by services and trade. We therefore seek to maintain a balanced structure made up of new and established companies.
  • We do not buy in order to sell.

    We think and act on a long-term basis and an orientation towards the future. Our strategy involves

    buying and holding – maintaining companies on a long-term and sustainable basis, and

    buying and building – taking advantage of shared strengths for growth and expansion of the market position, and creating synergies within the business community

  • We value and respect the historical development and individuality of an enterprise and the people who work for it. We assume responsibility with a goal of helping the company achieve long-term success while respecting its values and its business culture. We promote the sustainability of lifetime achievements and the safeguarding of family interests.

  • We also invest capital. Our capital investments profit from our network in numerous ways. As a business community, we make it easier for international structures to be developed or expanded, for example. We promote knowledge transfer and enable enterprises to learn from each other. We also provide services and create synergies in the areas of human resources, controlling, IT or accounting. 

  • We help ideas find a market. If a business idea has genuine potential and if its realisation is a strategic benefit for our business community, then we turn it into reality - as a founder or partner in building the company. This is how we help ideas find their market. 

  • We provide a great deal of freedom. We are convinced that management’s individual responsibility, freedom and room to manoeuvre are important factors in a company’s success.
