Companies in transition situations (from individual issues to a full-blown (pre-insolvency) crisis situation) need more than classic consulting – they need leaders who take action. Our CFO Services combine operational capability with strategic foresight: Whether as interim managing director, commercial manager, or Chief Restructuring Officer – we take responsibility where it is needed most urgently.
As part of horizon-re, our interim managers and CFO experts work hand in hand with the legal and business teams of the firm. This creates what forms the core of horizon-re: interdisciplinary consulting from a single source – proven in practice, solution-oriented, and always in the interest of the company.
We do not just present concepts, we also implement them. Our CFO Services mean: immediate operational capability, measurable results, and a team that speaks the language of all stakeholders – from management to banks to works councils and courts. All of this from the perspective of and together with the entrepreneur/shareholder.
A mandate always makes sense when commercial leadership competence is needed but cannot or should not be permanently maintained within the company, whether to bridge a vacancy, during a restructuring phase, or to prepare a strategic transaction. Our experience shows: the earlier we are involved, the greater the scope for action. Those who wait until liquidity becomes critical lose valuable options.
Classic agencies mediate individuals. We bring an interdisciplinary team: The operational CFO works closely with our lawyers and tax advisors from day one without interface losses, without parallel fee structures. Especially in complex situations, restructuring, distressed M&A, compliance issues, this integration is the decisive difference.
Within a few days. Our approach is designed for rapid onboarding: We immediately analyze the commercial situation, secure day-to-day business, and simultaneously implement initial structural measures. In acute crisis situations, such as impending insolvency, we begin with immediate liquidity securing measures even before a complete restructuring plan is in place.
Our mandates typically operate within the German mid-sized sector — from high-growth startups to established companies with several hundred employees. Industry focuses include mechanical engineering, the food industry, automotive, FMCG, and medical technology — but the core of our work, commercial management in times of change, is applicable across industries.
We see ourselves as an extension of the entrepreneur and management — not as an external control body. Our CFO mandates are explicitly designed from the shareholder's perspective: We speak the language of all stakeholders, from employees to banks to works councils and courts, and ensure that management retains full decision-making authority at every stage.
PE investors regularly face the same challenge in portfolio companies: The operational value creation plan is in place, but the commercial management structure within the company does not support it. horizon-re closes exactly this gap.
We take on CFO or CRO mandates in portfolio companies and deliver what PE firms need from day one: reliable reporting, clean liquidity management, and a financial structure that supports investor and bank discussions. At the same time, we bring the legal and tax expertise required immediately in distressed situations, add-on transactions, or exit preparations — without the investor having to coordinate multiple mandates simultaneously.
Our service offering for PE portfolio companies includes in particular:
We think like an investor, act like an entrepreneur — and deliver the substance that supports a process.
