Real increase in company value
Company valuations are often based solely on accounting data or static reports, which limits the perspective — especially in one-off situations like a business sale.
At Enterium, we combine strategic advisory with advanced controlling to uncover the real drivers of value. We identify areas that truly boost profitability and valuation. This approach increases investor appeal and leads to long-term improvements in performance and enterprise value.
Partnership beyond the industry standard
We don’t see transaction advisory as simply executing a piece of the process without a broader perspective or genuine ownership engagement.
At Enterium, we go beyond the typical playbook — acting as your external CFO or strategic advisor. We combine transactional, controlling, and strategic expertise to lead the entire process: from preparation and analysis to negotiations and post-deal support. We take full responsibility not just for the valuation, but for securing all key terms of the deal.
Choosing the best growth path
In many companies, transaction decisions are made too quickly — without fully exploring the alternatives or long-term implications.
Our approach is rooted in strategic analysis of the company’s situation. Together with the client, we evaluate all viable scenarios: selling the business, bringing in an investor, restructuring, or continuing organic growth. We empower our clients with the clarity and confidence they need to make smart, informed decisions about the future.
Transparent collaboration
Poorly prepared or mismanaged transactions often lead to hidden costs or inevitable failure — resulting in frustration and loss of trust.
At Enterium, transparency is a core value. We’re upfront about risks, costs, and challenges. We don’t sell dreams — we deliver on what we promise. Our clients gain a reliable partner they can count on, even during the toughest phases of the project.

Feedback from our trusted clients
Our close collaboration with Enterium helped us restructure the entire finance function – both in our Polish company and its U.S. subsidiary. We laid a strong foundation for dynamic growth through continued international expansion, with Enterium playing a key role as our strategic advisor.
The Enterium team supported us as a financial and transaction advisor during the preparation of DRUKARNIA PEGWAN Sp. z o.o. for a strategic partnership process. Their involvement covered analytical and controlling data preparation, implementation of reporting systems, financial modelling and valuation, as well as end-to-end advisory leading to a successful transaction closing. I recommend Enterium as a highly professional partner.
The Enterium team provided comprehensive support in designing and implementing an ESOP incentive program for our key managers. Their experience and understanding of both legal-financial aspects and the softer succession-related challenges enabled us to create a solution tailored to our company’s needs and organisational culture.
Excellent communication and a deep understanding of our needs shown by the Enterium project team — including their responsiveness beyond standard working hours — significantly contributed to the successful outcome of the share sale process for the owners.
Their level of commitment, knowledge, experience, and foresight matched that of well-known Warsaw-based advisors, while offering a much more competitive and, most importantly, flexible approach.
Thank you to the Enterium team for efficiently delivering all valuation projects for our portfolio companies — and especially for their flexibility in adapting to our timelines.
