    Aider Polska’s first acquisition – the next stage of growth


    The past few months have been a period of intensive change for Aider Polska. Following its rebranding and joining the international Aider Group, the company has been consistently implementing its strategy of building a modern organisation providing comprehensive outsourcing services for businesses.


    The next important step on this journey is the integration of Ground Frost and Ground Frost Outsourcing into Aider Polska. This is the first acquisition carried out by Aider Polska and, at the same time, an investment that strengthens both the team’s expertise and the company’s presence in the Polish market.


    However, this is about much more than expanding the scale of our operations. The combination of the two organisations primarily means the ability to offer clients an even broader range of services, access to new areas of expertise and a larger team of experts supporting business growth.


    Why did Aider Polska and Ground Frost join forces? A shared vision and People First culture


    The financial services and BPO markets in Poland are currently undergoing a period of intensive consolidation. Digitalisation, regulatory changes (including KSeF) and growing business expectations mean that organisations combining scale with modern technology are gaining a competitive advantage. However, at Aider Polska, we know that people will always remain at the heart of every technology.


    The decision to combine the two organisations was not accidental. For years, both Aider Polska and Ground Frost have built their positions based on similar values – strong, partnership-based relationships with clients, high-quality services and the belief that people are the greatest asset of any organisation.


    As Rafał Michniewicz, Managing Partner at Aider Polska, emphasises, choosing Ground Frost as the first company to join the group was not accidental:


    For years, both our organisations have focused on building relationships based on trust and a partnership approach. The addition of the Ground Frost team is not only a natural extension of our expertise into areas such as transaction advisory and valuations, but above all a strengthening of our organisational culture. We invest in people who share our passion for creating modern outsourcing solutions.


    Wojciech Kryński, Founder and Managing Partner at Ground Frost, also points to the significant benefits of joining forces:


    Joining the Aider Group gives us the opportunity to take our services to a completely new level of scalability. We are combining our existing experience in advanced advisory and financial modelling with Aider Polska’s strong technological and organisational infrastructure. For our clients, this means access to a full spectrum of support under one roof.


    Łódź joins the Aider Polska map


    One of the most important outcomes of the acquisition is the expansion of Aider Polska’s operations, which now has a physical accounting office in Łódź.


    Until now, the company operated through offices in Warsaw and Katowice. By joining forces with Ground Frost, another location has been added to the Aider Polska map, allowing us to support businesses in central Poland even more effectively.


    The presence of a local team means easier contact with clients, a better understanding of the specific characteristics of the regional market and the opportunity to build long-term business relationships.


    At the same time, all Aider Polska services remain available remotely, enabling the company to serve clients throughout Poland as well as international businesses operating in the Polish market.

    Expanding our expertise: Transaction advisory, financial modelling and business valuations


    Modern accounting outsourcing is about much more than keeping the books or preparing tax returns. Today’s businesses need a partner who can support them in making key strategic decisions. By welcoming experts from Ground Frost’s Łódź accounting office to our organisation, we are significantly expanding our range of services to include transaction advisory.


    An increasing number of companies are planning acquisitions, seeking investors, restructuring or selling their businesses. Such processes require not only knowledge of finance and tax, but also experience in risk analysis and preparing a business for a transaction.


    From now on, our clients can rely on comprehensive support in areas such as:



    As a result, Aider Polska is becoming a partner not only for the day-to-day accounting needs of businesses, but also for the delivery of strategic business projects.


    What does this mean for current and future clients?


    The combination of Aider Polska and Ground Frost primarily brings tangible benefits to businesses.


    Clients gain:


    • access to more than 400 experts in accounting, HR and payroll, financial reporting and tax consulting,
    • comprehensive financial, tax, HR and payroll services,
    • support in M&A processes and transaction advisory,
    • new expertise in financial modelling and business valuations,
    • Aider Polska’s presence in Warsaw, Katowice and Łódź,
    • the support of the international Aider Group, operating across the Nordic countries and Poland.

    This is another step towards building an organisation that combines local market knowledge with international experience and a modern approach to supporting businesses.


    Aider Polska’s long-term strategy and consistent growth


    The addition of Ground Frost and Ground Frost Outsourcing is an important stage in Aider Polska’s development, but above all, it is an investment in people, expertise and even better client service.


    Expanding our operations to Łódź, developing transaction advisory services and growing our team of experts enable us to respond even more effectively to the needs of businesses – both those operating locally and international organisations developing their business in Poland.


    This is another step in implementing Aider Polska’s strategy, which aims to build a modern organisation that supports business growth through knowledge, technology and partnership-based relationships.
