K3 ADVISORY
GROUP
Founded in 1998, KBS Corporate has been instrumental in firmly establishing K3 Advisory Group as one of Europe’s leading mid-market business sales advisers.
Every year since 2022 we have been ranked among the top three by the London Stock Exchange Group (LSEG) for deal volume across the European continent, reflecting our cross-border capability and the confidence of clients operating across multiple jurisdictions. We are also ranked in the top five globally.
K3 Advisory Group has experienced a monumental rise, with KBS Corporate proud to have contributed substantially to the ongoing success.
K3 was floated on the London Stock Exchange’s AIM in 2017, helping us to develop from a business sales advisory into a fast-growing professional services group.
In 2023, the Group was acquired by Sun European Partners, a leading private investment firm focused on defensible businesses in growing markets with an expanding professional services portfolio.
K3 Advisory Group is an international professional services group providing specialist advice across:
- Business Sales and Deal advisory
- Business Services, including specialist tax
- Technology Solutions
- Restructuring Advisory
- Wealth Management
The group supports owners, leaders, investors and their professional advisers when decisions carry real weight. We bring together specialist expertise, commercial judgement and coordinated execution to protect what has been built and strengthen what comes next.
Our role is not simply to advise on a transaction or technical issue. It is to ensure decisions are commercially sound, structurally robust and sustainable over time.
With more than 1,200 employed professionals, 25 offices and an international presence, K3 Advisory Group is built for moments that matter and structured for sustained momentum.
