Testimonials
Collated independently by Legal 500 research team.
- Krzysztof Marczuk - a very experienced and knowledgeable lawyer with the ability to solve uncommon problems in a creative way. Honest and highly reliable. Magdalena Marczuk - an experienced and very diligent lawyer with high attention to the most important issues. Jakub Rowicki - very hard-working, always available, and able to prepare documents in an extremely short time. Michał Wieliński - highly reliable, well-versed lawyer with experience in both capital markets as well as M&A.
- The key characteristics that set GESSEL apart are: 1) outstanding knowledge of Polish Capital Market regulations, including specific local requirements of the Polish Financial Supervision Authority and the Polish Central Securities Depository; 2) orientation toward business goals and nimbleness – particularly valuable when applied in the case of small to mid-size transactions that often require the ability to quickly adjust to changing conditions of such projects; 3) very high availability – I’ve never had any problems reaching GESSEL’s project team members. With respect to innovations, GESSEL is usually among the first law firms to be able to comment on changes in the legal landscape (e.g. when the Listing Act was introduced, GESSEL's material on this matter was one of the first and most comprehensive reviews circulating on the market).
- ‘As a responsive, pro-client partner, Krzysztof Marczuk leverages extensive experience and sharp commercial instincts to propose innovative fixes to challenges arising during proceedings.'
- ‘The team combines strong competence, deep experience and pragmatism with a genuinely collaborative, easy-to-work-with approach. Well-recognised domestically. I can highlight the team’s responsiveness and quality - precise, well-considered answers delivered quickly, backed by solid know-how and reliable execution; a highly experienced group that delivers solutions.’
- ‘In my view, Gessel Attorney at Law is a distinguished firm that excels in handling complex, high-value transactions of strategic importance to mid- and large-cap enterprises. Their many years of experience in M&A, private equity, venture capital, and public capital markets, combined with deep knowledge of market practices and strong relationships across industries and financial institutions, enable them to provide comprehensive legal advice that fully reflects current market and economic trends.’
- ‘In my experience, Krzysztof Marczuk is an exceptional team leader who combines deep legal knowledge with practical business acumen. Although he focuses mainly on ECM and DCM transactions, his background in criminal, civil, and bankruptcy proceedings gives him a rare, comprehensive perspective.'
