The lawyers take the time to thoroughly analyse each situation, considering all angles and potential impacts on the business.

ECOVIS ProventusLaw stands out for its speed, ability to deeply understand the issues at hand and strong knowledge of the business environment. I value Loreta Andziulytė highly. She always puts her best effort into identifying the legal solutions that bring the greatest benefit to our business.

Strength: “The team is properly involved and ready to help.”

ECOVIS ProventusLaw’s expertise in data protection is particularly impressive’. The group has extensive experience in assisting start-ups, IT companies, and financial service providers with a range of TMT matters, and is well known for handling fintech work.

Inga Karulaitytė often assists with regulatory compliance issues, including internal audits and licensing applications. She also acts on loan facility agreements and capital restructurings. We appreciate the quick and accurate communication. The firm’s know-how allows us to get easy solutions.

The finance team at ECOVIS ProventusLaw is principally focused on financial regulatory and licensing-related projects. It is also well equipped to handle investment fund matters.

Ecovis ProventusLaw professionally provides services for regulatory requirements, procedures, policies, consultations.

The team has an excellent experience with fintech companies. They helped many companies obtain licenses from the regulator and in daily compliance and AML functions.

All services provided by ECOVIS were sophisticated and brought high-quality results.

What sets this team apart, in our view, is their remarkable proficiency in handling intricate technical scenarios. It’s quite rare to find legal professionals who not only understand the intricacies of the law but also possess a deep knowledge of technology and related matters.

Inga has top-notch knowledge about the fintech industry in Lithuania and generally. She has in-depth knowledge in anti-money laundering regulation, and makes good adjustments to the practical needs of the client.
