Before the move, Polak spent a year with LSW, which she joined in July 2023 (as reported by CEE Legal Matters on July 10, 2023). Earlier, she spent four years with B2RLaw as a Partner, from 2019 to 2023. Before that, she spent two and a half years as a Senior Associate with the former Maruta Wachta, between 2016 and 2019, and another two and a half with Kochanski Zieba & Partners, also as a Senior Associate, between 2014 and 2016.

The legal and compliance team I’ve joined focuses on client contracts, transactions, and regulatory aspects related to AI, data protection, and cybersecurity. We strive to help the company achieve its business objectives. What is especially exciting for me is that our team includes legal and compliance professionals from the US, the Netherlands, and Poland. We work on international projects across many jurisdictions, enhancing innovative technologies.”
