Sorainen is perhaps best known for its expertise in handling pan-Baltic, high-value corporate transactions. M&A deals form a key area of instruction, however the team's workload includes advising on the corporate finance aspects relating to large-scale renewable energy projects and cross-border joint ventures. Toomas Prangli, Piret Jesse, Karin Madisson and Mirell Prosa are the quartet at the helm of the practice; Prosa is a key contact for start-up clients. Robin Teever is well versed in handling mandates from clients in the defence sector, and Triin Ploomipuu is a name to note for M&A transactions. Lauri Liivat left the firm in July 2025.
Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- The Sorainen CMA team is exceptionally well managed; they are on top of the market and industry aspects, and they communicate exceptionally well. The team is versatile with specialized professionals, all of whom have their particular and well-thought-out roles in the team. One feels that the client's issues are a priority, and attention to finding a fitting solution is prevalent, rather than just showing "how busy we are," which is, unfortunately, too often the case with most law firms.
- The collaboration can be described as a partnership, which includes joint worship with the lawyers to define the target and find the best pathways for achieving the goals.
- Karin Madisson with her exceptional knowledge and experience: Corporate Governance & Shareholder Relations, Private Equity and M&A Transactions, Employment Disputes and Executive Contracts, Succession and Family Law, ESG and Defence Industry Legal Support.
- Piret Jesse and Sandra Mikli both have outstanding capacity to work agilely and smartly, providing quick and straight to the point answers.
- When it is needed to solve a task, we can call on weekends or early morning and get forward quickly. I'd like to point out senior partner, Piret Jesse, and her team member, Robin Teeveer, who are fast communicators and exact and productive in their work.
- Their approach to client service, efficiency, and knowledge management is considered ahead of regional competitors. Sorainen’s team is known for its cross-border expertise, especially in the Baltics. They are innovative with AI tools and legal tech.
