COO of Sorainen

Diverse expertise, one business services system

Sorainen’s offices operate together as a single ecosystem under a single ISO 9001-certified quality management system. We use cutting-edge technology to share our experience and know-how between our offices, teams and sector groups. When our lawyers are confronted with an issue they can immediately draw on the vast experience Sorainen holds across all our jurisdictions, meaning they don’t have to spend so much time on research and can focus more on creating legal solutions that are just right for the client’s needs.

Sorainen employs modern legal technologies & AI:

Green Meadow Document Drafter – a document automation tool

Luminance, a form of artificial intelligence technology which streamlines M&A due diligence processes

xLaw, a knowledge management system helping lawyers enhance efficiency

Doing good as lawyers and living right

At Sorainen, we are committed to making the world a better place and supporting initiatives that we believe in. Our sustainability strategy is built on three pillars: doing good with our legal work, supporting charities and living right.

Legal work. As a law firm, we can make the largest impact by using our knowledge of law, so we:

  • help and educate students
  • work pro bono
  • advise on drafting better legislation
  • serve on boards and organise in NGOs
  • speak up on legal issues in public
  • develop new sustainable legal areas
  • have sustainable client acceptance policies

Most of our pro bono work is done in the framework of the Shared Mission programme. This programme was launched in 2020 to support a faster recovery of our region from the health and economic crisis caused by the COVID-19 pandemic. EUR 100,000 worth of support was distributed to over 20 organisations, with more than 40 lawyers working on the cases. The programme’s success made us certain that we need to continue with the programme.

Supporting charities. Every year, we take part in charitable activities.

What is really great, our people are individually very active in charitable causes – as founders, board members and supporters of NGOs, and volunteers for good causes. As a team, we are happy to join in when our colleagues reach out.

Living right. We adhere to certain principles.

  • Saving environment. We work for increasingly sustainable offices where sorting trash, avoiding plastic and using energy-saving equipment is a rule.
  • Respecting all people. We believe that all people were created equal, and we show this with our actions and HR policies.

UN Sustainability goals close to our heart

Like many organisations, we have also selected the UN sustainability goals that are close to our heart and resonate with our daily activities.

  • Endure healthy lives and promote well-being
  • Ensure inclusive and equitable quality education and promote lifelong learning opportunities
  • Build resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation
  • Make cities and human settlements inclusive, safe resilient and sustainable
  • Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions
