The firm operates without proprietary technology platforms, relying instead on established legal practice management, document management, and case management systems. Its business model is built on professional services delivery: legal counsel is billed on hourly rates, fixed fees for specific matters, or project-based fees, with no publicly disclosed pricing. Distribution is direct and partner-led, with new clients acquired through the firm website, professional referrals, and earned media in legal publications; the firm explicitly does not use intermediaries or resellers. The firm has accumulated tier-1 recognition across major legal rankings including Chambers Europe, Legal 500 EMEA, IFLR1000, and Ukrainian legal publications, with consecutive top rankings in dispute resolution, real estate and construction, sports law, and tax.
Ilyashev & Partners' client base is diversified across large multinational enterprises (including Nestlé Ukraine & Moldova, Coca-Cola HBC, Mondelēz International), domestic corporates, and a growing segment of international NGOs and humanitarian organizations (AVSI Foundation, Ukrainian Red Cross Society, Terre des hommes, ESTDEV). The firm also serves private clients through asset protection, family capital structuring, and sanctions advisory. The firm is led by Managing Partner Mikhail Ilyashev and Senior Partner Roman Marchenko, both Honored Lawyers of Ukraine, and operates as an independent partnership with no external investors or parent company.
