WTS

What WTS does

WTS is a Germany-headquartered global tax and financial advisory firm, founded in 2000 and reporting revenues exceeding €250 million from its German tax and financial advisory practice. The firm delivers tax advisory (corporate, international, transfer pricing, M&A tax, tax controversy), financial advisory (deal advisory, IPO support, restructuring, valuation), legal services, and tax technology services to listed companies, large private businesses, and growth-oriented clients through a senior-partner-led B2B engagement model. Its network spans more than 100 countries via WTS Global, with owned offices across major German cities plus regional entities in the UK (WTS UK, WTS Hansuke), the US (FLSV, GTM, VALENTIAM), and other markets, positioning WTS as the leading independent non-audit tax practice. In March 2026, WTS secured a €500 million private equity commitment from EQT Partners to fund an aggressive European and UK expansion under new CEO Jeff Soar (former EY UK MD), targeting ~100 UK partners within five years.

WTS's central technology is plAIground, an AI operating system for tax and finance developed through a WTS PSP AI joint venture with PSP Munich. The platform provides dialogue-based document interaction, knowledge retrieval from curated tax databases (Otto Schmidt Verlag, Tax Academy), a Knowledge Twin for organizational knowledge distribution, a Widget Creator for prompt-built applications, and pre-configured AI assistants (Daily, Personal, Upskilling, My Assistants) that allow tax and finance teams to automate routine tasks without programming knowledge. The firm complements the platform with an AI Campus training program for sustainable adoption, plus digital tax tools (WTS Compliance Manager, ITP ProjectManager) and SAP tax integration services. Revenue mechanics are quote-based professional services engagements, typically multi-year, with the firm explicitly aiming to undercut Big 4 fee structures via AI efficiency gains and to win share through its non-audit-independent positioning.
