What Krieger does

KRIEGER is an owner-managed, interdisciplinary professional services firm headquartered in Frankfurt am Main, founded in October 2008 by Dr. Alexander Krieger. The firm delivers integrated tax advisory, audit, legal consulting, real estate accounting, and fund administration services through multiple legally independent entities: KRIEGER GmbH Steuerberatungsgesellschaft, KRIEGER GmbH Wirtschaftsprüfungsgesellschaft, KRIEGER Partnerschaftsgesellschaft mbB, and KRIEGER GbR. It operates from four locations — Frankfurt (headquarters), Lampertheim, Berlin, and Luxembourg — and serves primarily German mid-market companies and real estate investors, alongside healthcare professionals (doctors and pharmacists), young companies, and private individuals. KRIEGER's KRIEGER Fund Services subsidiary administers property funds and alternative investment vehicles, with approximately €11 billion in client assets under management.

The firm's core technology differentiator is KIMS 4.0 (KRIEGER Immobilien Management System 4.0), a proprietary integrated property management system that digitally connects real estate management and accounting workflows. Supporting tooling includes a custom web-based invoice approval workflow with DATEV and online banking interfaces, a Nextcloud-based KRIEGER Dataroom for secure document exchange, a DATEV-integrated mobile document scanning app, and the Circula travel expense application. The firm has been recognized twice consecutively as a DATEV Digitale Kanzlei for its digital work processes. Country-specific desks support cross-border engagements in Italy, Spain, the UK, France, and Luxembourg. Affiliated entity Digital Office 24 GmbH delivers 100% CO2-neutral digital back-office collaboration services.

KRIEGER operates a sales-led, referral- and reputation-driven go-to-market with quote-based professional services pricing. Revenue is generated across six primary streams — tax advisory, audit, legal consulting, fund accounting, back office outsourcing, and real estate accounting — with cross-selling across disciplines an explicit part of the client acquisition motion. Marketing is driven by content (multilingual website/blog in German, English, Italian, and Spanish), LinkedIn, Xing, YouTube, Facebook, client seminars, and earned media coverage in outlets such as the Frankfurter Allgemeine. Approximately 80 employees serve an undisclosed revenue base, and no external funding, M&A, or capital markets activity is disclosed.
