What Complementa does

Complementa AG is an independent Swiss investment consulting firm founded in 1984 and headquartered in St. Gallen, with additional offices in Zurich and Munich. It serves more than 200 institutional clients — primarily Swiss and German pension funds, family offices, corporates, foundations, insurance companies, and banks — and reports coverage of over CHF 270 billion in assets under service. Its core offerings include investment reporting, investment controlling, investment consulting, and investment accounting, supplemented by ESG reporting and advisory services, and supported by the proprietary Portfolio Analyzer platform and the long-running Swiss Pension Fund Study covering 460+ funds (≈CHF 940B).

The firm earns revenue through professional-services fees on reporting, controlling, consulting, and accounting mandates, with pricing typically tied to mandate scope, assets covered, and service intensity rather than transaction volume. Go-to-market is relationship-led, anchored by long-tenured institutional clients, the annual Swiss Pension Fund Study, and a longstanding partnership with Zürcher Kantonalbank (ZKB) that culminated in ZKB's full acquisition of Complementa on 26 July 2024, making it a wholly-owned subsidiary. Complementa GmbH in Munich extends the model into the German market, and 2026 partnerships with the CAIA Association and the World Gold Council position the firm as a content and education node in alternatives and gold investing.

Operationally, the firm is credentialed (ISO and ISAE certifications) and staffed by 60+ professionals holding designations such as CFA and CAIA. Independence and product neutrality are positioned as core differentiators versus bank-internal solutions. The technology stack centers on the Portfolio Analyzer tool plus standardized reporting and controlling workflows; there is no disclosed AI/ML capability beyond general productivity tooling.

Complementa offers an integrated platform of investment management services for institutional investors and family offices. The core offering comprises four interconnected service pillars: Investment Reporting (consolidated data aggregation and monitoring), Investment Controlling (performance evaluation and deviation analysis), Investment Consulting (ALM, strategy, and manager selection), and Investment Accounting (NAV and bookkeeping). These are supported by Portfolio Analyzer and Portfolio Management Software tools for client self-service access, plus ESG-Services for sustainability integration.
