Indexus

What Indexus does

Indexus was a Dutch wealth management firm founded in 1997 and headquartered in Amsterdam, offering asset management, investment strategies, and advisory services to Dutch customers. The firm was built around an early-ETF, passive-index philosophy, and over time developed into a discretionary private wealth manager serving retail and small-business clients in the Netherlands and, via the related Dexxi brand, Belgium. Like most wealth managers of its size, Indexus operated as a regulated investment firm, with its parent Semmie Group B.V. holding AFM license 14001994 and operating under DNB supervision and Kifid affiliation.

In 2024, Indexus and Dexxi were consolidated into SemmieWealth, the digital wealth management brand of Semmie Group B.V. The unified platform offers a single model portfolio that combines passive index investing with a private-markets sleeve, delivered through a web portal and a mobile app, and supported by dedicated relationship managers, 7-days-a-week customer service, and an educational content layer (Magazine, Academy, Beleggingswiki). The business now serves three segments — retail (particulier), business (zakelijk), and pension (pensioen) — plus a Premium tier, with Belgian Dexxi and Goudse Verzekeringen accounts continuing through a separate vermogensrapportages.nl portal. Indexus no longer operates as an independent entity, and its website redirects to SemmieWealth.

Direct peers

• BinckBank (part of Saxo Bank): Dutch online broker and wealth platform now part of Saxo Bank, serving retail and business investors with trading, savings and wealth products. Comparable on Dutch retail wealth distribution and on shared infrastructure with Saxo, which is also the custody/execution partner of SemmieWealth.
• DeGiro: Dutch low-cost broker and investment platform serving retail investors with execution, ETFs and related investment products. Comparable as a Dutch mass-affluent/self-directed investment platform competing for the same pool of retail capital, though DeGiro is execution-led rather than discretionary.
• Brand New Day: Dutch digital asset manager and pension/wealth provider offering index-based model portfolios to retail and business clients. Highly comparable to the Indexus/SemmieWealth combination on product (passive index-led), target segments (particulier, zakelijk, pensioen) and distribution model.

• NN Investment Partners: Large European asset manager (now part of Goldman Sachs Asset Management) with a strong Dutch franchise across multi-asset, fixed income, ESG and pension solutions. Comparable as a Dutch-anchored, AFM-regulated asset manager competing for retail, business and pension mandates.
• Van Lanschot Kempen: Largest independent Dutch private bank and wealth manager offering private banking, asset management and investment solutions to HNW and institutional clients. Comparable as a Dutch regulated wealth and asset management franchise operating in the same private-client and institutional segments.

Emerging players
