Oneindig Vermogen is a financial education brand founded by Lisette, who has an MSc in Accountancy & Controlling and more than 15 years of financial experience. The brand helps people build wealth and improve their long-term financial security through practical guidance on money management and investing. Its approach focuses on creating a clear system for organizing finances, making a personal investment plan, and building wealth over time, rather than promising quick riches or effortless returns.

Oneindig Vermogen offers a free masterclass that introduces a five-step approach to wealth building, alongside its three-month Oneindig Vermogen program. The program guides participants in setting up their finances and developing a strategy for regular, automated investing. Other resources include the Money Mindset Mastery audio training, a podcast about common investing mistakes, and customer reviews and educational content. The materials are intended for people who want to take action after putting off investing, and who are interested in goals such as greater financial choice, saving for children, or preparing for retirement.
