Meet Guillaume Decalf, CEO
With a business school diploma in hand, I began my career in France in 2003 as a consultant specializing in process analysis and optimization. In 2010, I left my job to start a career in San Francisco. I worked in different technology companies, including Amazon and Fitbit.
I discovered a world very different from France. A world where the government does not cover health insurance, retirement, and education. Based on this observation, I did in-depth research on the subject to optimize my financial situation as much as possible, and then that of my compatriots in the same situation. My many successes in this area have brought me new demands outside my circle of friends.
So I got my license (Series 65) and launched Oui Financial, my independent financial planning and investment firm, in 2018. I also have the GFP Designation (cross-border financial planning) and the certificate in blockchain and digital assets (RIADAC).
Meet Smara Savoy
Born and raised in the French-speaking region of Switzerland (Suisse Romande), my career began at Nestlé after earning my master’s degree.
In 2013, I transferred to the U.S., where I’ve since lived in several states, including Ohio, before settling with my family of five in the sunny Garden State. Along the way, I experienced firsthand the complexities of navigating finances across borders, particularly between Europe and the U.S.
This curiosity led me to dive deeper into understanding how money works in America and how it differs from European financial systems. After a successful career in HR and Talent Acquisition, I transitioned out of the corporate world and started to pursue my passion for personal finance. I became a Financial Coach and then earned my Series 65 license to join Oui Financial as a Financial Planner and Investment Advisor in late 2024.
I’m excited to help individuals and families navigate the unique challenges of cross-border financial planning with clarity and confidence!
Meet Lindsey Swanson
A Certified Financial Planner (CFP®) from the Bay Area, I’ve dedicated my career to financial services—but it wasn’t always an obvious path. Growing up, I was taught that women weren’t naturally good with numbers. Through education and determination, I discovered that financial literacy isn’t a fixed trait but a skill you can develop and strengthen, just like a muscle.
I’m passionate about breaking down barriers and showing others that anyone can master their financial future. After running my own independent firm for three years, I gained invaluable experience building something from the ground up—insights I now bring to helping clients navigate their own journeys.
What drives me is the powerful combination of empathy and strategy that great financial advising requires. Every plan tells a story, and I love understanding not just the numbers, but the dreams and values behind them. My approach centers on building lasting relationships based on trust and clear communication, empowering clients to make confident decisions about their financial futures.
