About

The firm offers comprehensive financial planning, single‑topic financial consulting billed on an hourly basis, and discretionary portfolio management, and it may recommend third‑party managers through its custodian platform. Although organized as an investment manager, the brochure reports the firm managed no client assets as of March 10, 2026.

For portfolio management the firm uses model portfolios and methods such as strategic and tactical asset allocation, fundamental analysis, and modern portfolio theory, and it may integrate separately managed accounts or third‑party sub‑advisers available on the custody platform. The firm generally seeks discretionary trading authority, conducts periodic rebalancing, and provides regular account reviews to clients.

Distinctive aspects include the use of hourly consulting—an uncommon billing approach for firms in its investment‑manager peer group—and a hybrid service mix that pairs fee‑for‑service planning and consulting with AUM‑based portfolio management despite currently reporting zero assets under management. The principal also provides coaching and consulting to other advisory firms and participates in financial planning curriculum development, activities that extend beyond typical portfolio management services.

Fiat Lux Financial Planning's core values are rooted in the belief that financial planning should be accessible to everyone, regardless of their wealth or stage in life. We aim to listen closely, clarify complex topics, and increase clients' confidence in their financial decisions. Our founder, Kate Wilusz embarked on her financial planning career in 2004. Over the course of two decades, she established a highly regarded financial advisory firm and emerged as a prominent figure in the Bay Area financial planning community. In 2024, driven by the desire to extend high-quality financial planning services to a broader audience, Kate founded Fiat Lux. Kate's financial planning expertise includes retirement planning, insurance analysis, employee benefits, tax strategies, education planning, and estate planning. She also possesses extensive knowledge in equity compensation, executive compensation, investment real estate, liquidity events and small business topics. Kate is currently pursuing a master’s degree in advanced financial planning as part of her commitment to being a lifelong learner. She participates in national and local financial planning communities and actively contributes her expertise through pro bono initiatives. Beyond her work, Kate enjoys exploring redwood forests and coastal trails, traveling the globe, and adventures in her 1972 VW bus.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
