Your Finances Deserve 30+ Years of Experience
Daron R. Hays
Engineer • Builder • Investor • Entrepreneur • Founder
I built my first house at 18. Construction and real estate investing have been part of my life ever since. Even after my engineering degree 10 years later, and working as a structural engineer, I was soon right back to doing what I love — construction and real estate investments. This is a passion of mine, and 100+ investments later, I believe that the best decisions start with the best knowledge. CertusFX carries that same conviction into currency data — the rates, yields and trend context behind money decisions, in seconds.

Built to Help You Succeed
The CertusFX data engine was designed from decades of personal experience in investments, engineering and construction — every rate, yield and trend that matters for a confident currency decision, provided in seconds.
CertusFX exists to help you make the best possible informed currency decisions — to see where a rate stands, where it has been, and what is moving it. I built CertusFX the way I build everything — with precision, transparency, and a focus on creating both short term and long-term value for you.
Get Professional-Grade Context
My goal is to give you the best possible data and information, to help you make the best decisions possible. Why get outsmarted by a better-informed counterparty? CertusFX gives you the same market context professionals watch — spot history, government bond yields, and rate differentials — the same context I use for my own decisions. Knowledge is power — use that power to time transfers with confidence, compare providers, and sometimes, yes, to wait for a better rate.
What This Means For You
Make your next currency decision with confidence. CertusFX is built by someone who has personally completed 54 construction projects, managed private capital, operated multiple businesses, and analyzed hundreds of deals. Every feature exists because of real experience.
For People Moving Money
CertusFX gives you the same rigorous market context used by professionals — the rates, the yield story behind them, and the trend — now available for your transfers and travel money.
For Partners and Affiliates

For Companies and Collaborators
