About Cindrus

Loans should watch themselves.

We started Cindrus because the moment you sign a mortgage, you're on your own — nobody tells you when the market shifts in your favor. We think that's backwards.

Why we exist

Once a mortgage or loan is signed, most people never look at it again — not because it doesn't matter, but because nobody's watching it for them. Rates move, rules change, refinancing windows open and close, and the only people who reliably notice are the ones selling something. Cindrus is built to notice first, and to work for you, not for a bank or a broker.

How we build

Every calculator we ship uses the same public, documented formulas and regulatory limits your bank uses — nothing hidden, nothing invented. We'd rather launch one market well than eight markets half-finished, which is why each country gets its own calculator, tuned to that country's actual rules, built and checked market by market.

What's next

Today, our free calculators are live in eight markets. Next: the full Cindrus platform, which connects to your loan and keeps watching it for you — so you find out the moment refinancing is worth it, instead of a year too late.
