Tired of waiting for a forward curve?
Forward curves and swap rates for anyone who builds a debt model, without asking the bank.
No card needed · 14-day free trial
The model is ready. The curve isn't.
The curve sits with the bank, the adviser or the one colleague with a terminal. You ask, you wait a day, and the model runs on last month's assumption in the meantime.
Then the investment committee, the lender or the auditor asks which curve the debt was sized on, and from when.
“It's really annoying. We got to call a bank every time we want to update a swap… or bang our heads against [a free rates site] to get the right data points.”
The same project, sized a month apart
18-year senior debt on 6M SOFR, repaid semi-annually, sculpted to a 1.30x DSCR and 75% hedged. We sized it on the 1 October curve, then again on 30 October.

Questions buyers ask us
Where does the data actually come from?
Indicative mid rates, updated through the trading day and checked against traded levels. The method is published, so you can show your auditor how each curve is built.
Can we pull a curve as of a past date?
Yes. Every curve is timestamped, so you can pull it again as of a past close, such as last month or last quarter end, in the app or the add-in.
How close are you to the bank's mid?
Within a basis point of bank mids on the curves customers test. Run the same test in your trial on the curve your deal uses.
Is it the bank's price or the mid?
The mid, with no bank margin or funding cost added. We give you the figure; the decision on the quote stays yours.
How often does it refresh?
About every 30 seconds, on every plan. Every number carries its timestamp.
We only need a curve now and then. Is there a plan for that?
Yes. The Individual plan is one user, monthly by card, and you can cancel at any time.
Can we show the data to our own users?
Showing rates inside your product and redistributing the raw data are licensed separately, and we scope both before you integrate. Book a short call and we'll set out what your plan covers.
