Stop underpricing projects you can't predict.
You give us your best guess on each task. We run thousands of simulations and give you a price range your data actually backs, with a built-in buffer for the surprises every project hides.
Quote the P80 and you have an 80% chance of delivering on budget.
The planning fallacy
Your best guess is almost always too low.
Research has shown it for decades, and you've probably felt it yourself: people almost always underestimate how long work takes. It's not a discipline problem. It's how human brains work. We anchor on the optimistic scenario and forget to account for everything that could go sideways.
Projectrus works the same way an actuary does. Instead of asking you to predict the future, it asks you to describe the work, then models the full range of what that work could actually cost. The result is a fixed fee you can quote with a specific confidence level behind it, not just a hope.
How it works
Three steps from estimate to confident fee.
Break down the project
Add tasks, set base hours, and grade each one from 1 (routine) to 5 (unknown unknowns). Takes minutes.
Run thousands of simulations
Projectrus runs Monte Carlo simulations right in your browser, playing your project out thousands of times so you see the full range of outcomes instead of one hopeful guess. No server round-trip, no waiting.
Pick your confidence level and quote
Choose how conservative you want to be. You get a price backed by data, plus a breakdown showing which tasks carry the most risk.
Why teams switch
More than a number. A conversation you can win.
Defensible pricing you can explain
Every number traces back to your own estimates and a transparent model. Walk a client through exactly why the fee is what it is. No hand-waving.
See which tasks drive the cost
A cost-driver breakdown ranks the tasks fuelling the most uncertainty, so scope conversations focus on what actually moves the price and the deadline.
Track budget risk in real time
Log actual hours as work lands and watch the forecast tighten. Know early if you're trending over budget while there's still time to renegotiate scope.
Any fixed-fee estimate
Built for software. Useful anywhere estimates justify a price.
We lead with software teams because that's where Projectrus was born. But the same math applies anywhere someone has to commit to a number up front and defend it.

Why we built it
A fixed fee you can actually sleep on.
For ten years I've estimated software projects, on big teams, at small consultancies, and on my own. The work was always different; the problem never changed. I'd be asked to price something full of unknowns, for a client who didn't fully understand what they wanted, and then be held to a deadline I'd committed to on incomplete information. It's a stressful way to work, and it's expensive for both sides when the estimate is wrong.
We all know most projects run long, so why do we keep pretending otherwise? I think it's more honest to admit that humans are bad at estimating and lean on a tool that compensates for it, rather than trusting a single optimistic number. I built Projectrus to cover my own estimating blind spots and automatically improve them over time. I wanted to put the messy reality of an uncertain project into a clear, defensible format I could actually discuss with a client.
I built it because I needed it. If you've ever lost sleep over a number you quoted, it's for you too.
