WHY
"ROLLE"
We named our company after a mathematical proof that fairness is guaranteed. Here's why.
WE NEEDED A NAME THAT MEANT SOMETHING. ABOUT FAIRNESS, BALANCE, AND THE MATH BEHIND TRUST.
When you start a company, naming it is one of the hardest things you do. You want something1
We tried hundreds of names. We tried portmanteaus, acronyms, made-up words. Nothing stuck. Then2
A 333-year-old proof that if the conditions are right, a point of balance is guaranteed to3
THE MAN
Michel Rolle was born in 1652 in Ambert, France. He was the son of a shopkeeper, largely4He had no formal mathematical training, yet he went on to solve problems that stumped the
In 1691, he published a theorem so elegant and so fundamental that it would become one of the
THE THEOREM
HOW IT WORKS
If a continuous function takes equal values at two points, then somewhere between
If f is continuous on [a, b], differentiable on (a, b), and f(a) = f(b), then there exists a c in (a, b) such that f'(c) = 0.
THE CONNECTION
Replace "curve" with "second-hand marketplace." Replace "equal values at two endpoints" with
Rolle's theorem says: if the conditions are right, a point of fairness is mathematically8
OUR JOB IS TO CREATE THOSE CONDITIONS.
THE ALGORITHM
Rolle's theorem doesn't just inspire our name. It inspires how we build. Every feature, every
We verify condition so you don't have to guess. We set pricing benchmarks so neither side
THE IRONY
Here's the part we love most: Michel Rolle hated calculus. He called it "a collection of5
Yet his theorem became one of the most important results in calculus — the very discipline he6
WE RELATE TO THAT.

Because we believe fairness in second-hand commerce shouldn't be a matter of luck. It should be
Michel Rolle proved that balance exists when the conditions are right. We build those
Equilibrium shouldn't require a leap of faith.
Second-hand, don't second-guess.
