ABOUT US
Mumm's the word.
Our name means two things. We mean both.
MEANING ONE
The quiet kind of leverage.
“Mum’s the word” is old English for keep it quiet— “mum” is literally the sound a mouth makes when it stays closed. In a negotiation, that's not politeness. It's power. The side that talks first, talks too much, or shows its hand — loses.
So we do the talking, and we do it quietly. You never explain yourself twice, never sit on hold, never blink first. And what happens in your negotiation stays in your negotiation — your bills, your deals, your data. Kept in confidence, permanently.
Discretion isn't our policy. It's our name.
MEANING TWO
Somebody who handles it.
You know the person. The one who makes the call you've been putting off for three weeks. Who asks for the supervisor. Who reads the fine print twice and doesn't hang up until it's sorted — because you're hers, and nobody overcharges hers.
Not everyone has that person. Now everyone does. Send us the bill you've been dreading, the quote that feels wrong, the trip you wish you could afford — and consider it handled.
Care like family. Persistence like it's personal.
(There's a third meaning, too. We're keeping mum about that one.)
MADE IN WILMINGTON, NORTH CAROLINA
Built in a port town.
Wilmington has been moving cargo up the Cape Fear River — and haggling over it on the docks — for nearly three centuries. Deals are in the water here. We're not a Silicon Valley company; we're from a place where a handshake still means something, and we built Mumm to work the same way.
WHY WE EXIST
The end of take-it-or-leave-it.
For decades, most transactions were take-it-or-leave-it. Negotiating well takes time, expertise, persistence, and a thick skin — most people don’t have all four for any single bill, let alone every one. So the people with pricing teams won, and everyone else paid full freight.
AI collapses that asymmetry. The friction drops to zero, the expertise becomes infinite, the persistence becomes automatic. Every transaction becomes negotiable — and everyone gets a professional in their corner.
Mumm is the infrastructure for that world: a consumer service that negotiates end-to-end today, and the protocol underneath — identity, messaging, price intelligence, reputation, settlement — that the rest of the ecosystem will run on.
How we operate.
Paid only when you win
Our fee is 17.5% of verified cash savings — 14% for Priority members. No savings, no fee. Perks are free.
A human checks every offer
Nothing leaves the building — no email, no call, no deal — without a person reviewing it first.
Mumm's the word on your data
We never sell your information. Sellers see negotiation terms, never your identity or your habits.
Flat fees keep us honest
Merchants pay us a flat closing fee — never a percentage — so we never earn more by letting your price stay high.
Tell Mumm what you want.
We'll take it from here. And we won't say a word.
