Bills you have.
Things you want.
Mumm works in both directions. We fight bills you've already received and negotiate better deals on things you're about to buy.
Got a bill that's too high?
Full of mystery charges? Send it to Mumm. We find the errors, know the fair price, and negotiate it down. You pay less. We handle everything.
- Hospital and medical bills
- Insurance premiums and denied claims
- Contractor invoices and change orders
- Subscriptions and service fees
Want something?
Tell Mumm. We find the best deal, negotiate the price, and unlock perks and upgrades you didn't know were on the table.
- Cars — price, accessories, warranties, financing
- Hotels — rates, upgrades, spa credits, late checkout
- Contractors — competing bids, better terms
- Luxury purchases, trips, experiences
Three steps.
You do almost nothing.
Step 01
Tell Mumm
Text us a photo of a bill. Paste a link to something you want. Or just describe what you're dealing with. That's all we need to get started.
Step 02
We handle it
Mumm contacts them directly — hospitals, hotels, dealerships, contractors, insurance companies. Every call, every email, every follow-up. You do nothing.
Step 03
You pay less
We come back with a better deal. Pay one amount to Mumm — we pay the provider. Lower price, better terms, added perks. You approve it or walk away, no obligation.
If it has a price, we can negotiate it.
Medical Bills
Error detection, overcharge identification, charity care applications, settlement negotiation, payment plans. We know what hospitals actually accept.
Insurance
Premium reductions, claim approvals, denial reversals, policy shopping. Auto, home, health — better coverage for less.
Contractors
Competing bids, scope verification, price negotiation, warranty extensions. We find the padding and cut it.
Cars
Lower price, free accessories, extended warranties, maintenance packages, better financing. We negotiate the whole deal, not just the sticker.
Hotels & Travel
Rate reductions, room upgrades, late checkout, breakfast, spa credits. The perks they don't advertise, unlocked.
Everything Else
Subscriptions, rent, electronics, furniture, experiences. If there's a price, there's a better one.
