How Dyme works

Why you pay less, and where our profit goes.

We buy travel at private rates, keep our markup low and skip the big advertising budgets, so members pay less. Then we put our profits into solar.

Why it costs less

Where the savings come from.

01

We buy at private rates

Hotels and airlines sell some rooms and seats at rates they don't publish, to platforms that only show them to members. Dyme negotiates those rates.

02

We keep our markup low

Hotels and airlines pay us a commission on each booking, so we don't need a big markup on top of the rate.

03

We don't buy ads at scale

The biggest booking sites spend billions a year to win your search. We put that money into lower prices and solar instead.

04

You get the difference

What we don't spend comes off your price. Members save up to 35% compared with public rates.

What advertising costs

$8 billion a year on marketing.

That's roughly what Booking Holdings and Expedia Group each spent in 2025. That money comes out of every booking. We don't spend it, so it doesn't have to be in your price.

Booking Holdings$8.2B

Marketing spend in 2025, 30% of its revenue

Expedia Group$8.2B

Sales and marketing spend in 2025, more than half of its revenue

Where the profit goes

We use our profits to build solar.

Your booking costs you nothing extra. The commission hotels and airlines pay us covers our costs, and our profit pays for solar projects in communities that need cheaper, cleaner power.

01

Cheaper power

New solar is now one of the cheapest ways to make electricity, often cheaper than coal. That means lower bills for the schools, hospitals and homes it serves.

02

Cleaner air

Every hour of solar replaces power that would otherwise come from burning coal or gas, which means less smoke in the air people breathe.

03

Local jobs

Solar employed about 7 million people worldwide in 2024, more than any other clean energy source.

Jobs figure: IRENA, Renewable Energy and Jobs, 2025 review.

Built to grow

More bookings, more solar.

The same model works at any size. Every hotel, airline and store that works with us adds to the commissions, and every new member adds bookings. As bookings grow, so does the solar we can fund.

Questions

FAQs

How does Dyme offer rates up to 35% cheaper?
We book at private rates that hotels and airlines don't publish, keep our markup low, and don't spend on large advertising campaigns. Those savings go to members.
Are prices really all-inclusive?
Yes. The price you see includes taxes and booking fees. The one exception is resort fees that some hotels charge at check-in, which we flag when they apply.
What about my hotel loyalty points and frequent flyer miles?
For flights, add your frequent flyer number on the airline's website using the confirmation code from your Dyme email; most fares earn miles as usual. For hotels, give your loyalty number at check-in. Most major chains credit points and night credit, but Marriott Bonvoy doesn't credit bookings made outside its own channels.
How exactly does my booking fund solar?
Hotels and airlines pay Dyme a commission on each booking. Our profits from those commissions pay for solar projects, which then make clean electricity for 25 years or more.
What if I find a cheaper rate somewhere else?
We'll match it. If you find a lower publicly available rate for the same hotel, same room type and same dates when you book, email hello@dyme.earth with the details.
Do I need a membership to book?
Yes. Private rates are only shown to members. Joining is free and takes about a minute.
