The customer worth reaching first is the one who tries a new tool before it is obvious. They are early too. A coupon is how an early product gets in front of them, and an agent is how both sides of that exchange already work.
Dealpuffin is built for that pair. A founder connects a Stripe read-only key and publishes the coupons they want used. An early adopter, or the agent acting for them, claims a code and pastes it at checkout.
Early products and early adopters are trying to find each other. The product wants people who will actually try it. The person wants a reason to start today, on a tool that is still new. A coupon is that reason, and most indie products already know how to make one. It lives in Stripe.
The hard part was never inventing a discount. It was putting that discount in front of the right people without standing up a second checkout, a lifetime-deal marketplace, or a pile of one-off codes in email.
Dealpuffin is that layer.
