Every evening, bakeries throw away bread nobody bought. So I thought

First draft About 2 min

01 Hook

Every evening, bakeries throw away the bread nobody bought.

02 Problem

A fifth of what a bakery bakes ends up in the bin.

03 Solution

Crumb sells it nearby at half price, an hour before closing.

04 Proof

Forty bakeries already bring us

05 Ask

Help us bring Crumb to every bakery in town.
