Questions & Answers

As answered by people managing GroupTogether and Project Euler.

Why should a person choose your product over its competitors?

What's the story behind your product?

GroupTogether's answer

Founders Julie Tylman and Ali Linz have 7 kids between them including two sets of twins. They were spending a huge amount of time shopping, wrapping, and giving gifts that weren't necessarily wanted or needed — so they used simple tech to handle the coordination and "avoid the awkward." GroupTogether was created in 2015 with the mission to help people give better and with less waste. → grouptogether.com/our-story

GroupTogether's answer

GroupTogether's corporate market — employees collecting funds for farewells and staff gift packages — accounts for 50% of the platform's user base. The other half is everyday consumers celebrating birthdays, baby showers, teacher appreciation, and more. → grouptogether.com/us/faqs
