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

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
