Diffyn's answer:

What's the story behind your product?

FaveCard's answer

FaveCard started from a simple observation: paper stamp cards do not work. Customers lose them, businesses waste money printing them, and nobody gets useful data.

Digital loyalty apps exist, but they all require customers to download yet another app. Most people will not install a separate app just to collect stamps at their local cafe.

FaveCard solves this by using Apple Wallet and Google Wallet — apps already on every phone. One tap to add, always visible, never lost.

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.
