What's the story behind your product?

CrabTap's answer

CrabTap was built after noticing that most loyalty programs are either paper cards that get lost and forgotten, or expensive software built for big chains with features small businesses never use. CrabTap keeps the simplicity of a paper stamp card, just digitized in a way that actually works for one-person and small-team businesses.

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.
