What's the story behind your product?

Nossy's answer

Our founder runs a cafe. We built a bot for its bookkeeping, it survived a real tax audit, and grew to 150-200 paying businesses. Customers kept asking for more than accounting, so we built Nossy: AI builds the tailored system, the team runs it in chat. The cafe still runs on Nossy today.

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.

Who are some of the biggest customers of your product?

Nossy's answer

Our first customer is the founder's own cafe, which runs daily operations on it. The team also built zendaibills.com, serving 30,000 local businesses in Thailand
