Founded by a travel enthusiast from Vietnam, Gohub was born after experiencing the frustration of getting lost in Tokyo without internet, overpaying for eSIMs, and dealing with poor service abroad. Determined to fix these pain points, the founder built Gohub to deliver fair pricing, seamless eSIM activation, and world-class customer support.
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.
