What's the story behind your product?

Cosmos Video's answer

Cosmos was founded in 2020 by Karan Baweja and Rahul Goyal to solve the fundamental problems of remote work: isolation, meeting fatigue, and lost team culture. They saw colleagues struggling with "working remotely on your own is lonely and isolating" and recognised that "inviting people to meetings for quick collaboration is painful."

Instead of another video conferencing tool, create a virtual office that feels alive – where you can see colleagues at their desks, walk over for quick chats, and maintain the spontaneous interactions that spark creativity and build culture. Today, Cosmos serves thousands of users across creative studios, agencies, and educational institutions.

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.
