SkillVee's answer
SkillVee was created after seeing talented data professionals repeatedly struggle with hiring processes dominated by automated résumé filters and inconsistent interview expectations. The founders built SkillVee to give candidates a fair way to practice real interview scenarios, demonstrate their abilities, and connect with opportunities based on skill—not keywords. The platform joined Stanford StartX, gaining mentorship and support to bring this vision to life.

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.
