OpenGreet's answer
OpenGreet.ai was founded by APAC-based builders, headquartered in Singapore, who saw a gap in how businesses handle customer conversations Voice remains essential especially in APAC region, but scaling it is difficult, inconsistent, and resource-heavy We’re building AI voice agents that handle real conversations across accents, languages, and contexts, so businesses can operate more efficiently at scale
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.
