What's the story behind your product?

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.

TechLeads.Fyi's answer:

TechLeads.fyi started with a simple frustration: I wanted to use BuiltWith, but it was way too expensive and still is. As a solo founder, I couldn't justify the cost just to look up a company's tech stack. So I built my own version, one that delivers the same core technographics data without the premium price tag. Today, TechLeads.fyi gives sales, marketing, and dev teams an affordable way to access the data they need to find leads and understand the market.
