What's the story behind your product?

ReListr.io's answer

ReListr started in 2025: As a Zurich-based entrepreneur passionate about AI, I saw friends wasting hours manually listing thrift finds on different platforms. Traditional tools ignored the chaos of second-hand items—faded tags, stains, odd angles. So, we built ReListr, starting as a side project to automate it with AI. Bootstrapped with a small team, we integrated AI for vision magic and Shopify for seamless ecommerce. Beta tests with local flippers in Switzerland refined it, leading to our launch.

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.

Who are some of the biggest customers of your product?

ReListr.io's answer

ReListr is in early stages onboarding the first beta users.
