Questions & Answers

As answered by people managing GuyID and Diffyn.

What makes your product unique?

GuyID's answer

GuyID is the only consent-based trust verification platform built specifically for dating. Unlike background check services, the person being verified is fully in control - they choose to verify, collect vouches, and share their profile. Identity is checked but never stored. It's trust built on transparency, not surveillance.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

GuyID's answer

Most alternatives are either invasive background checks or unverified self-reported profiles. GuyID sits in the middle - real identity verification combined with peer vouches from people who actually know you, presented as a shareable trust profile. It's proactive, consent-based, and free to use.

Diffyn is the platform that specializes on both change management and multi-model analysis.

How would you describe the primary audience of your product?

Anyone who dates online and wants to build or verify trust before meeting in person. People who verify their profile are proactive about safety. People who request a profile want confidence before a first date.

Diffyn's answer:

What's the story behind your product?

GuyID's answer

Dating apps have solved discovery but not trust. After matching, there's no credible way to know if someone is who they say they are. GuyID was built to fill that gap - a solo founder project launched in March 2026, bootstrapped from idea to product in under 3 months.

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?

GuyID's answer

Early adopters from the online dating community Safety-conscious daters using apps like Tinder, Bumble, and Hinge People who have experienced catfishing or romance scams
