PVADeals's answer

PVADeals was born from a simple frustration—too many services demand phone verification, yet using your real number means spam calls, privacy risks, and unwanted exposure.

We saw the gap: existing solutions relied on VoIP numbers that major platforms actively block, or required personal information that defeated the purpose of privacy.

So we built something different—a platform offering real carrier numbers paired with anonymous crypto payments. No identity checks, no recurring fees, just straightforward verification when you need it.

What started as a tool for privacy-conscious individuals has grown into a reliable service trusted by marketers, developers, and users worldwide who value both functionality and anonymity.

Today, PVADeals continues to evolve—expanding our number inventory, adding more supported services, and refining our platform to make phone verification simple, private, and accessible to everyone.

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.

PVADeals's answer

We prioritize user privacy—which means we don't track, identify, or disclose who our customers are. That's by design. What we can share is the types of users who rely on us:

Digital marketing agencies managing campaigns across multiple platforms E-commerce sellers verifying accounts on marketplaces Software development teams running QA and testing workflows Crypto and Web3 projects needing verification without identity exposure Privacy-focused individuals protecting their personal numbers

Our crypto-only payment model means we don't collect customer identities—so we genuinely don't have a "customer list" to share, and that's exactly how our users prefer it.
