As answered by people managing DeveloperToolStack and Saasby.
Saasby's answer:
Saasby builds and sells its own SaaS tools. Other lifetime deal sites like AppSumo just resell products from random startups. We control the product, the quality, the updates, and the support. When you buy from Saasby, you're buying directly from the people who built it.
Saasby's answer:
No middleman. Other marketplaces are resellers with no control over what they sell. We build everything ourselves. Lifetime access means you pay once and own it forever. Full support included.
Saasby's answer:
Entrepreneurs, freelancers, small business owners, and founders who are tired of paying monthly subscriptions for software they use every day. People who want to own their tools, not rent them.
Saasby's answer:
I was spending thousands a year on SaaS subscriptions and per user billing. Project management, writing tools, etc—all charging monthly for features that should be a one-time purchase. So I started building my own. Saasby is the result: a marketplace of tools built by the saasby team, sold with lifetime access and no recurring fees.
