Data Doesn't Lie. People Do.
We don't need testimonials. Here are 3 actual "boring" businesses from our vault that are generating consistent revenue while you overthink.
Sessions
22% one-star reviews. Users frustrated with operations issues and stability.
Build a scheduling tool that just works. Focus on reliability over features.
SalesBlink
Deal ended. No longer available on AppSumo. Demand is orphaned.
Users loved it but can't buy it. Build a modern alternative to capture orphaned demand.
Screpy
Bloated feature set. Doing SEO, monitoring, and more. Too complex.
Unbundle their best feature. Make it faster and simpler. Win over frustrated users.
Simple, Transparent Pricing
Stop wasting months building the wrong thing.
The cost of one failed project is 100x the price of this tool.
The Explorer
Just looking around.
The Hunter
For serious market browsing.
The Architect
For Builders Who Value Their Time.
Less than the cost of 2 hours of dev time.
Agency
For deal flow & teams.
The cost of inaction isn't $0. It's building a product nobody wants for 6 months. That costs you $50,000 in lost time. Spend $49 to save $50,000.
