"I built Varen around a problem a lot of developers run into: APIs change quietly, and you usually find out too late. Varen catches those changes automatically across 109 APIs. The core infrastructure is already in place, including source monitoring, diffing, classification, and scheduled scans, and there is a lot of room to grow from here."

An app for content creators: upload a video and get a score and report on how viral it could be. Steady new users every month, low running costs, and plenty of room to grow with better marketing. Not in a rush to sell. Happy to talk with serious buyers.

PDF Vault
PDF Vault is a done-for-you digital business-in-a-box. Members license ready-to-sell PDFs that come with a hosted sales page, and they keep 100% of their sales. It earns money two ways: one-time license fees plus recurring monthly hosting. Tiered pricing raises the price as licenses sell, so each product earns more as it fills and early buyers move fast. Licenses are capped, and new products launch in weekly drops, so the doors open just once a week. That scarcity creates real urgency.
