RewardIQ - Stop leaving rewards behind: Find and use the money you're leaving behind

Hello Product Hunt community, I built RewardIQ because I wanted to solve a massive financial blindspot for business owners without taking on the burden of monthly database fees, server upkeep, or heavy hosting subscriptions. Every year, business owners leave thousands of dollars in card rewards on the table because they do not understand fixed-chart transfer rules vs volatile dynamic pricing. RewardIQ exposes these exact financial gaps. It takes a user spend profile, queries an AI proxy to calculate an annual rewards gap, reveals a single teaser card solution to prove the framework works, and locks the full multi-card roadmap behind an automated payment wall. Once paid, a serverless Stripe webhook captures the transaction, compiles the user metrics into a clean corporate PDF brief, and drops it right into their mailbox inside 60 seconds. The background cron scripts then score the user parameters to sort clients into Platinum, Gold, Silver, or Bronze profiles, routing high-value targets into high-ticket travel consulting packages automatically. The entire application runs flawlessly within a free Google Apps Script environment and a static frontend layer hosted on Cloudflare Pages. I am opening up the full codebase blueprint so other developers, consultants, and creators can launch their own high-margin white-label auditing engines or micro-SaaS calculators with zero server overhead. I will be here in the comments all day to answer your technical questions about the architecture, the code split, or the prompt frameworks. What features or custom auditing niches would you like to see this framework adapted for next? Best, Gerald Akhidenor
