Hi Product Hunt, I’m launching Fynn to test a simple idea: credit card recommendations should be transparent. Most card sites feel like black boxes or affiliate-driven lists. I wanted to build something that matches cards to your spending, goals, fee tolerance, and credit profile, then actually shows the reasoning behind the result instead of just saying “trust us.” What Fynn does right now: Gives explainable card matches based on your profile Estimates usable value, not just flashy headline rewards Lets you browse cards and compare them side by side Includes optional bank-linking ideas for making spend inputs more accurate A couple honest notes: Plaid is still on a trial setup, so bank connections may not work reliably yet There are no live affiliate links, and Fynn is not making money right now This is an early prototype, and I’m mainly validating whether this should exist I’d especially love feedback on: Whether the recommendations feel trustworthy Whether the explanations are actually useful What would make you try a tool like this for real If you try it, thank you. If you tear it apart, also thank you. That’s exactly why I’m launching it. Important note: this is an early prototype. Plaid is currently on a trial setup, so bank connections may not work reliably yet. There are also no affiliate links live right now, so Fynn is not generating revenue. This launch is about validating the idea and getting feedback.
