Real feedback from early users who optimized their wallets with Cardzen.
“I have five cards and used to track them in a spreadsheet. That fell apart in two weeks. Cardzen just keeps everything straight for me.”

“Between shipping AI agents and working nonstop in SF, I never had time to track which credits were expiring. Cardzen caught $120 in Amex credits in my first week, and now just tells me which card to use at checkout.”
