About CardIQ

We built the tool we wished existed.

CardIQ exists because most credit card comparison sites bury you in generic lists. We wanted something that actually looks at how you spend and tells you the exact dollar amount you're leaving on the table.

The Problem

The average American is using the wrong credit card for their lifestyle and losing hundreds of dollars a year in unrealized rewards. The right card for a road-tripper who spends $800/month on gas and groceries is completely different from the right card for someone who lives in restaurants and travels twice a year for work.

But credit card sites treat everyone the same. They rank cards by welcome bonus size or affiliate payout, not by what actually matters: how much you'll earn on your real spending.

How CardIQ Works

CardIQ connects to your bank account using Plaid, the same technology behind Venmo, Robinhood, and Coinbase, to get a read-only view of your recent transactions. We never see your login credentials and we can never move money.

We then run your transaction history through our recommendation engine, which:

1.Categorizes every transaction: dining, travel, groceries, gas, streaming, and more
2.Calculates what you would have earned on each card in our catalog at that card's actual reward rate
3.Subtracts the real annual fee (net of any credits and offsets) for each card
4.Ranks every card by net annual value, showing the actual dollars you'd pocket

The entire analysis takes about 10 seconds. Your results are shown instantly and never stored on our servers. They live only in your browser session.

Our Commitment to Transparency

CardIQ earns a commission when you apply for a card through a link on our site and are approved. This is how we keep the tool free for everyone.

We are committed to one thing: the rankings are never influenced by commission rates. Every card is ranked purely by the math of your spending. If a card that pays us nothing is your best match, that's what we'll recommend.

We also make clear that our catalog covers a curated selection of major cards. There may be cards outside our catalog that are equally or more suitable for you. We encourage you to do your own research before applying.

Privacy and Data

We take data minimization seriously. Here's exactly what happens with your information:

We access only transaction data. No account numbers, no routing numbers, no login credentials
Your transaction analysis is computed in your browser session and never written to any database
When you close the tab, the data is gone. We have nothing stored to delete
We do not sell data, share data with advertisers, or build profiles on users

Who Built This

Hey, I'm Lance. I built CardIQ because I kept running into the same frustration. I'd spend way too long on credit card comparison sites and walk away with nothing useful. The lists were endless, the "best card" picks felt random, and none of them were looking at how I actually spend money.

I travel a fair amount and eat out more than I should. I knew there had to be a card that was genuinely better for my lifestyle, I just couldn't figure out which one without doing all the math myself. So I did — first in a spreadsheet, then into something I could actually share.

CardIQ is just me. No investors, no editorial team, no deals with card issuers. The only way I make money is if you find a card you love and apply through a link here. That keeps my incentives pretty simple: give you the most honest recommendation I can.
