You may never have heard of Cardlytics, but you have probably used its product. The offer list in many U.S. bank apps—“10% back when you spend $50 at a restaurant”—runs on it. On October 6, 2026, it announced a partnership with the travel-rewards platform Rove, bringing that capability into a travel points programme for the first time. This article explains the company.

What Cardlytics is

Cardlytics is a U.S. advertising-technology company, headquartered in Atlanta and founded in 2008. Its business rests on a simple fact: a bank can see every card purchase you make. It turns partner banks’ transaction data into a targeted marketing tool. Brands pay to place personalized offers. Consumers activate an offer in the bank app, spend as usual, and the cash back or points post automatically.

It calls itself a “financial media network”: the bank app is its media placement.

How card-linked offers work

From the user’s side there are three steps:

  1. See the offer: browse personalized deals in the bank app (for example, “5% back at Starbucks”);
  2. Activate: tap to activate. There is no coupon to print;
  3. Spend as usual: use the linked card. After the transaction settles, the reward posts automatically.

No screenshots, no receipt scans, no manual claims. “Cash back when it settles” is the core experience of this kind of product.

How it makes money: two sides of the business

For brands (advertisers), Cardlytics sells advertising whose return you can see:

  • Analyze: use real purchase data to find high-value audiences;
  • Activate: reach them in a high-trust setting, the bank app;
  • Influence: turn new customers, lapsed customers, and infrequent customers into buyers;
  • Validate: card data comes back and measures incremental sales down to “every dollar.”

For banks (the distribution side), Cardlytics sells engagement. Personalized offers make people more willing to open the app and more willing to use that card. What an issuer cares about most is the card’s place in the wallet.

CRP: from bank-only to an open platform

On May 20, 2025, Cardlytics formally launched the Cardlytics Rewards Platform (CRP). It is the largest turn in its business model:

  • Before: only a bank could be its publisher, and offers could live only inside a bank app;
  • After CRP: any company with an online channel and a loyalty programme can be a publisher on the Cardlytics network and embed card-linked offers in its own product;
  • First CRP publisher: a “leading digital sports platform” (not named when it was announced);
  • The logic flipped: an advertiser can also be a publisher. A merchant that already advertised on Cardlytics can now send offers to its own users, a flywheel of “issue rewards → drive spending → collect data → target more precisely.”

The Rove partnership on October 6, 2026 is CRP expanding into travel. Rove members can use Cardlytics’ full offer library, link a payment card, and earn Rove Miles automatically on everyday spending, without a travel credit card.

All three pay you automatically after you link a card. Who sees your transaction data, and how much of it, is very different. Below, Cardlytics is compared with Blue Rewards Card Offers, which Canadian readers know better:

Cardlytics (traditional) CRP (the Rove case) Blue Rewards Card Offers
Channel Partner banks Rove (not a bank) BMO
Data source Partner banks’ transaction data Not disclosed officially. Rove has no transaction data of its own and has to plug into Cardlytics’ data channel BMO’s own data plus the card-network feed (non-BMO cards come back through the Mastercard network)
Data permission The company stresses privacy-first, used inside the bank partnership The press release only describes the user flow (opt in → link an account → activate an offer → earn automatically). It does not describe the data pipe The terms say it plainly: data may be shared with BMO, Blue Rewards, service providers, and participating merchants, and may also be used for marketing
What the user sees Used inside the bank app, in the background Link a card on the Rove platform Link a card in a Blue Rewards account

The comparison is worth reading closely. Blue Rewards’ official terms are quite direct: linking a card authorizes Mastercard to give transaction data to BMO / Blue Rewards, and the authorization is not limited to purchases at participating merchants. Cardlytics’ traditional model keeps data permission narrower. After CRP moves the channel to a non-bank platform, the data pipe is a gap in what has been published so far.

What this means for you

  1. Rove members: there is another way to earn miles that does not depend on opening a card or flying. Everyday spending earns automatically. The actual offers, where they work, and the earn rates are whatever shows in the account. Rove’s own site has not published a partnership page yet.
  2. Canadian readers: Cardlytics’ network is mainly the United States and the United Kingdom. Cards issued in Canada are not in its bank-partner network. The way you can reach it is indirectly, through a CRP publisher such as Rove. How much you can actually use depends on which offers appear in the account.
  3. Privacy: a linked-card rebate is, at bottom, trading transaction data for a reward. Before you authorize it, look at what the terms say the data is for. The Blue Rewards line that data “may be used for marketing” is a cost many people do not notice.

Still to confirm

  • The specific data channel CRP uses outside a bank (a partner bank, a card network, or account aggregation) has not been disclosed officially;
  • The offer range, geographic limits, and earn rates a Rove member actually sees follow what is in the account;
  • Rove’s official partnership page is not live yet.
