I got tired of digging through scattered retention datapoints, so I built a free tool to compare them

retentionoffercheck.com · 1 day on the radar

Where is the demand coming from?
Leans on the founder
The founder's audience is a large part of it. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimate
We do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 4 days
Nothing patented, no network effect, and no proprietary data set standing in the way.

What it is

RetentionOfferCheck is a free crowdsourced database letting credit card users compare their retention offers (bonus points, cash credits) against recent community reports for the same card. The product solves real friction in personal finance by aggregating scattered, scattered datapoints into one searchable reference.

The one thing to knowZero monetization signals and only 14 total community reports with minimal organic amplification suggest this is pre-traction; a fast-follower could easily replicate the core tool (4-day build) and wedge via distribution to personal finance communities or newsletter audiences where retention offer shopping is discussed.
