Yes, we are a Segment alternative. Thanks for the feedback on positioning. This is something we are still figuring out (and will probably do for a long time).

CDP (Customer Data Platform) is a more widely known space but it's too broad.

CDI (Customer Data Infrastructure) is more relevant but very few people know about it

I agree with you, though perhaps if you don't know what "CDP" stands for ("customer data platform"), you're maybe not in the market for one. The only company I've really heard of in this space is Segment, and their homepage does a better job of explaining what these sorts of things do.

The cynic in me suspects that this is intentionally obfuscated to the readers not already in the know.

Whereaa few of the general public are likely the target user of a CDP (customer data platform), they are likely the actual target of the product: they will have their data and interactions detailely stored and processed via this platform. However well done this may be, it is more comfortable not to be too aware about it.
