PICK AXO IF
▸Your marketing team owns personalization: no ML engineers or ranking-stack integration on the roadmap.
▸You want to personalize page content (heroes, copy, CTAs, offers), not just re-order lists of items.
▸You want to be live this week from one script tag, on Shopify or any stack.
▸You want holdout-proven revenue lift and a monthly price, not a seven-figure annual API contract.
PICK SEQUEN IF
▸You are an enterprise consumer company where search/reco/feed ranking is the core conversion lever.
▸You already run a relevance stack and have the engineering team to swap its APIs out.
▸You need sub-25ms in-session re-ranking at hundreds of requests per second across a huge catalog.
▸Your product and ML org (not marketing) owns the personalization roadmap.
THE HONEST TAKE

Where AXO wins, and where Sequen does.

Sequen is serious ML infrastructure: in-session sequence models that re-rank your catalog, search results, and feeds in under 25ms, no cookies required. But it is an API swap for enterprise product and ML teams, not a tool a marketing team can run. It re-ranks lists; it does not touch page copy, heroes, CTAs, forms, or overlays. Axo personalizes the whole page from one tag, is live the same afternoon, and proves lift with a holdout, at a price that isn't a seven-figure contract.

WHEN SEQUEN IS THE RIGHT CALL

If you are an enterprise consumer company (large-catalog ecommerce, streaming, travel, rewards) with an existing search/recommendations stack and an ML-capable engineering org, and your biggest conversion lever is ranking quality at massive request volume, Sequen's in-session ranking models are genuinely differentiated, with real pedigree behind them.
