Spar vs AB Tasty

AB Tasty hands you the toolkit. Spar hands you the program.

AB Tasty is an enterprise experimentation and personalization platform, now mid-merger with VWO, where EVI and EmotionsAI accelerate a CRO team that already owns the program. Spar is the program itself: it audits the storefront, ranks the bets, drafts the hypotheses, writes the variation code, and declares the winner. AB Tasty assists the team you staffed. Spar is the team, for ecommerce shops that would rather not staff one.

Which one fits the team you have today

Pick AB Tasty if

  • You already run a 3+ person CRO function and need a platform rather than an operator.
  • EmotionsAI's mindset segmentation matches how your brand thinks about audience. No one else ships it.
  • You need server-side experimentation, complex segmentation, or personalization beyond the storefront (finance, travel, media).
  • You need enterprise procurement, EU data residency, and proven coverage across finance, travel, and media.

Pick Spar if

  • Your team is leaner than an enterprise experimentation platform expects.
  • You sell on Shopify and want native theme delivery without a separate dev cycle.
  • You want an audit and ranked backlog produced for you, with no empty workflow to staff.
  • You want a transparent monthly price you can plan around, no enterprise quote, no annual lock-in.
