Case Study: Birchbox UK achieves 58% more subscriptions and 60% lower cost per subscription with Paragone.ai

Paragone delivers creative insights to Birchbox UK through Story Ads test

Birchbox, the monthly beauty-sample subscription service, wanted to know which Stories creative — highly polished studio videos or casual self-recorded clips — would drive more subscriptions on Facebook and Instagram. Working with Paragone.ai as their Facebook Marketing Partner, Birchbox UK used Paragone.ai’s split-test capability and creative performance dashboard to run a controlled Stories ads experiment.

Paragone.ai ran A/B tests of studio-recorded versus self-recorded Stories ads and measured outcomes with its dashboard; the self-recorded ads drove 58% more subscriptions and cut cost per subscription by about 60%. The test showed Paragone.ai could deliver measurable creative insights that improved performance while demonstrating that authentic, native-feeling Stories creatives can unlock better results on social.
