# Jellyfish

A digital-marketing agency frequently cited in practitioner discussions of AI-search optimization. It partnered with [[entity-pernod-ricard-d6]] to iteratively prompt and correct LLM perceptions of Ballantine's, popularizing the active management of [[concept-share-of-model]].

**Enrichment note.** The enrichment attributes the *original* introduction of 'share of model' to **Jack Smyth at Jellyfish**, which strengthens Jellyfish's canonical role in this concept's origin story. (Entity note added from enrichment canonical references.)
