Questions, answered
Frequently asked about Jellyfish
The short version is on the surface. Open any question to go deeper.
Jellyfish is an integrated global digital marketing business and media-buying agency that helps brands plan, buy and optimize media across channels while uniting creative, data, cloud and CRM capabilities. As part of The Brandtech Group, it combines agency services with proprietary AI tools such as an AI-powered media in-housing platform, AI Studios, Now Next Soon, J+ Bidding and Share of Model to improve speed, efficiency and effectiveness for mid-market and enterprise advertisers. This profile refers to Jellyfish at jellyfish.com, not the separate engineering intelligence software company at jellyfish.co.
Jellyfish does not publish a standard rate card for its media and agency services. Full-service engagements are typically priced on a custom basis depending on media budget, number of markets, service mix (media, creative, data, cloud, CRM) and whether you are using its in-housing platform or more traditional managed services. Many enterprise clients will be on six- or seven-figure annual retainers, while smaller project-based scopes are also possible. In contrast, Jellyfish's public training courses on topics like SEO, analytics and Google Marketing Platform are transparently priced on its website, with many one-day courses around the $500-$700 per-person range before tax.
Key features of Jellyfish's offering include global media planning and buying across search, social, programmatic and retail media; an AI-powered media in-housing platform that automates media research, planning and activation; AI Studios for rapid creative production using generative AI; Now Next Soon for AI-driven scenario modeling and MMM; J+ Bidding for real-time bid and budget optimization; Share of Model for measuring brand perception in large language models; Social Agents for AI-assisted social marketing; advanced analytics and measurement (GA4, Adobe Analytics, Meridian MMM); CRM and lifecycle marketing built on platforms such as Salesforce Marketing Cloud, Braze and Bloomreach; and a large catalog of digital marketing training courses.
Jellyfish competes with a mix of global agency networks, independent performance agencies and AI-led marketing firms. Common alternatives include Media.Monks, Merkle, iProspect (Dentsu), Brainlabs and Kepler, as well as other Google Marketing Platform and Amazon Ads partners. The right comparison set will depend on whether a brand is primarily seeking media buying, in-housing support, analytics and measurement expertise, or full-funnel creative plus media.
Jellyfish is optimized for brands with significant digital media budgets and multi-market complexity, so its full-service agency and AI platform solutions are generally best suited to mid-market and enterprise organizations. Smaller businesses may still benefit from Jellyfish's public training courses and select project engagements, but they may find more cost-effective options among smaller performance agencies or self-serve ad platforms if their budgets are modest or limited to a single market.
