An independent, evidence-based evaluation of Jellyfish, move. faster. smarter. together.. Scored across 5 weighted criteria covering website presence, search visibility, trust, market presence, and customer satisfaction.
Overall evaluation score
Jellyfish combines human expertise, agile global delivery, and AI-powered marketing technology to simplify complex marketing challenges and help brands move faster, make smarter decisions, and scale impact across markets.
Weight: 20%
Jellyfish has a substantial official web presence with a detailed homepage, contact page, training section, clear service coverage across media/creative/data/AI, and published contact/address information, but the evidence does not include deeper UX/performance or content-depth validation beyond these site sections.
Weight: 20%
Search visibility evidence is limited to firm domain signals—jellyfish.com is an old domain registered in September 1998 and the site was last updated in October 2025—but no organic rankings, traffic, backlink, or SERP footprint data were provided, so the score is moderate rather than high.
Weight: 20%
Trust signals are strong because the company has verifiable firmographics (founded 2005, 1,001-5,000 employees, London HQ, LinkedIn company page), an official address at The Shard, and a BBB business profile noted as A+, though review evidence is mixed and some platform coverage is thin.
Weight: 15%
Jellyfish shows strong market footprint in the evidence through its global positioning, large employee count on LinkedIn, broad service portfolio, longstanding domain, and presence across multiple third-party platforms including LinkedIn, Clutch, G2, Capterra, BBB, DesignRush, and GoodFirms.
Weight: 10%
Customer satisfaction appears generally positive but not definitive: G2 shows a strong 4.5/5 across 391 reviews and Capterra shows 4.3/5 across 18 reviews, while visible criticisms mention reporting limitations, occasional slowness, and context gaps in metrics, and Clutch/Trustpilot/Google review evidence is absent or unconfirmed.

I found no public self-serve pricing page for Jellyfish's core agency retainers/projects on jellyfish.com; those services appear to be sold via custom quote/contact sales. The strongest concrete public numbers are from Jellyfish's own Training business, where multiple scheduled courses are openly priced at $495 or $549 ex tax for 1-day sessions and $1,099 ex tax for at least one 2-day course. Third-party directories add buyer-qualification signals but should be treated as directory-entered estimates rather than official agency pricing: DesignRush lists a minimal budget of $1,000-$10,000 and Clutch exposes the profile as having hourly-rate/min-project fields, though the accessible snapshot did not show numeric values; GoodFirms lists '< $25/hr', which is likely directory metadata and not a trustworthy representation of this global agency's actual commercial pricing.
Where this pricing information was traced from.
Jellyfish has a limited third-party review footprint in the platforms checked here. I found clear listings for Jellyfish on Clutch, G2, Capterra, and BBB, but not a confirmed profile on Trustpilot or Google that I could match confidently to the agency at jellyfish.com. Of the platforms with ratings, G2 and Capterra show the strongest review volume and generally favorable feedback, while Clutch appears listed but unrated and BBB appears as a business profile rather than a customer-review destination.
391 reviews
G2 shows Jellyfish with a strong average rating and high review volume. The visible page emphasizes analytics, historical data consolidation, productivity tracking, and value-stream insights, but I could not directly read individual review text from the accessible page.
18 reviews
Capterra reviewers generally describe Jellyfish as useful for engineering analytics, dashboards, and visibility into Jira/GitHub-based work. Criticisms in the visible reviews mention limited/custom reporting, slow performance in some cases, and concern that some metrics can miss offline work or be misused.
“Ability to get enhanced reports into sprint metrics over the month/quarter”
“Sometimes tricky to drill down into how things like carryover are being labeled”
“Easy to use dashboards that provide information to manage teams. Love the ability to drill down for details. Well organized.”
“Software is slow and laggy. Takes lots of time to load.”
BBB has a business profile for Jellyfish tied to jellyfish.com in Baltimore, Maryland. The profile shows BBB business details and an A+ BBB rating, but I could not confirm visible customer review text or a consumer star rating on the accessible page.
