Companies Using Joomla

As CMO at TechnologyChecker.io, I've analyzed the Joomla ecosystem across 115,812 domains matched to 68,405 company profiles (59.07% match rate). Joomla tells a unique story in the CMS landscape — a platform with a loyal institutional base that's navigating a challenging competitive environment. Here are the actionable signals for sales and marketing teams.

1. The Institutional Stronghold Signal (Government + Education Dominance)

Key Insight: Unlike WordPress or Wix, Joomla's top companies are overwhelmingly governments, universities, and nonprofits — from NATO and the Government of Canada to the University of Bologna and Sapienza University of Rome. Many of these institutions were founded centuries ago (26.32% of Joomla customers were founded in the 2000s, with 6.24% pre-1960), suggesting deeply entrenched technology stacks.

Prospecting: Target government IT departments and university web teams in Germany (17% of base), Italy (8%), and Spain — these organizations have procurement cycles tied to fiscal years and prefer open-source solutions for compliance reasons. Lead with data sovereignty and self-hosting capabilities in your messaging.

2. The WordPress Migration Tsunami (42,106 Companies Lost)

Key Insight: Joomla has lost 42,106 companies to WordPress while gaining only 8,459 — a devastating 5:1 loss ratio. This is the dominant migration pattern in our dataset. Companies still on Joomla despite this exodus represent committed users with specific requirements that WordPress couldn't satisfy (multilingual support, access control, custom content types).

Prospecting: For WordPress hosting and migration service providers, the remaining 111,637 Joomla domains are a prime target list. Focus on the 85% micro-businesses (1-10 employees) who likely lack internal development resources. Lead with "painless migration" messaging and emphasize WordPress's larger plugin ecosystem.

3. The European Open-Source Network Effect (Germany #1 at 17%)

Key Insight: Germany leads Joomla adoption at 16.96% — nearly 5 percentage points ahead of the US (12.99%). Combined with Netherlands (4.6%), Switzerland (2.4%), and Belgium (1.6%), the DACH+Benelux region accounts for 25%+ of all Joomla companies. This concentration reflects the strong German-language Joomla community, GDPR-driven preference for self-hosted CMS, and European public-sector open-source mandates.

Prospecting: European-focused SaaS companies should treat Joomla detection as a proxy for "prefers open-source, privacy-conscious, self-hosted solutions." These companies will respond to GDPR compliance messaging, EU data residency guarantees, and open-source licensing. Target the Construction (4.95%) and Medical Practices (2.56%) verticals where data sensitivity drives technology choices.

4. Capterra Reviewer Profile: Who Actually Uses Joomla (400+ Reviews)

Key Insight: Capterra's review dataset — with 185 reviews on website building alone — independently validates our technographic findings while revealing the user-voice story behind the numbers. The sentiment split is striking: 91% positive on versatile website building (185 reviews) and 100% positive on open-source flexibility (39 reviews) confirm why institutional users stay loyal — Joomla's power and freedom are genuinely valued by those with the expertise to use it.

But the negative signals explain the migration exodus we detect in our data: 45% negative on complex, outdated interface (65 reviews) — users describe "confusing navigation" and a "dated design" that repels newcomers. More critically, 65% negative on challenging update process (52 reviews) and 71% negative on version migration difficulties (31 reviews) reveal Joomla's operational burden. Updates are "manual, non-intuitive, and can cause compatibility or security issues," while version upgrades create "compatibility problems and outdated extensions." This maintenance friction directly correlates with the 42,106-company loss to WordPress — organizations that lack dedicated web administrators simply cannot sustain the operational overhead.

The 91% positive on comprehensive feature set (44 reviews) — praising "custom fields, multilingual support, and extensibility" — maps precisely to the institutional customer profile we observe: government agencies and universities that need these specific capabilities are willing to accept the complexity trade-off. Meanwhile, the micro-businesses (85% of Joomla's base) who rated the interface poorly are the most likely migration candidates.

Prospecting Signal: Target Joomla sites that haven't updated to version 5.x — these organizations face the exact version migration pain (71% negative) that makes them receptive to managed migration services. For CMS vendors, lead with "zero-downtime migration" and "automatic updates" messaging to directly address Joomla's two biggest operational weaknesses.

Quick Pipeline Hacks

Email: "We noticed your organization uses Joomla — here's how [your solution] integrates natively with Joomla's architecture to [specific benefit] without requiring a platform migration."

Ads: Target the MooTools detection signal (38.29% overlap) as a Joomla proxy — companies running MooTools are almost certainly Joomla users, giving you a secondary targeting dimension unavailable to competitors.

Pro Tip: Filter for Joomla sites in Germany + Construction industry — this is the single highest-concentration segment (4.95% of base) and represents established businesses with real budgets that have consciously chosen open-source over proprietary alternatives.
