Companies Using Atlassian Cloud

With 10+ years in web crawling and technographic data analysis, I've examined Atlassian Cloud's footprint across our dataset of 42,828 enriched companies matched to LinkedIn profiles. As of our March 2026 crawl, Atlassian Cloud represents one of the most enterprise-heavy technology profiles in our entire database. The company hit $6 billion+ in annual run rate revenue and 350,000+ customers as of Q2 FY2026 (per Reuters). What follows is a data-driven breakdown of who uses Atlassian Cloud, where they operate, and what the numbers mean for sales and partnership teams.

1. Growth trajectory

Atlassian Cloud's adoption curve tells a clear story of forced migration turned genuine growth. Our detection data first picked up Atlassian Cloud on 3 domains in May 2013. The platform sat in single digits for five years. Then in October 2018, active domains jumped from 4 to 4,200 in a single month. That spike lines up with Atlassian's Server discontinuation announcement, which ultimately ended Server support on February 15, 2024 (per Atlassian). Data Center end-of-life is set for March 28, 2029 (per Atlassian), meaning another wave of forced cloud migration is coming.

From that 2018 inflection point, growth was consistent: roughly 1,000 net new active domains per month through 2024. The platform peaked at 47,890 active domains in December 2024 before settling around 44,700 by mid-2025. The total detected-ever count of 62,002 means only 13% of domains that ever used Atlassian Cloud have stopped, an exceptionally low churn rate. Atlassian's Q1 FY2026 shareholder letter confirmed that Data Center-to-Cloud migrations were up more than 2x over the prior year (per Atlassian).

"The 4-to-4,200 jump in a single month is something we almost never see in our data. It's a textbook example of a vendor forcing a migration event, and it worked. Six years later, Atlassian Cloud has 10x'd from that point." - Mehmet Suleyman, Founder at TechnologyChecker.io

Sales Signal: The addressable market is still growing. With Atlassian reporting 350,000+ total customers and our crawl detecting ~45,000, the actual installed base is roughly 7-8x our detection count. Internal-only deployments (intranets, private Confluence spaces) don't expose a public domain signature. The upcoming Data Center EOL in 2029 will drive another migration wave, potentially as large as the Server EOL event.

2. Customer profile

Atlassian Cloud's customer base is unusually large-company skewed. While 29.4% of customers have 1-10 employees, the combined mid-market and enterprise segment (51+ employees) accounts for 48.1% of all detections. That's significantly higher than most technologies in our database, where micro-businesses typically represent 50-70% of the total.

The age distribution reinforces this. Companies founded in the 2010s make up 36.83% of the user base, but 9.66% predate 1960, including names like Siemens (1847), Unilever (1872), and General Electric (1892). Atlassian's published case studies confirm several enterprise deployments with hard numbers: Rivian saves $2.5M annually (36% tooling cost reduction) plus 750+ hours per person per year with Automation (per Atlassian). Roblox saves $150,000+/year per team after migrating from Wrike to Jira with Solution Partner Modus Create (per Atlassian). Both domains appear in our active dataset.

The 79.54% LinkedIn company match rate is the highest we've seen across hundreds of technology profiles. For comparison, most technologies match at 30-50%. Atlassian reported 80% of the Fortune 500 are customers (per Q2 FY26 shareholder letter).

Sales Signal: Mid-market companies (51-500 employees) represent 30.5% of the base and are likely the sweet spot for services and integration partners. These organizations are large enough to need professional help with Jira/Confluence administration but not large enough to have dedicated internal Atlassian admins.

3. Industry and geographic concentration

Software Development (14.25%) and IT Services/Consulting (13.47%) dominate the industry mix, which is expected for a developer-centric platform. But the combined tech sector share of ~36% is lower than you'd guess for an Atlassian product. Notably, Atlassian reported 50% of its AI users are in non-technical teams like finance, HR, marketing, and ops (per Q2 FY26 shareholder letter). Financial Services at 5.59%, Healthcare at 2.10%, and Insurance at 1.64% in our data confirm that non-tech adoption is real.

Geographically, the US leads at 32.6% but Germany is the #2 market at 8.5%, ahead of the UK (7.0%). This German strength reflects Europe's engineering culture and Atlassian's Frankfurt data center region. adesso, a German IT consultancy with 10,000+ users, consolidated and migrated 50+ Atlassian instances to Cloud Enterprise (per Atlassian). Together, the DACH region accounts for roughly 11% of all Atlassian Cloud customers, based on our enriched company data at TechnologyChecker.io.

Sales Signal: The European market, especially DACH, is underserved relative to its size. Companies like Drupal and Joomla are losing customers to Atlassian Cloud at 35:1 and 118:1 ratios respectively. European partners selling Atlassian migration services have a large addressable market of companies still on legacy CMS platforms.

4. Migration patterns

The migration data is the most lopsided we've recorded for any technology in the CMS category. Atlassian Cloud gained 3,034 companies from Drupal while losing only 86, a 35:1 gain ratio. Joomla is even more extreme: 2,117 gained versus 18 lost, which is 118:1. Squarespace (17:1), Wix (11:1), and WordPress.com Hosting (17:1) all show strongly net-positive flows toward Atlassian Cloud.

The total picture: Atlassian Cloud gained 9,290 companies from tracked CMS competitors and lost only 462. That's a 20:1 aggregate gain ratio. This aligns with Atlassian's own disclosure: cloud Net Revenue Retention (NRR) has been above 120% for three consecutive quarters, and Remaining Performance Obligations grew 44% YoY to $3.8 billion in Q2 FY2026 (per Diginomica). Companies aren't leaving once they adopt.

"A 20:1 aggregate migration ratio is something I've only seen one other time in our database, with Shopify in ecommerce. When every competitor corridor flows one direction, you're watching a category shift, not a temporary trend." - Mehmet Suleyman, Founder at TechnologyChecker.io

Sales Signal: The migration wave creates two-sided opportunity. Companies leaving Drupal and Joomla need migration consulting, data migration tools, and training. And the Data Center EOL in 2029 means a second, larger migration wave is on the horizon. Atlassian solution partners can target the 3,000+ Drupal shops in our data, then prospect the thousands more still running legacy self-hosted platforms.

5. Technology ecosystem

The tech stack overlap reveals Atlassian Cloud's customer base is technically sophisticated. HubSpot (16.74%) leads in marketing automation, suggesting a strong overlap with B2B companies running inbound marketing alongside Atlassian's developer tools. Hotjar (17.96%) and Microsoft Clarity (12.99%) lead in analytics, indicating Atlassian Cloud customers care about UX and behavioral data.

The JavaScript framework data is telling: AngularJS (14.32%) and styled-components (12.01%) top the list. AngularJS adoption at 14% is notably higher than in most technology profiles, likely reflecting the enterprise engineering teams that form Atlassian's core user base. Atlassian's CEO noted that customers using AI code-generation tools create 5% more Jira tasks, have 5% higher monthly active users, and expand Jira seats 5% faster (per Diginomica). More AI adoption means more Atlassian usage, not less.

In live chat, Intercom (5.39%) and Zendesk (3.71%) dominate over budget alternatives, which aligns with the mid-market and enterprise skew of the customer base.

Sales Signal: The HubSpot overlap at 16.74% represents over 7,100 companies running both Atlassian Cloud and HubSpot. Integration partners building connectors between these two ecosystems have a quantified addressable market. The low Tawk.to adoption (1.24% vs. 5.39% for Intercom) confirms these aren't price-sensitive SMBs.

6. G2 review signals

Confluence's G2 reviews paint a consistent picture: ease of use (304 mentions) and team collaboration (213 mentions) are the clear strengths. The top criticism, a steep learning curve (89 mentions), aligns with what we see in our data. The 29.4% micro-business adoption rate is lower than most SaaS platforms, and the learning curve likely filters out the smallest teams that would otherwise try it.

Search functionality issues (67 mentions) are worth watching. Atlassian's Rovo AI product has surpassed 5 million monthly active users, and 78%+ of Rovo Search users say it outperforms any previous enterprise search experience (per Atlassian Q1 FY26). If that holds, the second-biggest G2 complaint is being addressed. Pricing (48 mentions) as the fourth criticism tracks with the enterprise positioning. Confluence Standard starts at $5.42/user/month and Premium at $10.44/user/month (per Featurebase, 2026).

Cross-referencing G2 sentiment with our migration data: despite pricing concerns, the 20:1 migration ratio means companies aren't leaving for cheaper alternatives. They're accepting the price because the Jira+Confluence ecosystem lock-in is strong. The Teamwork Collection bundle (Jira + Confluence + Loom + AI) passed 1,000 customers and 1 million seats in under nine months (per Q2 FY26 shareholder letter).

Sales Signal: The learning curve complaint creates a training and onboarding consulting market. Companies with 50-200 employees are large enough to need Atlassian but not large enough to have in-house expertise. Targeting the 9,318 companies in our 51-200 employee segment with onboarding services is a clear opportunity. Expedia Group's CIO reported 70% company-wide Rovo adoption in just 8 weeks, with 200 AI agents created in 6 weeks (per Deviniti), so the adoption trajectory can be fast with the right support.

7. Key takeaways

1. Market position: #15 in CMS by domain count, but functionally in a different category. Atlassian Cloud competes with SharePoint and Notion, not Squarespace and Wix. The $6B+ ARR and 350K+ customers tell the real scale story.

2. Growth phase: Still expanding. The 2018 Server EOL kickstarted adoption, and the Data Center EOL (March 2029) guarantees another migration wave. Cloud revenue grew 26% YoY in Q2 FY2026.

3. Core customer: Mid-market tech companies with 51-200 employees, founded in the 2010s, headquartered in the US or Germany.

4. Competitive moat: The Jira+Confluence ecosystem creates deep lock-in. NRR above 120% for three consecutive quarters, RPO growth of 44% YoY, and our 20:1 migration ratio all confirm it.

5. AI play: Rovo (5M MAU, 2.4M automated workflows in 6 months, 100B+ Teamwork Graph objects) is the wildcard. If AI makes Confluence's search and authoring significantly better, the second- and third-most common G2 complaints disappear.

6. Key vulnerability: Per-user pricing at scale. As companies grow beyond 100 users, costs accumulate, and alternatives like Notion offer simpler pricing.

8. Sales applications

Outreach template: "Hi [Name], we track technology adoption across 50M+ domains at TechnologyChecker.io. Our data shows [Company] running Atlassian Cloud alongside [co-occurring tech]. Companies with your profile (mid-market, [industry]) typically see value from [specific integration/service]. Would a 15-minute walkthrough of how similar companies optimize their Atlassian stack be useful?"

Targeting strategy: On TechnologyChecker.io, filter for Atlassian Cloud customers with 51-200 employees in Software Development or IT Services, headquartered in DACH region. This segment of ~3,500 companies is underserved by Atlassian's own enterprise sales team and actively needs migration and administration support.

Competitive angle: The 3,034 companies that migrated from Drupal to Atlassian Cloud in the last 5 years likely still have hybrid setups. Target them with consolidation messaging: "You've already moved your documentation to Confluence. Let's finish the migration and retire the legacy Drupal instance." With Data Center EOL approaching in 2029, a second wave of migration is certain.
