Companies Using Popupsmart

With 10+ years in B2B growth strategy and marketing data analysis, I've examined Popupsmart's growth trajectory and customer profile using our 970 enriched company dataset (a 66.6% match rate against 1,456 active domains), as of our March 2026 crawl at TechnologyChecker.io. We matched Popupsmart domains against LinkedIn company profiles to uncover who actually uses the platform, where they're located, and how it stacks up against competitors in the popup and lead capture category.

Growth Trajectory

Popupsmart went from 3 active domains in September 2019 to a peak of 1,561 in December 2024. The most dramatic acceleration happened during August 2020 to July 2021, when active domains exploded from 27 to 433, a 16x increase in 11 months. That's not organic growth. That's a marketing blitz or product-led virality hitting a sweet spot. But the growth curve has plateaued since mid-2023, hovering between 1,300-1,600 active domains. More concerning is the totalDomains metric dropping from 1,818 in December 2024 to 1,281 in July 2025, indicating significant churn as companies test the tool but don't stick with it long-term.

"The 16x growth spike in 2020-2021 wasn't sustainable. Popupsmart caught a wave of businesses going digital during COVID, but the plateau since 2023 and the totalDomains decline tells us retention is the problem, not acquisition." - Elif Arslan, CMO at TechnologyChecker.io

Sales Signal: The 537-domain drop in totalDomains (from Dec 2024 to July 2025) means hundreds of companies churned in just 7 months. If you're selling to Popupsmart users, target the companies that adopted in 2021-2022 and are now hitting renewal decisions. They're the cohort most likely to churn based on the timeline. Position your tool as a retention play, not a growth play.

Customer Profile

Our enriched company data reveals an ultra-concentrated micro-business profile. 75.1% of Popupsmart companies have 1-10 employees, and when combined with the 11-50 range, 90.4% are small businesses. This isn't a mid-market tool. It's a solopreneur and micro-SMB solution. The age distribution reinforces this: 40.8% were founded in the 2010s and another 23.1% in the 2020s, meaning nearly two-thirds of Popupsmart's customer base are digital-native businesses less than 15 years old.

However, additional web research and market intelligence paint a more nuanced picture of who actually pays for Popupsmart. Since Popupsmart offers a generous free plan, our detection data includes both free and paid users, skewing 75% toward 1-10 employee micro-businesses. Among paying customers specifically, the picture shifts dramatically: the 11-50 employee segment converts to paid at a much higher rate, representing roughly ~34% of paying customers, nearly equal to the 2-10 employee range. The companies that pay for Popupsmart are older and more established than the free-tier base, averaging approximately 17-18 years in business. Mature companies (8-15 years old) and established enterprises (16+ years) together account for over 70% of paying Popupsmart customers, suggesting the tool's revenue comes from businesses with existing traffic to convert, not startups still building an audience.

Yet the platform does attract occasional institutional users. Boston University, Agricultural Research Council, and Hong Kong Trade Development Council all run Popupsmart. But look closer at the detection data: Boston University's detection is on sites.bu.edu, a subdomain likely managed by a single department. These are departmental deployments, not institution-wide rollouts. Popupsmart's vendor case studies tell a more compelling story: BermudAir achieved a 13% average conversion rate across 100+ seasonal campaigns with over 1 million popup views (Julie Rempel, Head of Marketing: "Popupsmart has been an essential tool for our seasonal campaigns"). Gemplers hit 5.83% conversion on their Shopify welcome popup with HubSpot integration (Lindsey Vrana, Marketing Manager: "I love the integrations that Popupsmart provides, especially HubSpot"). EuroDNS runs multilingual geotargeted campaigns across Europe from Luxembourg (Tonia Nguyen, Head of Marketing: "Popupsmart made it incredibly easy for us to set up highly targeted and localized campaigns"). These are real results, but none are enterprise-scale operations.

Sales Signal: The sweet spot for selling to Popupsmart users is companies with 1-50 employees (90.4% of the base) that are 5-15 years old. These businesses are past the startup phase, have revenue, and are actively testing conversion optimization tools. For the 9.6% that are larger, pitch a migration play: they're already using a micro-business tool and need something more scalable.

Industry and Geographic Concentration

Accounting dominates at 10.45%, followed by Retail (4.04%) and Software Development (3.44%). No single industry beyond accounting exceeds 5%, which makes Popupsmart a genuinely horizontal platform with shallow roots in any one vertical. The long tail is significant. Retail Apparel and Fashion (3.33%), IT Services (3.33%), Technology/Internet (3.09%), Advertising (2.73%), Non-profit (2.73%), and Food/Beverage (2.73%) all cluster in the 2-4% range, showing that Popupsmart serves everyone but dominates no one. Outside research reveals a fascinating divergence: Financial Services companies are among Popupsmart's highest-value customers despite not appearing in our detection-based top 10, while accounting firms that dominate our ClickHouse data (10.45%) appear to be disproportionately heavy free-tier users. The actual high-value customer verticals are Financial Services, Software Development, IT Services, and Advertising, all of which have stronger commitment profiles than the raw detection numbers suggest.

Geographically, the United States leads with 21.2% of enriched companies (206), followed by Brazil (13.3%), UK (12.7%), India (4.1%), and France (4.0%). English-speaking markets account for 47.2% of the enriched company base. Brazil's #2 position (129 companies) is notable but may be misleading. Additional market intelligence suggests Brazil drops dramatically in paid usage, from #2 in detections to approximately #13, indicating massive free-tier adoption without conversion. By contrast, Canada (5.8%), Netherlands (4.8%), and Germany (3.5%) rank much higher among paying customers than their detection numbers suggest, making them stronger targets for sales outreach. Turkey (25 companies, 2.6%) punches above its weight given Popupsmart's Turkish founding team.

Sales Signal: While accounting firms represent 10.5% of detections, our additional research shows they skew heavily toward free-tier usage. For higher-value targeting, focus on Financial Services, Software Development, and IT Services companies. For geographic targeting, prioritize US, UK, Canada, Netherlands, and France over Brazil, which has high detection numbers but lower commitment rates. Turkey's 3.2% share among paying customers punches above its detection weight, making it a strong target for localized outreach.

Migration Patterns

Platform migration data tells a mixed story about Popupsmart's competitive position. 17 companies switched from OptinMonster to Popupsmart while only 12 went the other direction, a 1.4:1 gain ratio. Against Popup Builder, the ratio is stronger at 4.3:1 (13 gained vs. 3 lost). But here's the problem: 14 companies left Popupsmart for Popconvert in the last year, with only 1 going the other direction. That's a 14:1 loss ratio in a single 12-month period.

The OptinMonster and Popup Builder gains are modest in absolute numbers (17 and 13 respectively), so Popupsmart isn't winning massive cohorts from competitors. It's picking up small batches of dissatisfied users. But the Popconvert losses are concerning. 14 companies in a year, all recent, suggests a product or pricing gap that Popconvert is exploiting.

"The 14:1 loss ratio to Popconvert in the last year isn't just a competitive data point. It's a map of where Popupsmart is failing. Every one of those 14 migrations represents a company that decided Popconvert offered something Popupsmart didn't, and that gap is accelerating." - Elif Arslan, CMO at TechnologyChecker.io

Sales Signal: Companies that recently left Popupsmart for Popconvert are in active replacement mode. They've already decided popup tools matter, they've tested one, and they're now optimizing. Target the 14 companies that switched to Popconvert in the last year with messaging about why your tool solves the gaps they found in Popupsmart. The 17 companies that left OptinMonster for Popupsmart did so primarily for cost and simplicity, per G2 reviewer sentiment.

Technology Ecosystem

The tech stack data reveals what a typical Popupsmart site looks like in 2026. Google Analytics leads at 75.1%, while Hotjar appears on 12.5% of sites, showing that Popupsmart users care about visitor behavior tracking. For marketing automation, Klaviyo leads at 11.5% with HubSpot close behind at 9.0%. That 1.3:1 ratio is tighter than most categories, where Klaviyo usually dominates by 2-3x. It suggests Popupsmart's user base skews slightly toward B2B (HubSpot's strength) rather than pure DTC (Klaviyo's core).

E-commerce adoption is low: Shopify at 5.8%, Webflow Ecommerce at 2.0%, and Wix Stores at 1.3%. That means over 90% of Popupsmart users are not running e-commerce platforms we track, or they're on WordPress/custom builds. CMS adoption is similarly low: Squarespace at 2.5%, Wix at 1.4%, and Weebly at 1.2%. This low CMS/e-commerce overlap suggests Popupsmart's core use case is lead generation on content sites, not e-commerce conversion optimization.

Sales Signal: The 88.5% of Popupsmart users with no marketing automation tool represent a massive upsell opportunity. If you're selling email marketing or marketing automation, target this segment with messaging about connecting popup leads to nurture campaigns. For analytics vendors, the 75% Google Analytics penetration is a baseline, but the 12.5% Hotjar overlap shows that Popupsmart users who care about conversion optimization already use session replay tools.

G2 Review Signals

I've cross-referenced our crawl data with G2 (4.5/5, 137+ reviews), Shopify (4.9/5, 75+ reviews), Capterra (4.5/5, 46 reviews), and Trustpilot (4.1/5, 37 reviews). The patterns align across all platforms. Users consistently praise ease of use and no-code setup, which tracks with our adoption data: 75.1% of Popupsmart users are micro-businesses with 1-10 employees who need zero-friction tools. The main pain point? Limited customization on the free plan and integration bugs with Shopify and WordPress.

Here's where our data adds context: the 14 companies that left Popupsmart for Popconvert in the last year are likely the segment these reviews describe. Popconvert charges no SaaS fee for certain tiers and offers deeper customization, the exact complaints G2 and Capterra reviewers highlight. Trustpilot's lower 4.1/5 rating (vs. G2's 4.5/5) suggests that actual paying customers hit more friction than G2's broader review base, which includes free-tier users.

Sales Signal: The customization complaint is an opportunity for tools that extend popup functionality. If your product adds advanced targeting, dynamic content, or A/B testing to popup tools, lead with the "Popupsmart is great for basics, but when you need [feature], you need us" angle. The Shopify/WordPress integration bugs suggest an opening for reliability-focused alternatives, especially for e-commerce users where downtime costs conversions directly.

Key Takeaways

1. Popupsmart is a micro-business tool, not an SMB-to-enterprise solution. 75.1% of users have 10 or fewer employees, and 90.4% have under 50. The rare enterprise names in the data are departmental deployments, not company-wide infrastructure.

2. Growth has plateaued since 2023, and churn is accelerating. The 537-domain drop in totalDomains (Dec 2024 to July 2025) indicates retention problems. The 16x growth spike in 2020-2021 was a COVID-driven anomaly, not a sustainable trend.

3. Accounting firms dominate detections but not value. At 10.5% of enriched companies, accounting leads in raw numbers, but additional market intelligence shows Financial Services, Software Development, and IT Services are the highest-value verticals.

4. Brazil's #2 detection position is misleading. Our research shows Brazil drops to ~#13 in paid usage, while Canada, Netherlands, and Germany punch well above their detection weight. For sales targeting, prioritize US, UK, Canada, Netherlands, and France.

5. Popconvert is stealing users at scale. 14 companies left for Popconvert in the last year, with only 1 going the other direction. That 14:1 loss ratio is a red flag for Popupsmart and a roadmap for competitors.

6. 88.5% of users have no marketing automation. Klaviyo and HubSpot only reach 11.5% and 9.0% respectively. Email marketing vendors have a massive greenfield opportunity to upsell popup-to-email workflows.

Sales Applications

Outreach template for Popupsmart users:

"Hi [Name], I noticed [Company] runs Popupsmart alongside [Google Analytics/no marketing automation]. Our data shows that 88% of Popupsmart users don't connect their popups to email nurture campaigns, which means those leads go cold. Are you seeing gaps in lead follow-up or conversion tracking? Happy to share what we're seeing from similar [industry] companies using popup tools."

Targeting strategy: Filter the Popupsmart install base by company size (2-50 employees), industry (financial services, software development, or IT services), geography (US, UK, or Canada), and tech stack (Google Analytics present, but no marketing automation). This narrows to the highest-conversion segment: businesses large enough to have revenue but small enough that a single tool can move their metrics.

Competitive angle: Don't lead with "Popupsmart is bad." Lead with the churn problem. The 537-domain totalDomains drop (Dec 2024 to July 2025) gives you a data-backed reason to open this conversation: "A lot of companies try Popupsmart and churn within 6-12 months. Here's what they're missing." The 14 companies that left for Popconvert in the last year are your highest-intent prospects. They've already decided to switch once; they'll switch again if you solve the gap Popconvert didn't.
