Companies Using Perplexity

With 10+ years in web crawling and technographic data analysis, I've analyzed Perplexity's explosive growth from zero detections to over 541,000 active domains in under a year, enriching 55,843 of them with firmographic data (a 55.84% match rate) at TechnologyChecker.io. Perplexity isn't a typical SaaS adoption story. It's an AI-native platform that spread through website embeds at a pace we've rarely seen in our crawl data. Here's what our March 2026 crawl reveals for sales teams targeting this install base.

Growth Trajectory

Perplexity's growth curve is unlike anything else in our database. Perplexity went from 713 active domains in May 2024 to 458,415 by September 2024, a 643x increase in just four months. It peaked at 541,136 active domains in April 2025 before settling to 486,276 by July 2025, a 10.1% decline from peak. That post-peak contraction is worth watching. The 77,537 domains that have already stopped using Perplexity (our previouslyUsedCount) suggest some of the initial adoption was experimental or driven by a platform-level integration (Squarespace, as we'll see) rather than deliberate individual choice.

Sales Signal: The growth curve tells two stories. For vendors targeting AI-curious businesses, the 486,276 active domains represent the largest reachable audience in the AI Search category by a wide margin. But the 10% decline from peak also signals that the easiest-to-churn users are already leaving. Companies still running Perplexity after 12 months are stickier prospects than the initial wave.

"Perplexity grew faster than any technology I've tracked in 10 years. From 713 to 541,000 domains in 11 months. The question isn't whether AI search is real. It's whether the Squarespace-driven adoption wave represents genuine user intent or platform-level embedding." - Mehmet Suleyman, CEO at TechnologyChecker.io

Customer Profile

89.85% of Perplexity customers have 1-10 employees, the highest micro-business concentration we've recorded for any technology with 50K+ enriched companies. Only 0.39% of the user base qualifies as large enterprise (10,001+ employees), but that thin slice includes Bank of America, Oracle, General Motors, T-Mobile, and Costco. The 2010s cohort dominates at 44.52%, with 2020s companies close behind at 31.66%. Combined, companies founded after 2010 account for 76.18% of the install base. Young, digital-native companies make up the bulk of this install base.

The enterprise detections tell a revealing story. Bank of America's detection sits on ftp-hbs.bankofamerica.com (an internal tools subdomain). Costco's is on sameday.costco.com. These aren't company-wide AI search deployments. They're departmental experiments, likely by individual teams exploring Perplexity's API or embedding its search widget on specific properties. Perplexity's vendor site doesn't publish a public customer or case study page, so we can't cross-reference these detections with vendor-verified accounts. That's typical for a pre-revenue or early-stage AI company focused on user growth over enterprise sales collateral.

Sales Signal: The 89.85% micro-business concentration makes this an unusual install base for B2B sales. But the 377 companies with 10,001+ employees are high-value targets for AI consulting, integration services, and security compliance tools. These enterprises are experimenting with AI search on non-critical subdomains. They'll need governance, SSO, audit logging, and procurement compliance before expanding usage.

Industry & Geographic Concentration

Perplexity is the most horizontally distributed technology in our database. The top industry, Business Consulting and Services, holds just 4.81%. Advertising Services (3.08%), Non-profit Organizations (3.05%), and Design Services (2.97%) follow. No industry exceeds 5%. This flat distribution reflects a technology adopted by individuals within organizations, not purchased through procurement. Geographically, the United States accounts for 49.83% of all enriched companies, with the UK at 9.09% and Australia at 6.35%. English-speaking countries represent 72% of the total base. France (1.57%) and Germany (1.48%) lead the non-English-speaking markets.

Sales Signal: The flat industry distribution means Perplexity users can't be targeted by vertical. Instead, target by company age (founded 2010+) and size (1-10 employees). The 72% English-speaking concentration also signals that Perplexity hasn't localized aggressively. Companies selling translation, localization, or multilingual content tools have an underserved 28% of non-English Perplexity users to reach. See our Google Analytics page for the most popular analytics tool among Perplexity users (36.21% overlap).

Migration Patterns

Migration data is thin, which is expected for a category that barely existed before 2024. The small absolute numbers in competitive migration data don't signal competitive weakness. They reflect the category's immaturity. Most Perplexity adopters aren't migrating from another AI search tool. They're adopting AI search for the first time.

Sales Signal: Migration-based prospecting won't work here because the category is too new. Instead, look at the 77,537 domains that have already dropped Perplexity. These are companies that tried AI search and walked away. Understanding why they left (cost, performance, compliance concerns) creates a targeted list for alternative AI search vendors or for Perplexity partners building retention tools.

"In a category this young, the 77,537 domains that already dropped Perplexity are more interesting than the competitors. These are companies that tested AI search and decided it wasn't ready. Every one of them will revisit that decision within 18 months." - Mehmet Suleyman, CEO at TechnologyChecker.io

Technology Ecosystem

The tech stack data reveals Perplexity's dominant deployment pattern. Squarespace appears on 89.65% of Perplexity domains, with Squarespace Hosted at 89.56% and Squarespace Add to Cart at 68.53%. This isn't a coincidence. The vast majority of Perplexity detections come from Squarespace-hosted websites, suggesting the platform integrated with Squarespace at a platform level (possibly through a native widget, app, or default script injection). Beyond Squarespace, the stack is standard small-business web: Google Analytics (36.21%), Google Tag Manager (37.46%), Facebook for Websites (93.9%), and Let's Encrypt (88.2%). The 48.96% overlap with Google Apps for Business confirms this is a Google Workspace-centric user base. Slack at 14.0% overlap further reinforces this as a digitally native, collaboration-tool-savvy audience.

Sales Signal: The 89.65% Squarespace overlap creates a clear targeting filter. If you're selling to Perplexity users, you're selling to Squarespace users. Tools that integrate with Squarespace's ecosystem (payment processors, booking widgets, email marketing add-ons) can reach the Perplexity install base by proxy. The 36.21% Google Analytics overlap also signals opportunities for advanced analytics tools targeting small businesses who've outgrown basic GA.

Key Takeaways

1. Perplexity achieved the fastest technology adoption in our database: 713 to 541,136 active domains in 11 months, driven largely by Squarespace platform integration.

2. The install base is 89.85% micro-businesses (1-10 employees) and 76.18% companies founded after 2010. This is a digital-native, small-business audience.

3. The 10.1% decline from April 2025 peak to July 2025 suggests the initial adoption wave included experimental deployments that are now churning.

4. Enterprise presence is limited but notable: Bank of America, Oracle, Meta, General Motors, and Costco all show subdomain-level deployments, indicating departmental experimentation rather than company-wide adoption.

5. No meaningful competitive migration data exists because the AI Search & Discovery category is too new. Perplexity users aren't switching from competitors. They're first-time adopters.

6. The 89.65% Squarespace overlap is the defining characteristic of this install base. Perplexity's adoption story is inseparable from Squarespace's ecosystem.
