Companies Using WhatsApp

We detect WhatsApp on 1,028,368 domains, including Mahindra & Mahindra, Santander Consumer USA Inc., Itau Unibanco Holding SA. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Retail (7.08%).

We detect 1,028,368 domains running WhatsApp across our monthly crawl of live business domains. Company data could be matched for 674,038 of them (65.5%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 101,201 domains carried a WhatsApp detection previously and no longer do.

WhatsApp holds 34.91% of the SMS Marketing category, ranking #1. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to WhatsApp include Re:amaze (8.8% market share), Tawk.to (6.31% market share), Joinchat (5.79% market share), OpenAI (5.62% market share) — measured as a share of the domains we detect running a platform in this category.

Brazil leads with 213,646 matched WhatsApp domains, followed by India (66,386), Spain (43,341), Mexico (25,097), Colombia (22,026). These are counts within the 674,038 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 60.7% of the WhatsApp domains we could match to a company record and size — a subset of 674,038 matched companies, not of all 1,028,368 detected domains. This is followed by 11-50 employees (24.61%) and 51-200 employees (9.54%).

Among the WhatsApp domains we could match to a company with a known founding date, most were founded in the 2010s (41.43%), followed by the 2020s (20.58%). That matched subset is drawn from 674,038 companies and is not representative of all 1,028,368 detected domains. This suggests WhatsApp is most popular among relatively young companies.

The ideal WhatsApp customer is: Company Size: 1-10 employees, Location: Brazil, India, or US, City: Sao Paulo, Mumbai, New York, Madrid, Founded: 2010-2019, Company Age: ~5-15 years old — based on our analysis of 674,038 enriched companies at TechnologyChecker.io.

Major companies using WhatsApp Business include Deloitte, IBM, Samsung, DHL, Starbucks, HSBC, and Allianz. WhatsApp's own published success stories feature Decathlon, easyJet, and Allianz as case study partners. Based on our detection data at TechnologyChecker.io. 1,028,368 domains have WhatsApp integrations, spanning industries from retail and banking to healthcare, logistics, and real estate.

The WhatsApp Business app is free. The Business API uses per-message pricing that varies by country and message category (marketing, utility, authentication, service). Starting July 2025, Meta shifted to message-based billing instead of conversation-based. First 1,000 service conversations per month are free. Actual costs depend on volume, message type, and recipient country code.

Yes, especially outside the United States. Based on our analysis of 674,038 enriched companies at TechnologyChecker.io, 1,028,368 websites integrate WhatsApp widgets, with Brazil (213,646 domains), India (66,386) and Spain (43,341) leading adoption. WhatsApp Business supports broadcast messages, catalogs, and automated replies. The platform's 3 billion monthly users make it the default customer communication channel in Latin America, South Asia, and parts of Europe.

About a third of US adults use WhatsApp, per Pew Research (2025). That's up from 23% in 2021. In our TechnologyChecker.io data, the United States does not appear in the top four markets at all — Brazil (213,646), India (66,386), Spain (43,341) and Mexico (25,097) lead. American businesses still prefer SMS and iMessage for domestic communication.

Brazil leads by a wide margin with 213,646 WhatsApp integrations detected by TechnologyChecker.io, followed by India (66,386), Spain (43,341) and Mexico (25,097), based on our analysis of 674,038 enriched companies. Latin American countries (Brazil, Mexico, Argentina, Colombia) collectively account for over 40% of the base. This reflects WhatsApp's consumer dominance translating directly into business usage.

WhatsApp is the consumer messaging app with 3 billion users. WhatsApp Business is a separate app for small businesses that adds product catalogs, automated greetings, quick replies, and business profiles. The WhatsApp Business API (Cloud or On-Premises) is a third tier for mid-to-large companies that need programmatic messaging, chatbots, and CRM integration at scale.

Retail leads at 7.08% of WhatsApp-integrated companies, followed by Real Estate (3.58%) and IT Services and IT Consulting (3.21%), based on our analysis of 674,038 enriched companies at TechnologyChecker.io. The distribution is unusually flat. No single industry exceeds 8%. Healthcare (2.6%), Construction (2.4%), and Business Consulting (2.7%) all show meaningful adoption, making WhatsApp one of the most horizontal tools we track.

It depends on your audience's geography. SMS works best in the US and Canada where carrier-based texting dominates. WhatsApp is the clear choice for Brazil, India, Spain, Mexico, and most of Latin America and Europe. Based on our migration data at TechnologyChecker.io, businesses increasingly use both: 590 companies added Shopify SMS Marketing alongside WhatsApp in the last 3 years rather than replacing one with the other.

Micro-businesses dominate WhatsApp's web integration footprint. Based on our analysis of 674,038 enriched companies at TechnologyChecker.io, 60.7% have 1-10 employees. Enterprise adoption is real, though: 345 companies with 10,001+ employees use WhatsApp integrations, including Deloitte, IBM, Samsung, Oracle, HSBC, and DHL. The WhatsApp Business API makes enterprise-scale messaging possible.

Brands use WhatsApp for pre-sale consultations via click-to-chat widgets, automated product catalogs, cart recovery notifications, and post-purchase customer support. Our TechnologyChecker.io data shows 1,028,368 websites embed WhatsApp integrations for these purposes. Success stories published by Meta feature brands like Estee Lauder and Absolut Vodka using WhatsApp for promotional campaigns, product launches, and interactive customer experiences.

Yes, both the WhatsApp Business app and Business API are available in the US. However, adoption lags behind other regions. The US does not reach WhatsApp's top four markets in our data, where Brazil leads with 213,646 domains. American businesses face a fragmented messaging market where iMessage, SMS, and social media DMs compete for consumer attention alongside WhatsApp.

Not entirely, but WhatsApp complements email well. WhatsApp messages have reported open rates above 90%, far exceeding email's 20-25% average. However, WhatsApp's per-message pricing for marketing templates, stricter opt-in requirements, and character limitations make it better suited for high-intent, targeted messages. Most businesses in our dataset use WhatsApp alongside email tools, not instead of them.

Starting January 15, 2026, WhatsApp banned general-purpose AI chatbots on its Business API, requiring all AI interactions to be purpose-built and clearly labeled. India also mandated SIM binding for WhatsApp accounts starting March 1, 2026. These changes affect how businesses deploy automated messaging and may require companies to restructure their WhatsApp chatbot implementations.

WhatsApp integrations are detected by scanning website source code for WhatsApp API endpoints, wa.me links, click-to-chat widget scripts, and WhatsApp Business SDK references. TechnologyChecker.io scans 50M+ domains monthly for these patterns. You can also manually check by looking for floating WhatsApp chat buttons, wa.me links in the page source, or WhatsApp-specific meta tags.

Within live chat the nearest alternatives by size are Re:amaze (259,316 domains), Tawk.to (185,769) and joinchat (170,568). For broader business messaging, platforms like Telegram Business, Facebook Messenger for Business, and dedicated tools like Intercom or Zendesk offer different capabilities. The right choice depends on your audience's preferred messaging channel and geographic location.
