Companies Using OneSignal

With over a decade of experience in web crawling and technographic data analysis, I've reviewed OneSignal's adoption across 46,835 active domains and 19,783 enriched company profiles matched to LinkedIn data. OneSignal raised $50M in Series C funding from BAM Elevate in 2022, bringing total financing to over $80M. This analysis covers customer demographics, deployment patterns, and stack composition as of our August 2026 crawl. For category context, see our MarTech statistics overview.

1. What the trend line shows, and what it does not

Our current-crawl series runs 36,618 (June) → 45,564 (July) → 46,835 (August 2026). I am not going to call that growth. The whole corpus expanded 17.9% between June and July as our crawler resolved more subdomains, and 37.2% of the OneSignal domains we first saw in the last 30 days are subdomains against 4.5% of the domains we already knew about. The line moved because we looked in more places.

What the window does measure honestly is churn. 6,066 domains have dropped OneSignal since we began tracking it in March 2026, roughly 13% of the active base. That is normal for a JavaScript SDK — a snippet disappears the moment someone redeploys without it — and it is worth contrasting with the DNS-detected platforms in our corpus, where a stale record can sit on a domain for years after the contract ends.

Sales Signal: This is a maturing platform, not a declining one. Companies running OneSignal since 2017-2019 are embedded and will not churn easily. Position around expansion, not replacement.

2. The deployment pattern nobody documents

The single most useful thing in this dataset is not the count, it is the subdomain. 16 of our top 50 detections are careers and recruitment portals: cityjobs.nyc.gov, careers.soprasteria.com, careers.iconplc.com, careers.drreddys.com, boots.jobs, jobs.greeneking.co.uk, admiraljobs.co.uk, harrodscareers.com, careers.legalandgeneral.com, aldicareers.com.au. Another 9 are newsrooms, blogs, or podcast sites — stories.inspirebrands.com, blogs.opentext.com, news.sanfordhealth.org, podcast.groupe-casino.fr.

"Large employers are using push notifications to tell candidates a job opened. It is not in OneSignal's marketing, it is not in any case study I can find, and it is a third of their enterprise footprint." - Mehmet Suleyman, CEO at TechnologyChecker.io

This also explains the low LinkedIn match rate on this profile — 42.24%, the lowest in our current refresh cycle. A recruitment subdomain on a separate registrable domain (boots.jobs, harrodscareers.com, aldicareers.com.au) is much harder to attribute to a company record than a corporate homepage.

Sales Signal: The subdomain pattern is the upsell. An organisation running OneSignal on its careers site has one team using it and every other department not using it. That is a far more specific opening than "you use OneSignal".

3. Customer profile

58.43% of OneSignal domains belong to companies with 1-10 employees and 46.85% of enriched companies were founded in the 2010s, with another 19.36% in the 2020s. This platform lives on indie developers and small app teams, and it is a default choice for new projects. The enterprise tail is genuinely small — 91 organisations with 10,001+ employees — but its shape is consistent, and it is the careers-portal pattern above.

Sales Signal: Filter for 11-50 employees founded 2015-2020. That segment is past the startup phase, likely pushing against free-tier limits, and actively deciding whether to upgrade or consolidate.

4. Industry and geographic concentration

No single industry dominates. Technology, Information and Internet leads at just 4.68%, followed by three media verticals: Online Audio and Video Media (4.3%), Newspaper Publishing (4.14%), and Book and Periodical Publishing (4.11%). Media and content businesses collectively account for over 19% of the base. Push is a retention tool and content businesses live on returning audiences, so this is the expected shape.

Geographically OneSignal breaks the usual US-dominated pattern harder than almost anything we track. The United States leads at just 15.84%, followed by India (11.29%) and Brazil (9.81%), with Turkey at 3.26% well above its usual weight in our corpus.

Sales Signal: The India-Brazil-Turkey corridor needs multilingual push support and timezone-aware delivery. A 15.84% US share, against 30-50% for most martech tools, means international expansion services are badly undersold into this base.

5. Why there is no migration section on this page

The previous version of this analysis reported a 2.1:1 net outflow to HubSpot and a 4.8:1 outflow to Brevo. Those numbers were wrong, and it is worth saying why rather than quietly deleting them. They compared OneSignal against a marketing-automation competitor set, and the domains counted as "switching" were mostly running both products the whole time. When we test properly — what share of domains that have ever shown both still show both today — the push-notification rivals come back at 75.7% for PushOwl and 62.6% for Webpushr. A company running OneSignal and PushOwl together is not migrating between them; it has a Shopify app and an SDK doing different jobs.

Sales Signal: The absence of a real corridor is itself the finding. Push notification tooling is additive rather than substitutive, so displacement pitches land badly here. Sell alongside, not against.

6. Technology ecosystem

Google Analytics appears on 79.32% of OneSignal domains, well above the internet-wide average, with Cloudflare Browser Insights at 18.93%. These are teams that measure. The commerce overlap is the number I would not have predicted: WooCommerce at 10.17% but Shopify at only 0.65%. The category leader, PushOwl, is a Shopify-native app — so the two largest products in Push Notifications have almost no overlapping install base at all. They are not really competing. WhatsApp Business Chat on 9.14% is the most common companion messaging channel.

Sales Signal: The analytics-heavy stack signals teams that care about attribution. Tools connecting push engagement to conversion would resonate. Do not pitch Shopify integrations into this base — they are not there.

7. G2 review signals

OneSignal holds 4.7/5 across 1,176 G2 reviews. Ease of use and setup (287 mentions) is the top pro, which aligns with a base that is 58.43% micro-business. Documentation quality (164 mentions) is an unusual strength for a messaging tool. The top criticism is paid-plan gating (89 mentions): the free plan caps segments at 6 and data tags at 2, and Growth starts at $19/month plus $0.012 per mobile MAU, so a company at 50,000 MAU pays around $619/month before email and SMS.

Sales Signal: Companies at 10,000-20,000 subscribers sit at the pricing inflection. Competitors offering a smoother upgrade path can intercept them there.

Key takeaways

1. Market position: #2 of 39 in Push Notifications at 29.73%, behind PushOwl's 54.3%. Everything below #2 is under 3%.
2. The two leaders barely overlap: PushOwl is a Shopify app, OneSignal an SDK, and Shopify appears on just 0.65% of OneSignal domains.
3. Enterprise use is careers portals: 16 of the top 50 detections are recruitment sites. This is the deployment pattern to sell into.
4. Micro-business core: 58.43% have 1-10 employees. Self-serve, bottom-up adoption.
5. Global distribution: US at just 15.84%, with India, Brazil, and Turkey unusually strong.

Sales applications

Outreach template: "Hi [Name], I noticed [Company] runs OneSignal on [subdomain] — we see that pattern a lot on careers and newsroom sites specifically. 79% of OneSignal domains also run Google Analytics, so you're likely already measuring notification impact. Would a quick call make sense to discuss connecting push engagement to [conversion goal]?"

Targeting strategy: Filter for OneSignal + 11-50 employees + founded 2015-2020 on TechnologyChecker.io. For the enterprise list, filter instead on detection subdomains containing careers or jobs, which surfaces a recruitment-marketing segment nobody else is targeting.

Competitive angle: Do not pitch displacement. Push tooling coexists — 75.7% of domains that ever showed both OneSignal and PushOwl still show both. Sell the layer above: attribution, journey orchestration, or channel consolidation.
