Companies Using CallTrackingMetrics

I've spent more than ten years building web crawling and technographic systems. CallTrackingMetrics, which now trades as CTM, is the clearest case in call tracking of two vendors chasing one buyer. Our October 2026 crawl finds it on 25,011 live domains, with 17,102 matched to a company, and it now ranks second in the category. Below I use that set, the exits we've logged since March 2026, a browser check of the 50 companies in the table, CTM's own pricing and company pages, and the G2 review counts on this page.

Growth trajectory

The chart runs from 15,274 domains in June to 25,011 in October, then flattens: 481 domains added in October after 2,968 in September. Don't read the climb as a sales surge. The set of domains we crawl turns over every month, with dead sites dropping out and new ones coming in, and our detection widens over time, so part of each step is coverage. CallRail's line has the same shape over the same months, which is what you'd expect if much of the movement is ours. The rank change is real but thin: CTM sits 269 domains ahead of Invoca.

"Second place in call tracking is a 269-domain lead over Invoca. I'd call that a tie and expect it to change hands more than once." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker

Sales Signal: The installed base is steady enough to prospect as a list. Don't build a pitch on CTM growing fast; build it on who the customers are and what they run next to it.

Customer profile

The size curve is close to a copy of CallRail's. 50.63% of matched companies have 1 to 10 staff against CallRail's 50.4%, and 84.86% have 50 or fewer. Age lines up too, with 9.86% founded in the 2020s. At the top of the list the buyers are health systems and national service brands, and several health systems run one CTM account across member hospitals: Beth Israel Lahey Health and Beth Israel Deaconess load the same one, as do UMass Memorial Health and Milford Regional, and Memorial Healthcare System and Joe DiMaggio Children's Hospital. Edward Jones, Morgan & Morgan and Two Men and a Truck run it on their main sites. CTM doesn't publish a customer list we could cross-check, so these names come from our own browser check.

Sales Signal: Any segment that qualifies a CallRail account qualifies a CTM one. Build one definition and run it against both lists; the difference shows up in industry, not in size.

Industry and geographic concentration

Construction leads at 12.26%, then medical practices (9.19%) and hospitals (6.28%). The CTM-specific rows come next. Mental Health Care is 4.49%, a label that doesn't reach CallRail's top ten, and Wellness and Fitness Services adds 2.53%. Across three labels, health care comes to 19.96%. Law is the gap, with Law Practice at 3.52% here against 7.7% on CallRail's list.

Geographically CTM is still a North American product, with 14,069 US and 1,537 Canadian companies. But the UK holds 4.82% of the companies we could place, against CallRail's 1.81%, and Israel (112) and South Africa (80) both appear.

Sales Signal: Lead with behavioural health and multi-site health systems, where CTM is relatively strongest. In the UK the two vendors have similar absolute counts, 812 CTM companies to CallRail's 961, so British prospecting should work both lists.

Overlap and switching

Earlier versions of this page reported switching between CTM and CallRail. I've removed it. Our test calls it switching only when at most 40% of the domains that ever ran both products still run both, and for this pair the figure is 80%, 1,285 of 1,606. With Invoca it's 72.4% (71 of 98), with Marchex 81.9% (68 of 83). Of the 3,441 domains that dropped CTM since March, 166 run CallRail, 12 Invoca, 10 Patient Prism and 3 each WildJar and Marchex. That's 194, about one in eighteen. In the other direction, 85 domains that dropped CallRail and 8 that dropped Marchex run CTM.

"When 1,285 sites pay for CallRail and CTM at the same time, the real contest is which script survives the next website rebuild." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker

Sales Signal: The 1,285 dual-tracker domains are the live opportunity for either vendor, a consolidation pitch with an obvious saving. Pure displacement has a small pool: 166 domains in seven months on the busiest route.

Technology ecosystem

Across the 25,430 live CTM domains our stack figures use, Google Analytics runs on 95.64% and WordPress on 55.09%, below CallRail's 63.43%. The builder rows explain part of that. FloorForce is on 5.17%: it's a website and ad platform that says it works with more than 2,000 flooring retailers, and it barely appears on CallRail sites. That looks like an agency channel, one marketing firm putting CTM on its clients' sites. Drupal sits on 3.79%. Gravity Forms (12.71%) and Contact Form 7 (12.06%) handle forms, and reCAPTCHA is on 28.96%.

Sales Signal: Find the agencies. CTM's Marketing Pro plan includes sub-accounts and white label, and FloorForce's footprint shows how much one agency can add. Agencies that resell CTM are a channel for anything sold to local retailers and clinics.

G2 review signals

The G2 summary on this page counts 199 mentions across five positives, and three of them are about people: customer support (49), customer service (43), and support again alongside the interface (28). The five complaints total 80, and four describe the same problem, a steep learning curve and hard-to-navigate reports, with 68 mentions between them. That fits what CTM sells. Its plans stack contact-centre features (softphone, dialer, skills-based routing) on top of attribution, and a deeper product takes longer to learn. Our data points the same way: a base where 84.86% of companies have 50 staff or fewer rarely has a dedicated admin.

Sales Signal: Training and setup services sell into this base. CTM's pricing page includes up to 20 hours a year of professional services only on Enterprise, so smaller accounts have to find that help elsewhere.

Key takeaways

1. CTM holds 12.86% of Call Tracking and ranks second, 269 domains ahead of Invoca.
2. Its buyer is CallRail's buyer: small North American service firms with near-identical size and age curves.
3. It leans further into health care, 19.96% across three labels, and especially behavioural health.
4. Agencies matter. FloorForce alone accounts for 5.17% of CTM domains.
5. Rivals overlap with it far more than they replace it: 1,285 sites run CTM and CallRail together.

Sales applications

Outreach angle: "You run CTM, and probably more of it than you use. Who on your team owns the reports?" It speaks to the learning-curve complaint that leads CTM's G2 cons.

Targeting strategy: filter to Mental Health Care, Medical Practices and Hospitals and Health Care. That's 2,852 matched companies, about one in five of those with a known industry.

Competitive angle: start with the 1,285 domains running CTM and CallRail together, and ask which one they'd keep.

Every detection figure here comes from our crawl: 25,011 CTM domains and 17,102 matched companies as of October 2026. Our write-up on technology detection methods explains how we find scripts like this one.
