The CP 20 is back, and this latest installment focuses on communications platform as a service (CPaaS), which is going mainstream, expanding beyond the core base of digital native companies, startups and developers, and into the enterprise segment.


451 Research’s Raul Castanon

CPaaS is a cloud-based platform that allows developers to add real-time communications features to their own applications without needing to build back-end infrastructure and interfaces.

The competitive landscape is changing rapidly, fueled by emerging providers now targeting the mainstream enterprise segment, as well as increasing M&A, which is allowing unified communications (UC) providers to expand their capabilities to CPaaS.

According to IDC, the global CPaaS market is expected to grow from $2 billion in 2017 to nearly $11 billion in 2022. CPaaS will continue to accelerate at a compound annual growth rate (CAGR) of 39.2% through 2022, it said.

Raul Castanon, 451 Research’s senior analyst of workforce collaboration, said M&A activity has spiked in the last two years, significantly influencing the competitive landscape, with seven CPaaS-related deals so far this year and a total of 14 last year, according to 451 Research’s M&A KnowledgeBase.

“Cloud communications providers – including UC and contact center providers – are expanding into CPaaS with vendors such as 8×8, Sangoma and Voyant, following the lead of Vonage by targeting standalone CPaaS vendors,” he said. “These add to a growing number of vendors with CPaaS capabilities which includes vendors like Avaya, Alcatel-Lucent Enterprise and Mitel.”

Tim Basa, AppSmart‘s vice president of sales, said “we’re in a CPaaS hype cycle to be sure.”

“Many providers have sprung up to take advantage of API-driven environments,” he said. “What’s really interesting is that companies that were virtually unknown 24 months ago, Twillio [IPO in 2016], Nexmo [aquired by Vonage], for example, are top of mind in many circles today. Also, niche players like ZipWhip and MessageBird are interesting.”

Michael Brandenburg, industry analyst at Frost and Sullivan, said he can’t think of a market that’s been more M&A hungry.

UCaaS, and even SIP trunking companies, have merged over the years, and CPaaS is the next frontier,” he said. “8×8-Wavecell is really the acknowledgement of the need for programmability within all business phone numbers. Vonage’s acquisition of Nexmo really set the tone for what a lot of the UCaaS providers are looking at how to respond to that. They’ve really rebooted what it meant to be a UCaaS provider in adding that API layer, and then going through the effort of retooling their UCaaS solution to release an application on top of that. That programmable platform in my mind has really changed the game that’s visionary.”

Based on feedback from analysts and industry experts, recent news reports and the 2019 Frost and Sullivan CPaaS Radar Report, we’ve compiled a list, in alphabetical order, of 20 CPaaS providers that are making the most of the current competitive landscape and charting success. The list offers a mix of well-known providers as well as lesser-known companies that are making big strides in CPaaS.


2600Hz-logo-300x73.pngCastanon said 2600Hz is a standalone CPaaS provider worth keeping an eye on. It offers a white label, multitenant cloud-based telephony platform designed to simplify how businesses sell, deliver and manage communication services.


8x8-300x144.pngBrandenburg said Wavecell gives 8×8 a “jump-start into the CPaaS space.” 8×8 acquired the Singapore-based CPaaS provider for about $125 million in cash and stock. The purchase gives 8×8 an entry into the global CPaaS market, and is an expansion of its cloud business from UCaaS and CCaaS.

Alcatel-Lucent Enterprise

ATT-logo_300-pixels-wide-300x105.jpgBrandenburg said AT&T jumped into CPaaS this year with its partnership with Ribbon Communications.

“It’s amazing to think of AT&T as a new entrant into the market – into any market – but they launched earlier this year and there’s some definite early interest, and we’re going to hear more about that soon,” he said. “But the fact that they kind of decided to partner for a platform and then build on it, rather than trying to take the years or even longer for a tier 1 carrier to build that kind of solution in house, is pretty telling in the space.”

Avaya-300x86.pngBrandenburg said Avaya is “very interesting” in CPaaS. Formerly Zang, Avaya’s OneCloud CPaaS is a public cloud service that offers APIs and applications as a service for communications and collaboration.

“Looking forward, the ability to address the requirements of the enterprise segment will be critical for success,” Castanon said. “This is not an easy task, and will require developing and training a strong channel partner network, who play a critical role for sales and marketing. Targeting the enterprise will also require that vendors carefully articulate their value proposition in terms of the business problems that enterprises are looking to address.”


Bandwidth-logo-300x63.pngBrandenburg said “we’re definitely in a market where the pie is getting bigger,” and Bandwidth is among providers that have distinguishing characteristics.

“Bandwidth is an emerging provider now targeting the mainstream enterprise segment,” Castanon said.

Brightlink-logo-300x75.pngBrightlink also is an emerging provider now targeting mainstream enterprises, and it recently announced a major update that bolstered its communications, Castonon said. Last month, Brightlink said it has seen a surge in demand for its CPaaS offering since launching its 2.0 platform in May.


Freespee-300x78.pngAn interesting emerging player in CPaaS is Freespee, a private company founded in 2009, Castanon said. Its CPaaS platform is designed as a comprehensive conversation cloud that enables consumers to talk to brands in real time, he said.

IntelePeer logo 2019Brandenburg said IntelePeer stands out and is among providers with distinguishing characteristics.

“IntelePeer is positioned as a CPaaS 2.0 vendor, targeting enterprise use cases,” Castanon said.


Kaleyra-logo.pngCastanon said Kaleyra is an emerging provider now targeting mainstream enterprises, and is making headway with finance and banking use cases. Through its platform, Kaleyra manages multichannel integrated communication services on a global scale, comprising messages, push notifications, email, instant messaging, voice services and virtual assistants.

MessageBird-300x168.pngCastanon said MessageBird is a standalone CPaaS provider “worth keeping an eye on,” and Basa said it’s an “interesting niche player.” More than 15,000 global customers use MessageBird to solve their communication challenges by routing important messages and calls on their behalf.

Mitel-300x71.pngCastanon cited Mitel is a noteworthy vendor with CPaaS capabilities.

“A successful CPaaS provider must deliver on the expectations they set for the end-user client,” Basa said. “There’s a lot of hype and bold promises in the space. Sometimes clients feel like they are sold products and services that are not proven, or vetted thoroughly prior to the sale and implementation. Execution, customer experience and delivering desired outcomes will lead to success.”

Nextiva-logo-small-300x95.pngAt this month’s Nextiva NextCon 2019, Carl Katz, Nextiva’s vice president of channel sales for North America, said CPaaS is the “newer technology allowing us to create solutions on one pane of glass without integrations, and keeping the customer stickier and solidifying the partner annuity for the long term.”

“It’s a critical time right now for our partners, our customers and suppliers to come out with this kind of solution in order to change the conversation and really find that solution for customers,” he said. “We are differentiating ourselves because no one else has this unique technology and this insight with their customers, our customers’ customers, utilizing this business analytics and intelligence to give [partners] insight into their customers’ satisfaction and journey.”

Plivo-300x158.pngCastanon said Plivo is a standalone CPaaS provider worth keeping an eye on. Plivo’s infrastructure handles billions of voice calls and messages every year from businesses globally. More than 70,000 customers use Plivo to add voice calling and messaging capabilities to their web, mobile and desktop apps.

Ribbon Communications

Ribbon-Communications-logo-300x158.pngBrandenburg said Ribbon Communications is enabling service providers of all types.

“There’s a pretty clear set of use cases today for developers and startups of why you would go with a CPaaS, and I think those are firming up in terms of the enterprise,” he said. “At the same time, the blessing of it is CPaaS can be you can do anything you want to do with an API [in] a CPaaS platform. It’s up to the enterprise to figure out exactly what they need.”

Telestax-logo-300x55.pngBrandenburg said Telestax, a Cisco solution partner, is doing some really interesting things enabling service providers at the tier 2 and 3 levels. Last week, Telestax announced enhancements to Message Exchange, its CPaaS solution for enabling text messages. Message Exchange now allows the sending and receiving of texts for Cisco Webex Teams. The company also unveiled new APIs for Cisco UC-One and an upgrade to the Telestax UC-One API console.

ThinQ-logo.pngBrandenburg said another provider that’s emerging in CPaaS is thinQ.

“By offering wholesale voice and messaging pricing, thinQ’s greatest strengths are cost savings, scale and support for partners of all sizes,” according to Frost and Sullivan’s CPaaS Radar Report. The company’s solution ensures that voice carriers, VoIP providers and enterprise firms can fully control their direct inward dialing numbers ordering and provisioning, as well as researching call quality issues without the need for opening help desk tickets.

Tropo-logo.pngBasa said Tropo, backed by Cisco, will continue to grow and take advantage of the Cisco clout and engineering knowledge. Tropo provides a cloud API platform that enables customers and developers to embed real-time communications within their applications.

Twilio-logo.pngThe de facto CPaaS market leader, Twilio earned its spot largely based on a strong record of innovation, Castanon said. It invests heavily in R&D, consistently raising the bar with a comprehensive and innovative portfolio. It almost singlehandedly created and defined the industry, but the landscape has changed significantly in the last two years, he said.

Twilio is definitely turning its focus to include large enterprises and “they’re getting some marquee customers there,” Brandenburg said.

Vonage-logo-2019.jpegVonage is “absolutely bringing a new vision to both what it means to be a CPaaS and platform provider,” incorporating its UCaaS and CCaaS with those applications on top of the platform, Brandenburg said.

Basa said Vonage, with Nexmo, is “certainly among the most proven in the space.”
