A weekly read on where UC, CX and CPaaS demand is heating and cooling, built from real search behaviour.
The heat is in CX. Buyers have re-languaged the contact centre around agents, and search for 'AI agents' now sits near its yearly high. UC demand runs through vendor products, not the category words. CPaaS still belongs to Twilio, and the part that is warming is developer language. Across all three, the acronyms the industry loves, UCaaS, CCaaS and CPaaS, are close to invisible in what buyers actually type.
Buyer-Intent Heat Index: Key Takeaways
CX is the hot pillar. Search for 'AI agents' leads all CX language and has roughly tripled over six months.
'Chatbot' is fading and 'conversational AI' is effectively dead as buyer search terms.
In UC, the category words are near-invisible. RingCentral leads vendor search, and Zoom Workplace mostly reflects meetings usage rather than buying intent.
CPaaS is a one-name category. Twilio holds around ten times the search interest of the pure-plays.
The acronyms UCaaS, CCaaS and CPaaS barely register in what buyers actually type.
The figures below are relative search interest from Google Trends, worldwide, over the past twelve months. They show direction, not volume, and the most recent week or two is held back because Google under-reports it.
CX: Hot on Agent Language
'AI agents' has overtaken 'chatbot' and leads every framing in this space, up roughly three times over six months, though it has flattened in the last month just off its peak. Amazon Connect owns the direct vendor search. Most other tier-one CCaaS brands stay quiet, because buyers look for the category or the suite, not the product name.
AI agents: 92. Hot, now plateauing.
Chatbot: 52. Steady, but overtaken by AI agents in October 2025.
Agentic AI: 38. Warming, roughly doubled over six months.
Conversational AI: 7. Cold, a label buyers rarely type.
Vendor share of search:
Amazon Connect: 57. Found later, through developer documentation.
Genesys: 45. Reference only, its search is heavy with unrelated gaming interest.
Avaya: 21. News-driven rather than fresh evaluation.
Five9: 12, and Talkdesk: 5. Both surface in bake-offs.
NiCE CXone: 3. Appears in consideration sets.
UC: The Category Is Invisible, the Vendors Are Not
'Unified communications' and 'UCaaS' sit near the floor. The vendor names carry the demand, led by RingCentral. This week the pillar tracks Zoom Workplace rather than 'Zoom Phone', because 'Zoom Phone' as a search term is muddied by smartphone camera zoom. Even then, Zoom Workplace mostly reflects existing meetings usage, not UC evaluation.
RingCentral: 32. The UC search leader, found through reviews.
Avaya: 21, news-driven. Vonage: 17, found through reviews.
Zoom Workplace: 16. Broad meetings usage, not UC evaluation. It replaces Zoom Phone, which is muddied by smartphone camera searches.
Mitel: 12. Reviews and head-to-heads against Nextiva, Avaya and RingCentral.
Microsoft Teams Phone: 11, an undercount since most demand hides inside general Teams search. Dialpad: 9. Nextiva: 6.
CPaaS: A One-Name Category
Twilio holds roughly six times the interest of the next vendor and ten times the pure-plays. The 'CPaaS' label is effectively dead, so the useful signal is developer language. 'Communications API' and 'messaging API' have both roughly tripled over the year.
Twilio: 61. Dominant, and developer-led.
Vonage: 10, Sinch: 6, Telnyx: 5, Infobip: 4.
MessageBird: 2, pulling 'whatsapp business api'. Plivo: 2.
Where the Search Sits by Region
This is search intensity relative to each country's own activity, so it over-weights smaller markets and reads as direction, not budget. Agent language runs hottest in APAC, with Japan, South Korea, Hong Kong, Taiwan, India and Singapore recurring. The established platforms track the mature Western markets, with Amazon Connect strongest in the US, UK and Ireland. The short version: search intensity leans APAC and emerging markets, while buying power leans US, then EU and UK.
So What, Now What
The market's language has moved to agents. Lead with that where you can defend it, bid the plain words rather than the acronyms, and watch the Talkdesk to Five9 and Nextiva to RingCentral comparisons for live bake-offs. Search is a leading signal, not a revenue forecast, and it is read here as direction, not certainty.
Frequently Asked Questions
Which CX and contact centre vendors lead search interest right now?
Amazon Connect leads direct vendor search in CX, with Genesys second when measured on its company entity rather than the contaminated brand term. Most other tier-one CCaaS names stay quiet, because buyers search the category or the suite, not the product. The bigger shift is in language: 'AI agents' has overtaken 'chatbot' as the dominant framing.
Where is unified communications (UC) buyer intent concentrated?
UC search runs through vendor names, not the category. RingCentral leads what buyers actually search, ahead of Avaya, 8x8 and Vonage, while 'unified communications' and 'UCaaS' sit near the floor. Geographically the demand is US-dominated, and most of the non-US signal is offshore contact-centre workforce in the Philippines and Pakistan rather than European buyers.
Who leads CPaaS, and is the category term worth targeting?
Twilio owns CPaaS in search, holding roughly six times the interest of the next vendor. The label 'CPaaS' is effectively dead as a search term, so the real signal is developer language: 'communications API' and 'messaging API' have both roughly tripled over the year. Demand is developer-global, peaking in Singapore and across emerging markets, with the US only mid-pack.
Is Google Trends a reliable buyer-intent signal?
It is a leading signal, not a revenue forecast. Trends shows relative search interest on a 0 to 100 scale, not absolute volume, and it reads the top of the buying journey, problem, solution and shortlist intent, best. Its value is spotting where demand and language move before it reaches pipeline.
How often is the Buyer-Intent Heat Index updated?
Weekly. It is rebuilt every Monday from fresh Google Trends data over a rolling twelve-month window, worldwide, across UC, CX and CPaaS.
Source: Google Trends, worldwide, rolling twelve months, read on 16 July 2026. Figures are relative search interest, not volume.
This is the kind of read I produce for CX, UC and CPaaS vendors trying to see where buyer demand is moving before it shows up in a board deck. If you'd like this on your own category and competitive set, get in touch.
