Salesforce To Acquire Cresta, Betting on Voice AI as the Future of CX

Today, Salesforce announced it has signed a definitive agreement to buy Cresta, with the deal expected to close in FY 2028. Although the terms of the deal have not been made public, it’s clear Salesforce was highly motivated by the intelligent AI operating platform's voice agents, capable of completing complex customer calls end-to-end and providing real-time live agent coaching.

With Cresta bringing conversational insight and voice AI to Salesforce's existing CRM and "work around the work" systems, the goal is to eliminate data silos. 

Voice is where service is hardest to get right, and where it matters most to customers. Cresta has built voice agents that handle complex, high-volume calls for some of the world’s largest brands. As more service is resolved in the conversation itself, together we’ll bring the customer, the conversation and the outcome into one place.

Analyst Take 

Cresta, founded out of the Stanford AI Lab in 2017, gives Salesforce a proven enterprise voice platform: in April 2026, Cresta passed $100 million in ARR. 

Given that Cresta was mostly sold as a premium add-on to enterprise CX solutions like NiCE CXone, Genesys Cloud, and, Five9, its model has likely come under increasing pressure as those same vendors add coaching and AI agents to their own products. 

While the announcement's exact timing was unknown, at least in my view, an acquisition was always an inevitability for Cresta. 

Cresta is Salesforce's tenth acquisition agreement of 2026. Fin (formerly Intercom) closed on September 10 for $3.6 billion. Salesforce's October 10 announcement of a definitive agreement to acquire Braze followed. Less than a week ago, Salesforce also announced a definitive agreement to acquire Rune Technologies.  

It has to be said that the Cresta news arrives as Salesforce tries to close the gap between how its business is performing and how investors value it. 

The good: Salesforce's Q2 FY27 results saw revenue grow 11% to $11.35 million, Agentforce passed $1.5 billion in ARR, and Salesforce raised its full-year forecast to $46.1-$46.4 billion. 

The complication: investors aren't as convinced. Salesforce shares fell roughlhy 41% in the first half 0f 2026, and the stock bottomed out at $146 in June (it's recovered to roughly $225 as of this writng. 

Salesforce's answer to investor anxiety about AI agents shrinking demand for per-user liscensing (Salesforce's bread-and-butter) is, clearly, to buy the AI agents themselves: hence the Cresta acquisition.

CX Impact 

Consolidation has been the name of the CX game for the past two years. NiCE bought Cognigy, Thoma Bravo took Verint private, SoundHound's LivePerson deal closed, and Genesys acquired Pinkfish. 

Voice remains the top prize as the most popular, highest-stakes customer interaction channel. A tool like Cresta, which offers autonomous agentic Voice AI that resolves issues without a human, gives Salesforce a serious leg up. 

While most of the consolidation we've seen is about contact centers acquiring AI, Salesforce's Cresta acquisition means a CRM vendor has bought the conversational layer while leaving the telephony to others. This, of course, is a notable pivot from Salesforce's Agentforce Contact Center -- and keeping Cresta platform-agnostic concedes that large enterprises will likely not rip out Genesys or NiCE to get AI. 

With the Cresta acquisition, Salesforce seems to think owning the conversation, not the phone line, is the durable CX position in the long term.
