Salesforce Agrees to Buy Cresta, Maker of Call Centre Voice Agents

Salesforce has signed a definitive agreement to buy Cresta, a company whose AI voice agents answer complex customer calls for brands including Marriott, Comcast and Alaska Airlines. The Salesforce Cresta announcement on 2 November did not disclose terms. The Information reported the price at $2.7bn, a figure neither company has confirmed.

The deal is about the phone line, the part of customer service that chatbots have found hardest to automate. Salesforce already owns the customer record through Service Cloud and its Agentforce agents; Cresta brings software that can hold a live spoken conversation, coach human agents while they talk, and analyse every call afterwards.

What Cresta adds to Service Cloud

Salesforce describes Cresta as “the voice-first operating system for customer experience” and says its voice agents “resolve complex customer calls end to end”. According to Salesforce, they handle interruptions and natural real-time conversation at enterprise scale. The same platform guides human representatives during calls, tests and improves voice agents, and holds both to the same quality standard.

Kishan Chetan, who runs Agentforce and Service Cloud at Salesforce, said: “Voice is where service is hardest to get right, and where it matters most to customers.” Cresta chief executive Ping Wu, who also announced the deal on LinkedIn, said that “by uniting our platform with Salesforce, we will realize our full vision at scale”.

Salesforce also said that after closing, “Cresta will continue to support the leading contact center and telephony platforms its customers rely on today.” That is a notable promise for existing Cresta customers that run other systems.

Another deal in a busy year for Salesforce M&A

Cresta is the latest in a run of Salesforce acquisitions covered by TSN. Last month it agreed to buy Braze for about $5.66bn to bolster Marketing Cloud, signed a deal for AI analytics platform Loops to fold into Tableau, and agreed to buy Rune, maker of AI military logistics software. In late October it announced agent evaluations and spending caps for Agent Fabric, its tooling for managing AI agents.

The transaction is expected to close in the first quarter of Salesforce’s fiscal year 2028, “subject to customary closing conditions, including receipt of required regulatory approvals.”

Why the Salesforce Cresta deal targets the phone, not the chat window

Text chat and email have been the easy wins for AI in customer service. Voice is harder: callers interrupt, change their minds, and usually ring about the problems that matter most to them, such as a cancelled flight or a billing dispute. The case for buying rather than building is that Cresta, by Salesforce’s account, already runs at scale for large brands. That gives Salesforce a working product, not a roadmap.

The more strategic angle is data. Salesforce’s own statement frames the problem as conversations “trapped in silos” and disconnected from the customer record. If every call, whether handled by an AI or a person, feeds straight into the CRM, Salesforce strengthens its hold on the whole service workflow. That is also why the promise to keep supporting rival contact-centre and telephony platforms matters: customers will watch whether that support continues once integration work begins.

For compliance teams, voice agents raise their own questions. Recorded and analysed calls involve personal data, and in regulated sectors such as banking and insurance the call itself can be evidence of what a customer was told. Firms in the UK and EU using such tools will need clear records of when a caller is speaking to an AI, how transcripts are stored and how automated decisions can be challenged. None of that is specific to this deal, but consolidation puts more of those obligations on fewer vendors.

The price is also worth keeping in proportion. The reported $2.7bn is unconfirmed, and regulators have yet to review the deal. The next marker is any filing or regulatory notice ahead of the expected close in Salesforce’s first fiscal quarter of 2028.
