The deal brings end-to-end voice agents and real-time rep coaching into Service Cloud. Salesforce did not disclose a price but it has been reported at $2.7 billion.
Salesforce announced Monday that it has signed a definitive agreement to acquire Cresta, a contact center AI company whose voice agents handle customer phone calls from start to finish and whose platform coaches human representatives during live conversations. The announcement arrives less than two weeks after Salesforce agreed to buy Braze and extends a run of customer experience and marketing acquisitions that has defined the company’s 2026.
Salesforce did not disclose financial terms. The Information, citing a person familiar with the deal, reported that Salesforce agreed to pay $2.7 billion. Salesforce has not confirmed that figure.
The transaction is expected to close in the first quarter of Salesforce’s fiscal year 2028, which runs February through April 2027, subject to regulatory approvals and customary closing conditions.
What Cresta brings
Cresta describes itself as a voice-first operating system for customer experience. Its voice agents hold real-time conversations, handle interruptions and resolve complex calls at enterprise scale. The same platform guides human representatives in real time, tests and improves the voice agents, and analyzes every interaction, with the stated goal of holding humans and AI agents to a common quality standard.
Salesforce named Marriott, Comcast and Alaska Airlines among Cresta’s customers.
Founded in 2017, Cresta had raised roughly $276 million from investors including Andreessen Horowitz, Sequoia Capital, Greylock and Tiger Global, according to third-party funding databases. Its last publicly disclosed valuation was $1.6 billion, set by an $80 million Series C in March 2022. A $125 million Series D followed in November 2024 without a publicly announced valuation. If The Information’s reported price is accurate, the sale would represent a meaningful step up from that 2022 mark.
Salesforce’s rationale: the phone call is where service is hardest
Salesforce’s announcement frames the deal around a single channel. Customers call when the stakes are highest, the company argues, and that is where service most needs to go right in the moment.
“Voice is where service is hardest to get right, and where it matters most to customers,” said Kishan Chetan, EVP and GM of Agentforce and Service Cloud at Salesforce. “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.”
The division of labor Salesforce describes is straightforward. Salesforce supplies the customer’s history and the systems of record where work gets done; Cresta supplies the understanding of each conversation and the voice agents able to act on it. Combined with Service Cloud, the company says, businesses will be able to tie every conversation to the outcome it produces, whether resolution, retention or revenue.
Cresta CEO Ping Wu positioned the acquisition as a route to scale. “Now, by uniting our platform with Salesforce, we will realize our full vision at scale, embedding real-time conversation intelligence and agentic experiences directly into Salesforce’s first-class customer service Platform,” Wu said.
A platform-neutral commitment, at least for now
One line in the announcement is likely to draw the closest reading from contact center buyers: after the transaction closes, Cresta will continue to support the leading contact center and telephony platforms its customers rely on today.
That matters because Salesforce does not sell its own contact-center-as-a-service telephony stack. Cresta’s existing customers run on a range of CCaaS and telephony vendors, and the company has historically integrated with Salesforce, Amazon Connect, Five9 and others. CMSWire noted that customers on non-Salesforce telephony will want that neutrality commitment documented and, ideally, attached to a timeline. Salesforce’s announcement does not specify how long the commitment extends.
Where Cresta fits in Salesforce’s 2026 acquisitions
Cresta is the fifth customer experience or marketing technology acquisition Salesforce has announced this year. According to CMSWire’s tally, the others are:
- Contentful, a composable content platform. Agreement signed June 1, closed September 1. Reported at $1.25 billion.
- Fin (formerly Intercom), an AI customer service agent. Agreement signed June 15, closed in September. About $3.6 billion.
- Listen Labs, an AI customer research and simulation platform. Agreement signed September 29. About $2 billion, as reported by Business Insider.
- Braze, a customer engagement platform. Agreement signed October 20. About $5.66 billion enterprise value.
- Cresta, voice AI agents, real-time coaching and conversation intelligence. Agreement signed November 2. Price not disclosed; reported at $2.7 billion by The Information.
CMSWire put the disclosed and reported totals for the first four at roughly $12 billion before Cresta. Salesforce’s newsroom also lists 2026 agreements for m3ter, Loops and defense AI company Rune Technologies.
With Fin and Cresta, Salesforce will own a text-first service agent and a voice-first one. How the two are brought together inside Agentforce and Service Cloud, whether as a single agent platform with two front doors or as adjacent products, is a question the announcement leaves open.
What this means for enterprise marketing and CX leaders
For marketing and CX executives, the Cresta deal matters less as a contact center story than as a signal about where Salesforce intends the customer record to live and what it expects to flow into it.
Voice conversations become first-class customer data. Salesforce’s stated goal is to connect every call to the customer’s history and to a measurable outcome. If that integration lands as described, the insights generated on the phone, including intent, sentiment and resolution, become available to the same Customer 360 that marketing, sales and service already work from. Organizations that have treated call recordings and contact center analytics as a separate silo may find that the boundary erodes faster than planned.
The service-to-marketing feedback loop tightens. Salesforce’s acquisitions this year span content (Contentful), engagement (Braze), research (Listen Labs), digital service (Fin) and now voice service (Cresta). Taken together, they outline a stack in which the conversation a customer has with a service agent can inform the next message that customer receives. Marketing leaders should expect that connection to be a selling point in forthcoming roadmap conversations.
Platform consolidation raises governance questions. Enterprises running Cresta on non-Salesforce telephony, or running Salesforce alongside other contact center vendors, will want to understand the neutrality commitment in writing. More broadly, each acquisition increases the share of the customer experience stack that depends on one vendor’s roadmap, pricing and integration priorities. That is not inherently a problem, but it is a consideration for teams evaluating multi-year commitments.
Integration timelines are long. The deal is not expected to close until the February-to-April 2027 window, and product integration will follow. Marketing and CX leaders evaluating voice AI now should plan around Cresta’s current platform rather than its future shape inside Salesforce.
