Salesforce stock deepens voice AI push with Cresta deal

Salesforce agreed on November 2, 2026, to acquire Cresta, a voice-first customer experience platform, in a move that deepens its push into artificial intelligence for customer service. Salesforce announced the transaction in a company release.

Salesforce stock traded at 192.22 euros on Lang & Schwarz at 15:10 CET on Monday, November 9, 2026. A matching Xetra closing comparison is not included in this report.

Voice AI fills a service gap

Cresta's software is designed to handle complex customer calls from start to finish. It can guide human representatives during live conversations, analyze interactions and help companies improve automated voice systems. Salesforce said the platform is used by brands including Marriott, Comcast and Alaska Airlines.

The planned combination with Service Cloud is intended to connect customer conversations with customer records and business outcomes such as resolution, retention and revenue. Cresta will continue supporting the contact center and telephony platforms used by its customers after the transaction closes, according to Salesforce.

For Salesforce, the acquisition adds a voice layer to an AI strategy centered on Agentforce and Service Cloud. The move also follows a series of purchases and planned transactions aimed at expanding the company's enterprise AI and customer engagement offerings.

Integration remains the key test

TechTarget reported on November 4 that Salesforce has been expanding its contact center capabilities and that Cresta could help close a gap in voice AI. Rebecca Wettemann, CEO and principal analyst at Valoir, said the acquisition could give Salesforce greater credibility in contact center products and help bring voice-conversation context into customer data.

The same analysis highlights a potential challenge for companies that partner with Cresta. Salesforce says the platform will continue to support other contact center and telephony systems, but ownership of the technology could prompt partners to reconsider their relationships as Salesforce expands its competitive position.

Salesforce has not disclosed the purchase price. TechTarget said The Information reported a transaction value of 2.7 billion US dollars. The deal remains subject to customary closing conditions and regulatory approvals and is expected to close in the first quarter of fiscal 2028, between February and April 2027.

The broader S&P 500 market provides the main benchmark context for US-listed technology shares.
