Salesforce buys Cresta to bring voice AI into customer calls
Salesforce signed a definitive agreement on November 2, 2026 to acquire Cresta, a voice AI company for customer service. Salesforce did not disclose a price; The Information reports it at about $2.7 billion.
Key facts
- Salesforce signed a definitive agreement to acquire Cresta on November 2, 2026.
- Salesforce did not disclose the price; The Information reports about $2.7 billion.
- Closing is expected in the first quarter of fiscal 2028 and still requires regulatory approval.
What Cresta does
Cresta calls itself a voice-first operating system for customer experience. Its software does three things:
- Voice agents: they handle even complex customer calls from start to finish without a human stepping in.
- Live coaching: human service reps get guidance during the call.
- Conversation analysis: every interaction is analyzed, and the results are used to test and improve the voice agents.
Salesforce names Marriott, Comcast and Alaska Airlines among Cresta's customers.
What Salesforce plans
Cresta's conversation analysis is set to connect with Salesforce customer data and Service Cloud. The idea is that companies can link each call to the customer's history and to outcomes such as resolution, retention and revenue. Salesforce says Cresta will keep supporting the contact center and telephony platforms customers already use after the deal closes. The announcement does not say which ones or for how long.
When the deal takes effect
The acquisition is expected to close in the first quarter of Salesforce's fiscal year 2028, which starts in February 2027. It still needs regulatory approval, among other conditions, and the two companies remain separate until then. Salesforce has not published the price; the $2.7 billion figure comes from The Information, citing a person familiar with the deal.
The move fits a pattern: large software vendors are buying voice AI because the phone is still the most expensive channel in customer service.
What this means for you
- Voice AI on the phone is becoming a standard part of big service platforms rather than a niche add-on.
- Salesforce Service Cloud customers will likely get voice agents and call analysis from a single vendor over time.
- Until the deal closes in 2027, nothing changes for existing customers of either company.
How to use this
Write down the three most common reasons customers call you and the best answer to each. With that list, you can test any voice AI fairly before choosing a vendor.
Luigi's take
In customer service, the phone is where a lot of trust is won or lost. An AI that takes over calls entirely is not just a technology question. It shapes how your brand sounds when a customer has a problem. Salesforce wanting to measure success by resolution, retention and revenue is the right approach. Minutes saved alone tell you very little.
My advice for smaller companies: don't wait for the big platform. Write down your three most common call reasons and what a good answer sounds like. You will need that list for any voice AI, whichever vendor you pick. And at the start, always keep an easy route to a human.
