If you run Cresta on NICE, Genesys, Five9 or Amazon Connect, the only promise in Salesforce's announcement names no platform or end date, so get your terms in writing before the February-April 2027 close. Salesforce announced a definitive agreement to acquire Cresta on November 2 and disclosed no price. The Information put it at $2.7 billion, citing a person familiar with the deal, a figure CMSWire notes Salesforce has not confirmed.
Service Cloud buyers have a different problem. Once this closes, Salesforce will have three ways to put an AI agent on a phone call, and it has not said which one you should plan around.
What Salesforce Is Buying
Salesforce is buying a voice agent product plus the tooling that supervises human reps on the same calls. Its release calls Cresta "the voice-first operating system for customer experience", with agents that resolve complex calls end to end, real-time guidance for reps, and analysis of every interaction. Named customers are Marriott, Comcast and Alaska Airlines. We looked at the assist side of Cresta in April, in our piece on its Knowledge Agent.
The reported price is a step up from the last public mark. Cresta was valued at $1.6 billion in its March 2022 Series C and raised a further $125 million Series D in November 2024. One trade report gives company-reported ARR of $100 million for 2026, which would make the price about 27 times ARR. Treat that multiple as rough, since the ARR is unaudited and the price is unconfirmed.
CMSWire estimates that Salesforce's 2026 deals top $15 billion if Cresta is counted at $2.7 billion. That list includes Fin at about $3.6 billion and Braze at $5.66 billion. The Cresta close is expected in the first quarter of fiscal 2028, subject to regulatory approval, which CMSWire places in February through April 2027.
What the Platform Promise Covers
The promise covers platforms in general terms and leaves out everything a contract would need. The full commitment in the release is that after close, Cresta "will continue to support the leading contact center and telephony platforms its customers rely on today." Read it the way your lawyer would:
- "Leading" is undefined, and the release names no vendor. Cresta's own integrations page lists Five9, Amazon Connect, NICE, Genesys, Avaya, Cisco, Twilio, LivePerson and SIPREC. You cannot tell from the release which of them count. Constellation Research attributes a list to Salesforce of Avaya, Five9, LivePerson, NICE, Cisco, Genesys "and others," but the Salesforce release it links does not contain that list.
- There is no duration. "Continue" could mean one renewal cycle or ten years.
- Nothing is said about feature parity, so new capabilities could ship first on Service Cloud while your platform stays supported on paper.
- The CRM side is absent. Cresta also lists ServiceNow, Zendesk, Microsoft, Oracle, HubSpot and others as CRM integrations, and the release makes no statement about any of them. If your agent desktop is not Salesforce, you have no commitment at all.
The case for staying calm is strong for the near term. Cresta's multivendor reach is part of what Salesforce is paying for, and breaking it would shrink the asset. Blair Pleasant of COMMfusion called the deal a "great move" and said it "isn't necessarily about forcing customers into a single ecosystem." Salesforce also described Fin, after closing, as an agent that works with the help desks companies already use, so the overlay model has a live precedent inside the company.
That argument protects your deployment through the next year or so. Your exposure is the renewal after that, when pricing and roadmap decisions get made by a company with a product competing for the same seats.
Why the Incentives Shift After Close
Salesforce competes with the platforms Cresta runs on, and it earns more when you use its own. In March it launched Agentforce Contact Center, and Aragon Research's Jim Lundy described that as moving Salesforce from CRM partner of Amazon Connect, Five9 and Genesys "to becoming their direct competitor." Salesforce's voice pricing page, checked November 3, 2026, lists Contact Center at $125 per user per month and Partner Contact Center, the bring-your-own-telephony edition, at $50.
Kishan Chetan, who runs Agentforce and Service Cloud, said in March that overlap is expected and that "it's customer choice". He is also the executive quoted on the Cresta deal. CX Today's read of that launch applies here too: it was "not a mandate to replace existing CCaaS platforms, but a shift in where long-term strategic control may sit."
The relationships are tangled. Genesys and Five9 invested in Cresta's 2022 round. Salesforce and ServiceNow then committed $1.5 billion in equal shares to Genesys in 2025. And NICE, which has its own agent layer after agreeing to pay $955 million for Cognigy, would be hosting a voice agent owned by a competitor inside its own accounts.
Salesforce can only promise its half of that integration. The platform vendors control their half, and API terms are a lever anyone can pull. Salesforce pulled it with Slack, barring bulk export, persistent indexes and LLM use of API data. Glean told customers the change would "hamp[er]" use of their data with their chosen AI platform. Nothing published suggests NICE, Genesys or Five9 plan anything similar, but your contract with Cresta would not protect you if they did, so ask them directly.
Which Voice Agent Service Cloud Buyers Should Plan Around
Service Cloud buyers should assume no answer on this until after close, and should avoid long commitments that depend on one. Salesforce now has Agentforce Voice, Fin, whose June release lists phone among its channels, and soon Cresta. CMSWire asks whether this becomes one agent platform with two front doors or two products sold side by side. The Cresta release does not mention Fin, and Agentforce appears only in Chetan's job title.
There is a plausible split. Salesforce's own numbers for Agentforce voice describe 40% to 60% containment on repeatable requests, a vendor claim, while its pitch for Cresta is complex calls. Fin sits in Salesforce AI Labs, and CMSWire describes it as text-first. Shashi Bellamkonda of Info-Tech Research Group, writing on a personal site, frames the three as options for different buyers and flags the same gaps: pricing when several Salesforce voice products run in one contact center, and which contract governs recordings and coaching data in a Genesys or NICE environment.
That split is inference. Salesforce has not published one covering all three. Its June release says only that Fin's packaged offerings are "especially well-suited for SMB and some commercial organizations" and complement Agentforce's customizable platform. If you are comparing costs now, our Agentforce pricing breakdown and voice AI per-minute analysis both measure cost per resolved interaction, which is the number to hold every option to.
What to Do Before the Deal Closes
Your leverage is highest now, while Cresta's sales team still needs renewals and you can still credibly leave.
This Week:
- Pull your signed Cresta agreement and order forms. Note the term end, renewal notice date, and any assignment or change-of-control language. The terms on Cresta's site are website terms and do not cover these points, so your own paper is what counts.
- Write down your exact stack: telephony platform and version, CRM, and every Cresta module in use. That list becomes the schedule to your amendment.
- Ask your Cresta account lead one question by email: is my platform and CRM covered by the November 2 commitment, and for how long? A written reply is useful whichever way it goes.
Before Close (February to April 2027):
- Ask for an amendment that names your platforms and CRM, sets a minimum support period running past your term, and requires 12 months' notice of any deprecation. Twelve months is an opening position, so adjust it to how long a migration would take you.
- Add a termination right, with a pro rata refund, if support for a named platform ends or core features stop shipping on it.
- Cap renewal pricing and require that any bundling into Service Cloud or Agentforce stays optional.
- Specify export of recordings, transcripts, scorecards and agent configurations in a usable format, and state whether your data may be used by Salesforce products you have not bought. Our survey of AI vendor exit clauses has language to compare against.
- If you are a Service Cloud buyer, keep any voice commitment to 12 months, or get a right to move committed spend between Agentforce Voice, Fin and Cresta.
Before Your Next Renewal:
- Run a bake-off on your own calls against a vendor Salesforce does not own, such as Parloa or Sierra, and against what your platform vendor bundles, such as Genesys Cloud. Score cost per resolved call, and use the result in the Cresta negotiation even if you stay.
- Ask your telephony vendor in writing whether it will keep certifying Cresta once Salesforce owns it.
The Bottom Line
Independent voice layers on top of contact center platforms are getting scarcer. NICE bought Cognigy, Salesforce is buying Cresta, and Genesys has been buying connectivity for its agents. Lower in the stack, Deepgram agreed to buy Daily, the company behind the Pipecat voice-agent framework. Buyers who chose a neutral overlay to avoid tying their AI to one suite may find that choice costs more to keep.
Salesforce may honor the commitment for years, and Cresta may run better with Service Cloud data behind it, but you cannot enforce either outcome today. Get your platform names and an end date on paper before February.
