Agentforce is Salesforce's platform for autonomous AI agents, with customer service as its flagship act. Because it is grounded in your CRM through Data Cloud, an Agentforce service agent can resolve cases using live customer records, knowledge articles, and Flow automations, all inside the guardrails your admins define, then escalate to a human in Service Cloud when needed. Its Atlas reasoning engine works out intent, gathers the right data, and executes actions, and a low-code Agent Builder lets teams assemble agents from topics and actions without deep engineering. In late 2025 Salesforce added Agentforce Voice, giving those agents a natural phone presence.
Salesforce is not shy about eating its own cooking. The company runs Agentforce on itself as what it calls customer zero, and CEO Marc Benioff has said AI now handles roughly half of Salesforce's own support, letting it shrink support headcount substantially. At the 2024 Dreamforce launch, attendees reportedly built around ten thousand agents in just three days, which tells you something about how quickly the low-code builder puts people to work.
The results customers report are eye-catching: 1-800Accountant says it resolves the majority of its chat conversations autonomously, OpenTable reports similar deflection, and Reddit cut its resolution time dramatically after switching on service agents. Pricing is flexible, spanning a per-conversation rate and a consumption-based credit model, plus per-user editions for teams that want a predictable add-on.
For the vast population of companies already running sales and service on Salesforce, Agentforce is the natural next step, because the agent lives right next to the data and processes it needs and requires no separate integration project to get going. If your business is already built end to end on the Salesforce platform, this is the AI agent that fits your world with the least possible friction and the most context.

Sierra builds conversational AI agents for the enterprise, and it arrived with about as much star power as a startup can carry. It was founded in 2023 by Bret Taylor and Clay Bavor, and if those names ring a bell it is because Taylor co-created Google Maps, served as CTO of Facebook and co-CEO of Salesforce, and currently chairs the board of OpenAI, while Bavor spent eighteen years at Google leading its virtual and augmented reality work. Company lore says the whole thing was hatched over a grilled branzino lunch in Palo Alto.
The product lives up to the pedigree. From a single build, Sierra deploys a branded agent across chat, voice, email, SMS, and even ChatGPT, following your policies, adopting your brand's voice, and escalating gracefully when a conversation gets thorny. Its voice agents are a standout: they hold natural, low-latency conversations, read sentiment, and can even take a credit card or ACH payment over the phone in one uninterrupted call, with no clumsy handoff to a separate system.
Under the hood sits Agent OS, a platform for building, testing, and supervising agents, with tooling to run voice simulations and rehearse behavior before anything reaches a real customer. Pricing is outcome-based, tied to conversations or successful resolutions and wrapped in multi-year enterprise contracts, so Sierra is aimed at large brands rather than weekend experimenters. Reported customers include SoFi, Ramp, and Brex, and the company says its agents already serve a meaningful slice of the Fortune 50.
Sierra's fundraising has kept pace with its towering ambition, vaulting the company into the rarefied tier of the most valuable AI startups in barely two years. For enterprises that want polished, on-brand agents across every channel and are willing to invest the time and budget to do it properly, Sierra is a genuine marquee choice.
