Comparing Moveworks and Sierra AI? Both are AI Agents & Chatbots and Enterprise tools in the directory, which is why buyers put them on the same shortlist. Below is a side-by-side look at how they price, what they integrate with, and when each is the better fit, so you can pick on the facts rather than either vendor's own sales page.

Moveworks is an AI assistant platform for an entire workforce, built to search and act across the business applications employees already use. An agentic reasoning engine decides what a request actually needs, a marketplace ships more than 1,000 prebuilt agents, and enterprise search reaches across 50 or more systems including OneDrive, SharePoint, Confluence and Outlook. Agent Studio is the low-code builder for teams that want their own agents, and the assistant answers in more than 100 languages across chat, web, mobile and portals.
The Slack behaviour is the part worth understanding, because it is more aggressive than most. Any employee can DM the assistant directly, but Moveworks also puts a bot in the public IT channel, a feature it calls Channel Resolver. It reads every message posted there, and when it predicts it can remediate the issue it steps in: it DMs the employee to resolve the problem, then updates the channel so the answer is visible to everyone. Moveworks describes the resolvable set as software provisioning, account unlocks, installation instructions and the guest WiFi password, which is to say the bulk of what an ask-IT channel actually receives. The same assistant runs in Microsoft Teams, and since a January 2025 expansion of the Microsoft alliance it is also reachable as an agent inside Microsoft 365 Copilot.
Bhavin Shah, Vaibhav Nivargi, Varun Singh and Jiang Chen founded the company in 2016, and it raised more than $300 million from investors including Tiger Global and Kleiner Perkins. On March 10, 2025 ServiceNow agreed to buy it for $2.85 billion in cash and stock, the largest acquisition in ServiceNow's history, and the deal has since closed. Moveworks says more than 350 large enterprises and over 5 million employees use it, including 10 percent of the Fortune 500. Named customers include CVS Health, Toyota North America, BambooHR, Instacart, Coca-Cola Consolidated, AkzoNobel, Procore and Micron.
Pricing is not published anywhere on the site: this is an enterprise sale with a quote at the end of it. Choose Moveworks if you are a large enterprise with a busy ask-IT channel and you want an assistant that resolves in the channel rather than deflecting to a portal, and doubly so if you are already a ServiceNow shop. Skip it if you are under a few thousand employees, where the deployment effort and the contract size will both outrun the problem you are solving.

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.
