Sierra hits $100M ARR milestone in 7 quarters | Sierra

Sierra just hit $100M in ARR — seven quarters after we launched in February 2024. That’s a heck of a lot quicker than we expected, and makes Sierra one of the fastest-growing enterprise software companies in history.

Credit goes to our amazing team, who’ve worked their tails off to build the business, and to our growing band of customers — the real pioneers of applied AI.

There’s an agent for that, and it runs on Sierra

It was a fair bet that Internet-era companies would be quick to experiment with AI agents, and we’re thrilled to work with Deliveroo, Discord, Ramp, Rivian, SoFi, Sonos, Tubi, Wayfair, and more. But two years ago, neither of us imagined that storied businesses like Next (founded in 1864), ADT ( 1874), Bissell ( 1876), Safelite ( 1947), Vans ( 1966), Cigna (formed in 1982 with the merger of CG, 1865, and INA, 1792!), SiriusXM ( 1990), and DIRECTV ( 1994) would adopt AI quite so fast, and with such great effect.

Agents built on Sierra can now do everything from authenticating a patient, returning a pair of shoes, ordering a new credit card, finding a W-9, or helping fix a broken windshield to originating a mortgage — with homebuyers who use Rocket Mortgage’s Digital Assistant converting 4x faster. In the U.S., our customers serve:

• More than 95% of Black Friday shoppers;
• More than 50% of families in healthcare;
• More than 90% of the media ecosystem; and
• More than 70% of the value chain in fintech — from banking to payments, insurance, and investments.

The Sierra difference

Sierra is the leader in our category, and we’ll extend that lead by focusing on the long term — helping companies build deeper relationships with their customers, versus short-term cost cutting and automation.

• Increase the lifetime value of your customers: Our new Agent Data Platform gives agents the memory and intelligence to move from support to sales, loyalty, and retention. It’s the promise of personalization made real.
• Build a single agent for every channel: Agents built on Sierra work over the phone, with your IVR, chat, WhatsApp, email — in over 34 languages — and you can publish them to AI-native channels like ChatGPT.
• Manage even the most complex processes: Sierra is built for Fortune 1000 companies — with industry-leading security and compliance guardrails that work for heavily regulated businesses in financial services and healthcare. 50% of the companies using Sierra have revenue over $1 billion, and 20% over $10 billion.
• Empower operations teams to move quickly: CX teams can build the most powerful agents (not just standard operating procedures masquerading as agents) without engineering support — enabling them to go live in weeks.
• Pay for a job well done: Sierra’s outcome-based pricing aligns our success with our customers — keeping us accountable for the results we promise.

Answering questions is easy, but building lasting relationships with customers is much, much harder. Sierra exists to help the great companies of the world show up at their best, day in, day out.

Because when people feel understood and appreciated, they spend more, stay longer, and tell their friends. That’s how you build a valuable brand, and an even more valuable business.
