Their agent. Your advocate.
Sierra gives the enterprise a capable agent. π€« gives the customer one too. When both sides are represented, the conversation gets honest β and everyone gets a better outcome.
A proposed alignment from public information β not a claimed joint roadmap.
Sierra's side β the π€« side.
Each row pairs what Sierra gives the enterprise with the owned, consent-first answer π€« gives the customer. Two capable agents, one honest handshake.
| Sierra β the enterprise's side | π€« β the customer's side | Product |
|---|---|---|
| Enterprises deploy branded AI agents to handle customer service across every channel. | The customer arrives with their own private agent β their advocate, not the brand's β so the conversation is agent-to-agent, on equal footing. | π€« Private Agent One |
| Agents are optimized, via outcome-based pricing, to resolve, retain, and save the cancellation. | The customer's agent negotiates for the customer's actual interest β with consent and a receipt for every step β so retention flows stay honest. | π€« Private Agent One |
| Multichannel by design β chat, voice, SMS, email, and inside ChatGPT. | An always-on, voice-first agent that can meet an enterprise agent on any of those channels on the customer's behalf. | π€« Agent One |
| The Agent Data Platform personalizes using the enterprise's data about the customer. | Personalization from data the customer owns, shared by consent β better outcomes without surveilling the person. | π€« Private Agent One + Puppy One |
| Ο-bench brings rigor to reliable tool-agent-user interaction. | Reliability and reproducibility on owned edge compute β two rigorous agents make a cleaner, more trustworthy handshake. | π€« Puppy One |

Win-win-win.

An advocate that handles support, billing, and cancellations for them β less friction, a fair outcome, and a receipt for every step.
Sierra & the brand win

The market wins
