For the Sierra team
For the people building Sierra.
You built one of the best enterprise agents anywhere. Here is why your customers arriving with an agent of their own makes yours even better, and how we would build it with you.
What's in it for Sierra
A customer with an agent resolves faster.
Every one of these is something a Sierra agent would love to find on the other end of the line: a customer who shows up known, consented and ready.
Consented customer context
The customer's own verified profile, history and intent, shared by consent at the start. No more "can you verify your account?" loops.
A standing customer mandate
The customer's agent can authorize bounded actions, a return, a plan change, a payment, within limits the customer set. Fewer escalations, faster resolution.
Receipts on the customer's side
Every step is logged for the customer, so outcomes are trusted and disputes shrink. Good for the brand's compliance too.
Always on, every channel
The customer's agent is reachable around the clock across chat and voice, so resolution can be asynchronous.
Owned-compute privacy
Personalization runs on compute the customer owns (🤫 Puppy One), so the enterprise gets a better outcome without holding the most sensitive data.
Verified identity at the door
Strong, consented identity reduces fraud and account-takeover risk from the first second of the conversation.
Where we design together
Four concrete surfaces.
Agent-to-agent interop
A clean protocol handshake over open standards like MCP and agent-to-agent, so a customer's 🤫 Agent One and a Sierra agent can transact directly, with identity and consent on both sides.
Two-sided evaluation
τ-bench measures agent-user interaction. Together we could extend it to agent-to-agent: how well two capable agents reach a fair, correct outcome.
Voice, both ends
Both sides are moving to real-time voice. A consumer agent that can call, wait and resolve for the customer pairs directly with Sierra's voice channel.
A consent and receipts standard
Co-define what a consented, receipted exchange between a customer's agent and an enterprise's agent looks like: auditable for the brand, private for the person.
Your customer, too
Building with you, and on you.
We would be your customer too. 🤫 is an AI-first business, and we would run our own customer experience on Sierra, starting with Fund A investor relations, then support for 🤫 Agent One, Puppy One and Tag One. We would build with Sierra and on Sierra at the same time, and feel exactly what your customers feel.
Manish Sainani, 🤫's founder and CEO, spent years at Google Core and Google Cloud on AI infrastructure and developer tooling, the kind of large-scale platform work that standards-based agent interoperation needs. He is building 🤫 to put that same caliber of platform in the hands of one person.
The people
The people whose judgment we would love to earn.
Sierra's founders and investor-directors, from their own pages and reputable press. We would rather earn a warm introduction than send a cold email.

A working prototype, not a deck
