For the people building Sierra.
If you're on the Sierra team, this page is for you. You built the best enterprise agent in the market. Here is why your customers arriving with their own agent makes yours better β and how we'd build it together.
Written for Sierra, from public information β an honest invitation, never a claimed deal or endorsement.
A customer with an agent resolves faster.
Every capability below is something a Sierra agent in the wild would love to meet on the other end of the line: a customer who shows up known, consented, and ready to transact.
Consented customer context
The customer's own verified profile, history, and intent β shared by consent at the start of a conversation. No more 'can you verify your account?' loops; the enterprise agent gets accurate, permissioned context and resolves faster.
A standing customer mandate
The customer's agent can authorize bounded actions (a return, a plan change, a payment) within limits the customer set β fewer escalations to a human, faster resolution.
Receipts & audit on the customer's side
Every step is logged for the customer, so outcomes are trusted and disputes shrink β good for the brand's compliance too.
Always-on, cross-channel reachability
The customer's agent is reachable 24/7 across chat and voice, so resolution can be asynchronous β no hold music, no dropped threads.
Owned-compute privacy
Personalization runs on compute the customer owns (π€« Puppy One), so the enterprise gets a better outcome without having to hold the customer's most sensitive data.
Verified identity at the door
Strong, consented identity (π€« Gold ID and biometrics) reduces fraud and account-takeover risk for the enterprise from the first second of the conversation.
Concrete surfaces, not vibes.
Agent-to-agent interop
A clean protocol handshake (over open standards like MCP / agent-to-agent) so a customer's π€« Agent One and a Sierra enterprise agent can transact directly, with identity and consent on both sides.
Two-sided evaluation
Sierra's Ο-bench measures agent-user interaction; a design partnership could extend it to agent-to-agent β how well two capable agents reach a fair, correct outcome. A natural shared research surface.
Voice, both ends
Both sides are moving to real-time voice. A consumer voice agent that can call, wait, and resolve on the customer's behalf pairs directly with Sierra's voice channel.
A consent & receipts standard
Co-defining what a consented, receipted customerβenterprise agent exchange looks like β auditable for the brand, private for the person.
Building with you, and on you.
We would also be a customer. π€« is an AI-first business β first a Fund A (the founders' fund), then a products, solutions, and services company. We'd use Sierra to run our own customer experience β starting with Fund A investor and LP relations, then support for π€« Agent One, Puppy One, and Tag One β so we build with Sierra and on Sierra at the same time, and feel exactly what our customers feel.
Manish Sainani, π€«'s founder & CEO, spent years at Google Core and Google Cloud working on AI infrastructure and developer and AI tooling β the kind of large-scale AI-platform and developer-experience work that maps directly to building reliable, standards-based agent interoperation. He is building π€« to put that same caliber of platform in the hands of the individual.
People we both respect.
We'd rather earn a warm introduction than cold-call. These are the publicly-known people around Sierra β founders and investor-directors β whose judgment this idea would have to earn.
Bret Taylor
Chairs the company and OpenAI's board β the relationship starts and ends with his conviction.
Ravi Gupta
Investor-director who led Sequoia's investment; a credible board-level path to a warm introduction.
Peter Fenton
One of Sierra's first investors and a board director; his public bio lists the Sierra directorship.
Sierra is private and does not publish a full board roster. The names above are the board members verifiable from reputable press and the individuals' own pages. Lead investors also include Greenoaks (Neil Mehta), Tiger Global, and GV (Alphabet's venture arm, which co-led the May 2026 round) β publicly tied to Sierra as investors, but not confirmed as directors.
One conversation.
No deal, no pressure β just a conversation with Manish Sainani about an honest agent-to-agent handshake that serves the customer and the brand at once. We'll bring a working prototype, not a pitch deck.

This is a public study and an open, honest invitation from π€« hushh β an admiration of Sierra's public work and a proposal to explore interoperation on behalf of customers. It is not a claimed deal, affiliation, endorsement, or sponsorship. Facts are drawn from Sierra's own site or reputable press (press-reported figures labeled "reported"); individuals are named only with a cited public presence. Companies and roles change β verify against the primary sources before acting.
