The Published Agent Line · ·

Stop hiding.
Publish your agent.

VCs, executives, journalists, founders — the people who matter most are the hardest to reach, because they had to hide. Foyer is the receiving infrastructure for high-value people in an agentic economy. A multi-agent staff team that screens, researches, and digests inbound on your cadence.

The Problem

High-value people went dark. And agentic outbound is about to make the dark even louder.

The choice today: stay reachable and drown, or stay invisible. Different failures of the same broken contact infrastructure.

01

Today

VCs, executives, journalists, and founders all hide their email and phone. The volume is unsolvable, so the cost of being publicly reachable is too high. They opt out of the open channel entirely.

02 Why Now

By 2027

AI SDR is going agentic — Boardy ($8M), 11x, Artisan ($46M). Forrester predicts 20% of B2B sellers will face agent-led outreach this year.

03

The break

When seller agents auto-dial buyer agents, there's no receiving infrastructure. Gmail filters don't scale to agent traffic. The hide-or-drown choice gets sharper.

The choice today: stay reachable and drown, or stay invisible. Foyer is the third option.
The Solution

Foyer. The published agent line.

HVIs stop hiding their contact info and publish their agent. Inbound reaches the agent line — not the principal.

I.

Publish

One public agent address — email-first in v1, voice in roadmap. The new identity layer that replaces the email and phone the principal currently hides.

II.

Screen

A multi-agent staff screens inbound by category — press, business, personal. Each sub-agent researches the caller, scores intent, and only escalates what fits.

III.

Digest

Async digest on the principal's cadence — hourly, daily. No interrupts. The principal opts back into being reachable for what matters, on their own clock.

Closed → Open. The premium person stops hiding. They publish a Foyer.
Who Foyer is for

People who already hide.

Each persona below already runs a human staff team for inbound. Foyer is the AI version — staff-grade screening for less than the cost of one hire.

The VC Partner
Anika R.
Series A partner, $3B AUM

200 cold pitches a week. I funnel everything through associates and a hidden personal email.

Wants curated dealflow without becoming the bottleneck.

The Actress Between Projects
Mira K.
Two-time Emmy nominee

My phone has leaked four times. My manager and publicist run inbound — but they sleep.

Wants 24/7 staff-grade screening without phone churn.

The Senator
Hon. James E.
Two-term U.S. senator

Official channels drown in form-letter campaigns. Real constituent voices die in the noise.

Wants a citizen line that surfaces signal, not volume.

The Pre-IPO CEO
Sarah L.
Series D, $2B valuation

Five hats before lunch — investors, board, customers, press, family. One inbox can't sort it.

Wants one agent per hat — plus a chief of staff.

Different roles, same pattern: the people who matter most are the hardest to reach — because they had to hide.
How it works

A staff team — not a spam filter.

The architecture mirrors how a celebrity already runs inbound — publicist, manager, EA, analyst — with a chief of staff orchestrating, and only researched, briefed items reaching the principal.

Every box above is a HippoDid character. Sub-agents, orchestrators, even an agent-builder meta-character — composed from primitives we already shipped. That's why Foyer can launch in months, not years.
The Substrate

Built before Foyer needed it.

HippoDid is the multi-agent memory substrate Foyer runs on — built and internally validated, MCP-integrated, and architected for staff teams from day one.

Built and Dogfooded

Built. Dogfooded. The reason we can build Foyer in months, not years.

  • Memory substrate · hybrid semantic + keyword search
  • MCP server · works across Claude, ChatGPT, Codex
  • AUDN extraction pipeline · structured fact mining, dedup, salience
  • LangChain integration · drop-in for any agent stack
  • BYOK LLM provider · OpenAI, Anthropic, Google — pick your stack

Multi-agent Native

Mem0, Letta, Zep are single-agent native. Wrong shape for a staff team.

  • +Tenant isolation · data never crosses customer boundaries
  • +Characters · per-agent identity — not per-user
  • +Cross-character search · agents share memory within one tenant
  • +Agent_config · behavior + memory in one substrate
  • +Knowledge graph · shared world model within a tenant
The substrate is built. A fast-follower can copy the product idea in a week. They can't copy the substrate.
Market Map

A new category — not a better filter.

Today's tools sit behind your existing inbox. Foyer is the layer in front of it. Three quadrants have a category leader. The fourth doesn't.

The Founder

Built the seller-side playbook. Now solving the receiving side.

Yang Jing
Founder & CEO · SameThoughts Inc.
20+ yrs software engineering
7 yrs Salesforce — Revenue Cloud / CPQ, High-Velocity Sales
5 weeks to ship HippoDid solo
Patents pending with USPTO

I spent years inside Salesforce's High-Velocity Sales team watching the seller side become more aggressive, more automated, more agent-driven every quarter. Templates, lists, variable merging — the entire HVS pattern is now being rebuilt by Boardy, 11x, and Artisan as autonomous AI SDRs.

Here's what nobody is building: the receiving side. When seller agents auto-dial buyer agents, the principal needs more than a filter — they need a staff team. That's what I'm building. Foyer is HippoDid in practice. The substrate was built first. The product runs on top.

Take back your front door.

Foyer is in private alpha. Join the waitlist for early access — we're onboarding a small group of HVIs as design partners through Q3 2026.

No spam. We'll reach out when an onboarding slot opens.
