What Are You Building

What is your company going to make?

SquareMCP is an AI communications manager for non-technical professionals —
mortgage brokers, publishers, coaches, and real estate agents who spend 3-5
hours a week manually copying and pasting content across LinkedIn, Instagram,
Facebook, WhatsApp, and email.

Instead of logging into each platform individually, users tell Claude what they
do, connect their accounts once, and Claude drafts platform-optimized content
for their approval. One input becomes a LinkedIn post, a Facebook update, an
Instagram caption, and a follow-up email — tailored for each channel. Users
approve with one click or let the system post automatically once they trust it.

Under the hood, SquareMCP is an MCP (Model Context Protocol) gateway — the
emerging open standard for giving AI agents authenticated access to external
services. We handle OAuth tokens, credential storage (AES-256-GCM encrypted
per-customer in Redis), rate limits, retries, and API changes across 10+
platforms so neither the end user nor the developer has to.

The platform is live at app.squaremcp.com with multi-tenant auth, usage
tracking, invoice-based billing, and working integrations for LinkedIn,
Facebook, Instagram, Twitter/X, TikTok, WhatsApp, Telegram, Discord, Snapchat,
and email. TikTok app review is in progress. First users are onboarding this week.

Location

Where do you live now, and where would the company be based after YC?

Miami, FL, United States / San Francisco, CA, United States

Explain your decision regarding location.

I'm currently based in Miami. During YC I would relocate to the Bay Area for the
batch — the density of AI founders and the YC network is worth being present for.
Post-YC, the company would stay in San Francisco or be remote-first depending on
early hire strategy.

⚠️ Adjust if your preference is different.

Progress

How far along are you?

The backend is fully built and deployed. SquareMCP runs on a MicroK8s cluster
at hermes.squaremcp.com with:

- 10+ platform integrations: LinkedIn, Facebook, Instagram, Twitter/X, TikTok,
  WhatsApp, Telegram, Discord, Snapchat, Email (IMAP/SMTP, 7 accounts), Obsidian
- Multi-tenant credential isolation: per-customer AES-256-GCM encrypted credentials
  in Redis, customer resolution from API key or JWT cookie
- Full SaaS auth and billing: signup/login (bcrypt + JWT), 4-method auth, usage
  tracking on every tool call, plan tiers (Free/Starter/Growth/Enterprise),
  invoice generation at $0.05/action
- Admin panel: customer management, usage view, invoice generation and sending
- Web app at app.squaremcp.com: dark-theme SPA with platform connection cards,
  OAuth flows, usage bar, invoice list
- Marketing site at squaremcp.com with pilot request form
- TikTok app review submitted

Two named pilot users — a mortgage broker and a book/magazine publisher — are
ready to sign up this week. Neither is technical. The chat-first content manager
UI (the end-user product layer) is the current build sprint.

How long have each of you been working on this? How much of that has been full-time?

I started building Hermes MCP in March 2026 as a personal tool — originally a
Yahoo Mail server for Claude. Within 6 weeks it had grown to cover 10+ platforms,
multi-tenancy, and a full SaaS billing system.

I've been building full-time since April 2026. I have 15+ years of experience
in enterprise API platforms, integrations, and distributed systems — this is
not a new problem for me, just a new distribution channel (AI agents instead
of human developers).

⚠️ Adjust dates/timeline if needed based on your actual start.

What tech stack are you using, or planning to use?

Backend: TypeScript / Node.js (MCP server + REST API)
Database: MySQL 8 (user/billing data), Redis 7 (per-customer encrypted credentials,
          session state, audit logs)
Infrastructure: MicroK8s single-node cluster, Traefik ingress, Let's Encrypt TLS,
                local container registry
Auth: bcrypt + JWT session cookies, 4-method auth (global API key → customer API
      key → OAuth Bearer → JWT cookie)
Platform SDKs: Meta Graph API (Facebook, Instagram), LinkedIn API v2, Twitter/X
               API v2, TikTok Video Publish API, WhatsApp Cloud API, Telegram Bot
               API, Discord API v10, Snapchat Marketing API, IMAP/SMTP

AI models: Claude Sonnet 4.6 (claude-sonnet-4-6) via Anthropic API — used for
           content generation, platform-aware adaptation, and the chat interface
AI coding tools: Claude Code (all backend, SaaS system, integrations, and
                 infrastructure built with Claude Code)

Frontend: Vanilla JS / HTML / CSS (squaremcp.com marketing site + app.squaremcp.com
          SPA) — no framework, intentionally minimal
Testing: Playwright (E2E, desktop + mobile, screenshot diffing on squaremcp.com)

Traction

Are people using your product?

No — first users onboarding this week.

Select "No" on the form. Mention the two pilot users in the progress section.

Do you have revenue?

No — invoice-based billing is built and ready; first invoices generate when
first users hit usage thresholds.

Select "No."

Idea

Why did you pick this idea? Do you have domain expertise? How do you know people need this?

I've spent 15+ years building and integrating enterprise APIs — payments,
identity, messaging, data pipelines. I've lived the pain of stitching together
multiple platform APIs firsthand: different auth models, inconsistent rate limits,
breaking changes with no notice.

When I started using Claude daily for my own work, I wanted it to be able to
act on my behalf — post to LinkedIn, send a WhatsApp, respond to email. There
was no clean way to do that without writing brittle per-platform integrations.
I built SquareMCP to solve my own problem first.

Then I called a mortgage broker friend who doesn't write code. Before I could
finish explaining it, he said: "I send out lots of emails and social media, it
burns my time, and I get little response. I want a way to push out information
and videos and monitor my email and respond with appropriate answers and questions."

He didn't describe a scheduling tool. He described a full communications manager —
outbound posting AND inbound email monitoring with AI-drafted responses. He
described the exact product I built, unprompted, in one sentence.

Same reaction from a magazine publisher — different content, same pain.

I know people need this because the first user I called told me exactly what to
build before I said a word about what the product did.

Who are your competitors? What do you understand about your business that they don't?

Two competitive landscapes:

1. Social media scheduling tools (Buffer, Hootsuite, Ocoya, SocialPilot):
These are form-based scheduling tools with AI content features bolted on. They
require users to think like marketers — content calendars, posting schedules,
analytics dashboards. Non-technical professionals find them complex and abandon
them. They don't have AI agency: they can schedule a post you write, but they
can't have a conversation with you and generate the post from your context.

2. MCP gateway / developer platforms (Composio, Kong, MintMCP):
These target developers building AI applications and require significant
engineering to integrate. They have no end-user product. A mortgage broker
cannot use Composio.

What we understand that they don't: the user interface for AI-era social media
management is a chat window, not a scheduling dashboard. The product is "tell
Claude what you do and it handles the rest" — not "here are your 47 settings."
The MCP infrastructure we built is the engine; the chat-first UX is the product.
Non-technical professionals are the fastest path to revenue, and they're
completely unserved by both competitive categories.

How do or will you make money? How much could you make?

SaaS subscription + usage metering:

- Free: 100 actions/month, 1 workspace, 2 connectors (lead gen)
- Starter: $199–499/month — 10 connectors, RBAC, audit logs
- Growth: $1,500–3,000/month — SSO, private networking, SLA
- Enterprise: $20,000–100,000+/year — VPC/on-prem, compliance, custom connectors

Usage metering at $0.05/action above plan limits (already implemented).
Setup fees for enterprise onboarding: $3,000–$15,000.

TAM: 30M+ small business owners in the US who use social media for marketing.
If 1% of US mortgage brokers (330,000 total) pay $199/month that's $65M ARR
from one vertical alone. The platform model means every new vertical (real
estate, publishers, coaches, insurance agents) multiplies that.

Other ideas you considered applying with:

1. AI trading bot management platform — I've built and run multiple algorithmic
   forex trading systems (MQL/MetaTrader). A platform to manage, monitor, and
   deploy AI-generated trading strategies is a real gap.

2. Hermes MCP as pure developer infrastructure — sell the MCP gateway layer to
   developers building AI apps, without the end-user product on top. This is
   still a valid B2B opportunity as AI agents proliferate.

Curious

What convinced you to apply to YC?

I've been using Claude Code with the gstack office-hours skill to pressure-test
my thinking on SquareMCP. The diagnostic forced me to get specific: named users,
articulated demand, challenged assumptions. At the end of the session the tool
said "GStack thinks you are among the top people who could do this" and asked
if I'd consider applying to YC. I said yes. So here I am.

The honest answer is that I've been building for a long time but always as an
employee or contractor, never as a founder with a company I own. This is the
first time the infrastructure, the product idea, and the timing all feel right
simultaneously.

How did you hear about Y Combinator?

I've followed YC and Garry Tan's work for years. The Lightcone podcast
"Vertical AI Agents Could Be 10X Bigger Than SaaS" was the specific episode
that made me think SquareMCP fit the thesis.

Video

Your talking points are in YC_APPLICATION_TALKING_POINTS.md.

⚠️ Update the video script — the current script pitches the developer-facing MCP gateway angle. Consider updating it to lead with the end-user story: "I showed this to a mortgage broker. He said: when can I use this?" That's more compelling than "9 different APIs, 9 different auth flows."

The product demo link is https://squaremcp.com/ — make sure the hero copy reflects the end-user value ("AI that posts for you") before the reviewer visits.
