+# Y Combinator Application Video — Talking Points
+
+> **Rules from YC:** 1 minute. Founders talking. No script — use bullet points only. Talk like you're explaining to a friend.
+
+---
+
+## Your Bullet Points (≈60 seconds)
+
+**[0:00–0:10] Who you are**
+- "Hey, I'm Garfield Heron, solo founder of SquareMCP."
+- "I'm a builder who's been in the trenches of API integrations for years."
+
+**[0:10–0:25] The problem**
+- "Every company now needs to post to TikTok, Instagram, LinkedIn, Twitter, WhatsApp, Telegram, Discord, Facebook, and email."
+- "Right now that's 9 different APIs, 9 different auth flows, 9 different docs, 9 different failure modes."
+- "Engineers spend weeks wiring this up. Then it breaks when TikTok changes their API or Meta deprecates a permission."
+
+**[0:25–0:40] What SquareMCP is**
+- "SquareMCP is one API that connects to all of them."
+- "You authenticate once per platform through our dashboard, then call one endpoint: `publish_post` or `send_message`."
+- "We handle the tokens, the rate limits, the retries, the API changes."
+- "It's built on the Model Context Protocol — an open standard — so AI agents can use it too."
+
+**[0:40–0:52] Traction / proof**
+- "We've got the full TikTok sandbox working, Facebook Graph API, and SMTP/email."
+- "We're live at squaremcp.com with per-user credential storage, usage tracking, and invoice-based billing."
+- "TikTok app review is in progress."
+
+**[0:52–1:00] Why you, why now**
+- "I lived this pain. I'm the exact person to fix it."
+- "AI agents need to post to social too — and they need a standard way to do it. MCP is that standard."
+- "We're building the infrastructure layer that every AI-native company will need."

+
+## Recording Tips
+
+1. **Use your phone or laptop webcam** — 1080p is plenty. Good lighting matters more than camera quality.
+2. **Look at the lens, not the screen.** It feels like eye contact.
+3. **Don't memorize.** Glance at these bullet points, then talk naturally. Stumbling is fine — YC prefers real over polished.
+4. **One continuous take.** No cuts, no B-roll, no music. Just you talking.
+5. **Background:** clean wall, or a desk with a monitor showing your product. Nothing distracting.
+
+## After Recording
+
+1. Export your raw video as `my-recording.mp4` (1920×1080 ideally)
+2. Replace the placeholder in `YCAppVideo.tsx` with an `<OffthreadVideo>` component pointing to your file
+3. Re-render: `npx remotion render YCAppVideo out/final-yc-video.mp4`
