The Anti-Slop
Content Engine.
Send a voice note. Drop in years of PDFs, calls, and docs. Your AI agent team turns it into your Second Brain, then into posts only you could write.
Most Content Is All AI.
LinkedIn is full of AI content that all sounds the same. Great content needs your thinking, not a chatbot’s. HeartStack amplifies your voice. It never replaces it.
Capture It Anywhere. Ship It Everywhere.
Your best ideas hit on a walk, mid-meeting, between investor calls. Send a voice note, a photo, or a URL from anywhere, even WhatsApp. Mika extracts the insight and ranks it in seconds.
“Just got off a call with our biggest enterprise prospect. They said the reason they chose us over the incumbent is our onboarding speed. 3 days vs 3 months. That’s the real moat, not the model.”

Kai’s draftEveryone’s building better models.
Almost nobody’s building better onboarding.
Our biggest enterprise deal closed last week. When I asked why they picked us, the answer wasn’t accuracy, features, or pricing.
It was: “We were live in 3 days. Your competitor quoted 3 months.”
Kai is rewriting this section...Co-Create With AI. Never Outsource Your Thinking.
Pick an entry, choose an angle, and Kai drafts in your voice. Every edit teaches him. Each draft sounds more like you than the last.
Quality Gate, Not Regenerate Button.
70+ slop patterns. Multi-dimensional scoring. Specific fixes, not a thumbs up. Every draft clears the bar before it reaches your feed.
Hook 5/10: Your opening is generic. Lead with the “3 days vs 3 months” comparison from paragraph 2 for an immediate contrarian punch.
Your human edits push this score higher. Keep going.
Funnel Balance
Authority is 5% below target. Too many hot takes, not enough depth.
Pattern DetectedYour highest-converting post was a founder lesson, but you’ve been posting mostly hot takes. Shifting to Authority content will drive more inbound calls.
Draft from “Implementation speed is the real moat” using an Authority angle. This closes your Product Engineering pillar gap and balances your funnel.
Every Post Maps to Your Funnel.
Sage tracks your funnel balance, spots what’s driving results, and tells you what to write next, and why. No more posting 5 hot takes in a row and wondering why nobody books a call.
