0 to 200 Users in 3 Days with $9 (My Claude Code + TikTok Playbook)

I went from almost zero users to ~200 in 3 days with my app Beads, with $9 of ad spend. Here's the exact playbook: find a niche, build the features they're begging for with Claude Code, then promote them on TikTok. Try 6to9 on your product: https://6to9.ai The playbook: 1. Pick a niche user segment (for Beads: grad students and researchers) 2. Find the gap: what they complain about in the apps they already use 3. Turn those complaints into specs, build with Claude Code 4. Demo the features on TikTok, boost the winners ($9) Chapters 0:00 0 → 200 users in 3 days for $9 0:54 The app: Beads (research papers → audio lessons) 1:59 Demand-driven ideas: niche → gap → spec 3:09 Step 1: Pick a niche user segment 3:59 Pricing and positioning against existing apps 4:43 Step 2: Ideas grounded in real user complaints 5:28 Idea 1: Dense Math & Jargon Translator 6:27 Idea 2: Tap your earbuds → flashcards 7:22 Step 3: Build it with Claude Code (MCP) 8:12 Ship and test the new feature 9:02 The TikTok + $9 boost playbook If you're building with Claude Code or vibe coding and stuck at zero users, this is for you. #startup #buildinpublic #claudecode
