Strategy and Growth
- Positioning
  - Targets the makeup niche identified via high-volume TikTok hashtags, solves unmet demand for low-friction makeup try-ons
- Primary growth engine
  - Organic TikTok content, viral video engagement loops, direct App Store anchor links
- Key tactics
  - Idea validation: Analyze TikTok comments in target niche to identify unmet demand, create content before building to confirm market fit
  - TikTok account warm-up: Use US-based SIM or 24/7 US VPN, engage with niche content 15-30 minutes daily for 3 days to avoid bot detection
  - Content strategy: Replicate trending, faceless niche content; post 1x daily initially, scale to 4-6x daily after gaining traction
  - Anchor links: Add direct download buttons to videos with >100K views (earlier use kills reach) to drive seamless App Store traffic
  - Scale content: Run 2-3 accounts per phone, up to 7 accounts posting 8-12x daily at peak
  - Viral referral loop: In-app incentive (free makeup look for 3 invited friends) drives users to comment referral codes on TikTok videos, boosting engagement
  - Paid growth: UGC and influencer marketing effective but high-cost; prioritize organic content if budget-constrained
Tech Stack and Infrastructure
- MVP development: Flutterflow (drag-and-drop Flutter-based tool for rapid development)
- Backend: Firebase, Google Cloud Functions, external APIs, Firebase database
- Payments: Superwall
- Event tracking: Mixpanel
Lessons and Advice
- Take action before you feel ready: Move first, adjust later; avoid waiting for perfect timing, learn fast from mistakes and successes
- Consistency wins: Keep building and grinding, focused effort will lead to long-term success
- Niche expertise is optional: You do not need to be passionate or an expert in a niche to build a profitable business; treat it as a capitalistic endeavor
- Pre-launch marketing beats post-launch: Validate demand via content before building, avoid building products without confirmed user interest
