# BRIEF 6 — Growth case studies (BIP / startup X)
**Angle (b):** accounts that grew hard in 2025–26 **or** consistently clear ~50k+ views/post  
**Scope:** research only · prefer Brief 1 BIP list · web + fxtwitter first · X API unused this pass ($0 of $3)  
**Depth over breadth:** fewer fully evidenced cases (weebo: real view numbers > shallow 15)  
**Marks:** `[MS]` multi-source · `[SS]` single-source · every metric row cites a status URL
### Fit keys
- **A** = follower climb evidence for ~2025–26 (esp. from small → 10k+)
- **B** = consistent / repeated ~50k+ views on originals (fxtwitter `views` and/or playersells median)
