The Full Story
Soy un ingeniero de software de 29 años de Alemania que dejé mi trabajo de tiempo completo para dedicar un año a construir mis propios proyectos.
La lucha
Mi crecimiento de MRR tuvo fases de estancamiento - el salto de $6,000 a $7,000 tomó 2 meses, y de $7,000 a $8,000 tomó 5 meses.
El avance
En junio de 2024, gané el concurso Times Square de RevenueCat. Luego el canal de MKBHD presentó HabitKit en un video que llevó a un pico enorme.
- Tiempo a $10K MRR: 2.5 años
- Experimentos de pricing desbloquearon crecimiento
- La presentación de MKBHD cambió todo
Key Takeaways
1
El crecimiento no es lineal - sé paciente durante períodos de estancamiento
2
Establece un deadline ajustado para el MVP - me di a mí mismo 4-6 semanas
3
Los experimentos de pricing pueden desbloquear nuevo crecimiento
4
Una característica grande (como Times Square o MKBHD) puede cambiar todo
