Unless you have some other reason for caring about these specific buckets, I'd go with: 0-25k (stipend, student, unemployed) 25-50k (part time, early career, or founder) 50-80k (junior person or early employee, maybe founder) 80-110k (most early/mid career individual contributors, non-technical managers) 110-150k (senior individual contributor or management) 150k+ (specialist, management in larger company, or successful founder in later stages)
