Tactics you can copy
- 01Cold-start on a freelance marketplace by taking jobs cheaply or free purely to accumulate reviews and logged hours, using platform credibility to win later work.
- 02Start broad in PPC, test Facebook Ads, lead gen and SaaS niches, then narrow to one wedge: e-commerce plus Google Ads.
- 03When scaling, replace task-based subcontractors with team members given roles, responsibilities and goals; the founder claims output shifts from 1+1=1.5 to 1+1=3.
