Choosing the right entry model into lead generation determines everything that follows. We examine six distinct paths: affiliate publisher (lowest barrier at $5-10K), direct generator ($25-100K), vertical specialist, technology-first platform builder ($50-500K), service provider, and buyer-side entry. Each model carries different capital requirements, risk profiles, and timeline expectations ranging from 3 months to 3 years for profitability. Success depends on rigorously matching your entry model to your specific capital, skills, risk tolerance, and long-term goals. It covers vertical selection criteria including market size, regulatory complexity, and buyer accessibility. The discussion highlights that entry points should be viewed as launch trajectories rather than final destinations, with common progressions from affiliate to direct generator to vertical specialist as operators build proprietary knowledge and defensible competitive advantages.
