A one-person portfolio of courses, sponsorships, and paid email products built on consistent LinkedIn and X publishing.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Justin Welsh runs a knowledge business alone, reporting about $1.7 million in revenue last year and anticipating around $2.5 million this year. The portfolio has three parts: courses on using LinkedIn to build a business and on building a content system, sponsorships in a newsletter approaching 100,000 subscribers, and a paid monthly email about copywriting for social media. He says the business costs about $620 per month, including a $399 Kajabi subscription and several publishing and workflow tools. He does not spend on paid ads and rarely uses contractors. Distribution comes from posting on LinkedIn and Twitter two to three times daily, then moving interested readers toward longer articles and a weekly newsletter before presenting offers. Before going online, Welsh was a technology sales executive. After burnout, he began building an audience around topics he cared about and knew well. The case is a reference for expertise-led publishing, but it depends on sustained writing and trust rather than a software moat.
