Justin Welsh’s Saturday Solopreneur is a free, weekly newsletter, and it’s become a must-read for anyone building a one-person business. Each Saturday edition delivers a single, laser-focused tip on audience and revenue growth. The advice is straightforward, rooted in Justin’s own experience as a solopreneur (he’s built a multi-million dollar one-person business himself), and most importantly, actionable. You won’t find any fluff or filler, just quick insights (each issue takes ~4 minutes to read) that you can put to work immediately to grow your business. He covers everything from mindset shifts (like why “willpower is a lie”) to tactical tips on monetizing your expertise, and always ties it back to practical steps you can use. It’s like getting a mini playbook in your inbox every week. If you’re a solo founder hungry for guidance but short on time, The Saturday Solopreneur is absolutely worth hitting that subscribe button.
