Justin Welsh runs one of the most-studied solopreneur businesses on the internet — a multi-million-dollar, one-person operation with no full-time employees. A huge part of his appeal is how openly he shares the lean, no-code tech stack that makes it possible; he's published it on his own site and tweeted versions of it many times. Below is a breakdown of the tools he uses, with cheaper alternatives. (His stack has evolved over the years and tools change, so treat this as a current snapshot, accurate as of mid-2026.)

Justin's guiding principle is worth stating up front: keep it lean. He's famous for showing that a tiny monthly tool budget can run a business doing seven figures a year. The point isn't the specific apps — it's resisting the urge to over-tool before your business justifies it.

Website and courses

Justin runs his courses and much of his web presence on Kajabi, an all-in-one platform for selling online courses, hosting content, and handling payments. Notably, when he started out he used Carrd — a website builder that cost him about $19 — which he often cites as proof you don't need expensive infrastructure to begin.

Email and newsletter

His newsletter, The Saturday Solopreneur, reaches a very large audience and is the engine of his business. He's used ConvertKit (now Kit) as a core email platform, and has also used Beehiiv for newsletter publishing. The throughline of his advice: own your email list, because it's the one audience asset no platform can take from you.

Social scheduling and publishing

Justin built his audience primarily on LinkedIn and X, and he leans on scheduling tools to do it without living inside the apps. He's used Hypefury for scheduling and recycling posts, and Taplio for LinkedIn scheduling and analytics. These let him batch content and stay consistent — the real driver of audience growth — without being permanently online.

CRM, automation, and analytics

The back office of Justin's business is deliberately simple. He uses Notion as a personal CRM and for project management and process documentation, Airtable for structured data, and Zapier to wire his tools together with no-code automations. For website analytics he's used Fathom Analytics, a privacy-focused alternative to Google Analytics. He's also used Typeform for forms and surveys and Gumroad for selling digital products.

How to copy his setup

The honest takeaway is Justin's own: start far smaller than you think you need. A Carrd site, a free email tool, one scheduling app, and Notion to keep yourself organized is enough to begin — that's close to how he started. Add tools only when a specific one will clearly save time or make money. The leanness isn't a constraint; it's the strategy.
