sidething
Think of sidething as the Duolingo for side hustles. Every single member gets a personalised AI roadmap, weekly check-ins, streak tracking, coaching, and accountability built into the product. You open the app, you see what to work on, you do the work. Other communities and programs are what you make of them. sidething gives you structure, strategy, and momentum from day one.
The virtual HQ is where co-working sessions, inner circles, and events happen. It's a buzzing office full of people building, not a forum thread. Membership is application-only, so everyone in the room is shipping. The app works for any business type: SaaS, newsletter, coaching, e-commerce, AI products, services.
Startup School
Startup School is Y Combinator's free online program. The curriculum covers startup fundamentals: how to get ideas, talk to users, build an MVP, measure traction, and grow. The lectures are from YC partners and successful founders. It's genuinely excellent educational content.
The program runs in cohorts with group sessions and a community forum. You get access to YC's co-founder matching tool and some partner deals. It's completely free, which makes it one of the best entry points for anyone new to startups. The trade-off is that nothing is personalised to you or your business. It's general startup education, not a tool that adapts to what you're building. Once you've watched the lectures and done the exercises, you graduate and move on.
