Multi-vendor marketplaces, like ThemeForest, can be very successful. Chose a niche and create a vendor website for it. Your marketplace could be anything, from a platform for local artists to sell their work on, to an online digital product store. Once set up, invite people in that industry to sell their products on your site. You take a percentage of their profits when items sell.
Build your audience on a course community: If you’re just getting started building an audience for yourself and want to leverage communities already actively looking for content you can choose to host and sell your online course on a site like Skillshare or Udemy. These are easy, cost-effective ways to build an audience and test your niche to see if there’s demand for it.
Online savings accounts usually come with crazy good interest rates to help you grow your money faster (regular in-person banks can’t offer rates as high). We’re fans of CIT Bank and Discover Bank (among others) because their interest rates are often over 25 times the national average. That means the money in your savings account will grow 25 times faster than the pace it’s most likely growing at now. Really, though, you can’t go wrong with pretty much any online savings account that offers over 1.50% APY 🙂
