Do you have a big ticket item or two that you only use part-time? We are living in an age of “peer sharing” which has opened a door to earning income from renting everything from RVs (Outdoorsy) to sailboats (see Sailo). This works for smaller items, too. KitSplit lets you lend out professional cameras. If you have a desirable item that costs more than the average person can afford, someone out there may be willing to pay to borrow it.
A website called AchieveMint gives you points for engaging in healthy activities, like exercise, tracking your eating habits, or even taking health related surveys. Points can be redeemed either for cash (10,000 points are worth $10) or for Amazon Gift Cards. The app actually connects with other health apps, like Fitbit and MyFitnessPal, to track your progress.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
