Perry Chen, co-founder and former CEO of the seminal crowdfunding site Kickstarter, has dreamed up another way to mobilize people to make something happen. His new project, Dollar a Day, is an email newsletter that features one nonprofit organization on a daily basis. Subscribers can sign up to become donors and send a dollar a day to each chosen organization. Then, Dollar a Day — which itself is a nonprofit organization — bundles together the money and sends it off to the recipient. “We had this mantra of what is the simplest, smallest thing that could have a really big impact,” Chen said in a phone interview last week. “I think there’s a lot of good intentions, and I think people don’t know which organizations to support and don’t have the time to do their research. It’s a small bridge between the intention and being able to take more action.” Dollar a Day is probably one of the least hardcore startups out there.
