Investors invest for one thing and one thing only, return on their investment. How can a nonprofit startup that is trying to give back to the community raise any funds?
All existing funding platforms like Angel.co are geared towards for-profit companies. Are there any platforms where we could connect with philanthropists?
If one doesn't exist, that would be a great business itself.
Crowdfunding meets this need in many cases. Kickstarter, IndieGoGo, or any of the many platforms you can find by searching "kickstarter for non-profits" can help you raise funds without it being an "investment" that's expected to generate returns.
The more traditional route you should know about is grant-writing. And you should also know that large corporations like Google offer a ton of in-kind services that can save a non-profit money. Their AdWords for non-profits program essentially gives you a free $10,000 advertising budget each month.
