How many times have you thought to yourself: Wow, if everybody could just pitch in $1 dollar, we'd have enough to fix this problem? Well, that was the genesis of PIFster! And now we're so proud and excited to present to you this app, representing a 501(c)(3) non-profit (pending), which empowers a growing community of like-minded individuals to donate as little as $1 dollar per month, and then suggest and vote on a diverse slate of charitable causes. PIFster is totally free to join and explore. The only thing required is that you actually donate in order to vote on which charity will be the recipient of our community's collection each month. That's fair, right? Just put a little skin in the game. After all, a dollar is barely pocket change these days, but if we ALL chipped in... well, you get the idea. So that means 12 times per year you can Pay It Forward! Grow a community of your own and increase your influence! On your journey, watch videos documenting the good we've done as a community, and swell with pride at being a part of something so unique and special. PIFster is also a great place to both suggest and promote charitable causes near and dear to you! And anybody can do that, whether they have the financial resources to contribute, or not. If nothing else, please join to let us know who you feel deserves a helping hand! Want to see where the community is most active? Explore an interactive "heatmap" showing the relative number of either donors OR donations within an area! Want to drill down even deeper? You can explore the relative activity of those in your own personal community! As you can see, PIFster is the perfect tool for influencers to leverage their followers for good! So join the PIFster community today! Let's start making the world a better place $1 dollar at a time!
