Bloon makes it easier to organize spontaneous group activities like basketball or happy hour. Activities organized with Bloon only happen once a critical number of friends respond that they are interested, and attendees are then put in a group chat to finalize plans.
I conceptualized, built, and launched Bloon on my own. As the sole founder, I was the product manager, designer, engineer, and everything in between. I put together the presentation on Bloon below if you're interested in learning more about the product and to give a brief overview of what I did.
I also did some writing on what I've learned while building Bloon here.
