Manage your group meeting time
Deciding meeting date, time and venue is a ridiculously time-consuming and unproductive task. InterSec automatically picks commonly available timeslots from the calendar of you and your friends, and lets every participant vote on the date, time and venue.
This is my first startup idea, and a failed one. We didn't have enough passion for the idea so the project was given up even before the finishing of a MVP. But it's still a very good experience overall and marks my first attempt to launch a startup.
