Most helpful for me personally, is the ability to coordinate more than 150 people with one task, not doing same thing 20 times as before (okay I am exaggerating it a bit, it was just twelve, but still, makes the point). We were using an Excel to make program more fun for youngsters (we created there more than 50 small tasks for them to do) and it did, no doubt. After we started using Zelos it reduces our time of creating them (now do not have to copy paste task for each team, but can just click and send it to all groups) but it increased the people who are doing it dramatically as well. Before there were active around 20-30% of the group, now around 75-90% percent. Of course there are still many bugs at the same time customer service is fast and tailored so we get answers fast that again helps to reduce stress of having the bugs with a big team.
