Write tasks

Many non-devs think developing an app is only about coding. No, it's not!

• Who stays in touch with stakeholders?
• Who makes sure everything is legal?
• Who is responsible for testing and will find testers?
• Who cares about marketing and those social media accounts?
• Who looks for new colleagues once we need new skills?
• Who controls the budget?
• ...

Of course, a dev could do all this too. But a dev shouldn't waste his time for those tasks. There are plenty of features to build which only devs can do!

BTW: I recommend trello.com for writing up and displaying tasks to your colleagues.

Select tasks for the next Sprint

The most annoying thing is when someone starts talking about tasks which are absolutely unimportant at the moment and you cannot even stop him.

By selecting the tasks you avoid those unnecessary conversations and only discuss what's selected.

Assign tasks

Devs are energetic people and love coding. Isn't it annoying when you expect other colleagues to work as hard you but they don't?

By assigning tasks everyone commits himself to do it and knows other colleagues expect this.

Conclusion

Personally I think the team is the most important thing in a startup. By keeping an eye on those three advices you know from the start how well the team will perform. Finally, you know if the startup project is worth your time or not.
