As your team fights minions, mercenaries, and heroes, the team gains experience and levels up. Level 20 is the last level you gain any new talent abilities, but your team can keep leveling up beyond that.
What is the maximum level your team can achieve during a match?
All I could find was an old article claiming the max was 25, but that's clearly not correct anymore. I just finished a 40 minute game and my team hit level 28, with the experience bar still increasing:

The maximun team level for now is 30,
You can verify this by going to the shop try out a hero and using the second button from top right you can level up your "Team" until reaching the maximun of level 30.
xerido posted the right answer, but I thought it would also be helpful to have an experience chart. Ahli from reddit has data-mined the team level experience requirements, for anyone interested:
