EXP vs C21 vs Berkshire Hathaway - does market presence matter?

[Spence Kal]

Hey everyone, My question is, does it matter if brokers/team leaders have been in the market for 30 years, and is it a risk to join a team that's fairly new? Will my success be hindered by joining a team with less market share, or is it all on me to make it no matter where I go?

For a little back story, I just finished all my classes for my real estate license, and I'm in the process of signing up with a local EXP team in my area. I've interviewed 7 brokerages and multiple teams, and really like the feel of this local team, their office environment and obviously the EXP model. My concern is that the team leader has only been selling for 6 or so years, the last 2 with EXP, they don't have a huge amount of listings, and I don't see a lot of EXP signs in my area. The local century 21 and Berkshire Hathaway brokers/team leaders have been in the area 30 years, and the companies have a larger presence here. Obviously they have far more agents. I'm just concerned that I may not do as well because the local team and EXP don't have as much market share as C21 and BHHS, is that stupid to think I would be more successful under a team leader whos been here 30 years.
