I'm in Los Angeles and despite my proximity to BB I have avoided BrandBucket all these years.
Why?
It just smells so bad to me at Brandbucket.
Smells like they take too much of your money on a greedy commission schedule.
Smells like they take too many of your marketing choices away via exclusivity.
Even smells like the principals might be fooling domain sellers by buying their names for $3k now...so they can resell them later to end users for ....$8k? $12k? More?
I feel you, I was contacted by guy close to new would be startups. He told to me he even negotiates the price with BB buy the domain name for 2.000 - 3.000 USD and resell them later for 2-3 times higher prices. This was his advantage for being close to would be startups and their fundings. Ive heard people increased their sales with their own marketplace, I see this especially tempting for a guy with 900 published names who sold only 1 in 2 months time. But I have to admit I like their selection procedure, so even when I make my own marketplace when having 1000+ names, I would like that they are ok.
Good luck to all.
