Interesting that they're doing this for new grads.

I've thought about whether you could have a site like this for experienced teams.

Lots of people stay at employers that suck, because they like their teammates and don't want to let them down. I think it would be a game changer if experienced teams could jump ship in one go. It would certainly benefit the new employer as the cost of hiring would be less, and the time to getting productive would be less. From the employees side, a company that's in the market for an entire team is an attractive prospect, since it's likely to be in a growth phase and well funded

Informally, it's not that rare for a complete team to leave a company and all, or mostly, end up at the same new employer. But formally lots of people have non-solicitation clauses and it may also be some kind of tort to invite people to violate them. But I do wonder how easy or hard such a site would be to legally defend.

That would be the kind of 'disruptive innovation' I could get behind: changing the balance of power and making people's lives better.
