That's the whole game. Meet the partner, get the juniors, pay for the partner. And if you're really unlucky you can spend your time educating the juniors.
Less cynically: there is only one partner; the team, if it works, manages to leverage the partner to ~5x - 10x.
And no, you don’t pay partner rates. The client generally knows that to do commercial pressure you need to get info about team size, put it in the contract, and then negotiate on blended rate so it is close to what the market pays for the junior.
