If you can increase the size of your sales team, you can get your solutions in front of more customers.
But hiring more people to your sales team can be expensive. But what if you could tap into your partner's sales team and have more feet on the street.
You can share your GTM activities with your partner's sales team and have another set of feet on the street to sell your co-solution.
I am all about maximizing & utilizing the available resources. When you are creating a co-solution, your partner also the vested interest in making it successful, they will be more than happy to empower their sales team as well to help sell the "co-solution."
So, don't hesitate to ask your partner, you will be pleasantly surprised.
