When looking for partners or employees it’s common to settle for B talent because they are the best who have applied or shown interest.
Personally, I would rather have no help, or no partners then B level talent helping me. Sometimes you have to settle on other things such as compensation, location, or something else but don’t settle on talent.
If you want an A operation, then find A talent. If you settle for B talent, you will be fortunate to get a B operation and have little hope of ever getting to the A level.
Have a great day!
