Applying to incubators takes time, time that you will not spend working on your business. In order to minimize this, I suggest you :
- go over the submission papers of the 2-3 choices you are interested in (either download them or ask the incubators) ;
- fill them out (copy/paste is your friend) and submit them. Don’t forget to prepare a PIA form if you’re eligible too ;
- plan out meetings with the incubators to discuss your project ;
Applying to several incubators at the same time will make things faster and will offer you a cushion of safety in case you get rejected by one of them. If you do get rejected by 3 incubators it might be wise to reevaluate your project. Or not.
