Can I offer a program to a group of clients from various organizations?

Yes! It could work in a few ways:

• As an invite-only program: if it is marketed to up to 1,000 people total and has no more than 30 participants, it can be an invite-only program. The pricing is flexible for this, so it can be an easy way to bring together groups from multiple organizations. 
• As a client program: One client can host the program, and each client contributes to the total program fee based on the participants. 
• As a public program: this could be a public program if it adheres to the requires of a public program (e.g. pricing, co-teaching, venue etc.). This is a good option if you want to publicly advertise the program.
