My Community Platform Member Ceiling

My Community Platform prices by member ceiling, not by seats: Launch at $150 monthly ($125 annual) caps at 5,000 members with 50,000 emails, Growth at $900 monthly ($750 annual) raises that to 10,000 members and 150,000 emails, and Scale at $1900 monthly ($1583 annual) reaches 25,000 members and 500,000 emails. Native iOS and Android apps only appear at Growth and above. For an agency, the ceiling is the pricing event. A chamber of commerce at 4,800 members sits on Launch; one renewal season later it crosses 5,000 and the client must move to Growth, a 6x jump. Agencies that quote a flat retainer without mapping the client's growth curve absorb that jump themselves. Model the member trajectory before signing, and write the tier change into the retainer as a scheduled adjustment rather than an awkward mid-year conversation.
