Two all-in-one chamber platforms. Here is how they compare on pricing, the website, the demo, mobile, sponsors and payments.
Reviewed November 2026 from each company's public website.
No form. No phone number. Resets nightly.
The short answer
Both run members, dues, events and a chamber website. Chamber Culture publishes its price, includes the website on every plan and lets you open a working demo chamber right now. It also offers an iPhone app, sponsor e-sign, a choice of payment processor and culture surveys.
Diagonal builds a version for your chamber before a booked demo and mentions committees on its site. If a guided, quote-based sale suits your board, it is worth a look.

How custom development works →Frequently asked questions
Is Chamber Culture an alternative to Diagonal?
Yes. Both are all-in-one chamber management platforms covering members, dues and invoicing, events and a chamber website. Chamber Culture adds published pricing, a website included on every plan, a self-serve live demo, an iPhone app, sponsor proposals signed online and culture surveys as an add-on.
How does pricing compare?
Chamber Culture publishes its pricing: $150, $300 or $500 a month by member count, with the website included and no contract. Diagonal does not publish pricing on godiagonal.com; it quotes one price by member count and prices the website separately (as of November 2026).
Can I try Chamber Culture without a sales call?
Yes. The live demo opens a working chamber admin console and member portal with no sign-up. Diagonal's site offers a booked demo, for which it builds a version for your chamber first.
Do both migrate from GrowthZone and ChamberMaster?
Diagonal says it moves your data during onboarding. Chamber Culture migrates from GrowthZone, ChamberMaster and other chamber systems using AI-assisted field mapping with a dry-run preview and one-click rollback, and hands you a redirect list so old links keep working.
What if Chamber Culture does not have a feature we need?
Tell us and we build it. Chamber Culture is built by Champlin Enterprises, a software company. Chamber Connect, Event Playbooks and sponsor e-sign all started as chamber requests, and work only your chamber needs is scoped with you and built.
