Chamberly is live: sponsorship software built for chambers of commerce

As of May 1, Chamberly is generally available. If you run events and sponsorships at a chamber of commerce, it's built for you, and only for you. That's on purpose.

This post covers why we made a sponsorship platform just for chambers, where it came from, and what's in version 1.0.

Why a chamber-specific platform?

Chambers sell sponsorships differently than almost anyone else. A nonprofit gala has one event and a list of donors. A conference has exhibitors and a booth map. A chamber has something messier: a whole calendar of events, a membership that buys across all of them, returning sponsors who expect to keep "their" sponsorship year after year, and a staff of three people who also run the ribbon cuttings.

The general-purpose tools don't handle that well. Membership databases usually treat sponsorships as a line item on an event. Ticketing tools don't know what first right of refusal is. Spreadsheets know everything, as long as the one person who maintains them is in the office.

So most chambers end up with a patchwork: a PDF sponsorship guide, a spreadsheet of who bought what, an email thread for each renewal, and an invoice created by hand in the accounting system. It works, mostly. It also means a lot of sponsorships get sold by phone tag, and some don't get sold at all because nobody got around to asking.

Chamberly is meant to replace that patchwork with one place where your members can see what's available, claim or buy it, and where your staff can see everything that's been sold, held, or promised.

Where it came from

Chamberly didn't start as a blank page. It started as a WordPress plugin that chambers were already using to sell sponsorships on their own websites. That plugin taught us a lot about how chambers actually work: how first rights get negotiated, how tiers get named, how often a sponsor wants to pay by check instead of card.

It also hit the limits of being a plugin. Every chamber was running a different WordPress setup, updates were fragile, and features like automated renewal emails or a proper sponsor leaderboard were hard to do well inside someone else's site. So we rebuilt it as a hosted platform, keeping what chambers liked and dropping what they didn't.

What's in version 1.0

A branded storefront for your sponsorships

Every chamber gets its own sponsorship storefront, styled with your colors and logo. Members can browse by event, filter to what fits their budget, and see what's still available in real time. Each event gets its own public page too, so you can link straight to "Golf Classic sponsorships" from a newsletter. More on that at the storefront page.

Events, sponsorships, and exposure tiers

Create an event, attach sponsorships to it, and group those sponsorships into tiers (presenting, gold, silver, whatever you call them). Set quantities, prices, benefits, and go-live dates. See events and exposure tiers.

Online payments or reservations, your call

You can take card payments through Stripe, or you can run in reservation mode, where a member claims a sponsorship and you invoice them however you already do. Or both. You don't need Stripe to get started, which matters for chambers whose finance committee isn't ready for online payments yet.

First rights, handled automatically

Returning sponsors can be given first right of refusal on their sponsorship. Chamberly holds it for them during the window you set, sends the reminders, and releases it to everyone else when the window closes. No more "I thought you were holding that for me." Details at first rights.

Recognition that sponsors notice

A sponsor leaderboard can be turned on in five places: event pages, a standalone leaderboard page, the sponsor's own account, your dashboard, and your storefront home. Turn on the ones that fit your culture and leave the rest off.

Email built in

A block-based email builder, transactional templates for order confirmations and reminders, and automation recipes for the emails you send every year anyway. See email automations.

The rest of the basics

• Coupons, subscriptions, and plan-based features through Stripe Connect billing
• Reports on revenue by event, sponsorship, and time period
• CSV and Excel import so you're not retyping your member list
• A five-step onboarding wizard for your first login
• "View As," which lets you see the storefront exactly as a specific member sees it (more here)
• AI connectors, including an MCP endpoint and Chamberly for ChatGPT, if your team uses AI assistants

Who it's for

If your chamber sells more than a handful of sponsorships a year and any of these sound familiar, Chamberly is probably worth a look:

• Your sponsorship guide is a PDF that goes out once a year.
• You track first rights in a spreadsheet, or in someone's memory.
• Members call to ask what's still available.
• Renewals depend on someone remembering to send an email in January.
• Your board asks "how are sponsorships doing?" and the answer takes a day to put together.

It's probably not for you if you run one event a year with two sponsors. A spreadsheet is fine for that, honestly.

Pricing

We kept pricing simple: three plans, billed annually, no contracts. Core is $2,999 a year, Pro is $3,999, and Premier is $4,999. The differences are mostly about how many sponsorship slots you run and whether you need packages, automations, and dedicated support. The full breakdown is on the pricing page.

What's next

Version 1.0 is a starting line. We'll be shipping small improvements constantly and posting a monthly roundup here, plus a running record on the changelog. If something's missing for your chamber, tell us. The roadmap is shaped by real chamber problems, not a feature checklist.

If you'd like to see it with your own events loaded in, book a demo, or start a free trial and poke around.
