What Chorus does
Marketing intelligence that translates into measurable fundraising lift.
Right message. Right ask. Right person.
Chorus builds a preference profile for each supporter and routes them to the content they’re most likely to act on.
Answers in minutes, not months.
Propensity scores, LTV models, and audience segments on demand — through a natural language interface.
Spend less, raise more.
Concentrate investment where it performs. Cut your telemarketing list to the people worth calling and your SMS list to the people worth messaging.
We don’t just tell you what to do — we do it.
Upload your draft, then we cut the list, match content to segments, and pre-load into your send platform.
Most AI tools tell you who gave last year. We predict who will act on what you're about to send.
Content-aware prediction.
We analyze content, topics, themes, subject lines, tone, and ask framing alongside behavioral data. Non-obvious, actionable insights — not a restatement of what any experienced fundraiser already knows.
Automation, not just analytics.
Targeting lists, ask optimization, content-to-segment matching — pre-loaded into your send platform. The hard part of execution happens automatically.
Works with your stack.
Action Network, EveryAction, Engaging Networks, Mailchimp, Salesforce NPSP, Raiser’s Edge NXT, Luminate Online, and custom API. We sit on top of whatever you’re already using.
+1.1 million additional petition signatures.
Same sends. Same list.
We analyzed 79M email sends across 1,300+ campaigns from a national advocacy organization. Matching each subscriber to the petition they're most likely to sign significantly lifted engagement. By creating multiple petition options a day, we project +18% more clicks and 1.1M more petition signatures per year. No additional send volume. No clunky list cuts.
