What Donorfy actually is
Donorfy describes itself as a charity CRM, a "Constituent Relationship Management system." Its stated features are contact management and supporter segmentation, donation processing and Gift Aid automation, campaign and event management, email communication, and reporting dashboards, with integrations including JustGiving, Dotdigital and Stripe. It is built for the fundraising team’s internal record of who gave what, and for running campaigns off the back of that data.
What Impacturi actually is
Impacturi does not process donations, Gift Aid or campaigns. It takes a donation a charity has already recorded and turns what it paid for into a branded Impact Page shown to the donor, built from a corporate or individual template depending on donor type, generated from a few bullet points the charity uploads. Alongside that, it tracks renewal dates so nothing slips, keeps a lightweight record of donors, companies and event attendees for retention purposes, and compiles everything a charity has published over the year into a board-grade PDF report for trustees or a specific corporate sponsor. It is built for the relationship after the gift is recorded, not for recording the gift itself.
Where the two do overlap, honestly
Impacturi does keep its own donor records, so there is a genuine area of overlap with what a CRM like Donorfy does. The difference is depth and purpose: Donorfy's donor records exist to run Gift Aid and campaigns across an entire supporter base. Impacturi's exist to know who an Impact Page was built for, when they are next due an update, and what to put in the board report. It is not built to replace a full constituent database, and most charities running Impacturi keep their existing CRM as the system of record for donations.
So which one does a charity need
Most charities that already have a CRM like Donorfy are not missing a database. They are missing what happens after the donation is logged: a donor-facing Impact Page that shows the gift meant something, a way of knowing when to send the next one, and a straightforward route to the board report at year end. A CRM does not produce any of that on its own, it is not built to. That is the actual gap Impacturi fills, and it is why the two are not competing for the same job. A charity using Donorfy for its records can add Impacturi for what donors actually see and when they hear from you again, without replacing either tool.
The honest answer if you are choosing between them
You are not choosing between them, you are asking two different questions. "How do I record and manage donations, Gift Aid and campaigns" points to a CRM like Donorfy. "How do I show every donor what their specific gift did, keep track of when they are next due to hear from me, and get to a board report without starting from scratch" points to Impacturi. Most UK charities losing first-time donors have the first question answered and the second one open.
