Why this problem

Most donors give once and never come back

Nonprofits work hard to win a first gift, then lose most of those donors within a year. For a small team, that means starting from zero every campaign. We chose this problem over three other ideas because it is large, it is fixable, and the data to fix it is already sitting in every Givebutter account.

Why it matters

Four reasons this is worth fixing

The money is already thereEvery donor in your export has already said yes once. Keeping them is easier than finding someone new, yet most small teams spend their energy on the next campaign instead of the last one's donors.

Churn is silentNobody unsubscribes from giving. A card expires and a monthly gift quietly stops. A loyal donor skips a year. By the time anyone notices, it's year-end and the relationship has gone cold.

Small teams don't have the timeAt a nonprofit with one to five staff, the person who owns fundraising also runs events, the website and the board pack. The data is in Givebutter, but turning it into a list of who to contact, and what to say, takes hours they don't have.

A small action goes a long wayA personal note to the right donor at the right moment is one of the simplest ways to keep a donor. The hard part isn't writing it. It's knowing who, why, and when. That's the part Donor Radar does.

Why this, and not the other ideas

We weighed four options. One ticked every box.

The Spread offers seven playbooks, from launching a campaign to setting up recurring giving, plus a Wildcard for your own idea. We sketched four ideas, matched each to its closest playbook, and scored them against five questions.

Wildcard: Bring your nonprofit's idea to lifeChosen

Donor Radar

Big, measurable problem
Uses data every org already has
Useful every week, not once a year
Buildable in 24 hours, no API access
Shows its value in under a minute

The only option that hit every criterion. Retention is the biggest leak in small-nonprofit fundraising, the transactions export already holds the answer, and the output is a list someone can act on this Monday.

Launch a fundraising campaign in an afternoon

Campaign launch kit

Big, measurable problem
Uses data every org already has
Useful every week, not once a year
Buildable in 24 hours, no API access
Shows its value in under a minute

Generate campaign page copy, emails and social posts from a goal. Easy to build, but general AI writing tools already do this, it ignores the org's own data, and many teams were likely to build the same thing.

Design a smoother event journey

Event post-mortem

Big, measurable problem
Uses data every org already has
Useful every week, not once a year
Buildable in 24 hours, no API access
Shows its value in under a minute

Turn ticket sales into insights and pricing for the next event. Useful, but only for orgs that run ticketed events, and only a few times a year.

Wildcard: Bring your nonprofit's idea to life

Giving Wrapped on its own

Big, measurable problem
Uses data every org already has
Useful every week, not once a year
Buildable in 24 hours, no API access
Shows its value in under a minute

A shareable year-in-review for each donor. Fun and demoable, but a thank-you card alone doesn't stop donors from lapsing. We kept it as a feature inside Donor Radar instead.

Our playbook

Wildcard: Bring your nonprofit's idea to life

The Wildcard asks teams to pair their Givebutter data with an AI tool and build a useful first version of their own idea. Its list of example builds includes "weekly lapsed donor lists", which is the heart of Donor Radar. It also borrows from two other playbooks: finding recurring giving prospects, and turning donor data into a plan.

Givebutter data plus an AI toolReads your Givebutter transactions export and uses Claude to draft each email. We use the export, not a live connection, so the prototype can never change your data.

Something your team can run againThe weekly routine, the rules and the exact prompts are written down, including a version for Claude or ChatGPT. See how to run it again

What we built, and what we didn't

A Monday to-do list, not another dashboard

Upload a Givebutter export and get four short lists, in the order to work through them: monthly donors at risk, donors ready to go monthly, donors who lapsed last year, and champions to thank. Every donor comes with a reason and a drafted email you can edit and send.

No login, no CRM to set up

Your file is read in the browser and never stored

Clear rules you can check, not a black-box score

AI only writes the first draft. You decide what gets sent

Where the idea comes from

Consumer marketplaces live and die by retention. The same playbook works for donors.

Spot who is drifting, find who is ready to commit, thank your best supporters. Donor Radar packages that playbook for a team with no data analyst and an hour a week.
