Live pilot · Dansk Røde Kors v01 / 2025

Contact the
people who will
actually say yes.

We score every contact in your next campaign with a gradient-boosted model - so your direct mail and outreach budget only goes to the audience most likely to respond. Same revenue, a fraction of the spend.

We ingest your data.

Existing customer or donor records - purchase history, engagement signals, demographics - cleaned and assembled into a feature set we can train on. SFTP, CSV, or warehouse export.

~1–2 weeks · zero engineering on your side
2 MODEL

We train a classifier.

An XGBoost model fits on your historical conversions. Output: a probability score for every contact in your next campaign audience. We share feature importance so the model isn't a black box.

3 TARGETING
τ

You send to the top slice.

Pick a threshold based on your CPM and expected conversion. Mail or serve ads only above the cut-off. Same fundraising or revenue, fraction of the print, postage, or media spend.

§ 02 - Who it's for

Anyone running volume
campaigns where every contact
has a cost.

If you're paying per recipient - postage, print, ad impressions, calls - and most of them don't convert, scoring before you spend pays for itself in the first send.

NGO fundraising

Donor mail-outs, newsletters, recurring-gift upgrades. Cut volume without cutting yield.

DONOR APPEALS · LOTTERY · TESTAMENTAL

Retail & loyalty

Catalogues, win-back coupons, churn campaigns. Predict the customers worth reactivating.

CATALOGUE · WIN-BACK · CRM

Political campaigns

Door-knock priorities, persuadable-voter mail, GOTV cohorts. Same field budget, more contacts that matter.

DIRECT MAIL · CANVASSING · GOTV

Subscriptions

Renewal letters, retention offers, free-trial conversions. Spend on the segment that's actually on the fence.

RENEWAL · RETENTION · TRIAL

First in production:
a humanitarian one.

PILOT ONGOING · 2025

Optimising donor campaigns for Dansk Røde Kors.

By scoring their donor base before each send, we identify which contacts are unlikely to donate in a given cycle - reducing print and postage costs without reducing fundraising yield. Same approach generalises to any organisation running volume campaigns.

Pilot is in flight. Results coming end of 2025.
