For your tech team

The technical bit.

Everything your web, IT or data lead needs, in one place. If you're a fundraiser, you don't need to read this: just forward the page.

What your team actually does

Three steps. One of them is code.

1
Add one line to a page

Any site that lets you paste HTML: WordPress, Wix, Squarespace, Drupal or hand-built. About an hour, once.

2
Tell us the page address

We print it on the letters and emails, so supporters land on your page.

3
Get the results

Download each list as a file for your CRM, or use our API to send your declarations wherever you need them, automatically.

Security at a glance

Safe on your site.

✓
Runs in its own box
Foundry runs in a contained box on the page you choose. The rest of your site is unchanged.
✓
Only the right supporter gets in
A supporter needs details from their own letter or email before anything shows.
✓
Checked before it runs
Your page only ever runs Foundry's own, unchanged code.
✓
Works with your security settings
Foundry fits standard website security settings. Your team gets the exact settings once your charity has an account.
✓
Nothing on your pages
Everything about a supporter stays inside the Foundry box. Your pages and address bar never show it.
✓
Only what's needed is kept
Only the reference, name, address, email (if they've agreed to email) and first-gift year. Rows we hold back, and your file itself, are not kept.

The full technical detail (security, hosting, how data moves, and our API) is shared with your team once your charity has an account. Data protection and contract questions: talk to us.

Your data

Your data, protected.

Foundry launches in November 2026. These protections are built and tested today.

Each charity locked to its own records
Every charity's data is kept apart from every other charity's, at every level. Your sign-in only ever sees your own records.
Evidence that can't be rewritten
Every declaration keeps a record of exactly what the supporter saw and agreed to, and it can't be changed afterwards.
Encrypted, and not on the open internet
Data is encrypted in transit and at rest, and our database is not open to the internet.
Stored in London
Your data is stored in London on Google Cloud. Encrypted backups are kept in the UK and the EU.
Backed up every day
Daily backups, with restore to any second in the last 7 days. We test restores.
Supporter codes protected
We never keep a supporter's code in a form that could be read back, and nothing shows until the supporter's details match.
Protected against guessing
Repeated wrong attempts are blocked automatically.
Multi-factor sign-in for your team
Charity staff sign in through Frametric with a second factor. Every bulk export asks for a recent second factor too.
Every view and download logged
Who, when and what, for every download and every view of a full record. Supporter addresses show masked on screen.
CRMs
Works with yours

Foundry works with any CRM: download a file, or use our API to send your declarations wherever you need them, automatically. Cascade already works with Salesforce, Blackbaud, Microsoft Dynamics, Donorfy, Access, Advanced, SugarCRM and spreadsheets.

More detail
Supporters, gifts and declarations flow into Cascade from the system you use today. System not listed? Talk to us.
Declarations
Evidence built in

HMRC's model declaration wording, one box the supporter ticks themselves, a confirmation by email when the supporter has given one, and an evidence record for each declaration.

More detail
Foundry Vault keeps the web declarations you already hold in one place, each with the original record of how it was made, ready for when HMRC asks. Verbal declarations follow with Foundry Voice.
Your data
Always yours

Every declaration Foundry collects belongs to your charity, always. Every figure in Cascade traces back to the records behind it.

More detail
Upload a CSV of the supporters you want to ask, from any CRM. Every row is checked before anything is made, and rows held back come with the reason.
