A Donation Engine built to help your cause raise more.

We're the complete digital partner for Australian charities — a Donation Engine on your own Stripe for 2.5% of donations, with your website included if you'd like us to run that too. We handle the tech, the testing, and the ongoing optimisation, so you can focus on your mission.

Why 3CK

4 things that make charities choose us.

Most donation platforms have you do the work yourself. Here's what changes when we do it for you.

Modern, fast architecture

More speed means more completed donations — every extra second of load time is a supporter who gives up before finishing their gift. Every site and Donation Engine we build is custom, edge-hosted, and fast by design. Other donation pages we've benchmarked score 12–62 out of 100 on Google's own Lighthouse speed test; ours consistently score 99–100.

No pre-selected tips, ever

Our fee is 2.5% of donations, and you're the one who pays it — openly. Donors are asked if they'd like to help cover the fees on their gift, but unlike the common pattern in this market that box is never pre-ticked and never pushed — a donor who does nothing pays nothing extra. It's their choice to make, not ours to assume.

Always improving, not just launched

We don't disappear once you're live. Your Donation Engine gets constant, automated testing and refinement — never a one-and-done launch — turning more visits into gifts, and more one-off donors into recurring ones. With AI-assisted reporting showing what's working, your cause keeps raising more, without extra work on your end.

Compliant, and genuinely Australian

Accessible by design (WCAG 2.2 AA), hosted in Australia, and built with the ATO/DGR receipting rules baked in. Built in step with Australia's incoming Unfair Trading Practices law on checkout dark patterns, with donor data handled under the Australian Privacy Principles — so your board can trust it, not just your donors.

Independent Google Lighthouse tests (mobile), July 2026, across six of Australia’s most-used hosted donation platforms. Individual pages vary and scores change over time — test your current donate page free at pagespeed.web.dev.

Client results

Real results for Australian causes.

Not mock-ups — money we actually helped raise, and a relationship that lasted years.

Case study · Sydney Eye Hospital Foundation

A donation flow that paid for itself — for years.

We built and managed their website, ran their Google Ad Grant — up to $120,000 a year in free Google advertising — and operated their donation flow for around six years: driving tens of thousands in online donations and transferring the money straight to their account (including a single $8,000+ payout). Tangible dollars they could see, not a service they had to take on faith.

The Donation Engine

Built to raise more —
without taxing your donors.

Most donation platforms charge 4–5% of every gift — and add a pre-selected donor "tip" at checkout to fund themselves — then leave your team to run it. We charge 2.5% of donations, and no pre-selected tips at your checkout — a donor who does nothing pays nothing extra. It runs on your own website and your own Stripe, and we

Your own Stripe

We take 0%. It's your money.

It runs on your own website and Stripe — every gift flows straight there. We never touch the funds, and 3CK never holds your money; Stripe's standard processing applies, same as any Stripe merchant.

EOFY tax nudge

Give more, for the same cost

At tax time we show donors their tax saving, and offer to give it forward — a bigger gift that costs them about the same.

1-click monthly

Turn one gift into monthly

The moment a donation is received, we thank the donor — then invite them to make it a small monthly gift. One tap, no re-entering card details.

Employer matching

Double it with their employer

After giving, donors check their employer. If it matches gifts, we hand them the exact steps — net-new dollars for your cause.

Automatic receipts

DGR receipts, done for you

ATO-compliant tax receipts are generated and emailed the instant a gift is made. No spreadsheets, no EOFY scramble.

Gift recovery

Win back the gifts that almost got away

We recover donations people start but don't finish — the compliant way: one gentle nudge, no pre-checked tips, no confirm-shaming.

Website Design

Keep your website, or let us run it too — your call.

Plenty of charities just need their donation page fixed, and that's completely fine — the Donation Engine stands on its own. If you'd rather we build and run your website as well, it's included in the same 2.5%, never an extra fee.

Free migration, not a fee

Already have a website you like? We rebuild it on our stack — free, no separate build cost — so nothing about switching to 3CK costs you upfront. Want something new instead? A full redesign is a straightforward, fixed one-off project.

Fast, accessible, done for you

Every site is custom, edge-hosted, and fast by design — around 2-second loads, WCAG 2.2 AA accessible, hosted in Australia. Updates and content changes are handled for you, never a DIY page builder.

Built to convert, not just to look good

Every page is designed around getting a supporter to your donate flow, not just looking nice — a beautiful site that doesn't lead anywhere isn't doing its job.

No extra cost either way

Whether you'd like us to run just your Donation Engine or your website too, it's the same 2.5% — no separate hosting bill, no separate build invoice, nothing itemized.

Everything, handled

One partner for your whole digital home.

One rate for your Donation Engine — and your website too, if you'd like us to run that as well, at no extra cost. Here's everything it includes.

Beautiful, fast websites

The Donation Engine

We build and run your Donation Engine — a fast, accessible donation page on your own website and your own Stripe — for 2.5% of donations, with no monthly fee, no setup fee and never a pre-selected donor ‘tip’ — plus EOFY gross-ups, monthly upsells and employer-match prompts designed to lift average gift size.

  • Ironclad security & daily backups
  • Ongoing testing to keep improving results
  • Ongoing accessibility monitoring
  • Priority technical support

One rate — 2.5% of donations — whether you use just the Donation Engine or your website too. The rate never changes as you grow.

Our story

We’re 3CK — short for Third Culture Kid.

It’s the name for people who grow up between worlds and build a new one of their own.

Meet Phoenix, our mascot: a blue-winged kookaburra with a Vietnamese-inspired name. Phượng means “phoenix” — after our cofounder Phuong. An unmistakably Australian bird carrying a story from somewhere else. Like us, he doesn’t fit neatly in one box. That’s the point.

We’re two Australians who live between two worlds too. Matthew brings the rigour of business and legal compliance — Economics at UNSW, Law at the University of Sydney, and a Master of Laws from UCL. Phuong anchors our work in the heart of the not-for-profit sector, with a degree in Social Work from UNSW and a lifelong commitment to inclusive, ethical design.

As a 100% Australian-owned business, we bring those worlds together: a done-for-you Donation Engine — and the smart website behind it — legally robust, deeply accessible, and built to help Australian charities rise, grow, and do more of what matters.

Australia has trusted us with giving before.

Our founders built and ran PeoplePledge — Australia’s first medical crowdfunding platform — processing over $1 million in donations for families facing a health crisis. That work earned the Pride of Australia Medal and a place on Anthill’s Top 30 Under 30. We know, first-hand, what makes people give.
