01 · Challenge

Currency chaos — and a missing piece of the customer journey.

World First needed two things at once: a custom solution to give customers live, accurate currency conversion data, and a paid programme to bring high-intent users to their international money-transfer offer.

Without the tool, the brand was missing a critical trust moment in the buying journey. Without the paid programme, even the best tool would sit unused. The brief was build and launch in 90 days — and prove revenue inside the same window.

02 · Approach

Tech build and paid performance, executed in parallel.

We treated this as one programme, not two. The web app team and the paid-media team worked the same brief — every campaign landed on a page where the live currency tool earned the click's trust, and every tool feature was instrumented so we could see what was driving revenue.

Three workstreams ran in parallel, all anchored to a single metric: revenue from money-transfer customers acquired through paid social.

The 90-day playbook
3 workstreams · 1 metric

Real-time web app build

Our team built a custom web application displaying live global currency rates with zero lag — fully responsive, intuitive, and engineered as both a user tool and a lead magnet.

Paid social campaigns

Tightly segmented Meta Ads targeting users seeking fast, reliable money transfers — every ad tied to a conversion-focused landing page integrated with the live-rate tool.

UX and data integration

Web app fully wired into analytics and CRO tools to track engagement, conversions and revenue metrics in real time — closing the loop between feature usage and pipeline.

Continuous optimisation

Weekly testing on creative, audiences and landing pages — compounding the ROAS as the programme matured across the 90 days.

03 · The result

$31.2K in revenue, 6.3X ROAS, and a live tool that keeps earning.

Inside 90 days, World First's paid social programme delivered a 6.3X return on ad spend, generating $31.2K in revenue from a standing start. The disciplined launch turned every dollar of media into measurable money-transfer business.

The currency conversion web app drew consistent traffic in its own right, lifted time on site and positioned World First as a reliable transfer provider — a tool, an SEO asset and a conversion lever all in one build.
