Client Overview

Tatcha UK is a boutique skincare brand specialising in natural serums and treatment kits. They had strong product-market fit but inconsistent sales cycles — driven mostly by unstable social media ads.

They needed a predictable engine, not a lucky campaign.

​

The Challenge

• Rising ad costs with declining ROAS

• No automated retargeting

• Low returning-customer rate

• Sales dependent on viral spikes

• No funnel structure or data insights

Tatcha UK wasn’t struggling with demand — it was struggling with system design.

​

 Sharpscale Engineered Strategy

We built a multi-layered growth architecture:

1. AI-powered audience segmentation

2. Dynamic product funnel (awareness → conversion → retention)

3. WhatsApp automation for instant follow-ups

4. Email + SMS cross-channel onboarding flows

5. Ad account restructure with data-led creatives

6. A/B testing and CRO across product pages

Every decision was insight-driven, not assumption-driven.

​
