The work

Case studies, by method.

Three illustrative scenarios — one each for paid ads, organic content and email — showing how GrowMint's methodology turns testing into profitable growth, and the metrics we optimise at each stage.

Methodology illustrations. These scenarios demonstrate GrowMint's process and the metrics we optimise. They're representative of our approach — we swap in named client results as the roster fills.

Challenge

A Melbourne skincare brand was burning $6k/mo at 1.1x ROAS — the same two creatives for four months, frequency climbing and CPA doubled from $18 to $41.

Approach

12 new UGC-style videos across three hook formats → rebuilt cold / warm / hot campaign architecture → PAS copy rewrite → a dedicated product landing page (CVR 1.4% → 3.2%).

Challenge

A UK supplement startup had a great product but 340 Instagram followers, no TikTok and no ad budget — selling almost entirely to friends and family.

Approach

Built a founder-led "content character" → 16 scripted, authentic short-form videos a month across TikTok, Reels and Shorts → a DM funnel from viral content to product.

Challenge

A US pet brand had a 28,000-person email list built over three years sitting dead — one monthly newsletter, 11% open rate, 0.4% clicks, no automation at all.

Approach

Built 6 automated flows — welcome, abandoned cart, post-purchase and more — plus a weekly broadcast cadence. Repeat purchase rate rose from 14% to 31%.
