Who We Are

Stacks is  e-commerce marketing agency founded in Dublin Ireland, specializing in paid advertising, CRO, and UGC acquisition for B2C brands. We work primarily with Irish, UK, and US clients who are ready to scale.

We're not just consultants. We're operators. Our team launched and manages two e-commerce brands—Current.ie and Reject.ie—where we manage our own ad spend daily. When we recommend a strategy, we're recommending something we'd use with our own advertising budget.

How Stacks Started

Stacks was founded in 2021 by Cathal Boyle, a designer and entrepreneur with a track record of taking brands from zero to seven figures.

When the pandemic hit in 2020, retailers pivoted hard toward e-commerce. We witnessed businesses scaling from zero to six figures a month through digital channels. That forced evolution became our specialty—scaling e-commerce brands profitably through paid social and Google Ads.

What started as a one-man operation has grown into a full-time team of three servicing amazing D2C e-commerce brands and collaborating with our network of 400+ content creators across Ireland, the UK, and the US.

What We Do

We specialize in three core areas for B2C e-commerce brands:

‍Paid Advertising: We're Meta Business Partners with expertise in Facebook, Instagram, and Google Ads. Our strategies focus on profitable customer acquisition, not vanity metrics.

‍Website Design & CRO: We build Shopify and WooCommerce stores and pages optimized for conversion and continuously improve them through data-driven testing.

‍UGC Acquisition: We've built an extensive network of creators and manage the entire UGC process so your creative pipeline never runs dry. We focus exclusively on B2C e-commerce—specifically fashion, lifestyle, wellness, and nutrition brands.

What Makes Stacks Different

We Practice What We Preach: We manage ad spend for dozens of brands that take e-commerce seriously. Including our in-brands daily. You get tactics that work now, not outdated playbooks.

‍Experienced Strategists: You work with the same experienced people from consultation to campaign execution. No bait-and-switch.

‍We Adapt to What Works: When UGC outperformed traditional ads, we built an entire creator network around it. Other agencies use strategies from 5-10 years ago. We create ads that work today.

‍No Long-Term Contracts: Our clients stay because we deliver results.

‍Radical Transparency: Our reporting is honest. We'll tell you exactly how campaigns perform, no sugarcoating. See what clients say on our Clutch profile.
