What we do

One team for the full growth engine.

Most agencies own a single channel and point fingers at the rest. We run acquisition, retention, and conversion together — because that's the only way the numbers actually compound.

01

Paid Media

Meta, TikTok & Google campaigns built around contribution margin — not vanity ROAS. Daily management, ruthless testing, scale that holds.

  • Meta Ads
  • TikTok
  • Google & PMax
  • Media buying
02

Email & CRM

Klaviyo flows and campaigns that turn first orders into repeat customers. Welcome, abandonment, win-back and beyond — fully on-brand.

  • Klaviyo
  • Lifecycle flows
  • Segmentation
  • Campaigns
03

Shopify & CRO

Custom Shopify builds and conversion-rate optimisation that lift store-wide AOV and turn more traffic into checkout — tested, not guessed.

  • Theme builds
  • CRO
  • Landing pages
  • A/B testing
04

Creative & Strategy

Scroll-stopping ad creative and a quarterly growth roadmap. We brief, produce and iterate on the angles that move the metrics.

  • UGC briefs
  • Static & video
  • Offer strategy
  • Reporting
How we work

A clear path from audit to scale.

No twelve-month lock-ins or mystery dashboards. Just a tight, transparent process that gets to profit quickly and keeps it there.

01

Audit

We pull apart your account, store and data to find exactly where revenue is leaking and where it's hiding.

02

Strategy

A prioritised 90-day plan across media, email and CRO — mapped to the levers that matter most for your margin.

03

Execute

We build, launch and manage everything in-house, testing relentlessly and reporting in plain numbers.

04

Scale

Once it's profitable, we pour fuel on it — expanding channels, offers and markets without breaking the economics.

Selected work

Numbers, not adjectives.

"The first agency that actually understood our margins. Within a quarter we were spending more and keeping more. Genuinely a part of the team now."

Sofia LundFounder, NORDIQ

"Reporting is refreshingly honest and the creative output is on another level. Our email channel went from an afterthought to a third of revenue."

Marco KellerCEO, Atelier Sept

"We'd been burned by two agencies before GP & Co. The difference is they treat the P&L like it's their own. Couldn't recommend them more."
