Door One · The growth engine

A serious growth team, accountable to your numbers.

This is the standard way to work with us: Elephant Room as your performance agency. Always open, no equity, no strings. Here's exactly what that is, who runs it, and what it costs.

Who you'd be working with

Founded in 2014. A performance agency that only does eCommerce.

We've helped over 110 Australian businesses change how they do business online. The offering is built on three primary domains, Acquisition, Retention and Measurement, run by dedicated specialists and our own operating system.

We are the first and only agency in APAC awarded the highest-level partner certifications across Shopify, Google, Meta and Klaviyo, and we run every account on Jumbo, our own AI-powered operating system. Most of the spend we manage is focused on growth in international markets, which is exactly where Sacred Legacy is heading.

The three domains

Acquire, retain, measure.

Acquire

New customers, profitably

Northstar: nCAC efficiency

Acquiring new customers through paid performance channels, search, display and social.

  • Media buying + planning across Meta, Google, TikTok
  • Ongoing budget, creative and optimisation
  • Experimental testing framework
  • Scaling to the threshold of diminishing returns
Retain

Lifetime value, not one-time

Northstar: CLTV lift

Post-purchase strategies that maximise lifetime value and loyalty for your existing customers, a major lever for a brand with a collector base like yours.

  • Customer lifecycle development (email, SMS, push)
  • Automated 24/7 conditional communication
  • Loyalty and personalisation, true 1:1
  • Repeat purchase that pays back acquisition cost
Measure

Clear measurement, not guesswork

Northstar: media efficiency

The numbers across media, customers and merchandise, all in one place, so you know what's working and what isn't.

  • Data extraction + unification (one model)
  • Dashboards across media, customers, orders
  • Incrementality measurement
  • Data activation back into your channels
What it costs

The real calculator we quote from

Not a flat percentage of spend. When you engage paid media it includes Core Performance Management and the Data Reporting suite as standard, then a tiered fee on the spend itself, plus only the retention and data modules you actually use. Move the inputs to see the live monthly number.

Acquisition · paid media
Retention · CRM / Klaviyo
$0 per month, ex GST

Tiered media fee on spend: 10% to $20k, 8% to $50k, 6% to $100k, 4% to $500k, 3% above. Core Management is $2,000, or $3,500 once spend passes $100k. One-time setup and discovery is $2,000. This is the live engine; the exact scope is confirmed in a conversation.

Who runs it

The full-stack bench

You don't get one generalist. You get a dedicated team, each a specialist in their lane, coordinated by a single performance manager.

Performance Manager your primary contact, owns the outcome
Digital Strategist the quarterly roadmap and the lateral thinking
Paid Media Managers search and social, hands on the accounts
Data Analyst + Engineer the measurement and the data model
