Rebag is a leading luxury resale marketplace enabling consumers to buy and sell pre-owned designer handbags, fine jewelry and watches. As a highly performance-driven organization, Rebag monitors customer acquisition efficiency daily and dynamically adjusts spend across a diversified digital channel mix.
When TikTok began emerging as a meaningful acquisition opportunity, the team needed confidence that scaled investment would drive real business impact, not just platform-reported returns.
Rebag implemented Rockerbox as its centralized measurement platform over 5 years ago. When MTA was delivered it provided rapid insights and clarity into how channels were performing relative to one another.
“Rockerbox’s impact was immediate with t the first model that you built.”
— Elizabeth Layne, CMO, Rebag
Over time, Rockerbox became embedded in how the team understood performance across digital channels. That consistency built trust in Rockerbox’s de-duplicated performance and MTA, which gave the team a dependable lens for evaluating channel efficiency.
As TikTok grew into a larger opportunity, Rebag approached investment expansion carefully. Because the team had already built confidence in Rockerbox’s measurement framework, they were comfortable leaning into TikTok once deterministic view-through data became available.
“We first saw the success in measuring Meta with Rockerbox. I think it gave us more confidence in scaling with TikTok.”
— Elizabeth Layne, CMO, Rebag
Through Rockerbox’s direct integration with TikTok, Rebag gained deterministic visibility into performance beyond click-only reporting. With trusted cross-channel measurement in place, the team scaled TikTok spend over 100% year-over-year, bringing it to parity with Meta in overall investment.
Rather than scaling based solely on in-platform metrics, the team used Rockerbox to validate performance and guide budget decisions, which resulted in the ability to scale this channel with confidence.
While the Rockerbox platform drives tactical channel optimization, Rebag leverages Rockerbox’s warehousing integration as the foundation for executive reporting.
Rockerbox centralizes Rebag’s spend across channels and feeds that data into Rebag’s data warehouse before flowing into Looker. There, it is layered with internal order data to calculate LTV to CAC, the company’s top-line acquisition efficiency metric.
“We calculate our own LTV to CAC using Rockerbox data and Shopify data, and we review that daily.”
— Elizabeth Layne, CMO, Rebag
This structure creates alignment across the organization. Marketing optimizes channel-level performance within Rockerbox, while leadership monitors overall acquisition health through LTV to CAC reporting.
The result is disciplined scaling: confident channel expansion supported by executive-level efficiency oversight.
In the early stages of adoption, the Rockerbox team played a consultative role: answering modeling questions, supporting internal discussions, and helping educate stakeholders. This layer of support and partnership helped accelerate internal trust and embed Rockerbox into how the organization operates.
“Consultative guidance on channel decisions has been helpful, especially in the earlier days as we were launching new advertising channels.”
— Elizabeth Layne, CMO, Rebag
Today, Rockerbox serves as both Rebag’s optimization engine and its measurement foundation, guiding daily channel decisions while supporting executive-level visibility into acquisition performance. What began as a tool for attribution has become a core part of how the team evaluates growth, scales investment, and maintains discipline across the business.
