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.

Building Trust in Measurement

Rebag implemented DV Rockerbox™ as its centralized measurement platform over five years ago. When multi-touch attribution (MTA) was delivered, it provided rapid insights and clarity on how channels performed relative to one another.

“DV Rockerbox’s impact was immediate with the first model that you built.”
– Elizabeth Layne, CMO, Rebag

Over time, DV Rockerbox became embedded in how the team understood performance across digital channels. That consistency built trust in DV Rockerbox’s de-duplicated performance and MTA, which gave the team a dependable lens for evaluating channel efficiency.

Scaling TikTok With Deterministic View-Through Data

As TikTok grew into a larger opportunity, Rebag approached investment expansion carefully. Because the team had already built confidence in DV 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 DV Rockerbox. I think it gave us more confidence in scaling with TikTok.” – Elizabeth Layne

Through DV 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 DV Rockerbox to validate performance and guide budget decisions, enabling confident scaling.

Executive Discipline Through Centralized Reporting

While the DV Rockerbox platform drives tactical channel optimization, Rebag leverages DV Rockerbox’s warehousing integration as the foundation for executive reporting.

DV Rockerbox centralizes Rebag’s spend across channels and feeds that data into Rebag’s data warehouse before flowing into Looker. There, it layers in internal order data to calculate LTV to CAC, the company’s top-line acquisition efficiency metric.

“We calculate our own LTV to CAC using DV Rockerbox data and Shopify data, and we review that daily.” – Elizabeth Layne

This structure creates alignment across the organization. Marketing optimizes channel-level performance in DV 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.

A Trusted Partner in a Complex Attribution Landscape

In the early stages of adoption, the DV 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 DV 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

Today, DV 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.
