Turning Measurement Clarity into Scalable Growth
How Mac Duggal grew revenue with C+DV on TikTok and MNTN CTV

TL;DR

  • Revenue grew 27% YoY on 20% higher media spend, improving efficiency at scale
  • ROAS increased 5% as upper-funnel investment became measurable and fundable
  • TikTok scaled 143% YoY with efficiency maintained after C+DV activation
  • Unified cross-channel attribution aligned marketing and finance on one source of truth

Executive Summary

Prospect Knight and Mac Duggal partnered with Northbeam to replace bottom-funnel-biased reporting with a clearer, cross-channel measurement framework. As DTC scaled, Northbeam enabled Prospect Knight to confidently fund upper-funnel and video channels by connecting impressions to outcomes across devices and platforms.

Challenge

Mac Duggal is one of the most recognized names in women’s luxury apparel and evening wear, founded in 1984 and launched DTC in 2020 with Prospect Knight as the operating partner.

As DTC scaled, measurement lagged behind growth. Relying on GA4/UA skewed attribution toward bottom‑funnel channels while under‑reporting growth drivers like paid social, making it harder to fund new customer acquisition with conviction.

As the brand’s direct-to-consumer channel matured, Prospect Knight needed a measurement foundation that reflected how customers actually discover and decide—so they could scale upper‑funnel with confidence, not guesswork.

“GA4 heavily skewed and over‑attributed to bottom‑of‑the‑funnel channels, and really underreported some of the key growth drivers—Meta, TikTok, Pinterest.” — Conor Maurice, ProspectKnight

The team needed a single, cross‑channel view that was credible to both marketers and finance, so upper‑funnel could be evaluated alongside conversion‑driven activity in one framework.

Solution

Prospect Knight chose Northbeam for its tracking approach and alignment with Shopify order data (improving new vs. returning clarity), combined with a methodology and collaboration model that fit how Mac Duggal operates.

Northbeam’s Media Strategy sessions (alongside MMM) provided complementary reads to MTA—from daily signal to budget guardrails—so decisions weren’t anchored to one lens.

Prospect Knight implemented Northbeam MTA as the operating source of truth, layered MMM+ to triangulate budget decisions, and adopted C+DV to deterministically connect impressions to outcomes across devices and channels—especially in environments where clicks are rare (CTV).

What changed:

  • Centralized, multi‑touch view of performance replaced siloed platform reads and manual reconciliation.
  • Deterministic view‑through (C+DV) removed the “video black box,” so TikTok and CTV could be evaluated and funded with proof rather than hope.
  • Operating cadence: Media Strategy collaboration, creative/placement testing, budget re‑allocation, and MMM readouts for confidence at scale.

“Without using CDV we wouldn’t have been able to get the CTV channel off the ground… it’s been a game changer.”

Results

With Northbeam in place, Mac Duggal saw measurable gains in revenue efficiency and media effectiveness, supported by clearer attribution, faster insights, and stronger alignment between marketing and finance.

Quantitative

  • +20% media spend delivered +27% revenue growth YoY; ROAS improved +5%—efficiency rose at higher spend levels.
  • TikTok scaled 143% YoY with efficiency maintained post‑C+DV activation.

Qualitative

  • Measurement clarity became a competitive advantage. Video and social earned budget with evidence, accelerating growth without eroding efficiency.
  • Alignment across brand and performance. One measurement model improved finance–marketing collaboration and sped decision‑making.
