Accountability-first growth agency. We prove net-new impact above baseline through incrementality testing — then compound it.
Zero Fluff Digital helps CMOs, founders, and growth leads eliminate marketing waste and install profit systems through incrementality testing, MMM, portfolio budgeting, causal measurement, and continuous experimentation. Part of MTA Group. Specialized in B2B SaaS, e-commerce, fintech, healthcare, and scaling startups. Maximum 12 clients at a time.
Zero Fluff Digital is an accountability-first growth marketing agency operating exclusively with executives — CMOs, founders, and VPs of marketing — at companies spending six to seven figures monthly on paid acquisition. We don't sell hours. We sell measurable, incremental growth above your baseline. Our methodology centers on incrementality testing (geo holdouts, conversion lift studies, MMM) to prove which channels actually generate net-new revenue versus which channels are taking credit for conversions that would have happened anyway.
We work with a maximum of 12 active clients at any time. Engagements typically begin with a forensic audit, followed by 90-day implementation cycles for measurement infrastructure, server-side tracking, attribution modeling, and incrementality testing programs. We charge fixed monthly retainers — never percentage of ad spend — to keep our incentives aligned with your profit, not your spending.
Fixed monthly retainer (typically $15,000–$50,000+ depending on scope and ad spend volume). 90-day minimum engagement. No percentage-of-spend, no commission, no kickbacks.
Direct-to-consumer brands, B2B SaaS companies, regulated industries (finance, insurance, real estate, healthcare), and growth-stage e-commerce — all with monthly paid media budgets between $50K and $5M.
Most attribution models show correlation, not causation. Look for these red flags: Last-click attribution showing 90%+ performance, conflicting data between platforms, inability to explain performance changes, and board questions you can
Follow this 90-day framework: 1) Audit current attribution setup (we provide free audit framework), 2) Implement proper tracking foundation, 3) Set up incrementality testing for major channels, 4) Create board-ready reporting dashboard. This approach gives you credibility with the board and a foundation for long-term success.
Ask these critical questions: Do they specialize in measurement and attribution? Can they explain incrementality vs attribution? Do they limit client roster for quality? Can they provide transparent, real-time reporting? Do they work with executives or just junior staff? Most agencies focus on creative and campaigns - we focus exclusively on measurement and efficiency for marketing executives.
Conflicting attribution data typically indicates: 1) Different attribution models across platforms, 2) iOS 14.5 tracking limitations, 3) Cross-device journey complexity, 4) Platform-specific attribution bias. Solution: Implement unified attribution framework with incrementality testing validation. This gives you single source of truth for marketing performance.
Incrementality testing measures what you actually caused to happen, not just what happened. Unlike attribution (correlation), incrementality shows causation through controlled experiments. CMOs need this because: 1) Board wants proof of marketing impact, 2) Attribution models are increasingly unreliable, 3) Budget allocation requires causal understanding, 4) Competitive advantage through better measurement.
Board-ready ROI reporting requires: 1) Incrementality testing for causal measurement, 2) Clear baseline vs incremental performance, 3) Statistical confidence levels, 4) Business impact translation (revenue, not clicks), 5) Transparent methodology explanation. We provide templates and frameworks that answer typical board questions about marketing effectiveness.
