90-Day Sprints: Guaranteeing 2x Revenue Growth for DTC Brands

In this episode of The Future of Consumer Marketing, host Andres Figueira interviews Hal Smith, Founder of H Street Digital, a performance marketing agency that guarantees to 2x digital advertising revenue for eight-figure DTC brands in 90 days. After a decade of scaling multiple performance marketing agencies and working across presidential campaigns, Fortune 100 banks, and DTC brands, Smith identified the systematic bottlenecks that prevent most brands from scaling efficiently. His agency's approach differs radically from the typical agency model: they audit brands across five core performance levers, identify the single biggest constraint using theory of constraints methodology, and commit to specific, measurable outcomes through 90-day sprints with full refund guarantees if they don't deliver. Topics Discussed: - Applying theory of constraints to identify the biggest growth bottleneck in DTC brands - Building a performance marketing audit framework across thousands of data points Using 90-day outcome-based sprints with measurable KPIs and refund guarantees - Leveraging AI for creative research and customer insight extraction Testing product-market fit through systematic persona and pain point matrices - The five core performance levers: offer strategy, creative systems, media buying, CRO, and attribution - Why tactical advice on social media often delivers low-impact results Building a lean, profitable agency model focused on accountability over growth - Preparing for agentic commerce and AI disruption in the DTC ecosystem
