Who we are

Strategic Performance Optimization at a Global Scale

Hastamara Duntuntu is a performance-driven powerhouse dedicated to scaling e-commerce brands through mathematical precision. We move beyond basic ROAS, focusing on Marketing Efficiency Ratio (MER) and Profit-First strategies to ensure your growth is both aggressive and sustainable. By bridging the gap between creative intelligence and spend optimization, we turn complex data into global market dominance.

Driven by innovation, we are currently engineering an AI-Powered Creative Predictor. This upcoming tool will autonomously analyze creative fatigue and LTV data, allowing brands to predict campaign performance before the first dollar is spent. We don’t just react to the market; we use proprietary technology to stay ahead of it.

Common Questions

Most Popular Questions

Find answers to the most frequently asked questions about our E-commerce scaling & spend optimization services and solutions.

While ROAS only tracks direct attribution, Marketing Efficiency Ratio (MER) measures your total revenue against total ad spend. This gives us a "birds-eye view" of your brand's overall health and real profitability across all channels.

We use data-driven monitoring to track frequency, CTR trends, and CPA spikes. Our system alerts us the moment an audience stops responding to a creative, allowing us to refresh assets before your performance dips.

Most agencies bid for volume; we bid for margin. We align our bidding tactics with your COGS (Cost of Goods Sold) and net profit goals to ensure that scaling doesn't come at the expense of your bottom line.

Instead of just hunting for one-time buyers, we analyze your data to find "High-Value" segments. By targeting audiences similar to your most loyal customers, we increase your Customer Lifetime Value (LTV) and lower long-term acquisition costs.

Yes. We specialize in cross-border scaling, helping you navigate new market dynamics, localized ad creative strategies, and spend optimization for global territories.

Our AI-Powered Creative Predictor is currently in the late development stage. Clients on our Global Pro and Enterprise plans will receive priority beta access to use these predictive insights before the general public.

Our strategies are most effective for brands spending at least $5,000 - $10,000 per month, as this provides enough data to effectively utilize our MER tracking and AI optimization tools.

While initial technical optimizations (like MER setup and bidding adjustments) happen in the first 14 days, sustainable scaling typically takes 30 to 60 days to fully stabilize as we collect data on creative performance and audience behavior.
