You’ve moved buttons "above the fold" (classic AI bs). Tested "the sauce" from a CRO goat on Twitter (classic human bs). You have pretty decks with sexy graphs (classic A/B-testing tool bs). But you know the testing is safe, incremental, disconnected from your customers. And has no real business impact. We've been doing CRO since 2009. We're not still figuring it out. We've already paid for the mistakes you're about to make.

1️⃣ Humble Bunny — Flipping the “Japan Is Hard” Narrative Most international brands think: “Japan is complicated.” “Consumers are different.” “Performance is always lower.” They’re not wrong — Japanese CVR is often ~35% lower than global averages But that’s not a reality of a "sleeping" Japanese market: it's an endemic of underperforming and disconnected marketing strategies. At Humble Bunny, our mission is to elevate businesses out of the 96.9% that underperform in Japan and into the top 3.1% We’re here to prove one thing: When you apply the right structure, psychology, and localization toward conversion (not just translation), Japan becomes predictable, measurable, and scalable 2️⃣ Our Average Performance (Not Cherry-Picked Case Studies) We track averages because testimonials can be faked — real, quantified performance can’t Here’s what our Clients are achieving on average... - 5.7x average lead generation increase (across our service-based Clients) - 5.8x average sales increase (across our EC/product-based Clients) - 91% average CVR lift - 51.2% average reduction in customer acquisition costs - 95.5% contract renewal rate We publicly track our averages because Clients like you want to know if we're actually consistent. We think the answer is 'Yes'. Moreover, if we underperform your project, those averages will go down. That’s real skin in the game and real incentive for us and our staff to make sure we do well on you! 3️⃣ Our Frameworks are our Advantage We don’t “try tactics.” We build, rebuild, train, and retrain around systems 🔹 LocaRISE® & The 8 Lenses of Japanese consumer buying decision We built and quantified a proprietary formula for how Japanese consumers achieve confidence and then make the decision to buy. This is not just “pretty localization", this is conversion-focused localization. 🔹 TrueVP® and TrueCopy™️ - Structured Ad & Copy Frameworks 🔹 TrueTrack® - Data design and the 3/2/1 Analysis System 4️⃣ Free Offer — Let’s Pressure-Test Your System If you’re operating a website in Japan, send it to us and we'll provide a light audit against the Lenses of LocaRISE® to identify: 1. What messages are distinctly missing 3. Where Japan-specific psychology is missing 4. What to fix first for the biggest lift If Japan has felt “hard,” it’s usually just a structure problem. Let’s fix that.

DAS Audience Development

Verified

Audience Development & Customer Intelligence Agency for Retail & Ecommerce Companies generating $10M–$100M in revenue.

Most brands treat their entire audience the same. Batch-and-blast campaigns. Identical flows for a first-time buyer and a fifth-time buyer. Segmentation that is under-segmented. Paid media eroding margins. DAS exists to fix that. We're a customer intelligence agency for brands in the $15M–$100M range. Every engagement starts with your data—purchase frequency, RFM segmentation, cohort-level LTV, and contribution margin analysis. We identify which customers are compounding value and which segments are eroding it. From there, we build the retention and acquisition architecture: lifecycle flows calibrated to actual buying behavior, campaign strategies segmented by customer value, acquisition strategies that find more of your best customers, while doing so with increased efficiency, and deploy frameworks your team owns long after we're gone. Clients include Koia, Leesa, GT's Living Foods, Create Wellness, and Hydrant. Average engagement lasts 4+ years. We take on 10-15 retainer clients per year—a deliberate constraint that keeps our team of senior operators embedded in your business, not spread across thirty accounts. If your business metrics have plateaued despite good execution, the problem probably isn't creative. It's who you're sending to and the systems that enable the marketing and advertising functions.
