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.

A full-service digital agency that combines ecommerce solutions, unique software partnerships and digital marketing to transform your business.

Resonate Online

Web and digital strategy for teams navigating growth and AI

Resonate Online is a strategic web and digital advisory firm helping marketing teams navigate growth and AI with clarity and confidence. We work with growth focused organizations that are evolving their positioning, modernizing their websites, and adapting to AI driven discovery. Our role is not to add more noise or more tools. It is to bring structure, focus, and measurable direction to your digital strategy. Our work typically moves through four connected areas: 1. Strategic Positioning and Digital Direction Clarifying your value proposition, competitive differentiation, and market narrative so your website and marketing efforts are anchored in strategic focus. This includes messaging frameworks, competitive analysis, and digital roadmapping to ensure every initiative supports growth. 2. Web Strategy, Design Leadership and Experience Optimization Leading website strategy and managing redesign or evolution initiatives from concept through launch. Acting as the strategic lead across design and development to ensure architecture, messaging, UX, and conversion pathways are aligned to business goals. The result is a website that performs structurally, strategically, and measurably, not just visually. 3. Growth, Search and AI Discovery Strategy Designing digital growth systems that support both traditional search visibility and AI driven discovery. This includes SEO prioritization, content structuring, funnel mapping, and ensuring your content is clear, extractable, and aligned to how modern systems evaluate and reuse information. 4. Measurement, Insight and Iteration Defining the right KPIs, building practical reporting frameworks, and helping leadership understand what is working and why. Turning analytics from overwhelming dashboards into actionable insights that guide prioritization, experimentation, and continuous improvement. What sets Resonate Online apart is a strategy first mindset. We do not lead with platforms or checklists. We lead with clarity. We view your website as an intelligence layer that is constantly evaluated by buyers, competitors, search engines, and AI systems. That perspective allows us to design digital ecosystems that are structurally sound, strategically aligned, and built for durable growth. Resonate Online delivers senior level thinking without agency bloat, offering direct partnership, clear recommendations, and focused leadership for teams navigating growth and AI.

A small group of your customers is driving most of your value. You're probably treating them like everyone else. DAS is a customer intelligence agency. We work with DTC brands that have built real revenue — $35M to $100M — but are watching margins compress and acquisition/retention performance plateau. The issue is almost never the creative or the campaigns. It's that no one has done the foundational work of understanding who your best customers actually are. We start with your data, not your campaigns. Our process maps your customer file through RFM segmentation and cohort analysis, identifies where margin is leaking, and builds the targeting and retention infrastructure that makes every downstream investment more efficient. We take on 12-15 brands per year. Typical engagements run 4+ years. Clients include Koia, Leesa, Chomps, AMIRI, and GT's Living Foods. If you've worked with skilled execution agencies and still aren't seeing compounding results, that's the gap we close.

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.
