(0 review)We unleash business's ability to scale.
Digital Position is a full-stack performance marketing agency that exists to solve one core problem that we see with nearly every business we work with... That problem is Phantom Progress: when a brand has a marketing department, multiple contractors, or even multiple agencies spending time and money on marketing, but they aren't seeing an impact on growth or profitability. They're stagnant despite all the time and effort put in. This defines a big misunderstanding between activity and progress. Irrelevant messaging and fragmented marketing efforts that seem proactive, but actually just waste time, money and energy. Most agencies look at isolated tactics or operate in siloed channels (Google, Meta, SEO, organic social, CRO, etc.), but we take a holistic view, looking at the whole ecosystem and how every piece works together to drive progress. We align strategy and execution to work towards the same objective: reaching the right audience faster, reducing wasted spend, and turning marketing into a predictable money-printing system. A few wins we’re proud of: Fleet Feet: +429% SEO revenue and 400,000+ tracked store visits, plus top 5 rankings for “best running shoes” and major brand terms Minnow Swim: Drove 100 new customers daily, +46% sales YoY, inventory sold out! Crossrope: +72% in new customer revenue, +38% increase in total revenue on a flat ROAS Straight from client slack chats: “You have shown and demonstrated you know more about us and Amazon than any consultants we have worked with in the past.” “It’s never ‘no.’ You guys are always ‘yes, and…’ moving the conversation forward.” "We actually hit an all time PB for revenue, orders placed, profit, and gross margin. Huge wins!" So, if... You’re chasing tactic after tactic but not scaling You’re hitting a wall with content creation & execution You want a partner who cares about the outcome as much as you do ...then let's connect. Stop guessing, start growing.6 works in EcommerceLocated in United States, United States (+1)From €3,000 for EcommerceWorked in Clothing & Accessories (+2)Speaks English11-50 membersconnecticut shotgun

(0 review)Automate. Build. Scale. AI-native digital products for ambitious businesses.
Design World Studio is a hybrid AI and software development studio built for businesses that want more than a website - they want an intelligent digital product that works as hard as they do. We work across three main areas: web and software development, mobile app development, and AI and automation. On the web and software side, we build high-converting websites, custom web applications, SaaS dashboards, and full-stack software engineered to scale. Our mobile team ships native iOS and Android apps, as well as cross-platform builds from a single codebase. What sets us apart is our AI practice. We don't treat artificial intelligence as an add-on; it's core to how we build. We develop production-grade AI agents that plan, decide, and execute multi-step tasks, chatbots trained on a client's own product, tone, and data, and workflow automation that eliminates manual busywork and self-corrects as it runs. We have particular depth in real estate technology, having built custom CRM tools, listing platforms, and portfolio management systems for brokerages and property teams. We also build learning management systems, MVPs for early-stage founders, and full-scale platforms for companies ready to invest in long-term digital infrastructure. Every engagement starts with understanding the actual business problem, not just the feature request. We scope a realistic timeline and build a solution meant to grow with the client, not be replaced in two years. Most of our client relationships continue well past launch, with ongoing support, monitoring, and iteration as the product and its user base grow.Looking for work in EcommerceLocated in Darien, United StatesFrom €3,000 for EcommerceWorks in multiple industriesSpeaks English11-50 membersdesverto
