About Wieldex
Who We Are
Vivian Mitsiou, the founder of Wieldex, has worked as a marketing consultant since 2015. Over those years, a pattern kept repeating: strong brands, strong products, mediocre results. In 2021, drawing on real case studies and real customers, she set out to understand why.
The answer wasn't in the product, the brand, or the colors. It was in trust, experience, and loyalty. Brands were investing in campaigns and redesigns without a system for how any of it connected to whether a customer trusted them enough to return. That insight became Wieldex, launched in January 2022. By 2023, Vivian had organized what she'd learned into a formal methodology: Ecommerce Experience Design.
We exist to bring that methodology to small and medium-sized businesses — connecting every piece of work to the trust and loyalty it's meant to build, shaped around what your brand needs rather than around a fixed package.
We believe in helping brands that already have real ambition and vision but haven't yet found the way to communicate what makes them different. We work alongside businesses that expect quality, results, and performance that lasts — and alongside partners who want to take better care of their own customers without compromising on quality.

What We Do
- We build the trust, retention, and loyalty that turn a first purchase into a lasting relationship.
- We automate and systemize what already works, so your growth doesn't depend on doing more of it by hand.
- We research and document how your specific customers behave — insight that strengthens your whole marketing strategy, not only your store.
- We grow your organic reach through SEO, GEO, and CRO, guided by evidence rather than guesswork.
- We create commercial photography that shows your real competitive advantage, built to connect with customers from the first moment.
Ecommerce Experience Design is the framework behind everything we do: we design, build, and optimize the experience your store gives its customers, combined into one connected system rather than left to separate vendors who rarely talk to each other.
We don't offer social media or media buying — that isn't where our expertise is. What we focus on is the part of your business your customers actually experience: the store itself, and the trust it earns.
We are not purely an agency, and we are not purely a consulting firm — we are both. We build the strategy and implement it ourselves until it's proven to work at scale for your business. Once it does, we automate what can be automated and document the rest, so the system doesn't depend on us to keep running. Our goal isn't only to deliver results — it's to transfer the knowledge behind them.

We want forward-thinking brands to care as much about the experience they give customers as they do about the traffic they bring in. Decisions are made online now, and that reality isn't changing — so an experience that is only functional is no longer enough; it has to earn trust.
This applies to brands of every size, not only the ones that already look big. We believe every brand willing to prove its worth deserves the chance to grow into something ethical, sustainable, and genuinely trusted in its industry.

Our Mission
Our mission is to bring Ecommerce Experience Design to small and medium-sized ecommerce brands.
Our data-driven approach combines customer behavior, design, and technology into one connected system, rather than treating them as separate initiatives.
Drawing on behavioral research and real data, we help you see clearly what's working and what isn't, so growth compounds into lasting trust, loyalty, and lifetime value.
Guidance, not sales.
The standard we hold ourselves to — and the one we believe your customers deserve too.
Our Philosophy
Our philosophy starts with what we believe makes a better experience: guidance, not sales. We hold ourselves to that standard in how we work with you — straightforward answers rather than embellished pitches, realistic projections rather than guarantees.
We believe this same standard belongs with your own customers. A store that only tries to convince someone to buy is optimizing for a single transaction. A store that guides someone toward the right decision, and builds the trust and experience worth returning to, is optimizing for loyalty. That's the difference we design for.
Simply put: the point of Wieldex is to build the kind of trust and loyalty that keeps customers coming back long after the first purchase.
Questions We Hear Most
Do you offer social media and advertising services?
No. Wieldex specializes in organic growth, strategy, and systems. However, we collaborate closely with our clients' agencies and internal teams to ensure a cohesive omnichannel experience.
How long should I wait to see marketing results?
Marketing timelines depend on multiple factors. Clients who already run ads, have an active social media presence, and operate a technically optimized ecommerce store can achieve faster results through CRO. In these cases, it is reasonable to expect measurable results within one to three months.
What is your minimum starting price?
€1,500 is the starting investment for a one-month Pilot Consulting engagement. Pilot Consulting serves as an entry point for new clients to identify, in practice, which services best fit their needs, and to ensure Wieldex is the right fit for each other.
Who will I actually be working with day-to-day?
Wieldex is led directly by Vivian Mitsiou and supported by senior experts who collaborate on a per-project basis. We intentionally take on a limited number of clients each cycle and train client teams to continue the work independently. In most cases, Vivian Mitsiou is directly responsible for the project.
What is Ecommerce Experience Design?
Ecommerce Experience Design is Wieldex's structured, end-to-end system that aligns positioning, design, marketing, and retention into one integrated growth engine, rather than treating each as a separate tactic.
Where is Wieldex based?
Wieldex is based in Athens, Greece, and works with ecommerce brands worldwide.
