We build the web, the integrations and the AI your brand runs on.
Websites and stores, connections between your systems, AI that works on your real data, and automations for marketing and Amazon. We build it, we hand it over, and your team runs it. 10+ years inside commerce operations.
What our clients say
Four areas, one team
Start with the one that matches what is costing you money today. They connect, but you can buy any of them on its own.
Web & ecommerce
The site and the store, and the plumbing between them and the rest of your systems.
Applied AI
AI connected to your own data and systems, not a chatbot bolted on top.
Marketing & Amazon
We build the automations and recover the money. We do not run your accounts.
Direction
For when the problem is not one project but nobody steering the AI.
Astro websites and migrations
A fast site your team can edit without breaking it, built on Astro: ready for search engines and for AI answers (SEO and GEO), with no plugin stack to patch. Coming from WordPress, Wix or another platform? We migrate your content and URLs, with redirects to protect your search visibility. You do not need AI for any of this; it is simply a better website. Web projects usually take 4–6 weeks.
For brands whose site is slow, fragile, or tied to a platform they have outgrown.
You walk away with
- The new site live, with every old URL redirected
- Content your team edits itself, with no developer needed
- Source code in your repository and a short handover session
Shopify stores
A store built or rebuilt on Shopify and connected to what sits behind it: catalogue, stock, ERP, marketplaces. We set it up around how your brand actually sells, and leave it in a state your team can run day to day.
For brands launching an online store, or leaving a platform that no longer fits.
See the full page →You walk away with
- A store live and tested with your real catalogue
- Connections to your stock, ERP or marketplace feeds where you need them
- Your team trained to manage products, content and orders
Custom integrations (ERP, Vendor Central…)
Your systems hold the data but do not talk to each other, so someone copies numbers from one to the next. We build the connections: ERP, CRM, marketplaces, Amazon Vendor Central and anything else with an API. Read-only first, so you see it working on real data before it can write anything.
For teams that spend part of every week moving data by hand.
You walk away with
- Connections that run unattended, with a log of what moved and when
- Writing to your systems switched on only when you decide
- Documentation and the source code, yours to keep
AI shopping assistant for online stores
A chat on your store that answers product questions from your own catalogue, tracks orders, handles returns and suggests the right upsell, in every language you sell in. When it should not answer, it hands the conversation to a person. If you also sell on Amazon, it can read that data too.
For stores whose support team answers the same questions all day.
See the full page →You walk away with
- Answers grounded in your catalogue, not in guesses
- Order tracking and returns handled inside the chat
- Handoff to your team, with the conversation attached
Marketing automations
We build the programmed pieces of your marketing: reports that write themselves, feed and catalogue updates, alerts when a number moves, rules that act on your data. We also advise on what is worth automating. We build it and you run it: we do not manage your campaigns.
For marketing teams buried in spreadsheets and repeat tasks.
You walk away with
- Automations running on your own accounts and data
- A short written note on what each one does and when it acts
- Your team able to change the rules without us
Vendor recovery (Amazon Vendor Central)
Amazon deducts shortages, chargebacks and other charges from vendor payments. Some of them are wrong. We audit your Vendor Central deductions and dispute the wrong ones. Our fee is tied to what is recovered.
For brands that sell to Amazon as a vendor and have deductions nobody has time to check.
See the full page →You walk away with
- An audit of your deductions, with the wrong ones flagged
- Disputes filed on your behalf
- A clear record of what was disputed and what came back
Four steps, and you can stop at the first
Diagnosis. A short call. We tell you what is worth doing, what is not, and whether we are the right people. Sometimes the answer is no.
Written scope. Deliverables enumerated, a closed timeline, and what we need from you. Before any invoice.
Build, with you watching. You see it working on your real data before it can change anything.
Handover. Source code and access in your name, documentation, and your team trained. It stays yours.
We build. We do not run your accounts.
Not an account-management agency
We do not manage your Amazon, Google or Meta accounts with a human team. That is Roicos, a sister agency in our group. If that is what you need, we will tell you on the first call.
Not hours and slides
No hour banks and no strategy decks. You buy a deliverable with a date on it.
Not a lock-in
Source code, accounts and access in your name. Nothing you cannot take with you.
What brands say about working with us
With a vast catalog and little time, we trusted Epinium to optimize our listings. This led to increased organic sales and improved advertising performance through AI, allowing us to focus on growing our business.
Alberto Feria
CEO, Alfa Holding
With Epinium, we are able to save a lot of time editing our clients' listings thanks to its bulk editor and Artificial Intelligence. We are able to take care of their strategies.
Miriam Larrosa
CEO, Roicos
Our expectations were certainly exceeded. Everything is just so well thought out, and snappy. Their support team is excellent too!
Neus Dominguez
Marketplace Manager, Labbox
We use Epinium every day to monitor the status of all our ASINs across all marketplaces and improve our SEO very productively. An indispensable tool that lets us manage a much larger catalog than we imagined. Worth every penny.
Oriol Penya
Organic Beauty Brands
It is impossible to calculate the hours Epinium has saved me managing customer catalogs. I've modified catalogs of up to 3,500 SKUs and run SEO audits comfortably from the same panel.
Jordi Ordóñez
Amazon Consultant
Epinium's ability to analyze and adjust ads in real-time based on performance has enabled us to maximize ROI and achieve our business goals more effectively. Without a doubt, I recommend Epinium to any seller.
Edgar Alvarez
Head eCommerce, BANDAI Entertainment Europe
The questions that come before the first call
What services does Epinium offer?
Four areas. Web and ecommerce: Astro websites, WordPress migrations, Shopify stores and custom integrations. Applied AI: custom development, MCP connectors and AI shopping assistants, all in the applied-AI hub. Marketing and Amazon: marketing automations, vendor recovery and demand forecast. And direction: AI Director, under our NerveOps™ method. You can buy any of them on its own.
Do I need AI to get a new website?
No. A new website or a migration is a web project, and AI is not part of it unless you want it to be. We build on Astro because it is fast, easy to edit and ready for search and for AI answers, not because it needs AI.
Is this an agency? Will you manage my accounts?
No. We build so that your team operates it. Managing ad and marketplace accounts with a human team is a different business, Roicos, and a different company in our group. Here the automations work on your accounts and the decisions stay with you.
How much does it cost?
The scope decides it, so we do not publish a rate card. We price the deliverable rather than the hour, and you get the number in writing before any invoice. The diagnosis is free and includes the part where we tell you something is not worth doing. For vendor recovery, our fee is tied to what is recovered.
What happens to my data?
It stays where it is. We deploy on your infrastructure, we do not proxy your data through us, and what we build runs with EU hosting and a log of what it did. Source code and access are in your name.
Do you work with my stack: Shopify, WooCommerce, my ERP?
Shopify and WooCommerce stores, WordPress and other CMSs, ERPs, CRMs and marketplaces: if it has an API, yes. If it does not, we tell you in the diagnosis instead of discovering it in week three.
How fast can we start?
The diagnosis takes one call. Once the scope is written and the access is ready, web projects usually take 4–6 weeks. Anything else depends on the scope, which is what the diagnosis is for.
Tell us what you need built
A free diagnosis: one call, and we tell you what is worth doing, in what order, and whether we are the right people. Sometimes the answer is no.
