Websites and software that work for companies ready to grow
We have spent 2+ years building websites and platforms for companies in Spain. We do not sell templates or closed packages: every project starts with a conversation about what you actually need.

What we do for companies in Madrid
We're not an agency that does everything. We focus on three areas: web development, SaaS platforms, and AI integration. If your project fits, we'll say so. If it doesn't, we'll say that too.
Web development
Websites that load fast and show up on Google
Your website is the first thing a client sees before they talk to you. If it loads slowly or never shows up in search, it doesn't matter how good you are — you've already lost that chance. That's why every site we build is designed to perform and rank from day one.
We build with Next.js and React because they let us ship websites that are fast in the real world, not just in a PageSpeed report. We handle technical SEO (tags, structure, structured data) and true mobile-first design, because most of your visitors arrive on a phone whether you like it or not.
Includes
- Built with Next.js and React
- Truly responsive design
- Technical SEO and Core Web Vitals
- Custom design, no templates
- Hosting and domain setup
- Training so you can update content
SaaS development
SaaS platforms that hold up as you grow
A solid SaaS isn't just a website with a login. It's a product that has to handle subscriptions, payments, user data, and traffic spikes without falling over. If the foundation is weak, you'll rebuild everything once the first 100 paying users show up.
We've seen platforms that started well and broke once they grew, because someone picked the quick fix over the right one. We prioritize clean structure from day one, even if it feels slower at the start. You'll thank yourself later.
Includes
- Admin panels and dashboards
- Subscriptions and billing (Stripe)
- APIs and integrations
- Databases designed to scale
- Secure auth (OAuth, 2FA)
- Technical project documentation
AI for business
AI applied to real processes in your company
AI isn't magic, even when it's sold that way. What it does well is cut repetitive work: answering common questions, processing documents, connecting tools that don't talk to each other. If you're doing the same process by hand every week, it can probably be automated.
We don't bolt on AI for the trend. If a spreadsheet and two formulas solve it, we'll say so. But if a process genuinely benefits from automation, we build it and connect it to the systems you already use.
Includes
- AI chatbots and assistants
- Automation of manual processes
- Integrations between your tools
- OpenAI, Anthropic, and other APIs
- Free initial audit

About
Who we are at ADW Zenith
We are a small team in Madrid. We have spent 2+ years building websites and software for companies in Spain. We are not a large agency with sales teams and departments: the person who talks to you is the person who writes the code.
We don't sell smoke. We'd rather show you code and finished projects than a PowerPoint. This is what defines us:
TypeScript · Custom code · No templates
Custom code, not templates
We write TypeScript with a clear structure.
When something breaks or you need a new feature, knowing how the code is built is the difference between a 10-minute fix and a week-long nightmare.
