Why do so many brands trust our agency?
Talking to other agencies? Oh… we’re sorry.
3 real reasons why we’re different from the rest.
How can we help you?Always one step ahead
1. We set the trend and innovate
We do not do the same old marketing. We are pioneers at optimizing on platforms others do not even know are possible: we get ChatGPT to recommend our clients’ websites, we work SEO on YouTube and we automate processes with n8n that save thousands of hours a year.
We live marketing… and we teach it
2. References in Marketing, AI and UX
We do not just apply what we know: we teach it, prove it and share it. We are educators with over 500,000 followers, Pedro and Oscar teach at universities such as UPC, EAE Business School and UPV, and we run our own academy with 2,000+ members.
Partners of the leading software
3. We work with the most TOP brands
We are official partners of the most recognized software in the industry, such as TikTok, Elementor, Semrush and Raiola Networks. That means priority access, direct support and certified best practices: faster implementations, stronger integrations and more reliable results.

What our clients say
I reached out to Pedro and his team at Palo Seco 3 years ago to help me with the web positioning of my architecture firm. What I liked most was how transparent they were with us from the start, sharing all their processes and making hard-to-grasp topics easy to understand. Highly recommended.
Javier Ruyra VilluendasCEO of CeditechIf you want a team that does SEO not just to grow traffic, but to make a real impact on your business, the Palo Seco team is exactly what you’re looking for! On top of that, their training sessions are top-notch for anyone just getting started in digital marketing.
Borja Prieto BustamanteHead of Marketing at FactorialOscar from PALO SECO developed the Tok&Go branding for us with excellent results. Thanks to him we have a clear brand that conveys our values. Likewise, the working methodology for building the website made the whole process simple and the result outstanding.

Marco CreativoFounder of Marco CreativoNo ceiling
Whatever you imagine, we build it.
When a template can’t reach it, custom development has no limit.
Templates are fine until your idea outgrows them. From there on, every limitation costs you money and opportunities. Custom development removes that ceiling.
We start from your business goals and build exactly the product that meets them, without adapting you to what a tool allows.
Engineering + AI
Modern software, with intelligence inside.
We integrate AI as one more feature of the product.
AI is no longer a separate experiment: it’s a layer that can live inside your software, automating processes and improving the experience.
We use cutting-edge tools like Claude Code to develop with more quality and speed, reducing maintenance time and costs.
Built to grow
A foundation that doesn’t break when you scale.
Solid architecture from the first commit.
Many projects die of success: they grow and their technical foundation can’t keep up. We design with scaling in mind from the start.
The result is a product that supports growth without having to rewrite it every time you level up.
Benefits of custom development
Three reasons why, past a certain point, custom pays off more.
- 01
No limitations
Your product does exactly what you need, not what a template allows. Every feature is built for your specific use case.
- 02
Genuinely scalable
A solid architecture handles growth without collapsing. You invest once in a foundation that holds up when the business takes off.
- 03
Competitive advantage
Custom software is a proprietary, differentiating asset. Your competition can’t buy the same thing in a template marketplace.

Talk about the project
No fluff, no strings
Tried it before and it didn’t work? This is how we work.
- 01
We work with measurable goals (KPIs).
We do not hide behind 50-page reports full of vanity metrics. We set real indicators from day one: more sales, more bookings and more qualified leads. If it does not impact your bottom line, it is not real marketing.
- 02
Continuous contact: we are here for whatever you need.
Forget endless support tickets or talking to a sales rep who has no idea what happens on your site. You get fluid, constant communication with the specialists who execute your strategy, working as an extension of your own team.
- 03
No lock-in: no fine print.
We do not believe in fine print or holding clients hostage with 12-month contracts. Our best guarantee is work done well. If you stay with us, it is because you see your business grow month after month. Total freedom, absolute transparency.
FAQ
Have a question about custom development?
We’re here to answer them. And if any remain, let’s talk.
Talk to an expertWhen is custom development worth it over WordPress or No-Code?
When your project goes beyond what a template or a CMS can offer: complex business logic, deep integrations, large volumes of data, a real app, or demanding performance and security requirements. For a corporate website, WordPress or No-Code are usually enough; for a product or platform, custom development removes the ceiling and ends up being more cost-effective. We advise you honestly on which one fits your case.
Which technologies do you work with?
We mainly work with modern JavaScript/TypeScript stacks (React, Next.js, Node.js) and the databases and cloud services that best fit the project. We choose the technology based on your goals, budget and scaling needs, not on hype. We also integrate AI when it adds real value to the product.
How much does a custom project cost and how long does it take?
It depends on the scope, but we work in phases to control risk. We often start with an MVP (minimum viable product) that validates the idea with the right investment, and scale from there. Before developing, we define the scope with you and give you a realistic estimate of timing and cost. No surprises halfway through.
Can you integrate the development with my current systems?
Yes. A big part of the value lies precisely in integrations: we connect your new product with your CRM, ERP, payment gateways or any service with an API. We also develop our own APIs so other systems can integrate with you. The goal is for your entire ecosystem to talk to each other.
Is the code mine?
Yes, the code and the product are yours. We work transparently and hand you everything, with documentation so another team could continue it if you ever need to. We don’t believe in tying clients down technically: we’d rather they stay for the results.
