Front End Development Consultants in Barcelona

Feel at home

La Saleta is the place where family gathers, where everyone shares joys or sorrows, makes plans, and speaks openly about problems. It is the circle of trust with whom to share concerns, seeking the advice of those who care about you. At La Saleta, you always find support and, above all, solutions.

La Saleta is much more than a location; it is a feeling: the feeling of being with your own. That's who we are, one of your own: a close collaborator, someone who knows you, understands you, and is there when you need them.

Sit with us. Tell us how you are. Let's talk about your needs and problems. Let us help you. Let's find solutions!

OUR DNA

We are an independent communication agency. Three complementary profiles and an army of micro-specialized collaborators, working together for effective, transversal, and multidisciplinary communication. Few people, but a great team.

After more than twenty years of experience in the communication, advertising, and marketing sector, we decided to gather in the intimacy of La Saleta to do what we know how to do (and do it the way we like). We work side-by-side, with common sense, rigor, passion for the profession, and good humor. We put our knowledge, experience, and creativity at the service of ideas that "work," to offer effective communication solutions, adapted to the needs of each client.

We are not a big agency, but we are a great agency.

ADHOC SOLUTIONS

Chair, sofa, ottoman, armchair, stool... Each person prefers a type of seat; not all are equally comfortable, not all suit you. Every business is unique, and every brand is different.

Each client requires a different and personalized action plan; a unique combination of channels, messages, and actions adapted to their current situation, their needs, their resources, their audiences, their objectives...

We offer specific communication solutions, but we like to go a step further. We believe in integral, coherent, and transversal communication.

We work in the medium and long term, with 360-degree proposals that take our clients where they want to go.

🔹 Customized solutions: Every company is unique, which is why we create tailored strategies adapted to your sector and needs.

💡 Validated experience, real impact

We are not a conventional agency. At Atomic4, we've been on the other side: we don't just develop strategies for clients; we've launched and scaled our own businesses.

🚀 We have co-founded and led successful startups like Solfy, Tattoox, GoPop-Up, and Hausum, managing every phase of their digital growth.

🏆 We have also worked with large companies and industry leaders such as RACC, Lidl, Don Piso, and La Caixa, applying proven and optimized strategies for scaling.

💰 In many of these projects, we've invested our own money, so we know what works and what doesn't in a digital business.

This background allows us to offer something few agencies can: real business vision. We don't just design websites; we create digital platforms designed to attract, convert, and retain customers, ensuring your investment has a measurable and sustainable impact.

A little about ASPID.

Since 2004, we have been helping companies that sell to other companies to stand out and convince with their communication. We have the right mix of strategy, creativity, and design to build differentiating brands. And what does this mean beyond words? This isn't about numbers,

but let's start with figures_

We have specialized in B2B and industrial communication since 2004. We have worked for more than 40 different industry sectors. On more than 700 projects in 23 countries. Although what's important here is the story behind all of this. The experience gained, what we have learned about B2B communication and how to make it effective.

A constantly changing world forces B2B companies to evolve with it, to seek new perspectives and more digital viewpoints that make a difference. That's why we are consultants, communicators, marketers, creatives, and designers. That other perspective on B2B marketing that will help you achieve your short, medium, and long-term goals.

Understanding people

to understand B2B_

Throughout all this time, we at the agency have understood that the most important thing in business-to-business communication is people. Knowing the B2B environment means knowing the motivations of the people who are part of it. Because when you understand motivations, you understand mechanisms. That's why we believe that generating credibility is the foundation of everything.

If there's one thing we believe in,

it's creativity_

Believing is very similar to creating, and it's no coincidence. Although it's not a matter of faith. It's about trust. We trust creativity to express what differentiates your brand in a competitive world. To make it relevant. Because no, we are not all the same, especially not in communication. Creativity, combined with strategy, is fundamental to defining the 'what' and the 'how' to build your brand solidly, giving it a unique voice. For us, specialized communication in B2B and industry has nothing industrial about it.

We want to see

your brand grow_

Because that's how your sales grow.

This is no different from what others say. Only we won't talk about KPI, ROI, ETC until the end. We build solid brands that differentiate you, connect with your audience more intensely, and remain in the minds of your potential clients.

Here we will talk about how to build lasting relationships that improve your results, how to take your brand further with strategy, creativity, and design. We are going to bring out all the good within you.

SERVICES Branding/Brand We create relevant brands for your clients: differentiated and with a defined value proposition. We work on brands so they are more than just a name and so their audiences perceive an optimal image in terms of quality, credibility, and coherence. Marketing We help companies understand and analyze their situation in the different commercial areas of their business. We identify opportunities that generate more sales and sustainable growth. We implement B2B marketing strategies and take brands to a new level. Design and communication We make the complex simple through strategy, creativity, and design. We create platforms and design commercial tools, products, and campaigns focused on achieving set objectives. We increase the recognition of B2B brands. Digital We develop your brand's identity digitally, bringing all your B2B products and services closer to your technical buyer. Through website design and programming, we enhance your industrial company's brand image and services.
