The Salt & Silicon System

Client work. Product lab. Public thinking.

A frontier studio for the age of simulation.

Generative AI has made
almost anything possible.

That does not make every possibility worth pursuing.

The hard part is deciding what deserves to exist, what deserves to be said, and what kind of company you become in the process.

We stay small on purpose. You work directly with the people thinking through the problem. AI-native infrastructure gives the studio the reach of a much larger team.

For clients

We help companies and organisations turn direction into execution: audits, positioning, design, content, growth systems and custom AI products.

Product studio

We build our own products too: tools, audits and cultural experiments.

Thinking

We think in public about what remains human when machines can produce almost anything.

Salt Taste, story, direction
Silicon Systems, agents, speed

Together they turn possibility into meaning.

Strategy and design studio in Barcelona. Brand, systems, and growth. Same room, same conversation.

01 Why

Your week.

Swiss knife — Salt edition Swiss knife — Silicon edition
Mon

Tool graveyard

You're paying for tools nobody uses. Two overlap. One was set up by someone who left in October. The login is in a Slack thread somewhere. You keep meaning to cancel.

Tue

Slop machine

The content your agency sent reads like it was written by a slop machine. You rewrite half of it yourself. Again. You used to have standards. Now you have deadlines.

Wed

The differentiator question

A client asks what makes you different. You start talking. Halfway through you hear yourself saying the same thing your competitors say. You finish the sentence anyway.

Thu

Half their size

Your competitor just launched something that looks suspiciously like what you've been "planning" for six months. Their team is half the size of yours.

Fri · Critical

Stock photos.

You open your inbox to a consulting firm promising to "transform your organisation." Their website has stock pictures and a broken chatbot. You close the laptop and pour a drink...

And somewhere between all of that, you're supposed to be building something you're proud of.

That's the GAP.

What does Salt & Silicon do?

We are a frontier studio based in Barcelona. We do strategy, design, product, growth engineering, coaching, and AI education for brands, founders and growth teams. If it touches your growth, we probably do it.

We have worked with governments, biotech companies, blockchain startups, e-commerce brands, tourism, defence. We run a Lab with free tools, experiments and inspirations. We also have a Journal where we write about design, growth engineering, data, productivity, and what it means to create something real in an age of simulation.

What makes us different?

Every founder now has the same AI tools. The output is infinite. What is hard is knowing which output is good. We think that skill, recognising quality, is the most valuable thing in the room right now. And it is what we do.

We are two people with a network of collaborators we trust, and systems that let us move like a much larger team. You talk to us, you work with us. No account managers, no juniors learning on your project.

How much does it cost?

Audits start from EUR 999. Bigger projects are scoped during a discovery conversation so you know exactly what you are paying for. Coaching is available by session or retained.

Every project starts with a free 30-minute call. You walk away with an honest read of where you are, whether we work together or not.

Who is this for? Who is it not for?

For the founder doing EUR 1-50M who feels the gap between what they put out and what they know they are capable of.

For the CMO who cannot tell anymore what is good and what is filler.

For the creative director who sees the slop and cannot unsee it.

For the hiring manager who feels the AI wave coming and does not know where to stand.

For the non-profit that needs to do more with less and refuses to look cheap doing it.

We are not the right fit if you want growth at all costs, dark marketing tactics, or a team that just says yes. We challenge things. That is part of the work.

Can two people really deliver?

We designed this website and this brand ourselves, with a limited budget and conviction. Every pixel, every animation, every word. Now imagine what we could do with yours.

We know growth engineering: we use AI systems to enhance human work. We take risks. We are underdogs and we adapt. Structured enough to execute. Fluid enough to find the thing nobody expected.

Where are you based?

Barcelona, in the Eixample district. Gaudí built organic curves grown from nature and obsession. Cerda designed the grid of streets around them, rational and scalable. That tension between the two is where our name comes from. We have lived and worked in the US, China, Europe, Iceland. We work with clients everywhere.
