AI-first consulting · Strategy, innovation and growth
Your business has the potential. I help it grow with judgment.
I help founders and leadership teams at businesses and startups bring order, technology and artificial intelligence to their growth — with the experience of having founded, scaled and run companies for 25 years, not of having observed them from the outside.
Does this sound like you?
You're growing, but without a system.
Revenue is up, processes live in spreadsheets and WhatsApp, and no one has a full picture of how your company actually runs.
You're stuck, and you're not sure why.
The business works, but it's stopped taking off. What's missing is a layer of strategy connecting what you do today to where you want to go.
You've just validated your product and need to scale.
You have traction, but you're missing go-to-market structure, processes and judgment to avoid repeating mistakes that are already avoidable.
If you recognize yourself in any of the three, keep reading.
What I do — and how I do it
I work alone, but not in isolation. I identify what your business needs, design it, and when it's time to execute, I do it myself directly or coordinate the right specialists — hired by me or directly by you, whichever makes more sense for the project. I never sell hours from people you don't know.
Diagnosis and strategy
A free initial audit and, if we move forward, an honest diagnosis of where your business stands and what it needs to grow with order. No crystal ball: a full map of people, processes, tools and real bottlenecks.
Systems, ERP and applied AI
Design and implementation of management systems (Odoo and similar), process automation and AI agents applied to concrete business tasks — quoting, data analysis, customer service, back office. When a project requires specialized software architecture or backend development, I quote it as a separate line item and it's subcontracted to an external technical team, hired by me or directly by you.
Brand, content and acquisition
Brand strategy, website, acquisition funnels and CRM. Design of the digital presence your business needs to attract customers predictably — not just to "have a website".
Spaces and experience
Diagnosis of workspaces and client-facing spaces, with a clear playbook of real business needs — especially useful if your project involves renovation, space design or physical client experience.
Funding
Private investment rounds, public grants, other funding sources, competitions and tenders. I help you prepare all the material, score the opportunities, and handle follow-up, negotiation and closing.
People and processes
Diagnosis of your internal processes, your team's structure and the talent you have. Includes a satisfaction pulse-check to find out how your people really feel, catch friction early, and understand what's actually holding the business's growth back.
Not every project ends the same way. Some end with a report and a roadmap that you execute yourself. Others include full implementation. And some continue with ongoing follow-up once the system is running. We decide together based on what your business needs, not on a pre-packaged bundle.
How I work
Free audit
A first, no-cost call to understand your business and decide together whether it makes sense to move forward.
Book a callAnalytical
A full mapping of the ecosystem: people, processes, tools and flows. An honest diagnosis before proposing any solution.
Executive
A concrete action plan and real implementation — systems, AI agents, processes. I don't deliver pretty proposals: I deliver things that work.
Systemic
The system keeps running without depending on me. Optional follow-up to make sure it holds over time.

About me
I'm not a theoretical consultant.
I'm Diego Serrano. For 25 years I've founded, scaled and run companies — not observed them from the outside. I founded and was CEO of Broomx Technologies, an immersive-tech and AI SaaS platform operating in 24 countries, which I scaled from zero to over €4M in cumulative revenue. I raised over €3M in funding with Wayra Telefónica and Banco Sabadell, and successfully led its restructuring and acquisition process in 2025.
Before that, I founded and ran SerranoBrothers, a design and innovation studio with 25 years of track record, working for brands such as BMW, LEGO, Nestlé, Adidas and Meliá Hotels.
Today I apply all of that — strategy, technology, design and judgment — to businesses at the point I myself have been at many times: growing without a system, or needing to take the next leap.
I work with clear fees from day one, and the first meeting is always free.
