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 companies and startups bring order, technology and artificial intelligence to their growth — with the experience of having founded, scaled and run companies for 25 years.
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 identify what your business needs, design it, and — when it's time to execute — carry it out myself or coordinate the right specialists, hired by me or directly by you, depending on what makes most sense for the project. I'm your Growth Partner: when I coordinate a third party, I act on your behalf, review what they propose, negotiate terms and oversee the result with the same judgment I applied when the decision and the risk were mine.
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 in an orderly way: business model, product, sales, marketing, finance, operations and team — including whether it's time to open new markets or expand geographically. I look at it with the same complete view I used when the chair was mine. No crystal ball, and no acting as your CFO, head of sales or product manager: I tell you where the real problem is.
Systems, AI and automation
I start by auditing which tools your team uses and where they're holding you back. From there, I design and implement management systems (Odoo and similar), and review or configure your project management systems so they coordinate teams and projects for real. I automate processes, build AI agents for specific tasks, and turn ideas into working MVPs with vibecoding in days, not months. AI, always where it changes the outcome — never because it looks good in a proposal. If the project needs specialized backend development, I quote it separately and subcontract it, hired by me or by you.
Brand, content, acquisition and sales
Brand strategy, website, online stores (Shopify, Wix), acquisition funnels, lead magnets and CRM: the digital presence your business needs to attract customers predictably. And the rest of the journey — I design your go-to-market strategy, the structure of your sales process (channel, funnel, qualification and close), and how to retain the customer you already have, not just win the next one. I'm not your salesperson and I don't make the calls for you: I design how your sales machine should work, start to finish.
Product and offer
I analyze and optimize your offer — a digital product (SaaS, info-products, apps) or a physical one —: whether it solves a real problem (PMF), whether it's viable to produce and bring to market, and whether it's worth protecting with patents or industrial property. I also bring creative direction: how the offer is designed, told and differentiated, with the same eye I used to lead product in my own companies. I don't replace your product or design team: I review, question and refine the offer before the market does it for you.
Funding and finance
Private investment rounds, public grants, other funding sources, tenders and public bids — I prepare the material, score the opportunities, negotiate and close. And I apply the same CEO-level view of pricing, margins and unit economics I used to decide where to put every euro when the money was mine: I don't do your bookkeeping, but I'll tell you if the problem is sales, cost, or price.
People and processes
A diagnosis of your internal processes, your team structure and the talent you have available. I include a satisfaction check to really know how your people are doing, catch friction early, and understand what's actually holding back the business's growth.
Not every project ends the same way. Some finish with a report and a roadmap you execute yourself. Others include full implementation. And some continue with ongoing support once the system is up and running. We decide together based on what your business needs, not on a fixed package defined in advance.
How I work

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.

About me
Diego Serrano — Innovation & Growth Consultant
I'm not a theoretical consultant.
I'm Diego Serrano. For 25 years I've founded, scaled and run companies. 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.
