# Xavi Creus > Xavi Creus is a Barcelona-based tech CEO and serial entrepreneur running SaaS and AI companies with more than €10M in annual recurring revenue, a team of 100+ people and customers in 20+ countries. He builds with software and AI, studies it obsessively, and helps friends and founders think clearly about technology. ## Who I am a multidisciplinary engineer by training and a CEO by trade. For the last ten years I have built and scaled software companies: SaaS products, AI products and the teams behind them. Today that is more than five companies, over a hundred people and customers in more than twenty countries, run from Barcelona as CEO of Tendios. I still write code, and I still read the papers. I spend an unreasonable amount of time on books, podcasts, videos and research about AI and technology, and I test everything I learn on real businesses with real revenue. That combination, operator plus student, is the whole point. Before Barcelona I lived and worked in Vienna, Braunschweig and Coventry, and I have travelled to more than sixty countries. I speak Catalan, Spanish, English and German, and I studied at London Business School. - Based in: Barcelona - Role: CEO, Tendios - Education: London Business School - Languages: Catalan · Spanish · English · German - Circles: Círculo Ecuestre · Club Porsche - Credentials: PMP · SAFe Agilist · Certified ScrumMaster ## In numbers - €10M+ annual recurring revenue across the companies I run - 5+ SaaS and AI companies - 100+ people on the team - 20+ countries we sell in - 60+ countries I have visited - 10+ years building businesses ## Conversations he is happy to have - What should AI actually change in my business? Separate the demo from the deployment. Which processes a model can already run, which ones need a person in the loop, and what to leave alone for now. - How do I build a software product without a CTO? Scope, stack, team and cost for a first version, plus the questions to ask any agency or developer before you sign anything. - Is this technology real or hype? A plain-language read on tools, vendors and trends, from someone who has bought, built and thrown away plenty of them. - How do I take a company to twenty countries? Product, pricing, payments, languages and the operational plumbing that turns a local business into an international one. - How do I use AI myself, today? The concrete stack I use every day to write, research, code and decide faster, and how to set it up for a non-technical team. - Should I invest in, buy or start this? An operator’s view on a deal, a product or an idea: what it takes to build, what it costs to run, and where the moat really is. ## What he believes about the next ten years - Software stopped being the bottleneck. Anything that can be specified can be generated. The scarce skills now are choosing the right problem, distributing the product and knowing when to stop. - Every company becomes an AI company, or a customer of one. The question is no longer whether to use it. It is which of your processes it runs first, and who in your team is accountable for it. - Agents will do most of the work. People will do the deciding. The founder of this decade designs the machine, sets its principles and makes the few decisions machines should not. - The advantage is adoption speed, not the model. Models become commodities within months of release. The gap opens between companies that rewire how they work and those that wait for it to settle. - Small will beat big. One person with the right system can run what used to take a building. Expect more companies, smaller and more profitable. - Europe is under-built. One continent, many countries, under-served in almost every vertical. The next decade of software is a European opportunity. ## Technology he works with - AI: LLMs, AI agents, RAG, Fine-tuning, Evals, Prompt engineering, MCP, Machine learning, Deep learning, Computer vision, NLP, Speech, Vector databases, AI governance - Models & tooling: Claude, GPT, Gemini, Llama, Mistral, Anthropic API, OpenAI API, Hugging Face, PyTorch, TensorFlow, scikit-learn, LangChain, LlamaIndex, Claude Code, Cursor - Build: TypeScript, JavaScript, React, Next.js, Node.js, Vue, Nuxt, Python, FastAPI, Django, NestJS, Go, Java, Kotlin, Swift, .NET, PHP, Laravel, React Native, Flutter, Tailwind CSS, shadcn/ui, GraphQL, REST, Prisma - Data & infrastructure: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Kafka, RabbitMQ, Supabase, Firebase, AWS, Google Cloud, Azure, DigitalOcean, Vercel, Cloudflare, Docker, Kubernetes, Terraform, GitHub Actions, Playwright, Vitest, BigQuery, Snowflake, dbt - Business systems: Stripe, HubSpot, Salesforce, Segment, Figma, Linear, Notion, Slack, Google Workspace, Zapier, n8n ## Free-time project Aurum VOS (https://aurumvos.com/): In my spare time I am building Aurum VOS, a venture operating system: a shared platform, a foundry and governed AI agents that can launch, run and retire small software companies faster than people can.
