KAUFAST is an IT services company founded in 2004, specialising in AI agents, business automation, cloud infrastructure, and custom software development. With offices across six countries including London, Barcelona, and Chihuahua, KAUFAST builds enterprise-grade technology for ambitious businesses worldwide.
A foundry of tech developers anchored in Barcelona and London, with a footprint across six countries. KAUFAST is where strategy meets deep technical execution. We forge enterprise-grade AI, automate complex workflows, and architect custom platforms engineered for absolute performance.
We are a technology studio that builds software with precision. To create platforms and digital products, we combine bold engineering with obsessive attention to detail.
We audit before we build. Every engagement starts with a forensic review of your stack, your bottlenecks and your goals — so the first thing we ship is clarity.
We architect for resilience. No over-engineering. We find the simplest, fastest path to a system that scales — then build it to survive real-world load.
We deliver outcomes, not hand-offs. Every system we ship is production-ready, measurable and something your team actually wants to use.
Clarity before code. We map your exact constraints, workflows, and technical debt to build a clear roadmap of where technology can unlock growth.
Turn AI into operational leverage. We deploy intelligent systems and secure cloud infrastructure designed to scale effortlessly across your business.
Design meets engineering. We build lightning-fast digital products, apps, and platforms engineered for maximum conversion and flawless UX.
Security without compromise. We fortify your infrastructure at every layer with enterprise-grade threat mitigation and rigorous compliance.
From AI agents to cloud infrastructure, we follow a five-phase methodology — discovery, architecture, development, deployment, and support — so every project delivers measurable results.
From intelligent agents to workflow automation, we embed AI at the core of your operations — automating decisions, reducing costs, and building capabilities that scale without adding headcount.
We architect cloud-native systems on AWS, Google Cloud, and Vercel — secure, resilient, and optimised for performance. From migration to monitoring, we handle the full stack.
From internal dashboards to customer-facing applications, we build bespoke software that solves real business problems — web, mobile, and API-first, with enterprise-grade standards.
We design, build, and scale technology for businesses — AI agents, cloud infrastructure, custom software, and cybersecurity. Strategy first, then execution. In practice, that means building WhatsApp bots that handle thousands of customer conversations without a human in the loop. Architecting cloud infrastructure on AWS, GCP, or Azure that stays up when traffic spikes. Writing software that replaces manual processes your team does every week. And securing the systems that run your business. Every engagement starts with understanding the problem — not the technology.
A senior-led team works on every engagement — engineers, architects, and strategists handpicked for each project. No layers, no handoffs, no outsourcing. When you speak to us in the first call, you're speaking to the people who will build your product. We don't pass your work to a junior team in another timezone after the contract is signed. The person who scopes the architecture is the person who writes the code. That's how you get consistent quality — and why our clients stay for years, not projects.
Both. From founders shipping their first product to enterprise teams modernising legacy systems. Our process scales to match the challenge. For early-stage founders, that means fast MVPs with clean architecture that doesn't need to be rebuilt at Series A. For enterprise clients, it means integrating AI and automation into systems with years of legacy debt — without breaking what already works. We've helped bootstrapped products reach enterprise revenue, and we've helped enterprise teams move at startup speed. The approach is the same. The scale isn't.
Speed is built into our model. A focused automation or AI agent — a WhatsApp bot, a lead qualification workflow, a data pipeline — ships in 2–4 weeks. A full mobile app or web platform ships in 3–4 months with usable features delivered every two weeks, not one big reveal at the end. Enterprise platform migrations run 6–12 months with measurable milestones along the way. We define scope and milestones before we start, and we hold to it. No vague estimates. No surprise delays.
We don't disappear. Launching is the start of the work, not the end. We offer 24/7 system monitoring so problems are caught before your users notice. Incident response when something breaks — fast. Performance tuning as your traffic grows. Feature development as your product evolves. Some clients run on a monthly retainer for continuous development. Others call when they need specific work done. Either way, we're available. Your systems are our responsibility, not just our previous work.
