Valmsero is a London-based custom software studio. We build web platforms, mobile apps, and backend systems for ambitious teams since 2016.
Founded in 2016 in London, United Kingdom, Valmsero started as a two-person consultancy in a small Shoreditch studio. Today we’re a team of 18 specialists — developers, designers, and product thinkers — who have shipped over 70 successful projects for startups, agencies, and established companies across Europe.
We believe in clean architecture, honest communication, and software that actually solves problems. Every engagement begins with understanding your domain, not just your tech stack.
Our clients stay with us for years because we treat their product as our own. From MVP to enterprise-grade platforms, Valmsero delivers.
Our portfolio spans fintech, healthtech, logistics, and e-commerce. We also maintain several open-source tools used by thousands of developers.
React, Next.js, Vue, and Node.js. We build performant, accessible frontends and robust APIs that handle real traffic.
Native iOS (Swift) and Android (Kotlin), plus cross-platform with Flutter and React Native. Clean UX and smooth performance.
Scalable microservices, serverless architectures, AWS/GCP/Azure. We design systems that don't break at 3 AM.
Code audits, architecture reviews, team augmentation. We help you make better technology decisions.
We map your domain, user needs, and constraints. No assumptions — just research and whiteboarding.
Interactive mockups and architecture diagrams. You see exactly what we’ll build before a single line of production code.
Two-week sprints, continuous deployment, and transparent reporting. You always know the status.
We deploy, monitor, and support. Then we iterate based on real usage data — because software is never truly finished.
