From bespoke web platforms to mission-critical mobile apps — Ferslofb builds software that scales with your ambition. Founded in 2018, we are a London-based team of 14 engineers, designers, and strategists.
Start your projectFerslofb was founded in 2018 by two software engineers who saw how often custom development projects failed — missed deadlines, bloated specs, and communication breakdowns. We set out to build a different kind of dev shop: small, focused, and deeply collaborative. Based in London (our studio is at 15 Baker Street, W1U 3BW), we've grown steadily to a team of 14 specialists.
Over the past seven years, we've delivered more than 60 projects for startups, scale-ups, and established enterprises across fintech, logistics, and media. Our work ranges from high‑throughput trading dashboards to patient‑management platforms for the NHS. Every project is built with the same ethos: clean architecture, clear communication, and no shortcuts.
We are engineers who still write code. Our senior team averages over 12 years of experience, and we invest heavily in tooling, testing, and continuous delivery. The result is software that doesn't just work at launch — it stays reliable for years.
Why Ferslofb? Because we treat your product as if it were our own. We don't outsource, we don't overpromise, and we never disappear after launch. Every client gets a dedicated lead engineer, weekly progress reports, and a full post‑launch warranty. We're small enough to care, big enough to deliver.
Our clients include a London‑based fintech now processing £2B+ annually, a national logistics provider with 500+ fleet vehicles, and a media startup acquired by a major broadcaster. We are proud of every single one.
If you need a team that listens, designs, and engineers with precision — we're ready.
Enterprise‑grade platforms, internal tools, and APIs built with modern stacks (Go, Rust, .NET, Python, Node). We design for scale from day one.
React, Next.js, and Vue front‑ends with robust backends. We deliver fast, accessible, and maintainable web applications that users love.
Native iOS (Swift) and Android (Kotlin) apps, plus Flutter and React Native for cross‑platform. We focus on performance and pixel‑perfect UI.
Architecture reviews, cloud migration (AWS/Azure), CI/CD pipelines, and team augmentation. We help you ship faster with fewer incidents.
We spend up to two weeks understanding your domain, users, and constraints. You get a detailed specification, architecture diagram, and realistic timeline.
Two‑week sprints with demo at the end of each. You see working software from week three, not month six. We adjust based on your feedback.
Automated testing, staging environment, and a rollout plan. Post‑launch we provide 90 days of warranty, then optional ongoing support.
