Manchester-headquartered. Independently owned. Client-driven. Since 1999 we have delivered mission-critical software for organisations that cannot afford to fail — from UK defence primes to ambitious SMEs.
bitConcat was founded on a straightforward premise: organisations deserve software built to the standard their operations actually demand — not the standard that is cheapest or fastest to ship.
Over 25 years we have built software systems for some of the most demanding environments on earth — defence operational theatres, trading floors, national digital infrastructure, and the operational backbone of businesses across 40+ countries.
What has never changed is our belief that security, reliability and technical integrity are not optional extras. They are the baseline from which every engagement starts — whether the client is a defence prime or a 10-person startup.
Our growth has always come from the success of the organisations we serve — not from investor pressure to scale faster than quality allows. We remain independently owned and intend to stay that way.
bitConcat established with a focus on enterprise application development for financial services clients.
First engagement with UK defence supply chain — a safety-critical logistics platform delivered under NDA.
Delivery footprint extended to 20+ countries. Nearshore engineering capability established.
Dedicated cyber security and intelligence practice launched in response to growing client demand.
Full cloud-native and SaaS platform engineering capability formalised. 40+ countries operating.
AI-augmented development tooling integrated — with senior human engineering oversight maintained at every stage.
These are not aspirational statements. They are the principles that have governed every engagement for 25 years.
Security is not a feature we add. It is the foundation everything else is built on — regardless of project size or budget.
We tell you what we genuinely think — including when a simpler or cheaper solution would serve you better. Long-term relationships matter more than short-term revenue.
We commit to timelines we believe in. Scope changes are managed with rigour and transparency. We do not disappear after go-live.
Every engineer at bitConcat maintains mastery of their craft. We invest heavily in learning, research and keeping pace with the evolving threat landscape.
Headquartered in Manchester, governed by UK law. Our leadership is accessible — not hidden behind a sales layer or an offshore management chain.
We grow because our clients succeed and return. That discipline — not marketing spend — shapes every decision we make.
We believe technology companies have a responsibility to the communities they operate in — and to the next generation of engineers entering the field.
We partner with Manchester schools and colleges to support coding education and digital literacy programmes for young people.
Active recruitment and mentorship of graduates and apprentices. We invest in developing engineers, not just hiring experienced ones.
Cloud infrastructure choices made with energy efficiency in mind. Responsible data handling embedded in every system we build.
We're always interested in exceptional engineers who share our values. bitConcat offers technically challenging work, exposure to genuinely complex real-world systems, and the satisfaction of building software that matters.
We do not have a revolving door culture. Our team tenure is long because we look after our people — with flexibility, meaningful work, and room to grow technically.
