We design, build and support SaaS platforms, web and mobile apps, and AI features for startups and growing businesses.
Most clients come to us in one of these four situations.
Where you are
What you walk away with
A working product in front of paying users within two months, not a year-long build you validate at the end.
Where you are
What you walk away with
One system with proper permissions, an audit trail and automatic reports. Hours of admin gone every week.
Where you are
What you walk away with
We fix what's actually losing you users, whether that's confusing screens, slow pages or a stack that can't scale.

DevEntia Tech is a UK-registered custom software development company with an office in London and an engineering team in Islamabad, Pakistan. We design and build SaaS platforms, web applications, mobile apps (Flutter and React Native), AI and machine-learning features, and cloud infrastructure. We also provide UI/UX design, QA, DevOps, SEO and staff augmentation. We have delivered 100+ projects for 40+ clients worldwide since 2020, including the USA, UK, UAE and Australia.
Web applications start from $3,000 and SaaS platforms start from $5,000 for an MVP. Full-featured platforms typically range from $10,000 to $50,000+ depending on complexity, integrations and compliance requirements. We provide a free, detailed, fixed estimate after a scoping call — and the price only changes through a change request you approve in writing.
A simple web application or MVP takes 4 to 8 weeks. Mid-complexity applications take 8 to 16 weeks. Complex SaaS or enterprise platforms take 4 to 6 months or more. Every project runs in two-week sprints with a demo at the end of each sprint and an always-current staging URL.
You do, from the first commit. Source code, Git repositories, cloud accounts, design files, domains and credentials are registered in your name and handed over at the end of the engagement. We will sign an NDA before any discussion if you prefer, and there is no vendor lock-in of any kind.
Yes. A large share of our clients are startups building their first product. We work in phases — start with a lean MVP, put it in front of real users, then scale what works. We are candid about what can be cut from version one to protect your runway.
Yes. Through staff augmentation we place vetted senior engineers, designers, QA and DevOps specialists directly into your team, using your tools, your standups and your codebase. You can scale that capacity up or down month to month without recruitment overhead.
UK clients work with our London office and a +44 number. Engineering runs from Islamabad (UTC+5), which overlaps the UK and European working day by four to five hours and the US East Coast in its early morning. You get a named project manager, Slack or your preferred channel, written weekly updates and scheduled video calls.
We handle deployment, app store submission, monitoring setup and handover documentation. After that most clients move onto a support retainer covering bug fixes, security patching, performance monitoring and continued feature work. You are never required to take one — everything is documented so your own team can take over.
One form, one call, and you'll know what it takes and what it costs. No obligation.
Free, no obligation. Stage 01 of the process above.
