Enterprise Software Development Company in London, built to ship.

Legacy systems do not get replaced overnight, and pretending otherwise is how migrations fail. We work as a build partner to modernize them in place, build custom ERP and CRM applications around how you actually operate, and connect siloed tools into one platform. The engineering rigor your compliance and security teams expect is the default, and we deliver inside your existing change management and review processes rather than around them. London (GMT, or BST in summer) sits 5.5 hours behind India (IST), which is the most convenient overlap of any major Western market because your morning is our afternoon and the two working days share a large chunk of live, productive hours.

Compliance in United Kingdom

How does Enterprise Software Development stay compliant with UK GDPR in London?

London companies build under the UK GDPR and the Data Protection Act 2018, overseen by the Information Commissioner's Office (ICO). We design every enterprise engagement to respect those rules from day one, not as a checklist bolted on at the end. Moving personal data from the UK to India relies on safeguards such as the International Data Transfer Agreement, which we put in place so your processing stays lawful end to end.

Who regulates you

the Information Commissioner's Office (ICO). the FCA layers extra operational-resilience and outsourcing expectations on financial services, which we design around for regulated clients.

Where your data lives

You pick the hosting region. When residency rules or a United Kingdom contract require it, we deploy inside your jurisdiction and you hold the cloud accounts.

What you own

100% of the source code and IP, transferred under contract, with an NDA and a data processing agreement signed before anything is shared.

Proof we can do this at scale: the products we have shipped run at 250K+ daily active users and have handled 10M+ requests per minute, across 50+ products rated 4.9 stars over 24+ client projects. Security and data handling are part of how we build, not an afterthought.

FAQ

Enterprise Software Development in London, answered

How do you migrate legacy systems without disrupting operations?
We use the strangler fig pattern, building new functionality alongside the legacy system and gradually routing traffic to the modern platform. The old system stays running until the new one is fully validated, which removes the risk of a big-bang cutover and keeps revenue-critical processes online throughout.
Can your enterprise software development team work within our compliance framework?
Your process is the one we adopt, not ours. We adapt to your change management, security review, and deployment procedures, and we have worked within SOC 2, ISO 27001, and industry-specific frameworks. Code is built to be audit-ready from the first commit so security and compliance reviews do not become a bottleneck.
What if we need to integrate systems that have no modern API?
We build integration layers using database replication, file-based transfer, or custom middleware, matching whatever the older system supports. We have connected mainframes, AS/400 systems, and custom tools from the 1990s into unified platforms with a reliable single source of truth.
How much of the working day do London and India actually share?
London is 5.5 hours behind our India team, which gives one of the best overlaps we work with. Your full morning is our afternoon, so live calls, code reviews and approvals happen in real time without anyone working unsociable hours.
Is offshore development with Geminate Solutions more cost-effective than a London agency?
London carries some of the highest developer rates in Europe, so an offshore product partner usually reduces your build cost substantially while keeping delivery quality high. We scope the exact cost on a call once we understand your product, rather than listing a headline rate.
How do you handle UK GDPR and data protection for London clients?
London businesses fall under the UK GDPR and the Data Protection Act 2018, overseen by the Information Commissioner's Office (ICO). Moving personal data from the UK to India relies on safeguards such as the International Data Transfer Agreement, which we put in place so your processing stays lawful end to end. Before any data is shared we sign an NDA and a data processing agreement, and the FCA layers extra operational-resilience and outsourcing expectations on financial services, which we design around for regulated clients.
Where will our data and code be hosted if we build with you from London?
You choose the region. We default to a cloud setup that satisfies UK GDPR obligations, and when residency rules or a United Kingdom contract require it, we host inside your jurisdiction. You keep full ownership of the source code, the data, and the infrastructure accounts at all times.
How much does Enterprise Software Development cost in London?
Every enterprise project is scoped on a free call rather than sold as a fixed package, and most engagements start with a paid pilot sprint so you see the work before you commit. You get a clear number in GBP before anything starts.
Do we own the code?
Yes, completely. The code, the project, and the content are handed to you. You hold the keys, not us. We sign an NDA before you share anything.
How long does it take?
Most builds go live in two to four weeks. Larger products with a custom backend or migration take longer, and you get a firm timeline before any work begins.
