Your market

Building for London

London is one of the world's great financial centres and the UK's main technology hub. The City and Canary Wharf hold banks, insurers, the Lloyd's market and asset managers; Shoreditch and King's Cross host a dense fintech, AI and startup scene; and the legal, consulting and media sectors run on large volumes of documents and client data. AI projects here sit inside regulated environments, so FCA expectations, UK GDPR and procurement checks shape what gets built as much as the technology does. Clear audit trails, careful data handling and a human approval step on anything that touches money are the norm, not an extra.

FAQ

Questions from London companies

How much of the London working day do you overlap?

Nearly all of it. Mumbai is 5.5 hours ahead of London in winter and 4.5 in summer, so your 9am is our early afternoon. We run a shifted day for UK work, so standups, workshops and demos sit across your morning and afternoon without anyone working through the night.

Can you build to FCA and UK GDPR expectations?

Yes. For financial-services work we build in audit logging, role-based access and approval gates wherever money or customer data moves, and document the system so your compliance team can review it. We are not FCA-authorized ourselves — we build the controls your authorized firm needs.

Do you contract in pounds?

Yes. Scope, milestones and invoices are in GBP, under a contract that assigns all code and IP to your company. Discovery is short and paid, so you see a fixed price before committing to the build.

Who owns the code and IP?

You do, completely. Repositories, cloud accounts and all IP transfer to you, documented at handover — including anything produced during discovery.

How do payments and contracts work?

A short paid discovery, then a fixed-scope contract with milestone payments as you approve working software. We sign NDAs and data-processing agreements and invoice in your currency.
