Bespoke software development for UK companies
Doomity LLC is a US software engineering firm that works remotely with clients in the United Kingdom. We do not have an office in London — and we would rather say so in the first line than have you discover it in the first meeting. What we do have: engineers who have built for Holcim, Canon España and Indra, a working day that overlaps UK hours almost entirely, and a published method you can audit before talking to anyone.
Why does working remotely with the UK actually work?
Three practical reasons, verifiable from day one. First: the hours. The team works from Western Europe (WET/CET), which means your 9-to-5 and ours overlap almost completely — meetings book inside your working day and answers arrive the same day, not the next. Second: the language. English is the working language for meetings, deliverables and documentation; contracts are drafted in English by default. Third: the process. Remote delivery only fails when the vendor improvises; our method is published step by step, and every phase produces dated deliverables you can verify without leaving your office.
What experience does Doomity have that UK companies can check?
Doomity LLC is a software development firm specializing in custom software, legacy modernization, AI prototype-to-production, software project rescue and technical due diligence, serving clients in the US, UK, Spain and Portugal. Its engineers come from teams that have built for Holcim, Canon España and Indra — enterprise systems under high demand and heavy data volume.
On named case studies, the honest position: we only publish cases with the client's written permission, and we would rather publish none than invent them. What you can verify today: the complete method, the free diagnostics, and the technical quality of this very site, built with the same process we are proposing to you.
Which services does Doomity provide to UK businesses?
- Custom software development — when the workflow is your competitive advantage and bending it to a generic product would cost you money.
- Legacy modernization — when the system holding the business up is one nobody wants (or can) maintain any more.
- AI prototype to production — when the prototype built with Lovable, Bolt or Cursor has to survive real users.
- Software project rescue — when the project has derailed and you need someone to take over the repo and stabilise it.
- Technical due diligence — when there is a round or an acquisition and the technology has to survive scrutiny.
Every engagement starts the same way: a 25–30 minute call with a senior engineer and, if it makes sense, a 5-day fixed-scope diagnostic Sprint with guaranteed deliverables. The full process is documented at how we work.
How do you contract a US company from the United Kingdom?
With less friction than it sounds, because the circuit is standard for international B2B services. Doomity LLC invoices as a US company with no UK permanent establishment: for B2B services bought from abroad, UK VAT is accounted for by your company under the reverse charge — the invoice arrives without VAT and your accountant handles the entry, a mechanism any UK bookkeeper knows well. We provide the W-8BEN-E form your company needs for withholding documentation, and invoicing is in US dollars or pounds sterling, as agreed in the contract.
The contract covers what matters: scope, dated deliverables, full code ownership from the first commit (repository and cloud in accounts you own) and a written IP assignment. No small print: we guarantee process and deliverables, never outcomes — a vendor promising revenue for software that does not exist yet is selling you their forecast, not their engineering.
FAQ
No. Doomity LLC is a US company that works remotely with UK clients, and we say so openly because the alternative — a virtual address to look local — is exactly the kind of facade we advise clients to avoid in any vendor. Meetings run over video call inside UK hours, and the work is verifiable at every phase: repository, deliverables and demos in your environment.
Western European hours (WET/CET), which overlap the UK working day almost entirely — the offset is zero to one hour. Meetings book inside your 9-to-5 and written communication is answered the same day. No night shifts, no 12-hour waits for a reply.
US dollars or pounds sterling, as agreed in the contract. The invoice is issued by Doomity LLC (US) without UK VAT: for B2B services imported from abroad, your company accounts for VAT under the reverse charge mechanism. We provide the W-8BEN-E for your tax documentation.
A services agreement with Doomity LLC covering scope, dated deliverables and full assignment of intellectual property to you. Contracts are drafted in English; governing law is agreed per engagement — US contract by default, with alternatives discussed case by case. Repository, cloud and CI are set up in accounts you own from kickoff.
Sometimes you should hire the UK agency — if daily on-site presence matters more than anything else, we are the wrong choice and will say so on the first call. What Doomity offers instead: senior engineers you talk to directly (no account-manager layer), enterprise delivery experience, full UK-hours overlap, and pricing that is not London pricing. The deliverables are designed so any competent team could take over — which is exactly what makes it safe to work with a remote vendor.
