For UK Teams

Software Development Partner for UK Companies

VaultFifty1 partners with UK companies as their engineering team: senior developers across software, cloud, DevOps, security and AI. India's time zone gives us most of the UK working day in common, so collaboration feels local while the economics don't. Data handling is GDPR-aligned by default, security is part of our definition of done, and you own all code and accounts from day one.

Is this you?

  • You're a UK business that needs senior engineering capacity without London rates.
  • Your product handles personal data and your partner needs to take GDPR seriously, not nominally.
  • You want one accountable team across build, cloud and security instead of juggling agencies.

What you get

Most of your working day, shared

The UK–India offset leaves a long common window: standups, pairing and reviews happen live in your morning and afternoon, not by ticket relay.

GDPR-aligned by default

Data minimisation, clear processing roles, EU/UK data-residency choices and least-privilege access are standing practice, not a paid add-on.

Security as standard

Threat modelling, the OWASP baseline, CI security gates and a pre-launch review on every build — documented publicly on our security page.

Full IP ownership

All work product is assigned to you, with repositories and cloud accounts in your name from the start.

  3. 03

    Ship weekly

    Working software every week in your repos, with live collaboration through the shared working window.

    Monitoring, patches and iteration after go-live, or a clean documented handover whenever you want one.

FAQ

Frequently asked questions

Most of it. India runs 4.5–5.5 hours ahead of the UK, so your 9am is our early afternoon and we share the majority of your working day. Standups, reviews and urgent conversations happen live rather than overnight.

Data handling is GDPR-aligned by default: we minimise what we touch, keep processing roles explicit in the contract, support UK/EU data residency where your architecture needs it, and apply least-privilege access to any production data. Our data practices are documented on our security page.

You do. Contracts assign all work product to you, and repositories, infrastructure and accounts are created in your name from day one.

Yes. We can extend your in-house team, take a workstream end to end, or add the security and DevOps depth a design-led agency partner doesn't carry. We adapt to your process rather than imposing ours.
