For US Teams
Software Development Partner for US Companies
VaultFifty1 partners with US companies as their engineering team: senior developers across software, cloud, DevOps, security and AI, working with real overlap into US hours. You get the engineering standards your customers and investors expect — threat modelling, code review, CI/CD, monitoring — at economics that don't require a US payroll, and you own every line of code and every account from day one.
Is this you?
- You're a US startup that needs senior engineering without spending a seed round on salaries.
- You've tried low-cost outsourcing before and got code you had to rewrite.
- You need a partner who can pass your customers' vendor security reviews, not just ship features.
What you get
Real working-hours overlap
We structure the team so you get genuine overlap with US time zones for standups, reviews and incidents — not a 24-hour round trip on every question.
US-grade engineering standards
Threat modelling, code review, CI/CD and monitoring on every build. Our security practices are documented openly, and we'll walk your team through them.
Full IP ownership
Contracts assign all work product to you. Repositories, cloud accounts and domains are in your name from day one, so leaving us costs you nothing.
One team, every layer
Software, cloud, DevOps, cybersecurity and AI under one roof, so you're not coordinating three vendors who blame each other.
How we work
- 01
Scope on your hours
A call in your working day to understand the product, constraints and what success looks like. A written plan and estimate follows, usually within one business day.
- 02
Meet the actual team
You talk to the engineers who will build your product before anything is signed. No bait-and-switch between the sales call and the sprint.
- 03
Ship in weekly releases
Working software every week, visible in your repos and your staging environment, with async updates that respect the time difference.
- 04
Stay for the long run
Monitoring, patches and iteration after launch, or a documented handover to the in-house team you build — we'll even help you hire it.
FAQ
Frequently asked questions
We plan the overlap deliberately: standups, reviews and anything interactive land in a shared window with your working day, and deep work happens in ours. In practice the offset works for you — issues raised at your end of day are often resolved by your next morning.
You do, contractually and practically. All work product is assigned to you, and repositories, cloud accounts and infrastructure are created in your name from the start. There is nothing to hand over at the end because you held it all along.
The failure mode of cheap outsourcing is junior code behind a senior sales call. We keep the team senior, put security and review into the definition of done, and show our work — our practices are public, and you meet the engineers before you sign. If price is the only criterion, we're honestly not the cheapest option.
Yes, and it's common: we extend in-house teams, own a workstream end to end, or pair our security and DevOps depth with your product engineers. We fit into your process, tooling and review culture rather than imposing ours.
