Software we've built for US and international clients
Why US teams come to us
If one of these is your situation, this is how we handle it.
A US agency quoted a rate that eats the whole budget before the first sprint.
Senior talent at offshore rates. Years of production experience on US and UK products, plain-English communication, and real overlap with EST through PST. Fixed-price, scoped before we start.
You have a roadmap for the year and no team to build it.
A dedicated pod or embedded engineers. The same senior people who shipped COMPASS for Ball State and the software behind Sharewear, on your roadmap, in your overlap hours. See dedicated development team.
You handle health or payment data and need it built right.
Compliance-aware architecture. OWASP Top 10 as a baseline, plus HIPAA-aligned data handling where it applies. COMPASS was built to the data-handling requirements of clinical research at an accredited US university.
A previous build stalled and the team that started it is gone.
We audit, then take over delivery. A straight assessment of what is salvageable, then fixed-price phased recovery. See software project rescue.
Built by AI-native engineers, so AI is a feature ticket, not a rebuild
Every build we deliver for a US client is architected so language-model features go into your data and workflow when you want them. We design the schema, APIs, and event streams for it from phase one. It is how we built our own products, Tully AI and Mebag.
In-app copilots, drafting, and summarisation wired into the product your team already uses, with humans in control.
RAG over your records, so a plain-language question returns a grounded answer.
Multi-step workflows wired into your systems, with guardrails, evals, and human approval on anything sensitive.
Shipped with prompt versioning, eval suites, and guardrails. See how we build AI →
Why US companies work with Teamseven
The same reason our US clients come back for their next project: we treat your product like it's our own, we communicate in plain English, and we ship what we say we'll ship.
Time zone coverage
We work across US time zones. Our team maintains overlap with EST, CST, MST, and PST for standups, demos, and urgent communication. You won't be waiting until tomorrow morning for answers.
US-standard contracts
We work with US-standard NDAs, IP assignment agreements, and project contracts. Intellectual property transfers to you on final payment. No ambiguity about who owns what you paid to build.
Senior talent at offshore rates
Our rates are a fraction of a typical US agency's rate for comparable senior talent, without the trade-off in quality. Our engineers bring years of production experience on US and UK products.
What we build for US clients
Every block is a service we deliver end to end for US startups and enterprises, fixed-price and scoped before we start.
SaaS MVP Development
From idea to deployed product. We've built SaaS MVPs for US founders across healthcare, logistics, fintech, and enterprise software. Typical timeline: 12–20 weeks.

Learn moreAI Development & Agents
LLM features, RAG pipelines, and AI agents wired into your platform, with evals and guardrails from day one. Built by engineers who ship AI to production.
Learn moreSoftware Project Rescue

Learn moreWeb Application Development
Portals, dashboards, and multi-role interfaces for US teams and their customers, built on a stack that scales.
Learn moreMobile App Development
iOS, Android, React Native, and Flutter apps for the US market, on a shared backend a web app can grow into.
Learn moreHow a US build actually runs
The same track on every engagement. You always know which phase you're in and what unlocks the next one.
Scoping call & proposal
A 30-minute working session in your time zone. We map the problem and the outcome, then send a fixed-price proposal with a clear scope and timeline, usually within two working days.
Kickoff & onboarding
A kickoff call with the engineers doing the work. Access and accounts set up in week one, a shared Slack channel, and an agreed weekly rhythm in EST–PST hours.
Design & technical planning
Scope turned into screens, a data model, integration points, and a build order. You review and sign off before code starts in earnest.
Build & weekly review
Development in weekly cycles, twice-weekly written updates, and a working environment you can click through. Scope changes are documented and priced as they happen, not saved for the final invoice.
Launch & handover
Production deployment with CI/CD, monitoring, and error tracking. Full Git access, a documentation file, and two months of free bug fixes on what we built.
Iterate or hand off
Most clients move to a monthly retainer for the next features, prioritised against real usage. You can also take the codebase fully in-house, or pause.
Built for the US market
A recent example of what we've delivered for a US client.
COMPASS for Autism, Research Platform
COMPASS for Autism is a research group at Ball State University focused on improving outcomes for children and adults with autism spectrum disorders. Teamseven built their web application platform, a tool used by researchers, educators, parents, and autism consultants across the United States to build personalized support profiles and manage intervention research.
Built to the data-handling requirements of clinical research at an accredited US university, and run by a non-technical research team.
Building something for the US market?
30 minutes, in your time zone. We'll look at your project and tell you honestly if we can help, and what it would take.
Book a scoping callThree ways to engage us
A founder with an idea, a product team with a roadmap and no hands, and a team stuck with a stalled build need different things. Pick the one that sounds like you.
Fixed-Price Build
You know roughly what you need. We scope it, quote a fixed price and timeline, and build in stages with a working demo each week.
Fixed-price and MVP buildsYou have a team, not enough handsStaff Augmentation
You have engineers and a roadmap but need senior developers who have shipped US products embedded in your team, in your overlap hours.
IT staff augmentationYou inherited a stalled buildSoftware Project Rescue
A previous team is gone and the build stalled. We audit what exists and tell you honestly whether to extend, refactor, or rebuild.
Project rescue and modernizationCommon questions from US clients
Are you able to work with US time zones?
Yes. We maintain overlap with US East Coast and West Coast time zones for daily standups, sprint reviews, and ad-hoc communication. For urgent issues, our team is reachable outside standard hours.
How do contracts and IP ownership work?
We use standard professional contracts with full IP assignment to the client on final payment. We're comfortable with NDAs and work-for-hire agreements. All code and deliverables are yours.
Do you accept USD payments?
Yes. We invoice in USD and accept payment via bank transfer, wire, and most major payment platforms. No currency conversion overhead for US clients.
How do I get started?
Book a free 30-minute consultation. We'll talk through your project, ask the right questions, and tell you honestly whether we're the right fit, and if not, why not.
Can you build AI features into our software?
Yes, and we architect for it from the start. Our engineers are AI-native: LLM features, RAG over your own data, and agents that take actions all drop in as a feature ticket rather than a rewrite. When we build AI in, it ships with prompt versioning, eval suites, and guardrails. It is the same approach we used for our own products, Tully AI and Mebag.
