CORE CAPABILITIES

From idea to infrastructure.

Custom SaaS and CRM are at the centre of everything we do. Everything else — AI, mobile, security, APIs, DevOps — exists to make those platforms faster, smarter, and harder to break.

Most requested

Custom SaaS Development

Multi-tenant platforms built from scratch. RBAC, subscription billing, admin tooling — architecture that holds at 10 users and at 100,000. We've shipped 200+ SaaS products across 12 verticals.

Custom CRM Development

Not Salesforce with a coat of paint. A CRM shaped around your pipeline, your data model, your team's actual workflow. We've built CRMs for logistics, healthcare, and enterprise ops.

AI Integration

LLMs, RAG pipelines, intelligent automation — wired into your platform. OpenAI, Anthropic, Gemini. AI that solves a real problem, not AI for the pitch deck.

Enterprise Software

Internal platforms, workflow automation, custom ERP — built for organisations where off-the-shelf hits its ceiling in year one.

Learn more

Web Applications

B2B portals, dashboards, data-heavy UIs. Angular, React, or Vue on the front. Node.js, .NET, or Python behind it. Stack picked for the problem.

Learn more

Mobile Apps

Native iOS, native Android, or cross-platform via React Native / Flutter — connected to your SaaS backend. We've shipped on both iOS and Android in production.

Learn more

API Development

REST, GraphQL, webhooks, third-party integrations. Secure, versioned, documented. The glue that makes your systems talk to each other without breaking at 3am.

Learn more

Cybersecurity & Pen Testing

OWASP, penetration testing, secure architecture reviews. We audit and harden SaaS platforms before a breach finds what you missed. GDPR, HIPAA, SOC 2 readiness built in.

DevOps & Cloud

CI/CD pipelines, Docker, Kubernetes, AWS/Azure. We ship fast and keep production healthy — monitoring, alerting, and zero-downtime deploys baked in from day one.

Learn more

Legacy Modernization

Old system, modern rewrite. We've migrated monoliths to microservices, moved on-prem to cloud, re-engineered architecture — without stopping the business while we do it.

Learn more

QA & Test Automation

End-to-end test suites, regression automation, load testing. We write tests that catch what manual QA misses — so your release doesn't become an incident at 11pm.

Learn more

UX/UI Design

Interfaces that your team actually uses. User research, wireframes, prototypes, visual design — everything that sits between your users and the backend doing all the work.

IT Consultancy

We provide expert guidance on all things IT, from strategy and architecture to implementation and optimization.

HOW WE WORK

From first call to production deploy.

No discovery theatre. No 8-week design sprints before a line of code gets written. We move fast without cutting corners — here's exactly how.

01

Scoping call — 30 minutes

You explain what you're building. We ask the hard questions — data model, scale assumptions, compliance requirements. No slides, no sales theatre. By the end we both know if we're the right fit.

Free · No commitment
02

Fixed-price proposal — 48 hours

Scope, timeline, and price — in writing, within two business days. No hourly billing surprises. If the project isn't a fit, we tell you why and point you somewhere that is.

Fixed price · Fixed timeline
03

Architecture & design sprint

Data model, system architecture, API contracts, and UI wireframes — all locked before the first sprint. The engineer who scoped your project is the one who ships it.

Senior engineers only
04

Build — sprint by sprint

Fortnightly demos. Working software, not slide decks. You see real progress every two weeks. Scope changes are negotiated honestly, not hidden in a change-order invoice.

Agile · Transparent
05

QA, security audit & deploy

End-to-end test suite. OWASP security checks. Load testing at your expected traffic ceiling. Zero-downtime deploy to your cloud environment. You own the code — always.

Production-grade
06

Post-launch & maintenance

Monitoring, alerting, bug fixes, and feature iterations. Most clients stay with us long after the MVP — because the system is built to grow, not to be replaced.

Ongoing support available
WHY TEAMSEVEN

We're not the only agency.
Here's what's different.

Senior engineers. Not juniors supervised by seniors.

Every project is led by an engineer with 5+ years of production SaaS experience. The person who scopes your project ships it. No handoff halfway through to someone who doesn't know your system.

Senior engineers only · 5+ yr average

600 projects in. Your problem isn't new to us.

Logistics SaaS, healthcare platforms, PropTech, EdTech, AI tooling — we've built the shape of your problem before. That cuts scoping time in half and means we know where things go wrong at week 8.

600+ shipped · 99% on-time · 5.0 rating

Your timezone. Your contracts. Your compliance.

US EST/PST, UK GMT, AU AEST. USD/GBP/AUD invoicing. GDPR, HIPAA, and Australian Privacy Act built in from day one — not bolted on after a compliance audit finds the gap.

Active clients in US · UK · AU

You own the code. Full stop.

No vendor lock-in. No platform dependency. You get the full source, the database schema, the deploy pipelines. If you ever want to take it somewhere else, everything you need is yours.

Zero vendor lock-in · Code ownership guaranteed
FAQ

Questions we get asked before every project.

Do you work with early-stage startups or only established businesses?

Both — but we're best suited to founders who have validated the problem and need production-grade software. Fixed-price MVPs start from $35k. If your budget is under $15k, we're probably not the right fit yet.

What tech stack do you use?

We pick the stack that fits the problem. For most SaaS platforms: Angular or React on the front, Node.js or .NET on the back, PostgreSQL or MySQL for the database, AWS or Azure for infrastructure. We don't have a preferred stack — we have the right one for your project.

How do you handle compliance — GDPR, HIPAA, etc.?

We build it in from day one, not as an afterthought. We've shipped HIPAA-compliant platforms for US healthcare clients and GDPR-compliant platforms for UK and EU clients. If compliance is part of your requirements, it's part of the architecture from the first design session.

Do you offer ongoing maintenance after launch?

Yes. Most of our clients stay with us for ongoing development, bug fixes, and feature work after launch. We offer retainer-based maintenance packages. You're not left with a codebase and no one to call.

Are you a Node.js / Angular / React Native development company?

Yes to all three. Node.js is our primary backend — our engineers average 5+ years of production experience with it. Angular is our primary frontend framework for web apps. For mobile, we primarily use Ionic for cross-platform and native Swift/Kotlin when platform-specific performance is required.

Who actually works on my project?

Senior engineers — not juniors supervised by a senior who's stretched across 12 projects. The engineer who scopes your project leads the build. We're a lean team by design. You get direct access to the people doing the work, not a project manager relaying messages.
