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.

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.

Enterprise Software

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

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 & Secure Architecture

OWASP Top 10 practices, encryption, and secure architecture reviews. We audit and harden SaaS platforms before a breach finds what you missed.

DevOps & Cloud

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

Learn more

CRM Development

Custom CRM built around your pipeline, not a generic template. Your data model, your workflow, your sales process. Fixed-price, scoped to your build.

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, and visual design: everything that sits between your users and the backend doing all the work.

Learn more

IT Staff Augmentation

Hire dedicated developers who embed in your team. Vetted senior engineers across Angular, React, Node.js, .NET, and Flutter, working overlapping US, UK, and AU hours. You keep the roadmap and the code.

Hire developers

AI Agent Development

Agents that take real actions, not just chat: multi-step planning, tool use, guardrails, evals, and human-in-the-loop. Built by engineers who ship AI to production.

MVP Development

The smallest production version that tests your idea, built by senior engineers on architecture that scales. Fixed price, 8 to 16 weeks, then a build-on retainer.

Scope an MVP

Data Engineering & Analytics

ETL pipelines, reporting databases, warehouses, and dashboards your team actually uses. A clean data layer that AI features can sit on without a nightly export.

Learn more

Systems Integration

Connect your ERP, CRM, accounting, and industry platforms so data moves automatically: point-to-point, middleware, and APIs for the systems that lack them, with monitoring built in.

Learn more

Legacy Modernization

Update business-critical systems without stopping the business: cloud migration, re-platforming, and incremental rebuilds behind a stable interface. Phased and fixed-price.

Learn more

Software Project Rescue

Take over a stalled, over-budget, or abandoned build. A paid audit first, an honest assessment of what is salvageable, then fixed-price phased recovery.

Book an audit

Product Design Sprint

One idea or one broken flow, taken to a validated, designed solution in two to three weeks. Fixed scope, fixed price, a clickable prototype and a recommendation.

Dedicated Development Team

A self-contained pod of a lead, senior engineers, design, and QA that owns your product or workstream end to end. Predictable monthly rate, AI-native engineers.

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 on data model, scale assumptions, and 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+ projects · 5.0 rating

Your timezone. Your contracts. Your compliance.

US EST/PST, UK GMT, AU AEST. USD/GBP/AUD invoicing. Data handling built around GDPR, HIPAA, and Australian Privacy Act principles from day one, not bolted on after the fact.

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, scoped after a call. If your budget is below a certain threshold, we're probably not the right fit yet, and we'll tell you that upfront.

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 data handling in from day one, not as an afterthought. We've built platforms for US healthcare clients and UK and EU clients around their required data-protection guidelines: access control, audit logging, encryption, and data residency. We're not a certification body, so we don't issue HIPAA or GDPR certifications ourselves; if your project needs a formal audit, that's a separate engagement with a specialist firm.

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 and Angular is our primary frontend framework for web apps, both with years of production use behind them. For mobile, we build with React Native 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.
