Custom SaaS, CRM & AI Software Built for B2B Operations

When off-the-shelf software stops fitting how you actually operate, we build custom SaaS, CRM, and AI systems for founders and ops teams worldwide. Or we embed our senior engineers directly in your team, the same people who built the platforms 510 UK companies, a national ambulance service, and a US university run on.

TWO WAYS TO WORK WITH US

Which one are you here for?

Commission a finished product, or add senior engineers to the team you already have. Same engineers, two different ways to buy their time.

Project delivery

Hand us the build

Fixed-price SaaS, CRM and platform delivery. We own the outcome, you get a finished product, live in production. Scoped to your build.

Staff augmentation

Extend your team

Add our senior engineers to your existing team. You keep the roadmap and the code; we carry employment, payroll and HR. Monthly, scale up or down.

AI TECHNOLOGY PARTNER

AI that ships to production, not a pilot that stalls.

Most teams get an AI proof of concept that never leaves the demo. We wire LLMs, RAG, and agentic workflows into platforms that already carry real load, because we built the platform too. The same senior engineers, now building with AI in the stack from day one.

AI-native engineers, not a separate "AI team"

Every senior engineer here builds with LLMs, evals, and agent frameworks as default tools. There is no handoff between the app team and the AI team, and no scheduling an AI specialist in for a sprint. It is how the whole team already works.

Prompt versioning · eval suites · guardrails

We own the whole stack

AI plugged into a system we architected behaves. AI bolted onto someone else's black box does not. We design the data model, the APIs, and the event streams so AI features go in as a feature ticket, not a rewrite.

Data model · APIs · retrieval · deploy

Production, not pilots

RAG over your real data, agents that touch real workflows, cost and latency tuned for production, guardrails and evals from day one. Built the same way we built our own products, Tully AI and Mebag.

Every platform built
from scratch.

Not a template. Not a fork. Every system we ship, from the data model to the deploy pipeline, is written for one client, one problem. That's why our platforms survive scale instead of buckling under it.

YOUR VISION, ENGINEERED FOR REALITY

Most software makes you bend.
We do the opposite.

A healthcare founder in New York. A logistics company in Manchester. A PropTech team in Sydney. An EdTech team in London. Eight years in, we keep hearing the same problem: different words, identical frustration.

Their software was built for someone else's business. So they change how they operate to fit the tool. Manual workarounds. Processes designed around limitations. Teams frustrated by systems that were never designed for them.

That's what we undo. Custom SaaS, custom CRM, enterprise platforms: built around how your business actually runs, not the other way around.

WHY TEAMSEVEN

Six reasons clients stop looking after us.

AI-native engineers, not a bolt-on AI department

Every engineer here builds with LLMs, agents, RAG, and eval pipelines as standard tools. You are not paying for an "AI specialist" to be scheduled in. It is how the whole team already works, and has since GPT-4-class models shipped.

OpenAI · Anthropic · AWS · Azure

600+ projects. Your problem probably isn't new to us.

Logistics SaaS, healthcare platforms, PropTech, EdTech, AI tooling. We've built your problem-shape before, or close enough that we move fast from day one.

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

Your vision drives the build. Not a template.

No copy-paste architecture. No generic sprint ceremonies nobody asked for. We scope around your actual workflow, then build around it. Not the other way around.

Custom scoping on every project

Your timezone. Your contracts. Your compliance.

US EST/PST, UK GMT, EU CET, AU AEST. USD/GBP/EUR/AUD invoicing. Data handling built to each client's regulatory requirements from day one. Three continents, no friction.

Active clients in US · UK · EU · AU

We push through. We don't hand off and disappear.

Hard migrations, tangled legacy systems, compliance that showed up mid-build: we've navigated all of it. The person who scopes your project is the person who ships it.

Senior engineers only · 5+ yr avg.

Built to grow. Not built to be replaced.

Multi-tenant from day one. Zero vendor lock-in. We architect for the business you're becoming, not just the one you are today. When you hit scale, the system holds.

WHAT WE BUILD

From idea to infrastructure.

Custom SaaS and CRM are our core, and we're an AI technology partner on every one of them. Everything else, from mobile to security, APIs, and the integrations that make it all talk, 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.

Enterprise Software

Internal platforms, custom ERP, process automation: built for organisations where off-the-shelf hits its ceiling fast.

Learn more

Web Applications

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

Learn more

Mobile Apps

Native iOS, native Android, or cross-platform via React Native / Flutter, connected to your SaaS backend, not a disconnected standalone.

Learn more

API Development

REST, GraphQL, webhooks, third-party integrations. Secure, versioned, documented. The glue that makes your systems talk.

Learn more

Security & Compliance

OWASP Top 10 practices, auth architecture, and encryption built in from day one, not bolted on after launch. Data handling built to each client's regulatory requirements.

Learn more

Legacy Modernization

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

Learn more

AI Agent Development

Agents that take real actions, not just chat. Multi-step planning, tool use, guardrails, and evals, wired into your systems with human-in-the-loop where it matters.

Learn more

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.

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.

Learn more

DevOps & Cloud Infrastructure

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

Learn more

QA & Test Automation

End-to-end test suites, regression automation, load testing. We write tests that catch what you can't catch manually. Releases don't become incidents.

Design-led development

UI / UX Design

We design the interface before we build it. Wireframes, interactive prototypes, design systems. Then we hand the same team the Figma and they ship it. No handoff gap, no fidelity loss, no "it looked different in the mockup."

Here's what they actually said.

What I love about Team7 is that they always say: No worries, we can find a solution. This is the mindset of builders, creators, people who do not have fear, the partner you need if you want to excel.

Alfonso G.
Founder, Mebag · 🇮🇹 Italy

Working with Mo and his team over the past year has been nothing short of exceptional. I was admittedly sceptical about investing such a large amount, but results exceeded every expectation.

Robert Sinclair

Their responsiveness and willingness to take on our challenging task were impressive.

ABOUT TEAMSEVEN

Eight years ago there were seven of us. Reality narrowed it to two.

September 6, 2017. Seven friends. One shared bet that remote-first engineering would win before it became a LinkedIn trend.

It did. The team got smaller. The ambition didn't. Today we're a lean remote team across four time zones, shipping SaaS and CRMs for founders who can't afford to ship the wrong thing twice.
