Software built by people who break software.
Web, mobile and SaaS products from the team that also runs our penetration tests. Security is designed in from day one, so you ship fast without shipping risk.

From first prototype to platforms with millions of users.
One team across design, engineering and security. No hand-offs between agencies.
Web applications and SaaS platforms
Multi-tenant platforms, customer portals and MVPs, built to scale and to pass a security review on day one.
iOS and Android apps
Native apps with biometric login, offline support and secure storage.
Cross-platform apps
One codebase for iOS and Android with React Native or Flutter.
Internal tools and dashboards
Replace spreadsheets with tools your team actually wants to use.
APIs and integrations
Connect your systems, partners and payment providers reliably.
Amazon SP-API apps
Seller tools built to pass Amazon’s data protection review.
AI features
LLM-powered search, assistants and automation, with guardrails.
UI and UX design
Research, prototypes and design systems before a line of code.
Maintenance and support
Updates, patches and monitoring for products already live.
Our testers review the code before your customers use it.
Most agencies bolt security on at the end. We run a check at every stage of every sprint.
Working software every two weeks.
You see progress in a live environment from the first sprint, not a big reveal at the end.
- 01
Discovery
Goals, users, constraints and risks. We recommend a stack and a delivery plan.
- 02
Design and prototype
Clickable prototypes tested with real users before build begins.
- 03
Build in sprints
Two-week sprints with a demo and a working release at the end of each.
- 04
Security sign-off
A full penetration test by our own testers before launch, with a report you can share.
- 05
Launch and grow
Go-live support, monitoring and a roadmap for what comes next.
Pick the model that fits your stage.
Fixed-scope project
Agreed scope, timeline and price. You know exactly what you’re getting and when.
Discuss a projectDedicated team
Most chosenA senior team working as part of yours: engineers, designer and a security lead, scaled as you grow.
Build a teamSupport and maintenance
Monthly hours for fixes, updates, dependency patches and security monitoring, with agreed response times.
Talk about supportBefore you ask.
Which technology will you use?
Whatever suits your product, team and budget. We’ll recommend a stack in discovery and explain why. If you already have one, we work with it.
Can you take over an existing codebase?
Yes. We start with a code and security review, then give you a clear plan for stabilising and improving what you have.
Who owns the code?
You do. All code, designs and documentation transfer to you, and we work in your repositories from day one if you prefer.
How do you keep costs predictable?
Fixed-scope projects have a fixed price. Dedicated teams have a fixed monthly cost. You get a sprint-by-sprint view of progress either way.
Does security slow delivery down?
No. Checks run inside each sprint rather than at the end, so issues are cheap to fix and launches don’t slip.
Do you sign NDAs?
Always. We’re happy to sign yours before the discovery call.
Tell us what you’re building.
A 30-minute discovery call with a senior engineer. You’ll leave with a recommended approach, stack and rough timeline.
