We design and build custom web + mobile applications and internal tools that automate processes, and help your business scale.
End-to-End Delivery
One senior engineer and one professional designer, amplified by Claude Code. We take your product from first sketch to production — then keep it growing after launch with automated QA, the Google ecosystem, and data-driven iteration.
Product & UX Design
A professional designer shapes the research, journeys and polished UI — so what we build is clear, usable and worth building.
Engineering with Claude Code
A senior engineer pairs with Claude Code to ship production-grade features at AI speed — every line reviewed and owned by a human.
End-to-End Delivery
Discovery, design, build, deploy — one accountable team from kick-off to release. No hand-offs, nothing lost in translation.
Automated QA
Automated test suites and checks run on every change, keeping releases fast, stable and regression-free long after launch.
Growth Hacking, Post-Launch
Once you are live — or if you already are — we drive growth with SEO, funnels and experiments across Google Search, Ads and Analytics.
Data-Driven Improvements
GA4 and Search Console signals feed a continuous loop: measure real usage, learn, and ship the next improvement.
How we work with you.
No 12-week discovery phases. No disappearing acts. A clear, repeatable engagement that keeps you informed at every step.
Discovery
We learn your business, users, and goals in a structured session. No vague briefs — we ask the right questions so scope is clear before anything begins.
Design
UX flows, wireframes, and a polished design system before a single line of code is written. You approve before we build.
Build
Iterative development with weekly demos. You see real working software every week, not status reports. Feedback is actioned the same sprint.
Launch
Full deployment, CI/CD pipeline, and complete documentation. Your team takes ownership of a codebase they can actually work with.
Support
Retainer arrangements available for teams who want continued engineering, feature development, or a technical partner on call. We don’t disappear at launch.
Built by Syntaxa. Trusted by clients.
Calibra
An automation tool that simplifies organisation actions, streamlines calibration workflows, and helps teams manage performance with precision — reducing manual effort and human error at scale.

Syntaxa took our half-finished MVP and turned it into something we were genuinely proud to demo to investors. They didn’t just execute — they pushed back when we were wrong and shipped a better product than the one we had planned.
We’d worked with two agencies before Syntaxa — both technically competent, both low-converting. Within eight weeks of the redesign our trial-to-paid rate went up 31%. The UX thinking was the difference, not the code.
What sets them apart is that they work like a great in-house team would — they push back, ask the right questions, and treat your product as if it’s their own. We’ve been working with Syntaxa for over a year for a reason.
Everything you need to know.
Project cost depends on scope, complexity, and timeline. A production-ready MVP typically ranges from $15,000 to $60,000. A full SaaS product with admin panels, payments, and multi-user roles can range from $60,000 to $200,000+. We provide honest, itemised estimates after a structured discovery session — no ballpark figures designed to win the pitch and inflate later.
Most projects follow consistent phasing: 1–2 weeks of discovery, 2–4 weeks of design, and 6–16 weeks of build depending on scope. A focused MVP can ship in 8–10 weeks from kick-off. We don’t pad timelines — but we also don’t promise dates we can’t deliver.
Yes. We build cross-platform mobile applications using Flutter (iOS and Android from a single codebase) where it fits the project. We also build responsive web applications that work excellently on mobile. Most of our engagements include both a web and mobile experience.
Delivery includes full handover documentation, a working CI/CD pipeline, and a codebase your own team or next agency can maintain. We offer ongoing retainer arrangements for teams that want continued engineering support or a technical partner on call. We don’t disappear at launch.
Yes, and we’re good at it. Inheriting a codebase is a different skill from greenfield development — it requires reading unfamiliar code, identifying technical debt, and making decisions that work with the existing architecture. We do a technical audit before committing to any scope so there are no surprises. See our guide on closing the MVP gap.
Both. We work with pre-seed founders building their first product, Series A companies rebuilding something that outgrew its original architecture, and internal teams at established businesses who need specialist capacity. The right engagement structure looks different at each stage and we’ll tell you honestly which fits.
We use weekly demo calls, a shared project board, and async updates between check-ins. You always know what was built this week, what’s coming next, and what decisions are pending. We manage contracts and payments through Contra — commission-free with secure escrow so you’re protected throughout.
Our primary stack is Next.js (App Router), TypeScript, React, Tailwind CSS, Supabase, and Vercel for web — and Flutter for mobile. We also work extensively with Claude Code and AI-assisted development tooling. We choose what’s right for the project, not what we’re most comfortable with.
