Why Avantra
An independent practice that works the way a senior team should.
01
Senior, hands-on
Direct access to the people building your software. No account managers, no junior handoffs, no telephone game.
02
Built to be handed over
Documented, tested, and structured so your team can own and extend the software long after the engagement ends.
03
Honest about scope
If a project doesn't need building, we'll say so. If it needs reducing to land safely, we'll say that too.
Process
A clear path from idea to live software.
Predictable phases, weekly demos, no surprises. You always know what's happening and what's next.

Marquee practice · Mobile
Mobile apps people actually keep on their home screen.
From a first TestFlight build to a flagship App Store launch - native iOS, Android, and Flutter, built with the polish your users expect from the apps they already love.
- iOS in Swift / SwiftUI, Android in Kotlin, cross-platform in Flutter
- Offline-first sync, push, payments, deep linking, accessibility
- App Store, TestFlight, Play Store delivery, including review escalations
- Performance budgets and crash-free targets baked into the build

Specialty · AI Automation
Stop doing the work a well-built agent could do.
Quiet, reliable automations that sit between your tools and do the repetitive operational work - triage, routing, summarising, drafting, reconciling - so your team can focus on the parts that need a human.
- AI agents wired into email, CRM, docs, calendars, and internal APIs
- Workflow automation across n8n, Zapier, and custom code where it matters
- Document understanding: extraction, classification, drafting
- Hosted, monitored, and handed over with a clear cost-per-run model

About Avantra
Built by people who have shipped this before.
"Most software projects don't fail because the technology is hard. They fail because the wrong thing got built. Our work starts with making sure that doesn't happen to you."
Avantra Services is an independent software consultancy based in the UK, working with small businesses, startups, and founders who need senior engineering judgement in the room. Production experience across mobile, web, backend, and AI - with the discipline of a team that owns what it builds long after launch.
