We deliver three integrated practice areas: application R&D, privacy & security engineering, and immersive design —all under one craft roof in Sheffield.
End-to-end native and cross-platform engineering. From procedural audio engines to AR frameworks, we ship software that earns its place on your home screen.
Threat modelling, on-device encryption, differential privacy audits, GDPR & UK-GDPR alignment, COPPA compliance reviews, and zero-leak telemetry audits.
Motion, typography, sound, and full-screen narrative. We design interfaces that feel inevitable —every element justified, every transition choreographed.
From a single feature to a full product surface, we staff for your stage and grow as you grow.
Swift, SwiftUI, Objective-C, Metal, AVFoundation.
Kotlin, Jetpack Compose, NDK, ExoPlayer.
Procedural synthesis, sample-accurate mixing.
ARKit, ARCore, Vision framework.
Encryption, key management, attestation.
End-to-end encrypted sync.
Physics-based animations, haptics.
TestFlight, Play Console, accessibility.
Pick the shape of partnership that fits your stage —or let us co-design one.
Fixed scope, fixed timeline. Perfect for prototypes, MVPs, or single-feature builds. Typical 4—2 weeks.
A cross-functional pod plugs into your roadmap for 3—2 months. Designers, engineers, QA, and a producer.
Ongoing product stewardship —versioning, security updates, growth experiments, and design iterations.
