Mobile apps
iOS and Android. Native where it matters, cross‑platform where it saves money.
Software studio from New York. Since 2001.
Apps that ship.
Systems that last.
We design and build mobile apps, web platforms and AI features. Then we keep them running.
We build software that businesses run on. Today that means mobile apps, web platforms and applied AI, designed, shipped and maintained by one team.
What we build.
Web platforms
Customer portals, admin panels and dashboards.
AI and machine learning
Forecasting, computer vision and language models, built into the product.
Cloud and DevOps
Kubernetes, CI/CD and monitoring, so releases are routine.
Integrations
Payments, CRMs and ERPs connected through one API.
From first sketch
to the App Store.
Discover
We work out what the product has to do, what it can skip, and what it will cost.
Design
Clickable prototypes you can put in front of real users before any code is written.
Build
Regular builds on your own phone, so progress is something you can tap.
Run
Monitoring, fixes and updates for each new iOS and Android release.
Three ways to work with us.

A defined product with an agreed scope, timeline and price. Best for a new app or an MVP.
Fixed priceTeam
Designers and engineers who join your roadmap and work inside your process and tools.
MonthlyCare
