Mobile apps, AI features and backend systems — from idea to production.

One studio, full delivery: from first design to the App Store and Google Play.

20+ years of mobile architectureMultiple apps shipped to the storesAgentic AI in productionProducts with millions of users

Four things we do exceptionally well.

Mobile apps

iOS, Android and web from a single Flutter codebase. Native platform depth when you need it.

AI in applications

GenAI features and agents, all the way to production use. Speech, images and text into structured data; assistants that see a task through.

Backends & full systems

An app is only half the system. We also build the services, integrations and cloud infrastructure behind it. One supplier, one responsibility.

Architecture & consulting

Senior-level design and technical assessment: architecture for new systems, reviews and takeovers of existing ones.

Selected work — from idea to the stores.

In production

Peztime

Client delivery — BestPetBook Oy

A platform for pets and their owners: social feed, lost-pet map, calendar and offers. iOS, Android and web from one codebase. Full delivery, project management included.

Use cases

Examples of the solutions we build — with AI and without. If one of these matches a need of yours, it's a good place to start the conversation.

From the field to a report. A worker dictates and takes photos on site — the system writes a structured report straight into your systems. Inspections, maintenance, damage claims.
An assistant that acts. An in-app agent that takes a booking or an order all the way through.
Images into data. Condition assessments, inventories and meter readings extracted straight from photos.
An offline-first field app. Works in dead zones, syncs itself when the connection returns.
A consumer product in the stores. From idea to the App Store and Google Play — like Triplium and Peztime.
An AI feature in your existing app. Your current app gains a new capability — everything else stays as it is.
App takeover. Previous vendor out of the picture? We review, stabilise and keep it moving.

The same team from idea to production, start to finish.

We agree up front what's yours — source, environments and store accounts in your name when you want them.

Note
Proven in production.

Our own products are in the stores. We only sell what we've taken to production ourselves.

Note
Based in Finland, operating globally.

Finnish engineering culture — straight talk, kept promises, software that works.

Pricing without the layers

  • You pay directly for senior work — without a sales organisation, middle layers or juniors on your invoice.
  • We build AI — and we build with AI. Our AI-assisted process means the same experienced people deliver more.
