For companies building connected devices

Connected product development for hardware companies.

We build and stabilize the software layer of connected products: mobile app, BLE and Wi-Fi connectivity, backend and cloud: so a working prototype becomes a reliable product, not a permanent demo.

One connected system
Your device
Mobile app
Cloud
Device, app, backend and cloud: one architecture, one responsibility. We work across the boundaries, not on isolated app screens.
Who this service is for

Your hardware works. Your software is the risk.

Teams usually reach us in one of these situations:

The hardware is solid, but the software is not production-ready.
Demos go fine: devices in the field drop, desync, or never reconnect.
App, firmware, backend and cloud were built separately, and behave like it.
Support tickets are mostly connectivity and sync: not hardware.
The prototype architecture no longer carries the production requirements.
Your engineering team is strong on hardware: connected-product software isn't its core.
Business
Connected products usually fail because of early decisions, not poor programming. One architecture decision can cost six months.
What the service includes

Everything between your hardware and your customer.

Architecture

Product & software architecture

One architecture across the firmware boundary, mobile app, backend and cloud: designed for versioning, failure and growth, not just the happy path.
Mobile

Android app development

Native Android engineering: Kotlin, Jetpack Compose, background processing, local persistence: apps that make complex hardware feel simple.
Connectivity

BLE & Wi-Fi integration

Device discovery, pairing, Wi-Fi provisioning, reconnection and protocol integration with your firmware: the layer where most connected products break.
Cloud

Backend & cloud

Accounts, device data, synchronization and REST APIs: we build the platform end to end in your cloud account as part of the connected-product software system.
Reliability

Reliability engineering

Offline behavior, error recovery, device state management, logging and diagnostics: the invisible work that decides how the product feels.
Production

Production readiness

Testing with real hardware under real failure conditions, launch preparation, and long-term maintenance once the product is in the field.
Connected-product architecture

One product. Four boundaries. That's where it breaks.

Every connected product crosses the same boundaries: device to app, app to backend, backend to cloud. Each one is a place where state can diverge, and where a demo quietly differs from a product.

What ships from the prototype phase

These nine failure points sit between the systems, not inside them. That's why we take responsibility across the boundaries.

Problems we help solve

Technical condition → business consequence.

Unstable connections in the field

Every dropped connection becomes a confused user, then a support ticket, then a review. Reliability work pays for itself in support cost.

Inconsistent device, app and cloud state

When three systems disagree about the truth, users stop trusting all of them. Sync architecture decides which product you actually ship.

Prototype architecture at its limit

Code written to prove feasibility rarely carries scale, versioning and recovery. Caught early, that's a plan: caught late, a rewrite.

Difficult onboarding & provisioning

The first ten minutes with the product decide returns and ratings. Pairing and Wi-Fi setup deserve engineering, not hope.

Firmware / app version drift

Fielded devices run old firmware forever. Compatibility has to be designed: otherwise every release risks breaking someone's device.

Launch dates slipping on software

Hardware is ready; software keeps finding new edge cases. Naming risks early converts surprises into a schedule.

How we work

Assessment before architecture. Architecture before code.

01 / Understand

Product & architecture assessment

Hardware, firmware protocol, app, backend and cloud reviewed as one system: where it stands today, what production will demand of it.
02 / Plan

Risks & dependencies, named

Each technical risk tied to its business consequence: delay, rewrite, support cost, and sequenced into a plan you can defend internally.
03 / Design

Architecture for the whole chain

Connectivity behavior, sync strategy, device state, upgrade paths: decided deliberately, documented, and agreed before implementation.
04 / Build

Incremental development & integration

Working software against real hardware from early on. Integration boundaries are exercised continuously, not at the end.
05 / Launch

Failure testing & production preparation

Testing under real conditions: weak signal, dead batteries, interrupted updates. Then diagnostics, monitoring and release.
06 / Grow

Operation & evolution

Launching isn't the finish line: field feedback, maintenance, new capabilities: with an architecture that was built to absorb them.
From prototype to production

A demo proves the happy path once. Production is every path, every day.

The distance between a working prototype and a reliable product is a defined set of engineering topics: none of them visible in a demo. We make them explicit, then work through them deliberately.

Risk
Most connected products don't fail at launch. They fail quietly afterwards: in reviews, support queues and churn: because production topics were skipped, not unknown.

Frequently asked questions

Honest answers to the usual questions.

Do you develop the complete product or only the mobile application?

We take responsibility for the software layer: mobile app, connectivity, backend and cloud integration, and the architecture that connects them. Hardware and firmware stay with your team: we integrate closely with both.

Can you work with our existing firmware?

Yes. We integrate against your existing protocol and communication layer. Where the protocol itself blocks reliability, we specify the changes precisely so your firmware team can implement them.

Can you improve an existing connected-device app?

Yes. Most engagements start from existing software. An architecture review comes first, so improvements target the actual causes: not the symptoms.

Can you help move a prototype into production?

That transition is the core of this service. We assess what the prototype proves and what production additionally requires: then close the gap in planned, testable increments.

Do you work with internal engineering teams?

Yes: partnership rather than outsourcing. We work alongside your hardware, firmware and product people, and make the reasoning behind every architecture decision explicit.

Can we start with a review before committing to development?

Yes. The Connected Product Blueprint is a one-week planning engagement: architecture review, risk identification and a sequenced set of recommendations : useful on its own, whoever builds afterwards.

Next step

Discuss the software architecture behind your connected product.

Share your product stage, hardware platform, connectivity setup and main technical challenge. We'll tell you honestly whether an architecture review, a focused integration project, or a broader engagement fits, or whether we're not the right partner.
