Software house · Warsaw · since 2014
Small teams. Big systems.
We design, build and maintain software: web, mobile, backend, IoT and data. You talk directly to the people who write the code – no sales layer, no subcontractor chain.
- Experienced developers
- The code and repo are yours
- We work in Polish, English and German
Services
What we do
We take a project from idea to production, or join your team. That includes taking over and cleaning up an existing system.
Web applications and systems
Dashboards, portals, internal systems, APIs and integrations. From MVP to multi-role, high-traffic systems.
Mobile apps
iOS and Android, native or cross-platform. Including apps that work with hardware: Bluetooth LE, beacons, sensors.
IoT and automation
Raspberry Pi gateways, Modbus, RS485, wM-Bus, MQTT. Reading meters and inverters, control, remote access without opening ports.
Data and analytics
Time series, reports, ETL, forecasting and optimisation. Device and system data in one place, for ESG reporting and decisions.
Consulting and architecture
Code and infrastructure audits, technology choice, migration plans, security reviews. Concrete recommendations with cost and risk.
Maintenance and development
We take over existing systems, clean them up, document and extend them. Monitoring, updates, fast incident response.
Technology
Technology that fits the problem
We don't have one favourite. We work in the stack you already have, or pick the one that solves the problem most simply and is still maintainable five years from now.

Infrastructure
Your technology isn't listed? Chances are we've worked with it. Ask – we'll tell you straight if we're not the right team.
How we work
Simple and predictable
Conversation
Problem, constraints, budget, deadline. Free and with no commitment.
Plan and quote
Scope, architecture, milestones, cost. You see what you pay for and what you get at each stage.
Iterations
A working build every 1–2 weeks on a staging environment. Repository access from day one.
Launch and maintenance
Production, monitoring, documentation, knowledge transfer. We keep developing it, or hand it over to your team.
Products
Our own products
Besides client projects, we build and run two systems of our own. That's how we know what it costs to keep software running for years.
Energy and utilities in buildingsPolbyte IoT
A platform for reading and analysing electricity, water, heat and gas consumption. A gateway on site, a web dashboard and a mobile app.
- Meters, PV inverters and batteries over Modbus TCP/RTU, SunSpec and wM-Bus radio
- Installed without an integrator and without opening ports on the customer's network
- Energy strategy: PV and consumption forecast, hourly market prices, battery schedule
- The gateway runs the plan itself, even offline
Business management systemPolbyte ERP
Our ERP runs in the browser, and we tailor its modules to the company's processes. Fleet and asset monitoring is built in, not bolted on.
- Business partners, locations, stock, sales, projects
- Service, transport, production, calendar and reports
- Monitoring: GPS trackers, BLE beacons, cameras, zones on the map
- We deploy and extend modules for your specific business
Clients
Who we've worked with
Companies from Poland, Germany, Switzerland and the UK: telematics, mobile advertising, mobility, recruitment, software.
Tracking shipments, cold chains, pallets and fleets. Mobile apps.
lostnfound.com ↗An agency that plans and runs interactive smartphone ad campaigns for brands and publishers.
bam-interactive.de ↗One app to compare and find cars from many car-sharing services in a city.
carjump.me ↗An international firm recruiting IT specialists, engineers and scientists across Europe and the US.
darwinrecruitment.com ↗A Warsaw software house. A partner on client projects when an extra pair of hands or a specific skill is needed.
softwebo.pl ↗The gateway reads an energy meter and wM-Bus radio water meters. Data flows live to the dashboard and the mobile app.
iot.polbyte.com ↗We have also worked with Welldoo and Etendard, among others.
Startups and hackathons
We love startups and hackathons
We do our best work where pace matters: a new product, little time, lots of unknowns. We build the first working version fast, put it in front of real users, and only then extend it.
Six Hackathon, Zurich – 1st place
A working iPhone app prototype in 48 hours. The jury looked at an app on a phone, not at slides.
How it went →MVPs for startups
From idea to first users: the smallest version that works end to end. We know budget and time are limited, so we cut everything that can wait.
Hackathons and events
We travel to hackathons and tech events across Europe. Happy to join your team or help build a prototype for demo day.
Articles
Technical articles
We write about what we've built ourselves: real problems, solutions and code.
When to charge a home battery? Dynamic programming on day-ahead prices
Energy prices change every 15 minutes. How to compute a charge/discharge plan that actually lowers the bill – with PV and consumption forecasts and the cost of battery wear.
Read →Six Hackathon in Zurich: a working iPhone app in 48 hours
From Polbyte's history: our developer was on the team that took first place. What we still apply from that weekend to every prototype.
Read →wM-Bus radio water meters: reading them with a Raspberry Pi and a CC1101
Water, heat and gas meters broadcast their readings on 868 MHz by themselves. With a few euros of hardware you can receive them without a meter reader or the vendor's system.

Most PV inverters, batteries and energy meters speak Modbus. How to read them locally, what SunSpec gives you and where the traps are.
