## About

Dev4You (Poznań, Poland) is a custom software house built around tailored software for distributed energy, IoT, and manufacturing, working with clients across Europe.

## What we do

Custom software development for energy operators, hardware manufacturers, and factories: PV/BESS fleet management platforms, EMS/HEMS energy management systems, IoT device cloud platforms for large-scale data collection, custom ERP/MRP and production planning/optimization systems, warehouse management (WMS), plus product discovery and UI/UX design workshops.

## Our specializations

- Energy management systems and PV/BESS fleet platforms (EMS/HEMS)

- IoT device cloud platforms and large-scale data collection

- Custom ERP/MRP, production planning, and optimization systems

- UI/UX design workshops and product discovery

## Who we work with

Distributed energy operators, utilities, and hardware manufacturers who need a software layer on top of their equipment; and manufacturers who've outgrown off-the-shelf ERP and need something built around how they actually run production. Companies that need custom-built software rather than an off-the-shelf platform.

## Industries we serve

Energy & utilities, manufacturing, logistics (WMS).

## How we work

We start from the business concept, validate it through a PoC, build an MVP, and then grow the system with the client — through active development and long-term partnerships, not one-off delivery. We work hands-on alongside our clients' own teams rather than at arm's length, agreeing on technical decisions together and building up their in-house competence along the way.

50+ completed projects, including relationships that have run 3+ years and counting.

## Software is about to be built completely differently.
