300DEVS

300DEVS is a Polish software house founded in 2015, based in Lublin with a team of about 30 developers. The company focuses on building custom software for construction, infrastructure, and e-commerce businesses, with particular expertise in digitizing operations like timekeeping, fleet management, and cost control. They've completed over 100 projects for roughly 80 clients across Europe and beyond.

Services and capabilities

300DEVS offers a range of development and consulting services. On the product side, they handle MVP development, custom software tailored to business needs, e-commerce platforms for both B2B and B2C, and landing page design. They also provide API design and integration work, connecting external systems with existing applications to enable data exchange and improve scalability.

Consulting services include product discovery workshops (helping teams explore user needs and business requirements), process mapping (diagramming and analyzing workflows to identify inefficiencies), IT and AI consulting, and software audits. Their support model includes ongoing software care and maintenance—technical support, bug fixes, updates, and optimization for existing systems—plus body leasing arrangements where clients can hire experienced developers for fixed periods.

Notable work

The source mentions several named projects: Clothr (a virtual fitting room tool that suggests correct sizing), Darex (an e-commerce platform for B2B customers), Navimed (an in-building navigation application), and TST (a container rental management system with route optimization). For VOSTI, they built a heat pump calculator described as "the first engineer-friendly tool on the market" for estimating building energy and heat costs. Beyond these, they list clients including Delante, Vilaro, 4IDEA, AssetLife, POL-MAK S.A., Elmax, TEZET, and Fundacja VCC—all of whom provided testimonials.

How they work

300DEVS positions itself around collaboration and direct client involvement. They maintain offices in Poland and are accessible via UK, US, and Australian phone numbers, suggesting they work with distributed teams across time zones. The company emphasizes workshop-based discovery and iterative feedback loops, particularly for MVP work. No explicit pricing model is stated in the source.
