300.codes

Software for marketing and sales goals, built in Poland

A Polish software house that calls itself a software boutique, 300.codes builds web and mobile products for people who have marketing and sales targets to meet. Its parent group also includes the marketing agency KERRIS, and the group cites more than thirteen years of market experience. That pairing lets it combine development with communication strategy, creative concepts and performance campaigns, so the people designing an interface have usually worked on the marketing side too.

What it builds

The company's range covers e-commerce web applications, mobile apps, interface design for web and mobile, websites and custom software. Examples it presents include a platform that joins a pharmacy and a drugstore in one scalable online sales system, a modernised online pharmacy, a gamified e-learning platform for doctors, and a mobile game with a receipt competition used to lift ice cream sales. It also names a soil carbon absorption estimating tool, mobile-first e-commerce design, and maintenance for a personalised gifting business among its earlier work. For hybrid mobile apps it uses NativeScript. Websites are built on WordPress and Webflow, and the firm says its WordPress work puts it among the strongest in Europe.

Understanding the business first

The firm says it verifies what a client's business and customers need before anything is designed, because technology has to meet business goals. It treats code quality as only one part of the job and puts weight on concept work, choosing the right architecture, product design, usability, conversion and communication. Where it lacks the competence for a client's chosen technology, it says it will not force its own stack and will take responsibility for delivery with a partner.

Measured results and compliance

Its stated outcomes include faster page speed, higher engagement, A/B tests of interface decisions, search optimisation for both classic search and generative engines, lower bounce rates and a lower cost of winning a lead. The delivery side covers GDPR compliance, accessibility optimisation to the WCAG standard, a fixed-fee model, and executive summaries that show return on investment to key stakeholders.

How it works with clients

300.codes describes a direct line to the people doing the work, so progress and quality are always visible. It plans for change rather than avoiding it, and says it sets up a working framework to suit each project instead of a standard template. It also says it shows project status, team seniority and level of commitment openly, and calls itself a partner rather than a contractor. Its technology list includes PHP, Vue, React and Python.
