STX Next

STX Next is a software development company headquartered in Poznań, Poland. It was founded in 2005 by Maciej Dziergwa, Peter Valkenburg and Andrzej Mleczko as the Polish branch of a Dutch company, and it describes itself as a Python-native team with more than 20 years of engineering behind it.

Today the company presents itself as an AI transformation partner for industrial and financial organisations, aiming to turn isolated AI experiments into systems that run in production. It has delivery centres in Poznań and in Mérida, Mexico, and offices in London, Eschborn near Frankfurt and the Houston area in Texas.

Key features

• AI and automation. AI development, machine learning, enterprise retrieval-augmented generation, document processing with OCR, AI training workshops, and builds on Amazon Bedrock, Microsoft Copilot Studio and n8n.
• Data engineering. Data platforms, lakehouses and visualisation on Snowflake, Databricks, Apache Iceberg and Microsoft Fabric.
• Cloud. Cloud strategy, migration to AWS and Azure, and sovereign cloud options for European data requirements.
• Software development. Python development, web applications, AI-assisted software delivery, mobile apps and quality assurance.
• Design. Product design, dashboard design, and concept design with prototyping.
• Three engagement models. Consulting with subject-matter experts, end-to-end development from discovery to deployment, and team extension, which the company says can add developers within 14 days.
• Certifications and partnerships. ISO 27001 (2024), a TISAX assessment (2025), AWS Advanced Tier partner status and the Select tier of the Claude Partner Network services track, according to its own pages.

Who it is for

STX Next suits mid-sized and large organisations, especially in manufacturing, industry and financial services, that need Python, data or AI engineering and want a partner able to work under security and compliance requirements. Start-ups and product companies can also use it for end-to-end builds or to extend an existing team. Buyers who need only front-end or marketing work may find a design studio a closer fit.

Pricing at a glance

STX Next does not publish rates or minimum engagement sizes. It offers a free initial consultation, after which work is scoped and quoted for consulting, end-to-end development or team extension. Prices as checked on 10 October 2026; confirm on the vendor's pricing page.

Things to consider

• Python and data centre of gravity. The strongest depth is in Python, data and AI; check experience if your stack is mainly another language.
• Sector focus. Recent positioning targets industrial and financial clients; ask for relevant examples if you work elsewhere.
• Time zones. Delivery runs from Central Europe and Mexico; agree overlap hours for teams in Asia or the Pacific.
• Choose the model deliberately. Team extension leaves product ownership with you, while end-to-end delivery shifts more responsibility to STX Next.
