Amsterdam Standard

Amsterdam Standard is a nearshore software development firm based in Poland with offices across Europe. Founded over 14 years ago, the company operates 120+ engineers across five locations in Poland and the Netherlands. Leopold van Oosten leads as CEO, with Tomasz Rżany as co-founder and head of AI. The firm positions itself as a technology partner for climate tech innovators and SaaS startups, offering team extension, custom development, and AI-assisted refactoring services. Their stated focus is reducing technical debt and adding AI capabilities to products—claims they back with a case study showing "63% faster" delivery and "60% performance boost using AI-assisted coding."

Services and capabilities

Amsterdam Standard organizes its work into four suites. The Team Extension Suite adds engineers directly into client teams across React, Vue, .NET, PHP, and Python. They claim 6+ years average partnership length and emphasize European time zones with fluent English. Core services focus on refactoring legacy code (marketed as "50% faster") and reducing technical debt. Forge handles custom AI solutions and expanding AI capabilities into existing products, using LangChain and n8n. Studio offers AI consultations, workshops, and hackathons for developers.

Beyond code, they provide technical audits, cybersecurity and infrastructure scans, DevOps support, cloud architecture work on AWS/GCP/Azure, UX/UI design, and project management training. They also run PoC workshops, 360° business reviews, and "process optimizations."

Their engagement flow follows three stages: discovery and experimentation (initial game plan), build and iterate (reduce tech debt, ship features), then deliver and grow. They promise a free Technical Quick Scan within 2 weeks of an introductory call, followed by a Tailored Growth Plan within 7 days.

Notable work

Amsterdam Standard lists 40+ active clients and highlights partnerships with climate tech companies. Named clients include Salacia Solutions (ESG reporting), Channel Engine (marketplace connectivity), Esdec (solar mounting systems), MrWork (AI for recruitment), 2Solar (solar operations software), Pré Sustainability (science-based sustainability), GoPhoto (photography platform software), DeWarmte (heat pump solutions), Zonhub (sustainable energy investment), Vandebron (green energy), FarmTree (agroforestry projections), and Big Mile (carbon analytics).

Testimonials come from Cyril Mallet (CTO, Platform161, working since 2017), Dirk Meeuws (COO/CTO, OnRecruit), Jeroen van Der Heide (Director, Zanders), Steven le Corvaisier (Software Team Lead, PRé), and Daniel Duivestein (CEO, GoPhoto—8 year partnership). Most emphasize ease of integration with existing teams and ability to handle rapid scaling. Mallet specifically notes that communication "easily integrates" despite remote work; Duivestein calls them "the key-to-success" for his business.

How they work

Amsterdam Standard operates on a nearshore model, placing engineers in Poland within 6 weeks. They bill via dedicated teams or time-and-materials arrangements (not explicitly stated but implied). Team members operate in European time zones and integrate into clients' existing workflows, tools, and project management. The Partnerships Manager role and references to "growth planning" suggest they act as account leads, not just resource vendors. They emphasize no hiring overhead and rapid scaling up or down. Their Sustainable Scaling System is their branded methodology—though the details remain largely abstract marketing language in the source material.

Team and credentials

Co-founder and CEO Leopold van Oosten and co-founder Tomasz Rżany (head of AI) lead the operation. Kate Rżany serves as CFO/COO; Radek Fąfara is Chief Sourcing Officer and head of Wroclaw and Poznań offices. Other named leaders include Karolina Osmęda (Head of PMO), Piotr Miernik (Head of Delivery), and Adam Matysiak (Head of Growth & Sustainability). The company does not list SOC 2, ISO 27001, HIPAA, or other formal compliance certifications in the source material. They do note their goal to be "Net Zero" by 2025 and claim to be "Proud founder of the Climate Tech Summit." The source does not provide Clutch, G2, or other third-party review ratings.

All engineers reportedly have fluent English and "very similar culture" to Western Europe. The company highlights Poland's strong universities and "highest ranking coders," though these are unverified claims typical of nearshore marketing.
