#Grupa Insight | Custom Software
Custom systems built for business
Grupa Insight is a Warsaw-based software development company building custom solutions for businesses whose processes have outgrown off-the-shelf tools. We develop web and mobile applications, headless and composable commerce platforms, B2B portals, and systems integrated with ERP, CRM, payment services and external APIs. We can take a new product from concept to launch, step into an existing system or handle a migration when the current technology begins to limit performance, integrations or further sales growth. We use headless architecture where it creates a genuine business advantage: it allows the frontend to evolve independently, speeds up the delivery of new features, connects multiple sales channels and integrates the storefront with the company’s existing systems. We do not recommend headless by default. We use it when the business goals, scale and integration requirements justify the architecture.
Our technology stack includes Node.js, Next.js, React, PHP, Python, Magento, Shopify, PrestaShop and WooCommerce. We also build AI agents, RAG systems and LLM integrations that work with company data and organisational knowledge. Every project starts with the business case. We select the architecture and technology stack to support the client’s objectives while making efficient use of the available budget.

We design systems from an architecture perspective, not just code. We match technology to your business model, data sources, integrations, SEO requirements, Core Web Vitals and future scalability. This means the solution is not only implemented — it is easy to develop, measure and integrate with future tools.
API integrations between CMS, e-commerce, ERP, CRM, PIM and payment systems

Stabilization of projects after poorly designed implementations
Every product we deliver is ready to perform from day one — not just technically complete, but prepared for marketing, SEO, AI Search and scaling.
→ Performance-ready
Core Web Vitals optimized before handoff. LCP, CLS and INP targets met — not as an afterthought, but as part of architecture.
LEARN MORE →→ SEO-ready
Clean URLs, correct canonicals, hreflang, sitemap, structured data and crawlable HTML from day one.
LEARN MORE →→ AI Search-ready
llms.txt, Schema.org entity graph, E-E-A-T signals and AI crawler access configured at launch.
LEARN MORE →→ Analytics-ready
GA4, GTM and event tracking implemented and verified before the first campaign goes live.
LEARN MORE →→ Conversion-ready
Forms, CTAs, funnels and tracking aligned with business goals — not left for the marketing team to fix after launch.
LEARN MORE →→ Integration-ready
APIs, webhooks and data flows between CMS, CRM, ERP and marketing tools designed into the architecture from the start.
LEARN MORE →Process & Workflow — SCRUM
Project Research
The common denominator for the client brief and the technical side of a project. Documentation describing functions and mechanisms of the designed product and its market environment.
Prototyping
Building a functional and simple mockup of a website or an application, which allows us to illustrate the activity of its most important functions.
Design
On the basis of functional mockups and the client’s corporate identity elements, we design the look of particular sections of the website and the application. Both desktop and mobile screens are designed.
Programming
The most enjoyable part of the project – the front-end designers cut and style the approved graphic designs and the back-end designers program all the required functions.
Testing
We check if everything works as it should. Our testers check different scenarios and our programmers introduce recommended improvements.
Instalation, Performance & Go life
It’s time for us to move from our development environment to the target client environment. The last round of testing and optimization of the project performance and at last, the final launch!
