Methodology

From idea to product in production

An agile, transparent and results-driven process. Real functionality every 2 weeks.

01

Discovery & product strategy

We understand your business model, your users and your competition. We define the critical flows, the data architecture and the product strategy before writing a single line of code.

02

Product UX/UI design

We prototype the application in Figma: user flows, design system and every interactive screen. We iterate with you until the experience is exact for your users.

03

Sprint-based development

2-week sprints with working demos. Each iteration delivers real functionality you can test and validate with users. Priorities adjustable sprint by sprint.

04

Integrations & data

We connect the application with your systems: ERP, CRM, payment gateways, third-party APIs. We migrate historical data and set up the synchronization flows.

05

Testing & go-live

Automated QA, load testing, security review and UAT with real users. Production deployment with rollback available and active monitoring.

06

Iteration & evolution

We analyze real usage data (analytics, feedback, support) to prioritize the next features. Your application improves every month based on evidence.

Frequently asked questions

We answer the usual questions before we start working together.

How much does it cost to develop a custom web application?

It depends on complexity. A working MVP starts from €15,000. Platforms with multiple modules, integrations and built-in AI typically range between €30,000 and €120,000. Always a fixed quote before we start.

How long does it take to be ready?

An MVP with the critical flows can be in production in 6-8 weeks. Full platforms between 3 and 9 months. We work with biweekly sprints so you see real functionality from week 2.

Can I launch an MVP and keep adding features?

That's exactly what we recommend. We launch the core that solves 80% of the problem, put it in production with real users and evolve the product based on usage data, not assumptions.

What if I already have a legacy system I want to modernize?

We do incremental migrations without disrupting your operations. We connect the new system with the old one during the transition and migrate data in a controlled way. No big-bang.

Do you integrate with our current systems (ERP, CRM, accounting)?

Yes. We connect with any system that has an API: SAP, Salesforce, HubSpot, Holded, Stripe, banking gateways, in-house ERPs. If it has no API, we build custom connectors.

Does it include artificial intelligence?

Yes. We integrate AI models (GPT-4, Claude, in-house models) into the application: internal assistants, predictions on your data, automatic classification and document generation. It is not an extra, it is part of the product.

Got an application in mind?

We analyze your idea, define the scope and give you a detailed estimate with no obligation.
