FAQ

Questions, answered.

What does dthas build?
dthas builds bespoke software end to end: marketing sites and content platforms, browser-based web applications and dashboards, and cross-platform desktop and mobile apps. Development leads every engagement, with digital and technical consultancy in support.
Does dthas work with clients outside the Netherlands?
Yes. dthas is based in Den Haag and works with clients across the Netherlands and beyond. Engagements run remotely by default, in English, Dutch or Turkish, with occasional on-site time in the Randstad when a project needs it.
What technologies does dthas use?
The stack is polyglot, chosen to fit the problem. Java and Python at the core, with Spring Boot, Django, Angular and Flutter, and hand-built front ends for the web. dthas also works across DevOps, self-hosting and security engineering. No page-builders underneath.
How does dthas price a project?
Pricing follows the engagement: a fixed price for well-scoped work, or a day rate for open-ended or ongoing work. Every quote starts from a short scoping conversation, so the number reflects the real problem, not a template.
How soon does dthas reply?
Within two working days, usually sooner. Enquiries go straight to the engineer, not an account manager, so the first reply is already a technical one.
What does an engagement look like?
It starts with a brief and a scoping conversation, then architecture, build and deployment, delivered end to end. You work directly with the person writing the code throughout. Much of the work ships under NDA; discretion is part of the service.
