What we build
DenkBot builds software that standard packages cannot deliver: a planning platform that matches how your operation actually runs, a customer portal connected to your back office, an internal tool that replaces a fragile spreadsheet empire, or an AI-powered application that does work instead of just storing it.
Two published examples show the range. DFA Connect, built for Dutch recruitment firm De Flexibele Ambtenaar, reads incoming assignments and automatically matches them to candidates — including a drafted proposal. Evolio is a customer feedback platform that collects, analyses and converts feedback into concrete actions. Summaries of both are on the case studies page.
AI-first, not AI-bolted-on
Modern custom software should do more than store and display data. Because DenkBot builds AI systems daily, intelligence is designed in from the start: documents that read themselves, matching that improves, text that drafts itself. Where workflow automation removes steps from an existing process, custom software rebuilds the process around what AI makes possible.
How a project runs
We start small on purpose. After an intake call, in English or Dutch, you get a proposal with a fixed build fee and a monthly fee. A clickable prototype is live within two weeks, so the first feedback round happens on something real. From there we ship weekly: each release is a working improvement, not a promise.
After go-live the monthly fee covers hosting, monitoring, support and continued development. That model keeps incentives straight: we earn by keeping your software healthy and improving, not by billing for every change request.
Technology choices
We build on a modern, boring-on-purpose stack: TypeScript, React and Next.js for applications, PostgreSQL for data, and cloud hosting on European infrastructure. AI features use the model that fits the task rather than a single vendor. The result is software any competent developer can maintain — important, because you own the code.
Frequently asked questions
When is custom software better than an off-the-shelf package?
When your process is your competitive edge, or when you spend hours working around the limitations of standard tools. Off-the-shelf wins for generic needs like accounting; custom wins when the software has to follow your process instead of the other way around.
What does custom software cost in the Netherlands?
DenkBot works with a one-time build fee plus a fixed monthly fee for hosting, maintenance and continued development. The monthly model means the software keeps evolving with your business instead of aging from day one.
How long does a custom software project take?
A working prototype is live within 2 weeks. A first production version typically takes 4 to 8 weeks depending on integrations. We ship in small steps, so you see progress weekly instead of waiting months for a big reveal.
Who owns the code?
You do. The code is delivered in a repository you control. If we ever part ways, you keep a working product and any developer can take over.
Can you take over or extend an existing application?
Usually, yes. We start with a code audit to assess the state of the application, then agree whether extending or rebuilding is the sensible route — including the honest answer if it is neither.
