Your custom software delivered to production every week for a fixed budget.

A model where you pay a fixed monthly budget for continuous development. Project management does not rely on initial estimates: the scope adapts to what you learn. You change priorities at any time, with no amendment.

At DEVEDANOS, you use the software in real conditions from the very first weeks. Working software is the primary measure of progress. Our Continuous Delivery discipline allows us to ship features continuously. Waiting months for a full delivery, or following demonstrations that show what progresses without showing what does not work yet, only delays the moment you get the answer to this very question.

Custom software development works like the relationship between an author and a printer. You know your business, your users and your information system. We master software engineering. Your involvement is essential: acceptance testing of features, regular feedback, priority decisions. Without that, no provider can deliver software that matches your needs.

No invoice issued. The trial period lasts up to 15 working days. If you decide not to continue, no payment due. The produced code remains the property of DEVEDANOS.

Three cases must be distinguished. A regression (a feature you had tested and approved behaves differently after a change): our zero-regression guarantee applies, we fix it and add an automated test that prevents its reappearance. A defect found during acceptance testing (the delivered behavior does not match what you expected): either the specification we prepared together contained an error, or the feature does not respect the specification. In both cases, the work is not finished, we finish it. A behavior change requested on a feature already tested and approved: that is an evolution, not a bug.

Our development process is built on small steps. Each feature is specified with you, built, tested, and deployed individually. Because each step is small, defects are spotted fast and fixed fast. Automated tests verify the expected behavior with every change we make. You test the real application yourself and confirm each feature does what you need. In production, monitoring detects unexpected behavior early. And our zero-regression guarantee means every bug fix is locked in by an automated test: once fixed, it stays fixed. The usability of each interface is validated through real usage in production.

An application is not a monolithic block, but a set of independent features. The Manifesto for Agile Software Development and lean principles push us to prioritize high-value features from the start. Each feature is specified, developed, tested, accepted and deployed individually. Our Continuous Delivery discipline guarantees easily modifiable code, quickly adaptable to new needs, and an application in a working state at all times. That is what allows us to deliver usable applications from the first weeks, in just a few features.

As soon as the quote is signed. We run a framing workshop to identify what will generate the most value for your users (Impact Mapping, OKRs, prioritization). Two options depending on your preference: collaborative or delegated. You get a clear direction from the first week. Development starts immediately after.

Custom applications: SaaS platforms, marketplaces, e-commerce, job boards, business applications, CRM, business management software, monitoring, client portals, extranet, admin consoles and AI integration into existing systems. Whether you want to automate business processes, overhaul an unsuitable off-the-shelf solution or modernize an existing information system, we build the software tailored to your specific needs.

No reliable tool exists today, according to scientific research, to estimate the cost of developing custom software. Estimates systematically turn out wrong, and the vaguer the project, the higher the quote. But software is not a monolithic block. It is a set of independent features, and that reality changes everything. Since each feature can be specified, developed, tested and delivered individually, the real question becomes: what to deliver first to alleviate your problem as fast as possible? That is exactly what Continuous Delivery, lean and agility enable. At DEVEDANOS, you pay a fixed monthly budget for delivered features that you have tested and approved. The more we add, the more your problem recedes, with the long-term prospect of solving it entirely. We build this budget with you during the discovery call.

The trial period lasts up to 15 working days. During this time, the source code remains hosted on our systems. If you request access to the code before the end of the period, the trial ends and invoicing is due at the end of the month, payable within 15 days.
