Custom software delivered to production every week, on a fixed monthly budget. Here is who carries this promise.
DEVEDANOS is a custom software development agency. Your software is usable from the first days, in just a few features, on a fixed monthly budget, through an adaptive continuous-delivery approach. Founded by Sébastien Nobour, available in Versailles and Maastricht, it serves France, Belgium, Luxembourg, the Netherlands, and Germany.
What we have seen
Project after project, the same mechanism at work. A figure negotiated to close a sale. A specification frozen that reality outpaces. Milestone-based billing where every signed phase gets paid, without validation in production.
52.1% of projects exceed their budget (Flyvbjerg, How Big Things Get Done, 2023 (16,000 projects)). Of features delivered, only one in three improves the target metric (Kohavi et al., Microsoft Research, 2009).
The result is structural. We chose another standard.
The standard we hold
Our standard is measured in production releases. At least one per week. Every approved feature goes to production the same day.
A fixed monthly budget. You decide the scope, as reality shifts.
Fifteen days to form your own opinion. No invoice if you decide not to continue.
The engineering that carries this standard is continuous delivery (Farley, Humble). Our Approach page details the mechanics.
I have seen, project after project, the same result. Weeks becoming months, budgets going off-track, teams changing mid-project. Without anyone able to say whether we were building the right thing.
Agility is the base. No two software projects are alike. Dave Farley and Jez Humble named continuous delivery, the first principle of the Agile Manifesto in practice. Frédéric Leguédois taught me to fix cost and quality, and to let you steer the scope.
My interests aligned with yours. Structurally.
