DN3 (dn3.dev) is an agentic software studio that sells fixed-price software: MVPs in production in 14 days for €15k, €20k or €25k, extra sprints at €5k. A pipeline of agents writes the code under the supervision of a senior engineer.

DN3 is an agentic software studio. Its starting assumption is that the marginal cost of building software tends to zero, and that the price of a prototype can follow production cost instead of hours worked. DN3 publishes a fixed price list that applies to every client: MVPs in production in 14 days for €15,000, €20,000 or €25,000 depending on the number of flows, extra 7-day sprints at €5,000, continuous evolution at €5,000 a month. A pipeline of coding agents, led by a senior engineer, specifies, builds, tests and releases the product. The client owns the code and infrastructure from day one. Each year DN3 also selects three or four startups for which it builds the product at a reduced price in exchange for a minority stake. Website: dn3.dev.
