In 2026, companies are facing a growing challenge: how to scale tech- and development teams without losing control, quality, or company culture.

Global economic uncertainty, rapid technological change, high cost pressure, and a shortage of specialised local expertise are forcing more businesses to rethink how they build tech teams. Competition for skilled developers remains high, while traditional outsourcing models often leave companies with limited control, weak cultural alignment, and high turnover.
