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.

At the same time, organisations increasingly need stable teams that can deliver consistently, retain knowledge, and contribute to long-term growth rather than simply complete short-term projects. 

As a result, more companies are turning to integrated external development teams, where experienced developers work as a natural extension of the in-house team while remaining based overseas.

Based on more than 25 years of industry experience and lessons learned from existing clients that have successfully built long-term development teams in Vietnam, here is what companies need to know in 2026. 

Mis-hires can be very costly for your business. Often estimated at 1.5 times the employee's annual salary, and up to 2 times for more specialist or management roles. Beyond the financial costs, a mis-hire also drains time, momentum, motivation, and relationships, both internal and external.
