How long placements run, and why they end

About half of Tunga's open-ended placements since November 2022 ran for more than a year, and about 1 in 4 for more than two years. The longest current placement has been running for more than four and a half years.

What happened to Tunga's open-ended roles in 2025, as of 31 December 2025. A role is the position at the client: when Tunga replaces the professional, the role continues.

Leaving and replacement

• Placements ended because the professional left for another job: about 1 in 56 in 2025, and none so far in 2026.
• For comparison: in the Eraneos/Whitelane Dutch IT Sourcing Study 2025, turnover at the supplier was named as a weakness in 22% of 652 supplier relationships. European tech companies lose on average 12% of their engineers a year (Ravio, all reasons for leaving).
• Replacement: at no extra cost and without a time limit. The successor usually starts within a month of the previous professional's last day, sometimes within days.
• Why replacements happen: between 2023 and 2026, more than a third followed a change in what the client needed, such as a more senior profile or a different stack. About a third followed a professional leaving, and about a quarter underperformance or a fit that didn't work.
• Professionals moved off a client on Tunga's initiative: none since Tunga was founded in 2015.

Professionals and the account team

• Time with Tunga: about 1 in 5 professionals have worked through Tunga for 4 years or more, across clients; the longest for 7 years.
• More than one placement: about 1 in 4 professionals have had more than one placement through Tunga, some up to 4.
• Account team: everyone on it has been with Tunga for at least 4 years.
