DetaVast
Hire first, then take over cost-free.
DetaVast combines hiring and employing: you hire a data professional, and after the agreed number of hours worked you take them over cost-free. No takeover fee, no buyout sum (rule of August 2026).
You choose DetaVast when you want to employ someone but first want to see whether the work and the cooperation fit. The shortest track is 1,200 hours, roughly seven months full-time (August 2026).
In the market you can usually only take someone over cost-free after 2,000 to 2,200 hours worked (market picture, August 2026). At NewData it starts at 1,200 hours.

The route in three steps
How DetaVast works, from start to takeover.
- 01
You choose a track
You choose a track of 1,200, 1,600 or 2,000 hours; a shorter track carries a higher hourly rate, because the takeover comes sooner.
- 02
The hours count
You pay per hour worked, at the rate of the chosen track. If a candidate does not fit, the hours carry over to the next one, up to at most half of the track.
- 03
Take over cost-free
After the agreed number of hours worked you take the professional over cost-free. No takeover fee, no buyout sum (rule of August 2026).
Tracks

All amounts excluding VAT, rates of 12 August 2026. 1,200 hours is roughly seven months full-time. The professional’s pay follows the client’s remuneration scheme. A worked example is in hiring someone and employing them later, explained in the blog.
In depth
What does cost-free mean at takeover?
The takeover after the agreed hours is cost-free: no further invoice follows, not even a partial one (rule of August 2026).
The half-way rule protects both sides: if a candidate does not fit, the hours carry over to the next candidate, up to at most half of the track. The new candidate always works at least half personally.
Prefer plain hiring without a takeover agreement? Choose secondment without a takeover agreement. Moving to DetaVast later remains possible through switching between models.
Proof
Does it really work that way?
At Robeco, a data student carried out the migration from Tableau to Power BI, with secured scripts and documentation. The data student joined Robeco directly after graduating.

Candidate replacement
What if a candidate does not work out?
If a candidate does not work out, the hours worked carry over to the next one. Never more than half of the chosen track carries over, so the new candidate always works at least half personally. That ceiling is calculated each time over the track you choose for that new candidate.
For example: 700 hours have been worked and you choose a track of 1,200 hours again, then 600 hours carry over and the new candidate works the remaining 600 personally (rule of August 2026).
This applies only to replacement. If you expand and add someone, no hours are deducted; the new colleague simply starts a track of their own. How a model switch works is at switching between models.
Questions
Frequently asked questions about taking over
What is DetaVast?+
DetaVast is hiring with an agreed endpoint: after a fixed number of hours worked you take the professional over cost-free, without takeover fee or buyout sum. At NewData you choose from tracks of 1,200, 1,600 or 2,000 hours (August 2026). You first get to know someone in the real work, and only then decide.
What does DetaVast cost?+
The hourly rate depends on the chosen track: € 70.00 per hour for 1,200 hours, € 65.00 for 1,600 hours and € 60.00 for 2,000 hours, all amounts excluding VAT (August 2026). The takeover itself then costs nothing. A shorter track carries a higher hourly rate, because the takeover comes sooner.
What happens if the candidate does not fit halfway through?+
Then NewData brings in the next candidate, and the hours worked carry over up to at most half of the chosen track (rule of August 2026). The new candidate therefore always works at least half of the hours personally. You never take someone over cost-free who has not proven themselves in your own practice.
