What does data consultancy cost?

A first conversation comes with no obligation. After that it starts with an exploration of eight advisory days, spread over two to six weeks, with a fixed scope; that costs € 7,500 excluding VAT. Prefer a single day first? A start day costs € 1,000 and delivers a prioritised list and our advice on whether the exploration is worth it. What a project costs after that depends on what has to be built and what is already in place. We can only say that after the exploration, and sometimes the answer is that you do not need to build.

Outsource data science or do it yourself?

That depends on how much work remains after the first project. If little, outsourcing is cheaper than a team of your own that goes idle after the build. If a lot, you build your own team and we help with specialists in your team until it stands. In the blog Data quality and AI: why projects run aground we describe what that team has to be able to carry.

What is the difference between data consultancy and AI consultancy?

Data consultancy is about the foundation: which data exists, whether it is reliable, how it reaches the people who decide, and what that requires in platform and definitions. AI consultancy is about whether a model adds anything and how it gets into production. In practice an AI question often starts at the data foundation, and we say so.

How long does a data consultancy engagement take?

The exploration takes two to six weeks, depending on how many sources and departments are involved. After that you know what has to be fixed first and what it costs. If it becomes a project, it goes through six steps from scope to support; how long that takes depends on the data and on the work process it has to land in. We set the measuring point at twelve months.

Which consultancy has experience with data in my sector?

Twentynext has worked since 2014 for healthcare and life sciences, security, industry and maritime, retail and ecology. Named examples: the data platform for AxionContinu in elderly care, the analysis for the Dutch police within Q-LAB and the crime room for DITSS. The seventeen cases are grouped by question, because the same technique turns out to work in more than one sector.

Is there a subsidy for the exploration?

For SMEs, regional schemes exist that cover part of external advisory costs, such as the North Brabant scheme Datamaturiteit MKB via the data coaches of Brainport voor MKB, Midpoint Brabant and REWIN, or the Groeiversneller of Oost NL for growth companies in Gelderland. Whether and how much is covered depends on your location, sector and the available budget; the Brabant scheme had reached its ceiling in September 2026. In the first conversation we look together at which route fits. You submit the application yourself; we supply the quote and the advisory report.

Is data advice different from data consultancy?

Not in any essential way: data advice is another name for what we call data consultancy. At Twentynext it means advice on your data from the people who will build and maintain it afterwards: which decision needs to improve, which data has to be reliable for it and what needs to be in order first. The exploration of eight advisory days is the form in which that advice is given.

Are you looking for a data analysis firm or a data consultant?

That depends on what has to happen after the analysis. A data analysis firm delivers the analysis and the report; after that, your organisation has to take it further itself. At Twentynext the analysis is the beginning: the same people then design the platform or the model, build it and maintain it. If you only need a one-off analysis, we will tell you so.

Does Twentynext also do BI consultancy?

Yes, as part of data consultancy. For us, BI consultancy is about the reports and management information teams work with every day: the same definitions for all departments, figures that can be traced back to the source, and authorisation handled in the layer itself. The data and reporting platform for AxionContinu is an example, with analyses and AI applications for care professionals on top.
