About me

I am Joost. I advise, build and teach your team to use AI.

I have worked with AI daily since 2022. I tested and developed applications at one of the largest banks in the Netherlands and apply that experience to practical work in smaller businesses.

One specialist. Short lines.

You work with the expert. From first question to handover.

I deliberately work independently. You get my expertise directly, without account managers, internal handovers or layers between your question and the solution.

Decide faster, build faster

You explain it once, to the person doing the work. I can assess a change and implement it without passing it through several people.

Senior expertise throughout

The experience you choose stays on your project. I handle the analysis, tool selection, build and training myself. No handover to someone who is still learning the job.

Your budget goes into the work

You pay for expertise and implementation, without the overhead of a large agency team. We agree on scope, price and delivery in advance. Direct contact keeps decisions clear and progress visible.

The experience I bring

Alongside Tamboer AI, I work through Sprezzatura Consultancy on organisation-wide AI implementation.

Experience at one of the largest banks in the Netherlands

1,000 bank employees work with the AI operation I set up. I tested applications, helped shape data and approval arrangements and taught people to assess outputs. I apply those checks to your work.

Building for businesses

I help SME owners turn repetitive work into useful AI workflows: from quotations and customer email to administration and planning. I choose the tools, build the solution and stay involved until the team can use it.

Training leaders and staff

I guide people from their first AI question to independent use. We practise on their tasks, check quality and document exceptions.

Current knowledge, practical choices

I follow and test developments in ChatGPT, Claude, Copilot, agents and automation every day. I know which tools suit which tasks, and what is worth using in your business. You do not have to keep up with everything yourself.

Why work with me?

As the founder of Tamboer AI, I bring AI into your whole business: I choose the applications, build the workflows and make sure your staff can work with them.

01

Deep AI expertise, applied to your business

Since the launch of ChatGPT in 2022, I have worked intensively with AI: models, agents, prompts and complete workflows. I test developments in practice and translate them into choices that make sense for your company. You get a specialist who understands both the tools and the work.

02

The expert who also builds it

You do not have to find a second supplier after receiving advice. I design the solution, write the prompts, connect your software and test the result. I also designed the AI Operating System specifically for Dutch SMEs.

03

Training that makes your team independent

I train business owners, directors and staff on their own work. I explain what AI can do, where it needs checking and how to choose and adapt the right tools. The goal is a team that works confidently with AI, rather than waiting for me.

How I make decisions

  • First check what existing software can do.
  • Assess quality including review and correction time.
  • Define exceptions and when a person takes over.
  • Train on your work so the team can continue independently.

How I make this site

This site is made the way I work for clients: AI does the groundwork, I check and decide. AI assistants such as Claude and ChatGPT help with research, a first draft and the code. Nothing goes live without my approval. Prices, dates and legal references in the knowledge base come with a source and reference date on the page. AI is never listed as the author: I stand behind what it says.

Spotted something out of date? Email me and I will fix it.

Read how we work together

You work directly with me

From the first question to handover, I take responsibility for advice, building and training. Start with a free AI plan: an AI plan for your whole business, three tailored examples and a demonstration.

I usually reply within a few minutes, including weekends. Prefer email?

AI Operating System

One foundation for your knowledge and daily work

I designed an AI Operating System for Dutch SMEs. It combines your company knowledge, useful AI tools and agreed workflows. A fixed foundation that I configure around your customers, prices, documents and way of working.

Your team gets a working system and training to use and improve it. I build on the software you already have.
