For business

Fewer slides.
More working AI.

Since May we've been building a company in public with AI as a co-founder. What works for us, we now build inside other organisations: for strategy, research, marketing, finance and customer service. We deliver, your team uses it from day one.

Ideation 53products

Five AI engines proposed 53 products. We picked three.

Customer research 138pages

Feedback from AI personas, summarised by an AI moderator.

Execution 95%

From research to customer service: AI does the work, we steer.

Openness 100%

Every decision is in our public log. Read along before you call.

What we build

Five departments.
One foundation.

AI consultancy that delivers: we start in the department with the biggest gain and build a working application there. For each department you can read in our log how we built it ourselves, mistakes included.

01

Strategy

An opportunity map of your processes, weighed on impact and feasibility, and a roadmap your leadership can steer on. We build the first step straight after.

  • Opportunity map
  • Decision criteria
  • Roadmap
Built ourselves Week 1 · Decision criteria
02

Research

A virtual customer panel that tests your idea before you spend a euro, and trend agents that track your market and competitors. Insight in days, at a fraction of the cost.

  • Customer panel
  • Trend agents
  • Market scan
Built ourselves Week 4 · Virtual customer research
04

Finance

Cost models, scenarios and reports that update themselves. AI calculates and flags, your controller decides.

  • Unit costs
  • Scenarios
  • Reporting
Built ourselves minagi cost model · three scenarios
05

Customer service

An AI assistant that answers customer questions in your own tone, fed by your own knowledge. With clear limits, permissions and a human in the loop.

  • Chat
  • Email
  • Escalation

Meet Mira.

Mira is the face of minagi. She exists only digitally, speaks fluent Dutch and English and looks the same in every video. Here she introduces herself in Dutch, next to Geert-Jan and Jurriën. We build that pipeline for your brand too.

Approach

Humans decide. AI executes.
At your company too.

Step 01

Choose

A sharp intake with your board or team. Together we pick the application with the fastest gain.

Step 02

Build

In one-week sprints. AI executes, we steer, you see something working every week.

Step 03

Go live

The application runs in your own systems, with your own data and in your own tone.

Step 04

Embed

Knowledge, working rules and skills land in your company brain. Your team keeps going on its own.

Step 05

Scale

What works, we roll out to the next department. Every new lesson from our experiment comes with it.

Why us

We build everything
for ourselves first.

Proven in publicEvery tool, every prompt and every misstep is in our log and in our weekly column in Emerce. You know upfront what works and what it costs.

Entrepreneurs who deliverGeert-Jan and Jurriën built digital businesses in e-commerce and B2B. Our yardstick is a working system, measured in revenue, margin and pace.

Formats

Two to four weeks

Sprint

One application, from intake to working result. A customer panel, a cost model or a chat assistant.
