secondant

One advisor who sits beside you for three to six months and builds your personal AI practice — on Claude, ChatGPT, Gemini and Grok — until you measurably win back days per month.

Why now

The sector is waiting.
That's your window.

The Netherlands has turned: two in three companies now use AI. Construction sits at the bottom — the lowest sector in the country. That's not a gap. It's an opening. In a market where almost no one does it, the individual advantage is at its greatest.

8.9%AI adoption in Dutch construction — the lowest of all sectors
67%AI adoption among Dutch companies — nearly doubled since 2023

Those who wait pay twice. First in hours. Then in margin.

The engagement

Not a course.
A working practice.

We build on your real work: this week's business case, this month's tender, tomorrow's presentation. Three phases, three to six months.

Phase 1 · Month 1

Foundation

Your working week on the table
  • Audit: where the hours go, what's repeatable
  • Your stack: Claude, ChatGPT, Gemini, Grok
  • Security first: which data may go into which model
  • The start of your digital brain
Phase 2 · Month 2–3

Working practice

On your real work
  • Weekly working session of 60–90 minutes
  • No practice cases — the work that's on your desk
  • One workflow permanently faster per session
  • A direct line in between
Phase 3 · Month 4–6

Independent

Autonomy up
  • Bi-weekly sessions
  • Quarterly upgrade of the stack
  • The direct line stays
  • The secondant makes itself redundant

Discretion, on the record.

No named cases, no logos on a website. Data-processing agreements over your data, business accounts with no training on your information. Arranged before a single project figure goes into a model.

What stands afterwards

Not learned.
Installed.

A set-up AI environment

Secured, professional, tuned to your work. One coherent stack instead of scattered subscriptions.

Digital brain

Your projects, figures and style — captured and searchable. Knowledge that no longer lives only in your head.

5–10 fast workflows

Cost estimates, business cases, tenders, presentations. Structurally faster, not one-off.

Automations

Recurring work that runs on its own: reporting, first drafts, standard documents.

Self-maintained

A way of working you keep up yourself. The secondant makes itself redundant.

The math

Your reclaimed days, measured against your own hourly value. The proof is in your calendar.

Who it's for

People who are the product of their own time.

For entrepreneurs, owner-directors and board members — the people who sign off themselves. Not their teams.

01

The developer

Runs the numbers on land positions himself, writes the investment memo himself, sits with the municipality himself. Loses days to work that a good AI practice does in hours.

02

The owner-director in construction

Cost estimates, tenders, quotes, planning. Knows AI is coming, has no time to figure it out, and won't hand it to a junior.

03

The architect-partner

Practice leadership, acquisition, vision documents, reporting. Wants to protect the design hours by speeding up everything else.

04

The investor

Portfolio analyses, IC papers, market scans. Personal — because the knowledge in their head is the product.

max. 8 clients

Not as marketing — because at this level it can't be delivered otherwise.

What secondant is

Three commitments.

Personal

One on one, at your desk. The secondant serves one person at a time — that's the definition of the word.

On the real work

No lecture halls, no practice cases. You learn it on your own deal. The engagement costs no extra time — it replaces slow hours with fast ones.

Discreet

What happens at your table stays at your table. Your data stays yours — arranged before a single figure goes into a model.

Investment

You do the math yourself.

Say the engagement returns two days a month — a conservative assumption with five accelerated workflows. At an hourly value of €200 to €350 you win back €3,200 to €5,600 a month. The service pays for itself within the engagement. Everything after is profit.

Engagement, per month€ 3,500
One-off setup€ 2,500
Month 4–6, per month€ 2,500
Minimum term3 months

Excluding VAT and model subscriptions. When fully booked, a waiting list applies.

The first move

One conversation.
Then you'll know.

A 45-minute intro call, built around your working week. Afterwards you'll know exactly what a secondant delivers — or that it's not for you. Either is fine.
