# 20 Thousand Leagues

20 Thousand Leagues is a senior advisory and implementation practice for mid-market companies. It helps leadership teams find what is worth building, then build it with the right specialists — or say when building is not the right answer.

## What the practice does

- Clarifies ambiguous technology, data, product, and organisational problems.
- Helps AI investments reach production and adoption.
- Improves data foundations, trust, architecture, and governance.
- Shapes product and commercial direction.
- Leads transformation programmes and hands-on implementation.
- Provides named senior specialists for defined delivery windows.

## How the work starts

Most engagements begin with a Depth Check: a structured working session that reads the situation through outside-in, inside-out, and bottom-up lenses. The next step may be analysis, strategy, execution, or a recommendation to defer.

## Evidence

The Cases section describes delivered work across AI implementation, data trust, productisation, scaling, commercial transformation, and programme leadership. Case pages include the situation, work performed, and reported outcomes where available.

## Practitioners

The practice is built around Simon Kaastrup-Olsen, Lars Brebøl, and Sune Edmund Pedersen. Their backgrounds cover commercial strategy and product, data architecture and technical governance, and transformation governance and change management.
