Context & Ambition


In 2018, CAPZA and Horizon CEO, Sylvain Thieullent, decided to enter an Management Buy Out, alongside with key Horizon staff and Industry Veterans as board members.


The ambition of the investment is to support the company’s development plan in Agency Trading, Hosting services and expansion to Americas.


On top of supporting organic growth, CAPZA accompanies Horizon in making bolt-on acquisitions to increase the footprint and value to their customers.

Our Role

In 2018, CAPZA invested in the company as a majority shareholder alongside the management team as part of a primary MBO.


Our involvement enabled the management team to increase its ownership of the company’s capital and also to open up the capital to any employees who were interested. Since we moved in, Horizon Software has hired some key personnel (CFO, Head of Marketing, General Manager Asia) and continued to expand internationally in mainland China and Canada.

Horizon Software's management team and I were convinced by CAPZA to support us in this new phase of growth. We share a common objective of creating value through high quality service requirements for our customers. This alignment will allow us to move forward much faster while remaining focused on Horizon Software's expertise.
