Verto Growth invests in Horus Software

Verto Growth acquired 40% of Horus Software in November 2026 from the Tailleur family, which retained the majority, in a round valuing the company at approximately €300–700M. Philippe Tailleur and his sons Jérôme and Benjamin continued to lead the business. Based in Liège, Horus Software develops accounting software for the firms that keep the books of Belgian small and medium-sized companies, together with the finance departments of those companies themselves. Its system reads invoices and receipts automatically and posts the corresponding entries, which removes the manual keying that occupies much of an accountant’s time. More than 4,000 accountants use it, and revenue was expected to reach €5–25M for the current year, against more than six million previously, at an EBITDA margin reported at around 60%. Accounting software binds its users more firmly than most business systems, since a practice that has migrated its clients’ ledgers, trained its staff and built its procedures around one package changes it only at considerable cost, and the switching accounts of competitors’ clients that the company publishes illustrate how far that resistance must be overcome. Language rather than distance separates the Belgian market, and a vendor established among French-speaking practices in Wallonia faces in Flanders a separate body of customers with their own suppliers and habits, which is the expansion the capital was raised to fund, alongside Luxembourg.
