Memority

Memority is a French Identity-as-a-Service (IDaaS) vendor built around Identity Factory, an identity and access management platform covering employees, partners, customers, and connected devices. The technology has a longer history than the current company: it originated inside Accenture, and Memority became an independent company in June 2023 when its founders, Gilles Casteran and Francis Gregoire, bought it out of Accenture – meaning the platform arrives with years of production deployment behind it rather than starting from a blank slate.

Note: this profile was created for a company listed in vendor records as “Zygon,” a Paris-founded SaaS-identity-governance and shadow-IT-detection startup (est. 2023). In March 2026, Memority acquired Zygon and folded its team and technology directly into Memority’s platform under the banner “Zygon is joining Memority” – Zygon’s identity-visibility and unmanaged-application-detection capabilities (finding apps and accounts used outside declared IT inventories) are being absorbed into Memority’s broader Identity Factory product rather than continuing as a separate company. Because Zygon no longer operates as an independent entity, this profile covers Memority, the current operating company, rather than the now-discontinued Zygon brand.

Memority raised a EUR13 million Series A in 2025 led by Tikehau Capital’s Brienne cybersecurity strategy – its first institutional round since regaining independence from Accenture – and the Zygon acquisition, its first, was funded off the back of that raise. Based in the Paris area (Puteaux) with a reported 51-200 employees, Memority is positioning itself as a European, sovereignty-conscious alternative to large US-based IDaaS platforms (Okta, Ping Identity, Microsoft Entra ID), a pitch that has real appeal for European public-sector and regulated buyers navigating data-residency and vendor-concentration concerns, even though it remains a smaller player by revenue and market share than the incumbents it is positioned against.
