Overview
kChat is a team messaging service with public and private channels, threads, direct messages, file sharing up to 100 MB per file, message search, webhooks and free guest access for external partners, who see only the channels they are invited to. It includes AI features from Infomaniak’s Euria assistant, such as thread summaries and voice-message transcription.
kChat cannot be ordered separately: it is part of kSuite, with a free tier limited to 90 days of message history and paid kSuite Pro plans with unlimited history. Its published clients are based on the open-source Mattermost platform, and imports from Mattermost, Slack or Teams are offered on request. Infomaniak states that data in transit and at rest is encrypted and stored in Switzerland; end-to-end encryption is not advertised.

Swiss footprint
Five independent questions. A Swiss company is not automatically Swiss-hosted — and vice versa. How the footprint is assessed

- Legal jurisdiction
- OwnershipIs the company ultimately Swiss-owned?
- Yes — Infomaniak SA (controlled by the Infomaniak Foundation) · SwitzerlandVendor claim[3]
In May 2026 founder Boris Siegenthaler transferred the majority of voting rights to the Infomaniak Foundation, a Swiss public-interest foundation. In September 2026 the SIX-listed Perrot Duval Holding SA acquired 100% of Infomaniak Group SA in a reverse takeover and was renamed Infomaniak SA (ticker INFO, trading since 1 October 2026). The Foundation holds all unlisted, non-transferable Class A shares and the majority of voting rights; the listed Class B shares carry a minority of votes. The founder and about 30 employees also hold shares. Infomaniak Network SA is the group's operating company and contracting entity; its place under Infomaniak Group SA is inferred from the shared address, management and group references rather than stated explicitly in the sources consulted.
