With software we build ourselves and run in Switzerland and the EU. [What we replace](#loesungen) [Talk to us](https://elchi.dev/en/kontakt) Midnight, 3 October 2026, Swiss time. Five stars in Andromeda, Paris in Lacerta, each 0.2 to 1.0 degrees from the zenith of its city. Point at a star to see its servers. Stereographic projection, east to the left. Stars to magnitude 6.5 from the Bright Star Catalogue (Hoffleit and Warren, CDS V/50). Solutions ## What we replace Processes that cost companies and administrations time today, and what we replace them with: by industry first, then by task. ### By industry - [**Fiduciaries and accountants**Receipts that arrive without you chasing them.](https://elchi.dev/en/loesungen/branchen/treuhand) - [**Medical and therapy practices**Fewer calls at reception, less paper in the process.](https://elchi.dev/en/loesungen/branchen/praxen) - [**Trades and construction**From timesheet to invoice, without retyping.](https://elchi.dev/en/loesungen/branchen/handwerk) - [**Municipalities and public administration**Forms that get finished online.](https://elchi.dev/en/loesungen/branchen/verwaltung) - [**Law firms**Share documents instead of emailing them.](https://elchi.dev/en/loesungen/branchen/kanzleien) - [**Property management**Repair reports that arrive complete.](https://elchi.dev/en/loesungen/branchen/immobilien) [All industries](https://elchi.dev/en/loesungen/branchen) ### By task - [**One sign-in for every application**One account for all of them instead of a password per application, with passkeys, a second factor and sign-in with the company's own account.](https://elchi.dev/en/loesungen/anmeldung) - [**Business email, stored in Geneva**Instead of email at a US corporation or on an old server of your own: EMX (Beta) on your domain, in every mail app, for CHF 4 a mailbox.](https://elchi.dev/en/loesungen/e-mail) - [**A website that is found**Instead of a slow page nobody finds: a website at a fixed price, measurably fast, readable for search engines and AI assistants.](https://elchi.dev/en/loesungen/website) [All solutions](https://elchi.dev/en/loesungen) Products ## What runs today Two products we build and run ourselves.

Joined like the servers are joined, those stars are our mark. [How the cluster is built](https://elchi.dev/en/infrastruktur) servers 8 server providers 5 countries with servers 4 copies of every database 3 Cluster inventory, as of 8 October 2026. Not counting the DNS services Cloudflare and ClouDNS, which only resolve names. Trust ## Where your data is Accounts, mailboxes and content sit on our servers in Switzerland, Germany, the Netherlands and France, at European providers. For two tasks we still use services of US groups, and we name them: Resend for notification mails such as an address confirmation, and Stripe for EMX payments. Cloudflare only holds our DNS zones. **The path of an email at EMX.** An email comes from a sender on the internet to mx.emxmail.ch, where SPF, DKIM and DMARC are checked and the spam filter runs. Messages and attachments are stored encrypted in Geneva, sealed if you want; the database is in Frankfurt, with copies in Nuremberg and Paris. Mail is read in the web client and the app with sign-in through EAuth, in Outlook, Apple Mail and on the phone over IMAP with an app password, and by your software through the API with a token. Our own servers deliver outgoing mail, signed with DKIM, to recipients on the internet.
