Services

One team for the code and the machines it runs on.

No hand-offs between agencies and providers. We build it, host it, watch it and fix it.

01 / BUILD

Custom development

Web applications, APIs, internal tools and automations, built in-house around the way your business actually works.

02 / INTEGRATE

Integrations & automation

Connect the systems you already use — messaging, payments, invoicing, CRMs — and remove the manual steps in between.

03 / OPERATE

Server administration

Monitoring, hardening, updates, backups and incident response for servers you own or rent from us.

04 / HOST

Managed hosting

Reliable hosting for websites and applications, with the technical work handled for you.

05 / COMMUNICATE

Business email

Professional email on your own domain, with spam and phishing filtering and properly configured deliverability.

06 / RENT

Dedicated & virtual servers

Servers provisioned, secured and ready to use — managed by us, or handed over with full access.

Product · tUi Push

Instant mail notifications on iPhone — for your own mail servers.

Native Apple Mail only shows new messages instantly for a few large providers. tUi Push brings real push notifications to mailboxes hosted on your own infrastructure.

Hosting control panels More panels — coming soon Standalone mail servers — coming soon

  1. Connect your mail server

    We enable tUi Push on your server. Your mail stays where it is.

  2. Users keep the native Mail app

    No extra apps to install. Accounts are set up in Apple Mail as usual.

  3. New mail, instantly

    The moment a message arrives, the iPhone gets a push notification — no polling, no delays.

  4. Built for providers and companies

    For hosting providers that want to offer it to their customers, and for companies running their own mail.

Why tUi

Small team, end-to-end responsibility.

In-house, end to end

Development, hosting and operations under one roof. Nothing outsourced.

We run what we build

The people who write the code also keep the servers healthy.

Security by default

Hardened servers, filtered email and tested backups — not optional extras.

A direct line

You talk to the engineer doing the work, not to a ticket queue.

Our story

Built by people who got tired of hand-offs.

Nov 2023Founded

tUi was founded in November 2023 with a simple idea: the team that writes your software should also be the one keeping it running. Too many businesses were stuck between a developer who built the app and a provider who hosted it — and nobody owned the problem when something broke.

So we brought it all in-house. We started by building custom tools for businesses, then took over the servers, hosting and email those tools depended on. Along the way we kept running into the same gap — iPhone users on independent mail servers never got instant notifications — so we built tUi Push to solve it.

Today we design, build, host and operate — and we're expanding tUi Push to more platforms and standalone mail servers.
