TeelsaStart a project

We build and run the software your organisation depends on.

Teelsa takes software from specification to production, then stays responsible for it: monitored, patched, backed up and reported on in plain language.

Under one roof

One company,
all the way through.

Nothing is handed off

Design, engineering and infrastructure sit in one company, so no part of the work crosses a boundary.

Already in production

We run our own products in production today, maintained by the team that built them.

Delivery is the midpoint

Monitoring, patching and backups continue after launch, reported on a schedule you set.

Services

What we do.

Five services. Most engagements begin with one and extend into the others.

01

End-to-end software development

Web and mobile systems taken from requirements through design and engineering to release.

02

Website development and hosting

Marketing and platform sites built, deployed to infrastructure we configure, and maintained after launch.

03

Server and email administration

Provisioning, hardening, patching, monitoring and backups for Linux servers. Mail domains configured for reliable delivery.

04

Managed self-hosted platforms

Collaboration and messaging platforms on infrastructure you own: updated, backed up and available.

05

Ongoing engineering partnership

A standing engineering team for organisations that need software built, extended and run over time.

Client work

Already running for other people.

5

Organisations managed in full: website, email and Linux or Windows VPS hosting that we provision, harden and run, under a single arrangement with one point of contact.

24

Websites built and deployed for clients, then kept patched, backed up and up to date long after launch.

24/7

Monitoring on every system we run, with alerts going straight to the people who built it.

Why teelsa

The whole system, handled.

Four things that hold true on every engagement, whatever the size of it.

01

End to end

One engagement covers specification, design, build and production. Nothing is handed off.

02

We run what we build

Systems stay under our care in production: monitored, patched, backed up.

03

Plain communication

Progress, risks and costs reported in plain language, on a schedule you set.

04

Working internationally
