Tassera/Custom work

Custom software, built to last

Besides our own products, Tassera builds software for people and companies: web applications, APIs, data pipelines and internal tools. Built and run the same way as the products on this site.

01 / What we build

Four kinds of work, each already in production

Every capability below runs in one of our own products today, so you can try it before you ask for it.

01

Web applications

Multi-user apps with accounts, roles, subscriptions and live collaboration, from the first version to production.

Already builtJourneyComposer: trips several people edit live, with plans and subscriptions. See it →
02

APIs and data pipelines

Take in large datasets, keep them current on a schedule, and serve them fast through a documented, versioned API.

Already builtLongest Match: public registry and routing data refreshed on a schedule, answered from its own database. See it →
03

Privacy and security tools

Software for sensitive data: encryption in the browser, two-factor login, recovery flows and audit trails.

Already builtTriage Aid: notes encrypted before they leave the browser, so the server cannot read them. See it →
04

Dashboards and internal tools

Admin panels, dashboards and internal tools that bring data from the services you already use into one place.

Already builtDashly: widgets that pull in weather, calendars and news feeds, arranged by each user. See it →
02 / How a project runs

From first message to running software

1

Talk

Tell us what you need, by email or in a call. We ask questions until the problem is clear.

2

Proposal

You get a written proposal: what we will build, how long it takes, and what it costs.

3

Build

Work happens in small steps you can see and try. A working version comes early and grows from there.

4

Hand over or host

We hand over the code and documentation, or we keep it running and maintained for you.

03 / Good fits

Projects we are a good match for

  • A process your team runs on spreadsheets and email
  • An idea that needs a first working version
  • A dataset that should be searchable, or available through an API
  • An existing web app that needs new features, fixes or a new home

A few sentences are enough to start: what you need, who will use it, and roughly when. We reply with questions or a time to talk.
