About Sigma-Tau

A small Danish IT shop — consultancy and web apps you can subscribe to

We're a two-person company based in Køge. We take on consulting projects and run a handful of subscription-based web apps that automate the boring parts of finance and administration.

Most of our work falls into one of three buckets:

Consultancy

We take on projects on contract — usually building, integrating or fixing internal tools. We bill by the hour and report what we did. No black box.

Subscription web apps

Small focused tools you log in to and use. Today that's mainly EasyFlow for invoice approval in e-conomic.

Keeping things running

Once something is in production it needs care. We do the tweaks, the small features, and the boring upgrades that keep an application healthy.

The team

Who we are

Sigma-Tau is the two of us. You'll talk to us directly — no account managers in between.

Development

Does the building. Mostly Angular and Java these days, with a long history of system integration work — talking to e-conomic, Microsoft 365 and whatever else needs to be on the other end of an API.

Administration

Runs the office side — contracts, invoices, and making sure customers don't fall through the cracks. If you have a question about your subscription or a quote, she's the one to ask.
