High Performance Software Engineering Consultancy
(doing things how they really ought to be done)


We design, build, modernise and
support…
…enterprise-grade applications and platforms for the cloud. (We love all clouds, but Azure is our favourite).

We hang out at the pointy end of cloud technology…
…which makes for some very
interesting work with some very
pioneering customers.

Our applications manage data at
a serious scale…
…and our reputation for excellence in integration joins it all seamlessly together.

Battle-hardened processes make all the difference. There’s done, done well and then…
…there’s done the 345 Technology way.
(Properly, with DevOps as standard).

When we say enterprise-grade
applications…
…we mean the really meaty and
core, mission-critical systems that are the beating heart of our customers’ operations.

We’ve got a bee in our bonnet…
…about building a software consultancy unlike any other
Part of that is having an unusually high ratio of permanent people to contractors so we can build a high trust culture of honesty, learning and respect.
