We Build Software Your Business Runs On.

We write code so elegant compilers don't just run it but applaud it, and our architecture is so solid the only thing crashing at night is the dev team.

Engineering team you stop comparing

They rewrote our ingestion path in a long weekend and we never went down again.

Hanna LindqvistHead of Digital · Bremen & Co.

Wrote our checkout from scratch

We needed a Shopify partner who could actually write a checkout, not glue plugins together. Kiloctet did.

Rafael BentoVP Eng · Halcyon Health

Debug at a level most never reach

The fact that they shipped their own language makes sense once you work with them.

Eva LindgrenCOO · Klarheit

Different league entirely

We stopped comparing them to other agencies after the first sprint. Different league entirely.

Daniel OkaforCTO · Vault Atlas

Stack we point new engineers at

The pipeline they shipped is the stack we now point new engineers at. Clean, opinionated, properly instrumented.

Maren SolbergFounder · Lumen Studio

22% → 71% activation

Activation more than tripled after they rebuilt our onboarding. Fundamentally better path to value.

Avi PereiraHead of Platform · Polar Express

App store reviews flipped

Took our 3.2-star app to 4.7 stars over two release cycles. They argued with our PMs on the right things.

Lina OstrowskiVP Eng · Voltari

Rust firmware on real hardware

They write Rust firmware that actually runs on real hardware. Most agencies stop at the cloud layer.

How we work

Our process — simple, seamless, streamlined.

From “we should talk” to “shipped to production” in three clear steps, no surprises.

01

Join an exploration call.

Tell us about your business on a 30-minute discovery call. We discuss team structure, success criteria, timescale, budget, and the skills you’ll need.

~30 min · Free
02

Shape the solution & team.

In a matter of days we finalize project specifications, agree on an engagement model, and select and onboard the right team for the work.

A few days
03

Ship & track performance.

Once milestones are agreed we get to work immediately. We track progress, report weekly, and adapt continuously to your changing needs.

Our stack

Built with tools we trust in production.

The languages, frameworks and platforms we ship serious software with — picked because they survive 3am pages, not because they trended on Twitter.

What we do

Engineering across the stack — from kernel to checkout.

Six services. One small team that's shipped sixty-two production systems.

.01 — Custom Development

Production software, built end-to-end.

Web, mobile, desktop and backend — hand-rolled where you need it, and on solid frameworks when you don’t. One team, one codebase, one set of opinions.

Real stories

From their desk to yours.

Founders and engineering leads talking about what we shipped. No marketing team in between.
