Software & AI development for companies that ship.
A senior European team. We build software and AI systems that move a business metric — not a demo.
01 · What we do
Product Development
Web, mobile, and platforms built to scale — from first MVP to systems serving millions.
Learn more →AI Solutions
AI integrations, automation, and ML that move a metric — not a demo.
Learn more →Cloud & DevOps
Reliable, observable infrastructure and CI/CD — the layer that lets you ship daily.
Learn more →02 · Industries
Four domains where the work compounds.
We go deep in a small number of industries instead of spreading thin — so the patterns, constraints, and integrations are familiar before we start.

The result is the headline.
FinTech · AI Solutions
−40% reconciliation cost with an AI matching pipeline
A payments scale-up was reconciling transactions by hand. We shipped an AI matching pipeline that cut reconciliation cost and closed the books days earlier.
Logistics · AI Solutions
−63% manual data entry across a freight network
A freight operator was keying every bill of lading by hand. We built an AI document pipeline that reads, validates, and routes paperwork automatically.
SaaS · Product Development
From single-tenant to 3× faster multi-tenant SaaS
A B2B platform was spinning up a separate deployment per customer. We rebuilt it as a multi-tenant product with self-serve onboarding and far lower cost to serve.
04 · How we work
Discovery → Build → Scale.
Discovery
We start with the outcome, not the feature list. A short, senior-led phase to pin down the problem, the constraints, and the fastest path to something real — so we build the right thing before we build it well.
Build
Senior engineers ship in small, reviewable increments. Architecture, development, and testing run together, with code review on everything, so you see working software every week and the system stays sound as it grows.
Scale
We launch carefully, watch the numbers, and keep improving. Observability, performance, and reliability work turn a launch into a product that holds up — and, when you're ready, hands cleanly to your own team.
05 · Why SigmaJunction
Why teams choose us.
Senior engineers only
The people who scope your project are the people who build it. No juniors learning on your budget, no handoff to a B-team after the pitch.
We can share the risk
For the right product we can take part of our fee in equity instead of cash — backing the build when we believe in the outcome, not just billing for hours.
Built to move a metric
We start from the number you need to move and work backwards to an architecture that gets there. The case studies are the proof — not adjectives.
06 · Questions
The things teams ask first.
How do you work?+
Discovery → Build → Scale. A short, senior-led discovery pins down the outcome; then we ship in small, reviewable increments with code review on everything; then we harden, watch the numbers, and scale. You see working software every week.
How senior is the team?+
Senior only. The engineers who scope your project are the ones who build it — there are no juniors learning on your budget and no handoff to a different team after the sale.
What is the partnership model?+
For the right product we can take part of our fee in equity instead of cash, so we share both the risk and the upside. We work out whether it fits on an early call.
How quickly can we start?+
Discovery can begin within days of a first call. The build starts once the scope and the first increment are agreed — we give you a concrete timeline once we understand what you need.
Where are you based?+
We are a senior European team working with clients across the US and EU. We work async-first and keep daily overlap hours with your team.
