A small engineering firm, run by engineers
SigmaJunction exists because we kept watching good companies buy bad software. We stayed small on purpose: senior people only, no sales team, and engagement terms that make our incentives look like a partner's — including our own capital at risk in equity deals.
What we believe
Say no early
We decline a large share of requests — often because buying is smarter than building. Clients remember honesty longer than invoices.
Seniority compounds
One engineer with fifteen years beats four with two. We hire accordingly and charge accordingly.
Alignment over hours
Fixed prices, owned outcomes, equity at risk. Every model we offer removes the incentive to go slow.

Built by an engineer who kept seeing the same mistake
SigmaJunction started with a simple observation: serious companies were paying serious money for software that didn't move a single business number. Strahinja founded the firm to do the opposite — engineering engagements that start with the metric, not the technology.
Today Strahinja leads the firm the same way every engagement runs: hands-on, in the room for diagnoses and estimates, and accountable for the outcome. The commitments on this site — estimates that hold, first invoice after first delivery, equity terms with our own capital at risk — all trace back to that founding standard.
How we're organised
No account managers, no layers. Every engagement is led by a partner who writes code or scopes systems — the person in your weekly demo is the person accountable for the result.
Built slowly, on purpose
We've grown by keeping clients, not by winning pitches. The milestones that shaped how we work today:
Founded by engineers with one client and one rule: never staff a project we wouldn't put our own money behind.
First dedicated-team engagement. It's still running — the same client, largely the same engineers.
First software-for-equity deal. We stopped being only a vendor the day our name appeared on a cap table.
The AI practice becomes a full third of the firm — built on the same rule: no deployment without a metric.
A senior-only, remote-first team across the EU and US. Still no sales department — the work does that job.
The bar for joining
Every engineer here has shipped and operated production systems for years — and passes the same test we apply to projects: would we put our own money behind their work?
Senior only, verified
Hiring includes a paid working session on a real problem — not whiteboard puzzles. We see how people build, communicate and handle ambiguity.
Writing culture
Remote-first works because decisions live in documents, not meetings. Architecture records, weekly notes, honest post-mortems — all shared with clients.
Partners who build
Every engagement is led by a partner who codes or scopes systems. The person in your demo is the person accountable for the outcome.
Standing commitments, every model
The estimate holds
If we under-scoped, the overrun is ours — never discovered on an invoice.
90-day warranty
Defects in anything we ship are fixed free after acceptance.
First invoice after first delivery
No large deposits; payment follows working software.
Exit at any phase
Stop after any milestone and keep everything produced.
Thirty minutes with a partner — not a salesperson.
There is no sales team to route you through.
