Proof of concept
De-risk an idea before you hire. A working, demo-ready build that proves the hardest part is possible.
Software you'd otherwise hire a team for — delivered in weeks.
AiTero is a hands-on consultancy for founders and product teams. We take proof of concepts, prototypes and sharp production applications from empty repo to live — with AI as leverage, not as a gimmick.

Focused engagements, built to ship.
we sell outcomes, not hours. fixed scope, fixed date.
MVP & product builds
From spec to a sharp, deployed application — auth, data, payments, all of it — that your first users can actually use.
AI integration
Add genuinely useful AI to an existing product — agents, RAG, evals, guardrails — built for cost and reliability, not hype.
Due diligence & architecture
An honest assessment of a codebase, team velocity or architecture — for founders shipping fast or investors weighing a case.

Klang
AI-powered decision support for music intake in radio. Weighs five signal sources — panel, streaming, surveys, competitors and acoustic profile — and matches against the target audience for a clear verdict: green, yellow or red. A verdict, not a report. Built as a proof of concept in two weeks.

03 / How we work
AI as leverage. Engineering as standard.
senior judgment, multiplied.
the tools move faster — we own the decisions.
P1
Sharpened scope
One call to define the real problem, the single outcome that matters and a fixed date. No discovery theatre.
P2
Build in the open
You see working software within days, not weeks. We iterate on your feedback in tight loops.
P3
Engineering that lasts
AI speeds up the writing; tested, reviewed and documented code is non-negotiable. You own everything we write.
P4
Clean handover
Deployed, documented and explained — so your team can take over, or we keep going. Your call.
04 / The founder
25 years of software. One person accountable.
you talk directly to the one who builds.
no middlemen.
