Custom Software Development
Bespoke, End-to-end custom software development services engineered to solve complex operational challenges and scale your business efficiently.
DetailAetarix is a software partner for companies that have outgrown the prototype. Custom platforms, cloud architecture, AI automation and the growth engine around them — scoped in writing, delivered on a schedule you can plan against.
We started in 2016 as four engineers who were tired of watching good projects fail on delivery rather than on technology. Ten years on, Aetarix runs engineering, cloud, AI and growth work for companies whose systems already carry real money and real risk.
We are deliberately senior, deliberately small per project, and deliberately explicit: the scope is written down, the burn is visible, and the handover is a document rather than a promise.
Bespoke, End-to-end custom software development services engineered to solve complex operational challenges and scale your business efficiently.
DetailHigh-performance full-stack web and mobile application development built for ultimate security, speed, and seamless cross-platform scalability.
DetailRapid, strategic MVP prototyping and development built to accelerate market validation and win over early adopters.
DetailWe staff senior-first, work in your repository from week one, and write the estimate down before the invoice. Every engagement ends with your team able to run what we built without us.
No bait-and-switch staffing. You meet the people who will write the code, and they stay to the end of the engagement.
A written statement of work, a weekly demo, and a dashboard showing hours against estimate. Surprises get raised, not absorbed.
Threat modelling at design time, dependency and secret scanning in the pipeline, and an audit trail your compliance team can read.
Runbooks, architecture decision records and a walkthrough with your team. Independence is the deliverable, not the upsell.
Not add-ons, not premium tiers. These are the defaults, written into every statement of work we sign.
Deliverables, dates and assumptions on paper before work starts.
Hours against estimate, published weekly, visible to your finance team.
Dependency, secret and licence scanning gates every merge.
Working software every two weeks on a staging environment you own.
WCAG 2.2 AA verified before release, with the report attached.
Runbooks, decision records and a walkthrough with your engineers.
