Welcome to CERTAINCE
We help specialized businesses do more with the team they have – from recurring back-office work to research and development – with AI-assisted custom software. We focus on custom software, agents where they make sense, engineering, CI/CD, and testing.

Our mission is simple: companies should approach AI pragmatically – no head in the sand, but no panic either. Most know AI has potential – what is unclear is where to apply it in their own business. That is exactly what we show you: use AI today where it already creates measurable value. Leave it out where it does not. And expand as the technology improves. Because AI has fundamentally changed the economics of software: work that never used to be worth doing this way – from recurring back-office work to research and development – can now be built production-ready as an app, an agent, or a deliberate combination of both.

Founder & Developer
We start with the workflow, not the platform. If a classic app makes the process clearer, we build it. If an agent can read data, prepare information, or execute steps, it gets clear boundaries, tools, tests, and logs – and where context is missing, a human reviews at the right level.
Product development, engineering, CI/CD, automated testing – it all comes from one source. The result is software that fits your business, runs reliably, and grows with you – drawing on experience across manufacturing, machinery, trade-booth construction, medical devices, and e-commerce.

Our goal is real value, not billed hours. You work directly with the developer, who sees the big picture and knows what actually makes a business app succeed in daily use. So software does not just work technically – it makes your work measurably better.

We like starting with what slows your business down, whether that needs an app, an agent, or both, and where custom software would create real value.
