Etheria is a custom software service based in Bucharest, part of Theta One Digital. Senior system analysts plan and check, AI builds, and you get a system built around your business at a fixed price, in weeks, with a 100% money-back guarantee.
You know you need better tools.
Every road you’ve tried looks risky.
The agency quote
You ask for a simple system and get a six-month plan and an invoice with too many zeros. Most of it pays for meetings, managers and offices, not your software.
The freelancer gamble
Cheaper, until they vanish mid-project. No documentation, no handover, nobody else can continue the work. You’re back at zero, minus the deposit.
The one-size-fits-all subscription
Ready-made apps make you work their way. You pay monthly, forever, for something that half fits, and the rest still lives in Excel.
So most companies wait. And they pay for waiting twice: once in salaries for manual work, and again in the clients who leave for competitors that already digitalised, answer faster and simply work better.
See what waiting costs youHow it works
How a project works
One senior system analyst owns your project, from the first call to handover. Whenever we can, they come from your industry: they already know how a business like yours works, so the conversation goes straight to the point. Four steps, no surprises.

Humans check, then hand over
HumanBefore anything reaches you, the analyst tests every screen by hand and the senior tech lead reviews the code. Then you get the keys: code, documentation and 3 months of included support.
Your effort: use it.


Cheaper, faster and better?
Here’s the honest math.
When an agency quotes €100,000, you’re not paying for code. You’re paying for juniors learning on your project, managers coordinating the juniors, and the office they all sit in.
We work differently. A dedicated project team uses the Etheria AI workflow to write the code, run the tests and document both the plan and the final result. The people understand your business and your workflows and decide what the right solution is. The AI follows their instructions and does the heavy lifting.
You pay for senior expertise, not junior hours. That’s the whole trick. There is no other trick.
Weeks, not months
AI works around the clock. Your project never waits in a queue behind someone else’s.
40–50% below agency quotes
No juniors, no middle managers, no overhead on your invoice.
More testing, not less
Automated tests run on every change, far more often than any manual QA team could.
What we build
What could this look like in your business?
Buyers don’t think in “software”. They think in problems. Here are the six we solve most often.
Replace the spreadsheet chaos
One system where orders, clients and stock live together, instead of 14 Excel files only one person understands.
A portal for your clients
Customers place orders, check status and download invoices themselves, without calling your team.
Paperwork on autopilot
Invoices, offers, contracts, reports: generated automatically instead of typed by hand.
Your tools, finally talking
Accounting, online shop, warehouse: connected, so nobody re-types data between them.
Your numbers, live
A dashboard with today’s sales, stock and cash. Not last month’s, in a report someone had to assemble.
Bookings and scheduling
Appointments, deliveries, shifts: organized automatically, with reminders.
If your team does it by hand today, we can almost certainly automate it.
“Is software built with AI safe?”
Fair question. Here is the answer.
In our process, AI is a power tool, never the decision-maker. Think of a workshop with the best machines: the machines make the work fast and precise, but a master craftsman decides what gets built and inspects every piece.
Two human checkpoints. Two automated ones. Nothing reaches your business without passing all four.
- 01Human check
People set the need, the solution and the plan
A senior system analyst and a senior tech lead define the business need, the solution design and the implementation plan, and approve all of it before the AI starts building.
- 02Automated check
Built and tested piece by piece
AI builds the app one piece at a time. For every piece it runs tests and validations and checks that the app still works, every single time, before that piece reaches our internal testing environment.
- 03Automated check
Continuous security scanning
Every piece we build goes through IT security and vulnerability scanning, continuously, not just at the end.
- 04Human check
Tested by hand, code reviewed
The senior system analyst tests every delivered piece by hand, and the senior tech lead reviews the code behind it.
Results
Real projects, real clocks.
Two recent deliveries: one simple, one hard.
DiggyParty: live in one week
DiggyParty’s way of running events didn’t fit any off-the-shelf booking tool. We built one around how they actually work: developed and fully tested in 6 days, accepted and live in production one week later.
Calculeaza Emisii: four months, not a year
A marketplace of applications for the carbon market: companies subscribe to tools that calculate CO₂ emissions and EU and local levies like the CBAM tax. Heavy regulation, large volumes of data, complex business logic. A competing agency quoted 9–12 months.

A note from the founder
Why I built Etheria.
I spent ten years as an employee and a freelancer, in product companies and in consultancies, on dozens of projects across very different industries. Everywhere, the same conclusion: the process for building software is sound, but the execution, the actual development, eats 70–80% of a product’s time and cost.
When AI arrived, I realised we could build a tool that automates exactly that part: fast, AI-assisted planning, then development carried out by AI strictly to the plan, supervised and checked by people at every step. That is how Etheria was born.
I believe AI is a tool that helps us deliver more, faster and better. I believe just as strongly that human experience stays essential: for understanding a business and its processes, and above all for deciding what the solution should look like. If you have been putting digitalisation off, let’s talk. The first call costs you half an hour.
