The spreadsheet became the system
The business runs on sheets, inboxes and one person's memory. Every new customer or order adds manual work, and nobody can see the whole picture.
Apps your customers and team use every day
We scope, design and build the app, then stay with you after launch. Often 4-6 weeks to a focused first version, from €3,000.
The problem
Build cost dropped. Judgment didn't.
AI made a well-scoped product faster and cheaper to build. That only pays off if someone still knows what to build, what to cut and what needs a senior review. That is the part we bring: a free Blueprint, a fixed price for the agreed scope, and AI speed with product judgment.
Unclear scope
Without a locked plan, every conversation adds features. Budget and timeline stretch while the path to revenue stays fuzzy.
The tool doesn't fit how you work
Off-the-shelf software makes your team work around it. Workarounds pile up, and the steps that make you different stay manual.
No ownership
Code, accounts, or IP sit with a vendor or a black-box stack. You cannot hire, migrate, or raise with confidence.
The solution
From scope to product that ships
We cover the full path - research and strategy through design, build, launch, and growth - scoped to your stage.
Scope
Agree who it's for, what it must change, and the smallest useful first version, before any screen is designed.
Design
Flows and interface craft that feel intentional - high-signal screens, not generic AI templates.
Build
AI-assisted custom code or no/low-code, whichever fits your product. Weekly demos, fixed scope.
Launch
Test what users will hit, then go live with monitoring, handoff docs, and a clear cutover plan.
Improve
Post-launch iterations from real usage - fixes, features, and performance that compound after day one.
- A product users can actually try - not another prototype in a drawer
- Locked scope and flat price - no runaway budget or surprise creep
- Code and IP you own, with docs your team can run
- Weeks to launch, not months of speculative build
- Real user feedback instead of internal opinion loops
- A clean stack your next hire or partner can pick up
- We stay involved after launch so you keep shipping
- A clean path off a no/low-code platform or an AI-built prototype when you outgrow it
Use cases
Highest-ROI outcomes by product type
Pick MVP, platform, or rescue. See the outcomes that usually pay back first - before to after, with why it matters.
MVP
Idea to first users
Auth
Core flow
Feedback
Before
A pitch deck and scattered notes - no product people can try.
After
A scoped MVP live with auth, core flows, and a clear path to feedback.
Why it pays: Real signal in weeks, not months of speculative build.

Case studies
Applications we've put to work
Real products for founders and teams - measured in ownership, speed to launch, and systems that hold up after ship.
Why this works
Product judgment, not just tickets
We build our own products too, so we scope for ownership, speed and what users actually do. Our delivery method keeps the build on plan from the first call to launch.
We ship our own apps
Same craft bar we bring to client work - architecture, UX, and the hard calls that keep a product alive after launch.
Methodical from day one
Validated scope, senior delivery, flat price. You see the approach before you see the invoice grow.
Code and IP you own
No lock-in. You leave with a product your team, or another partner, can keep shipping.

“Working with Marko has been an incredible experience from start to finish. He went above and beyond to bring our vision for our CRM platform to life not only executing what we asked for, but also offering valuable suggestions that improved the overall design and functionality.”

Tania Espinoza
Founder & CEO, Global 8 Connect
“Working with Marko at Eterna on the development of my B2B platform has been an exceptional experience. Communication was outstanding from day one; they were always highly attentive to details and proactive. Despite a significant time zone difference, they were incredibly responsive, consistently answering questions and resolving doubts in less than 24 hours.”

“Weekly Loom updates helped me to always know where things stood without chasing anyone, also with Notion portal was a game changer - all decisions, files, tasks in one place. These guys have good processes”

“This platform lets us help the thousands of followers who couldn't access our stretching services before - with our own app. The whole process was cool, and the team solved all the technical challenges we worried about, especially around video security.”

How we ship products
Blueprint
Free. A strategy call, a deeper call to map requirements, then we present your Blueprint live: what we build, what it costs, when it ships.
- Strategy call
- Map requirements
- Blueprint live
Design
Screens and flows for what the Blueprint scoped, shown to you before a line of production code is written.
- Screens and flows
- Design review
- Sign-off before build
Build
Fixed-scope sprints with weekly demos. You stay in control of scope; we stay accountable to the plan.
- Fixed scope
- Weekly demos
- You control scope
Test & launch
After delivery, 2 weeks are free: 1 week of testing and 1 week of fixes. If something doesn't work as agreed, we fix it until it does.
- 2 weeks free
- 1 week testing
- 1 week fixes
Grow
We stay involved as the product evolves: new features, fixes, and ongoing maintenance and support, scoped on a call.

How we build
No-code or custom. We pick the lane.
Both lanes ship real products. The choice is stage, ceiling, and how hard you need to own the stack later.
AI-assisted custom code
Our recommendation when you will keep and grow the product, integrate deeply, or outgrow a platform's limits.
For products you keepClaude CodeNext.jsSupabase
You own the repo and are not locked to a platform. Higher up-front investment. AI assistance without shipping vibecode debt.
No-code (Bubble)
Strong when speed-to-validate matters, the team already lives in Bubble, or the product fits the platform well.
When it fitsBubbleXanoAPI connectors
Lower up-front investment. The app runs on Bubble, so the platform's limits and plans apply. We still spec first, and if you later hit the ceiling, we plan a clean migration to owned code.
