We build software for anything.
A Bucharest software studio that designs, builds and ships production-grade web & mobile platforms — as your product team or as a subcontracting partner when you need extra capacity. Only the sky is the limit.
01What we do
From a blank repo to a product in the App Store — or a white-label sprint for your agency — we cover the full surface so you can plug us in without months of ramp-up.
We take an idea from a blank repo to production — web, mobile and API. One senior team that owns architecture, delivery and the boring details that make software feel effortless.
Multi-tenant, billable, reliable. We've built QR-menu ordering, kindergarten ops platforms and pet-health systems — we know how to make a SaaS that scales and pays for itself.
Deployments, CI/CD, observability and cost control on AWS, Azure and beyond — set up once so your team can focus entirely on shipping.
Websockets, push notifications, payment rails and third-party carriers. The unglamorous integrations that make a product actually work in the real world.
02Selected work
We don't only consult. We build, launch and operate — across proptech, legaltech, pet care and healthcare. Here's a slice.
A clinic-first platform for veterinary practices — patient records, appointments, prescriptions and day-to-day ops in one place, with a direct line to pet owners through the PetFolder ecosystem.
A cross-platform pet-health platform with a QR sharing system, multi-level access scopes and a smart reminders engine generating vaccination, medication and checkup alerts based on species, age and conditions.
A Romanian proptech marketplace connecting owners and buyers directly — zero agents, zero commission. We built the property search, the AI chat assistant that finds homes from a natural-language brief, verified listings and an in-platform digital-contract flow.
A no-account legaltech tool for standardized Romanian documents — car sale, rental, loan-for-use, power of attorney. A guided form with live CNP/ID validation renders the PDF in real time; pay by card and it lands in your inbox, print-ready.
And others under NDA disclosure.
03How we work
No theatre. No 60-page strategy decks. A short, honest loop that gets something real in front of users — and keeps it there.
We write the problem in one honest sentence — and define what success looks like in real metrics, not slides.
Clickable prototypes in days, not months. Tight loops keep everyone aligned before a single production line is written.
Weekly demos, a shared roadmap and production-ready code from day one. No black boxes — you always know what ships next.
We handle launch, observability and on-call as long as you need — then hand over a clean codebase your team wants to inherit.
04Colophon / stack
A focused, well-worn stack. We stay boring where it matters so we can move fast where it counts. Scroll to flip through the layers.
