The deal

One pod. One month. Built.

A pod is your seat at the table for the month. Flat price, paid up front, no SOWs, no setup fees, no surprises. Cancel on day one, cancel on day twenty-nine - every euro comes back. The only thing you're really subscribing to is the work.

Price

€10,000 / month. Per pod.

Paid up front, ex. VAT. Same number every month for as long as the pod is yours. No retainers, no setup fees, no hourly meters spinning quietly in the background.

Output

Worth ≈ two senior devs.

We pair seasoned engineers with serious AI tooling. The output of one pod lands close to two full-time devs. We don't guarantee how many people touch the keyboard - we guarantee what ships.

People

Senior only.

Every engineer on your pod has years of production work behind them. No juniors, no interns, no "we'll figure this one out on the job."

Speed

No hiring loop.

No recruiters, no three-round interviews, no three-month notice periods. Sign on Friday, meet the team on Monday, see code in the repo by the end of the week.

Scale

Stack pods as you scale.

Need more throughput? Add a second pod. Need less? Drop one next month. The model bends to your roadmap, not the other way around.

Ownership

Your code, your repo.

Everything is in Git, owned by you from day one. If you ever leave, you leave with a working codebase and the full history.

Source

Never in a training set.

No customer source touches a model that trains on it. Industrial-grade tooling, boundaries tighter than most internal teams bother with. NDA on day one, on us.

Guarantee

Cancel any day. Get every euro back.

No questions, no clawback clauses, no "well, technically." Cancel on day twenty-nine and the whole month refunds. If we haven't earned it, we don't keep it.

The rhythm

One meeting. Then we ship.

An hour to align, then we go quiet. The good kind of quiet - full of code, weekly demos, and Slack messages that don't open with "got a sec?"

Sofia ↔ Worldwide

We've been here for a while. You just hadn't met us yet.

We started in Sofia in 2016 - remote-first before the rest of the world figured out what that meant. Nine years, two main clients, two products we are building end-to-end - the software they sell to their customers. No pitching, no growth-for-growth's-sake. Just code, shipped, week after week, for the same people who trusted us with the first commit. Both still here, nine years on.

For nine years, small was the only way that really made sense to us. Every model of growth we looked at had the same bloat baked in: layers, project managers, and the quiet death of taste. We never found one worth becoming. Then AI caught up to the way we already work, and a small studio could finally scale without turning into a worse version of itself. So here we are. Doors are open. Carefully.

Senior engineers, every one of them. The studio is rooted deep in Bulgaria's competitive-programming scene - one of the founders sits on the national IT olympiad jury. He judges, mentors, and meets the country's sharpest minds before they finish school. We watch them grow, and only bring them on once the production code on their CV is louder than the medals.

What we believe
Shape

Flat by design.

No PMs in the middle, no layers between intent and code. The shortest line between you and the keyboard is the only one we draw.

Stack

Any stack we need.

Modern tooling lets a senior engineer work fluently across languages and frameworks. So we pick the one that fits the problem - not the one that fits the résumé.

Tooling

AI in the loop, always.

Heavy AI tooling, every day. It's why one senior engineer ships like a small team - without cutting the corners that matter.

Time

Time is the currency.

Yours, ours, both. Most meetings exist because nobody's written the thing down yet. We write it down.

Speed

Bias for movement.

Decide fast, ship fast, watch what reality does, decide again. Stalemates are a tax we refuse to pay.

Experts

We tell you what we think.

If something in the plan won't work, we say so. If a feature isn't worth the build, we say so too. Honest answers save everyone time.

Why us in 2026

The car is fast. The cliff is faster.

Steve Jobs used to tell a story about a study he'd read. Of every species on the planet, the condor used the least energy to move a kilometer. Humans - walking - landed about a third of the way down the list. Unremarkable. Then someone put the same human on a bicycle, and the bicycle blew the condor away. That, Jobs said, is what a computer is. A bicycle for the mind.

Forty years on, the bicycle has an upgrade. AI isn't a faster bicycle - it's a car. Anyone with a prompt and an afternoon can cover ground that used to take a small team a week. We don't argue with the math. We use the same engines, every day. It's the reason one pod ships like a studio twice its size.

Here's the part nobody puts in the demo. Without an expert at the wheel, the same car that crosses the Amazon jungle in a day will drive you off a cliff in seconds - and ask no questions on the way down. Speed is the easy part. Steering is the work.

You can vibecode a prototype. A good one, even. An MVP that turns heads, lands a round, signs up its first real users - we've watched it work, we've helped people get there. What you cannot vibecode is the day after launch.

The model isn't the problem. It writes exactly what you ask. The problem is what you don't know to ask for. Retry backoff. Idempotency keys. The rate limit on the endpoint a bot will find first. Garbage in, garbage out. A faster model doesn't repeal it. It just writes the garbage faster.

That isn't a flaw in the tools. It's a flaw in the metaphor. A car is brilliant on a road. Production software is not a road. It's the jungle.

The work

Two products. Nine years. Still shipping.

What we ship are the products our clients sell. The tools for generating cash and getting things done. Below: the two we're still shipping today, plus a few we shipped before.

InfinityID

Sofia codes it. Three continents scan it.

InfinityID makes RFID solutions for the Industry 4.0 crowd. Plug-and-play, modular smart kit that tracks what's where. In real time, across factory floors, warehouses and retail shelves. Their customers run lines from Latin America to Europe to Singapore. The software those customers use is the one we develop every day.

We are the core dev team. Architecture, stack, every commit. The platform is multi-tenant by default. We ship it in two flavours - cloud and on-prem. Some clients want zero ops. Others want zero internet.

Every customer gets the modules their site actually needs. Logistics, retail, manufacturing - on Android, on the web. All configured from a console by InfinityID's team. Our integration layer supports any major RFID reader brand. Pick the hardware that fits the building, the budget, or the use case. The software just works.

INVENT

Inventory. Before lunch.

INVENT is a stand-alone, contactless inventory product. RFID tags on the assets. A handheld reader in your hand. An Android app counting fifty items in one sweep. No line of sight, no scanning one at a time, no afternoon lost to a clipboard.

Software's ours, end to end. Android in the field. Web for the asset register and reports. File-and-API bridges into whichever ERP the administration team is already using. The count that ended before lunch doesn't take the rest of the week to enter.

Multi-tenant by default. Cloud or on-prem, depending on where the data should be. Works nicely with the handheld and fixed readers. The kind of software you stop noticing - which, for inventory software, is the whole job.

From the archive

Work from the years before. Some still in production, some switched off. All of them ours.

    SpatialGo

    SpatialGo had one ambitious idea: throw real events inside virtual worlds. We built the core system for spinning up immersive event environments - wired straight into Z Reality Sphere's metaverse software.

    Then we built the other half - behaviour tracking inside the event, plus the analytics to tell organisers what actually happened in there. Where attendees lingered. What they ignored. The shape of attention, in three dimensions.

    Bibli

    Bibli wanted to drag library inventory out of the barcode era and into UHF RFID. The kind that reads a whole shelf in one sweep instead of one spine at a time.

    We built the full stack around that bet. A self-service kiosk with hardware support baked in. A hybrid mobile app so patrons could track what they'd borrowed. A desktop app for librarians managing the shelves. A web platform behind it all, handling licensing and setup. And SIP2 wired straight into whichever Library Management System the back office already ran - because nothing in that back office had to change.

    Gibo

    Gibo took on a corner of Italian hospitality nobody else was bothering with - gastronomias, the neighbourhood places that cook ready-to-eat meals from scratch every morning.

    We built the delivery stack from zero. A hybrid mobile app for the diners. An Android app for the kitchen, paired with mobile receipt printers. A web admin running the whole thing in the background. The food got there on time.

  4. 06

    sEat

    sEat was Gibo, pointed at football stadiums. Same delivery stack underneath. Re-engineered for forty thousand phones at half-time and the local cell tower in a temporary breakdown.

    We rewrote the data layer to take a punch. Resilient sync and offline-capable order flow. Order from your seat, walk to pickup, eat before the game resumes.

  5. 07

    Reality+

    Reality+ was the first commit we ever shipped - and one of the first AR apps to come out of Bulgaria. The idea: scan a magazine page, watch the page wake up.

    Native iOS. Native Android. Web admin where the people making the print campaigns wired up which physical page triggered which digital experience. For a first commit, we picked an interesting hill.

    Sozialdynamik

    Sozialdynamik is an online academy for the German-speaking world. The subject: relationships, and how to make them work - with partners, with family, with colleagues.

    Built on HubSpot CMS. Fully custom theme on top. The marketing team gets every HubSpot tool. The site gets none of the HubSpot look.

FAQ

Common questions. Uncommon answers.

The questions that come up before signing, during the build, and occasionally at 11pm on a Thursday. Same answers either way - plain English, no asterisks.

One call. That's the funnel.

Thirty minutes with a founder. No sales team, no pitch deck, no follow-up sequence. If the pod fits, you sign - and meet the engineers the same week.
