Two brothers, an in-house team, and a build log that starts in 2021.
Code2b is an AI automation studio run by brothers Aleksandar and Dusan Janca out of Athens, Greece. Alex leads engineering. Dusan runs operations and the client side. Both of us personally meet and scope every client, and our own team of 5+ experienced developers builds every system. Nothing is outsourced, and you own the IP.

The build log · 2021 to now
Five years, kept as a running log.
The history of the studio, written the way we keep everything else: dated entries, one artifact each, and only the numbers that survived contact with production.

LOG-01
Full-stack from day one
Before the studio had a name, the work was already end to end: web apps, products, dashboards, and the data systems behind them, designed, built, and shipped whole. That range is still the foundation of everything below.

Large-scale data engineering
The work deepens into serious data: we design and run a hotel-rate collection engine for a client platform, reading rates around the clock in markets we had never set foot in.

LOG-03
Code2b gets its name. The automation years begin.
The brothers make it official: a studio in Athens. The focus shifts to automation: workflows wired across the tools businesses already run, shipped on a fixed scope and a fixed fee.

Automation across 12+ industries
Invoices, bookings, back offices, outbound engines. The system count climbs, the patterns harden, and our cold outreach settles at a number most agencies never see.

The AI product year
We ship enrichabl, our own lead-enrichment platform, because the tool we wanted did not exist. And the AI reception fleet answers for dentists, barbershops, and nail salons across Greece, every call logged, a human looped in on the judgment calls.

Everything above is still running. Full stack, data, automation, and AI under one roof: the same two founders scope every build, the same in-house team ships it, and the log keeps appending.

Time handed back, by industry.
Most of our clients are under NDA, so the names stay out. The numbers do not: each line is measured on a system running in production.

Six of the workflows we run, with the time each gives back. Measured on live systems, not projected.
Two brothers, two builders, one in-house team.
Alex architects every system. Dusan runs the operation and the client relationships around it. Both sit in your first meeting, both scope the build, and our own team of 5+ experienced developers ships alongside them. No account managers, no handoffs.

Focus · Engineering and architecture
Alex leads the technical side of Code2b. He has shipped automation across more than a dozen industries, from invoice reconciliation to document-processing agents, and built enrichabl, our own lead-enrichment platform, along the way. He sets the architecture for every build, and our in-house team ships it to run reliably in production, not as a one-off demo.
Before anything gets built, Alex and Dusan sit with you to learn how your business actually works and where the hours go. From there Alex designs the agents, the integrations with n8n and the Claude API, and the Go and Python services underneath, and the team builds it alongside him. He stays close to it after launch too, because the people who build your system are the ones who keep it healthy.

Ops & clients02 · Co-founder
Dusan Dimitris Janca
Co-founder & COO · Operations & client delivery
Focus · Operations, client delivery, and growth
Dusan runs the operations side of every project. He sits in your first meeting alongside Alex, scopes the build, and stays your contact from that call through go-live and after. Between calls he sits between you and the developers: he turns what you need into what gets built, keeps timelines honest, and checks the work before it reaches you.
He is a builder too. The growth engine that fills our pipeline and our clients' pipelines is his own build, and he runs it in production every day. That daily building is what lets him talk with the developers in their own language, so nothing gets lost between your call and the code.
