Warsaw AI engineering studio · Available now

AI built for
your business.

Two senior engineers who get close to your problem and stay there until it's solved. No account managers, no bloat, no off-the-shelf models dressed up as solutions.

Why are we
'NextDoor'?

Because proximity means something. We're a two-person studio — when you work with us, you get both engineers, from kickoff to deployment, with no account manager in between.

But there's a second meaning: we can run AI literally next door to your data. Deployed on your own servers, using open-source models, with no data ever leaving your infrastructure. The name is the promise.

Everything we build is tested, documented, and deployed on your infrastructure — not a proof of concept you'll need to rebuild. We work in Polish and English and handle end-to-end: design, build, infrastructure, handover.

🔒

Your data never leaves

We deploy open-source models on your own servers — Bielik, Llama, DeepSeek, Qwen and others. No external API calls, no data residency risk. Built-in GDPR compliance for regulated industries.

📌

You talk to the engineers

No account managers, no ticket queues. Direct Slack or email to the people actually building — both of us, on every project, every week.

🎯

You understand what we built

We scope, build, and hand over. No subscription, no SaaS seat, no lock-in. You get code you understand and infrastructure you control.

Process

How we work

Three stages, no surprises. We keep the process lightweight so the energy goes into building.

01 — UNDERSTAND

We learn your business first

Before writing a line of code we map your workflow, data, and constraints. Most AI projects fail here — not in the model.

02 — BUILD

Tight scope. No bloat.

We build the smallest thing that actually solves the problem, with weekly demos so you see progress and can steer early.

03 — SHIP

Deployed and documented

We handle cloud deployment, write the handover docs, and stay available for the first weeks post-launch.

The team

Two engineers.
Zero middlemen.

You'll work directly with the people who build your product — start to finish.

PROJECT 01

Immacu — AI Admissions Assistant

Universities spend over 90 minutes reviewing each applicant manually — combing through documents, cross-referencing criteria, and updating records by hand. We built a platform that does this automatically: reads applications, extracts what matters, and lets admissions staff query the entire pool in plain English.

Taskify — AI Math Tutor

Private tutors are expensive and most homework tools only check final answers. In 8 hours at the AI Tinkerers × Google DeepMind Hackathon we built a voice-powered AI tutor: five specialised agents handle research, answer verification, and task creation, while a voice AI guides students through exercises on an interactive canvas — catching wrong reasoning mid-solution, not just wrong final answers.

Solvemed — Custom Research Tooling

A healthtech startup — working with researchers from Stanford, Harvard, Oxford, and Cambridge — was paying $20,000/year for a generic video labelling platform that only half-fit their needs. We replaced it with a custom tool built around their exact workflow, at zero recurring cost.

PROJECT 04

ZANT — Benefits Navigator

Navigating Polish social insurance (ZUS) after a workplace accident means deciphering dense legal forms and eligibility rules — alone. We built an AI that guides self-employed individuals through the process step by step: asks the right questions, checks eligibility, and explains what to file and why.

Document Intelligence — Bayer

Large enterprises sit on vast archives of documents that no one has capacity to review. We built an AI system that understands, queries, and reasons over complex document corpora — turning static files into an intelligent knowledge layer that answers questions and surfaces risk on demand.

PROJECT 06

NDA Sanity Check

Reviewing an NDA shouldn't require a lawyer on retainer. We built a web app that reads your agreement, flags unusual clauses, and summarises what you're actually signing — in plain language, in seconds. Built and deployed to production; presented at MIM UW × IBM conference.
