An engineering studio for hard problems

We solve hard problems AI, mathematics, engineering.

Bring the problem, not a finished spec. We scope it and its economics, pick the best fit — AI, an algorithm, an ERP or a mix — and take it to production. We do more than AI, and we say plainly where it pays off and where it does not.

Our own products in productionFormal proofs, not promises
04More than automation

When a ready-made tool cannot solve it, we go deeper.

Automation takes an existing tool and wires it in. Some tasks resist that — they need a bespoke algorithm, an honest numerical base or genuine research. Our moat is a technology base we build, not just other people’s APIs called for you. And we prove it, not claim it.

Our own numerical base

Balansis — a library that stays stable where ordinary arithmetic breaks. Not "we apply AI" but "we build the foundation under it".

73 theorems formally proved, 0 unproven assumptions (Lean4).

An honest metric, not "seems to work"

Every model is compared against a naive baseline. If it does not beat it, it is not needed. A negative result is reported, not hidden.

The same principle runs on our service pages, not just the showcase.

Reproducibility as an engineering norm

Our research systems are deterministic: same input, same result, byte for byte. That is what separates engineering from a demo.

A replay reproduces the exact run hash (Agent Native Universe).

From paper to service

We walk the whole path — framing, research, prototype, production. Our own models and libraries, not a retelling of someone else’s.

From mathematical theory to a verifiable library.

07Case studies

What we built. And what we could measure.

Contracted pilots, systems in operation and prototypes tested on real data. No client names — the industry, the task and figures backed by project artefacts.

06Evidence, not slides

We show how systems behave, not what we promise.

Behind the words is something you can open and check: reproducible runs, formal proofs and open source where possible.

03Ecosystem

We do not talk about AI we live in it

Behind the consulting are our own products and libraries. Some run in production with real users, some are open source, some are still research. Clients get engineers who fix their own systems daily, not a slide about experience.

StudyNinja

in production

Learning platform

The product where our technology lives in production

A learning platform for school students: a subject knowledge graph, gap diagnostics and next-step selection. This is where our research meets real users instead of demos.

studyninja.ru

KnowledgeBase AI

in production

Knowledge platform

Knowledge graphs and semantic retrieval as a separate layer

An engine that turns documents and a domain into a connected model: entities, relations, semantic search and provenance. It lives apart from any single product and is reused across projects.

Agent Native Universe

open source

Agent runtime, open source

An environment where agents negotiate, pay and reach agreement

A runtime for self-organizing agents: relationship negotiation, a resource economy, byzantine agreement between nodes and recursive organization into groups. MIT-licensed — download it and check.

research programme

MagicBrain

research

Neural core

Our own research line in brain-like networks

A research core: spiking networks, local learning, grown rather than hand-designed structure. Parts of it are in patent preparation, so publicly we speak of purpose and observable properties.

Balansis

research

Numerical foundation

Arithmetic that holds where ordinary arithmetic breaks

A computation library designed so that division by zero, overflow and precision loss do not take the pipeline down. A foundation under the other layers; the mechanism is in patent preparation.

UWT

research

Research track

Theory taken all the way to publication

A separate research line with an experiment registry, tests and a prepared preprint package. It sets the bar: a claim that cannot be checked does not ship.

08How we ship

A process with no wasted motion.

  1. 01

    Discover

    Deep immersion into your domain, constraints and data. We ask until the problem is sharp.

  2. 02

    Architect

    Systems design first — models, interfaces, failure modes. The blueprint before the build.

  3. 03

    Build

    Small senior team, fast iterations, working software every week. No theatre.

  4. 04

    Verify

    Evaluation harnesses, adversarial testing, load and safety checks — before your users do.

  5. 05

    Evolve

    Ship, observe, improve. Systems that learn — and a team that stays accountable.

09Why XTeam

The unfair advantage is the team.

Elite by default

A small team of people who would be the strongest engineer in most rooms.

Research-grade rigor

Claims are tested, numbers are measured, and “it seems to work” is not a status.

Speed with safety

We move fast because the guardrails are engineered, not improvised.

Human + AI, natively

Agentic workflows multiply every engineer. You get the output of a department.

We partner with founders, labs and enterprises across education, research and deep technology.

EdTechDeep TechResearch LabsSaaSScienceAI Platforms

Client list under NDA — references available on request.

They think like researchers and ship like a product team. That combination is almost impossible to hire.

CTO — education platform

XTeam gave us the output of an entire data science department — and raised the bar for the rest of us.
