The most seasoned dev on the team — finally, on every team.

Axtar pulls up a chair next to Claude Code, Cursor and Codex — and tells them how this team actually does things. Rules extracted from your code. Served at write-time. Drift caught before review.

The codebase is drifting. Nobody is steering.

Agents ship code at frontier-model speed. Your team's standards never had a chance to keep up.

  1. 01

    Abstraction drift

    Agents invent layers nobody asked for. The codebase grows new vocabulary every week.

  2. 02

    Rewrite tax

    The same module gets rebuilt three times a quarter. Each agent rediscovers the same dead ends.

  3. 03

    Feature cost ↑

    Shipping speed flat. Complexity compounding. The unit cost of "one feature" creeps up every sprint.

  4. 04

    Taste roulette

    Five engineers, five conventions, no winner. PRs argue about the same things they argued about last month.

  5. 05

    Cost · cost · cost

    Inference bills, review queues, rework cycles, retention damage. Drift compounds in every column of the P&L.

Now there is someone who tells agents how to do it.

— AXTAR

W H A T   I T   I S

A rules engine for coding agents.

Axtar knows the rules. Knows how the system should be engineered. Knows what to avoid. Pulls up a chair next to Claude, Cursor, Codex — and tells them how this team actually does things.

# SESSION.LOG LIVE EXCHANGE
claude_code: "join between users and billing tables added to user_service."
axtar: "service boundary violation. billing data lives in billing_service. rule: arch.service_boundaries (severity: block)."
claude_code: "...moving query to billing read model."
review_cycle 3.4s rule_id arch.service_boundaries drift_caught 1

Plugs into the agent loop. Provides advice and short review cycles to ensure architecture is followed, business is not violated and code quality holds. Plus an extraction layer that reasons rules out of the source, review history, docs and other artifacts your team has already produced.

Same agents. Different output.

The model doesn't change. The taste of the codebase does.

STRONG MODELS

Higher ceiling, every time.

Claude and Codex stop second-guessing your team's taste. Code lands like a senior wrote it, first try. No more re-prompting to coax the right shape out of a frontier model.

WEAK MODELS

Cheap models match expensive ones.

Smaller models routed through Axtar produce outputs comparable to frontier models — for a fraction of the inference bill. Your routing strategy stops being a tradeoff.

EVERY MODEL

Agents do what you want, not what they know.

No more generic syntax polluting the codebase. No more invented layers. Your team's rules — applied at write-time, not caught later in review.

ENGINEERING

Fewer roundtrips between engineer and agent. Output lands precise on the first pass — no re-prompt cycles to coax the right answer.

REVIEW

Less time spent in review. Rules become first-party citizens — enforced at write-time, not caught in PR comments.

One platform. Two faces.

The Rules Engine reads how your seniors build, stores it like code, streams the signal to anything else in your AI stack.
The Mentor sits beside Claude, Cursor and Codex — pairing on every line they write.

W H O   W E   A R E

Two architects who watched the craft start to fade — and decided to build the mentor that scales.

We've spent 31 years building software where standards aren't optional. For the last year, both of us have been deploying AI engineering inside live enterprises and watching standards decay under agent traffic in real time.

Konrad Szatan

13 years building high-throughput data platforms at Adform, Tink (acq. Visa) and Capital.com — environments where standards weren't optional. Co-founder of RentLink, an agentic AI rental management SaaS. Conference speaker and community builder on the JVM/Data circuit.

Dawid Kubicki

CO-FOUNDER · ARCHITECT · 18+ YRS

Dawid Kubicki

Tech Lead at Tink through the $2B Visa acquisition — regulated open banking, where the quality bar is set by regulators, not opinion. Before that, Allegro — largest EU marketplace. 18 years on backend architecture and technical leadership.

Apply to be a design partner.

Direct access to founders. We extract your rule set, deploy on your stack, and measure review-time and cost-per-PR with you. Limited slots — closing as we ship.

  • Direct line to Konrad & Dawid. Weekly working sessions with the founders — your reality lands in product directly, not through a queue.
  • Shape what we build. The rule packs, the workflows, the integrations we ship reflect what worked for your team first. You're at the table when we decide what's next.
  • Founding-member economics. Pricing locked in for the seed and Series A vintage. The terms we offer founding partners don't come back later.
  • A peer cohort of architects. Quarterly off-the-record roundtables with the other engineering teams running Axtar in production. Compare notes with people fighting the same fight.

No demo theatre. We reply from a real inbox, usually within 48h.
