Hai. hi + AI

We seed software.

An AI-native studio. A human directs fleets of AI engines — Claude, Codex, Gemini and more — that build in parallel, resolving countless drafts into one shipped product. Proven before it reaches you.

Appaya is an AI-native studio. We don't rent you hours — we grow finished software. A human directs a fleet of AI engines that build in parallel, and every change is proven before it reaches you.

01 — Services

Four ways to grow
software with us.

Pick the shape of the engagement. The rigor underneath is the same on all four.

Ship

Fixed-scope build.

A defined outcome, quoted up front, delivered and proven — never billed by the hour. You know exactly what you get before we start.

  • A scoped spec & a fixed price
  • Working software, shipped and handed over
  • A proof receipt behind every change

How We scope it, build it across parallel lanes, and hand it over the moment the proof holds.

Embed

Fleet + director, in your team.

An AI agent fleet and a human director run your delivery from the inside — the throughput of many, the judgment of one.

  • A director embedded in your team
  • Parallel agent lanes on your backlog
  • Your rituals, your repo, our rigor

How We plug into your tools and move your roadmap — reviewed at every step, in your own workflow.

Rescue

Rebuild the AI slop.

Inherited a codebase an AI hallucinated into existence? We audit it, prove what's actually broken, and rebuild it correct.

  • An honest audit of what really works
  • A prioritised, evidence-backed fix plan
  • A rebuilt, reviewed foundation you can trust

How We drive the real product, surface the fabrications, and replace them with proven code.

Design

Design as a peer.

First-class product design — not a skin applied at the end. Taste is a feature, and we treat it like one.

  • Interface & interaction design
  • A coherent, reusable design language
  • Design shipped with the build, not after it

How Design and engineering move together, in the same lanes, held to the same bar.

02 — Why AI-native

One studio.
Endless builds.

A traditional shop sells you hours and one person's output. We sell you outcomes — a fleet's throughput, held to a reviewer's bar.

01

Throughput of many, judgment of one.

Agents do the volume across parallel lanes. A single human director sets the scope, steers each lane, and owns the call on what's good enough.

02

Provider-agnostic by design.

We're not married to one model. Work routes to whichever engine is best for the job — Claude, Codex, Gemini and more — and switches as they improve.

03

Order from many elements.

Countless drafts, one shipped result — resolved, aligned, real. That convergence, chaos into a clean formation, is the whole thesis of the studio.

04

Proof over promises.

Speed without proof is just fast slop. Nothing is "done" here without runtime evidence attached — and that receipt is yours to keep.

03 — How we build

The rigor that
makes AI delivery
trustworthy.

Speed without proof is just fast slop. Every change moves through five gates before it ever reaches you — no exceptions, no shortcuts.

  1. Gate 01

    Plan review

    Before a line of code, the approach is reviewed. A wrong plan caught here costs minutes — caught later, it costs the build.

  2. Gate 02

    Build with fleets

    Human-directed AI agents — Claude, Codex, Gemini — do the work in parallel lanes, each one scoped and steered by a person.

  3. Gate 03

    Headed-browser proof

    The change is driven in a real browser and screenshotted. We show the thing working — never assert it from a green checkmark.

  4. Gate 04

    Adversarial cross-engine review

    A different AI engine reviews the work adversarially — hunting failure modes, security holes, and quiet corruption the author would miss.

  5. Gate 05

    Anti-fabrication proof receipt

    "Done" only counts with runtime evidence attached. Claimed-but-unproven work is rejected, not shipped. That's the receipt you keep.

04 — Work

Our own products
are the portfolio.

No invented clients. No borrowed logos. The work is our own — real, modest, and true. Here's what we've built the Appaya way.

05 — How we work

Every change passes an adversarial cross-engine review before it ever reaches you. That's how we guarantee the quality.

The rigor isn't a promise on this page — it's a gate in the pipeline, and the proof ships with the work. Premium delivery, priced like it.

Fixed scope

A defined build for one price, agreed up front. Best when you want a clear outcome shipped and proven.

Retainer

A director plus their fleet on your roadmap, monthly. Best for continuous delivery inside your team.

Day rate

Focused senior time for an audit, a rescue, or a hard problem. Best when the scope is still forming.

06 — Questions

The honest
answers.

What does an engagement cost?

Ship builds are fixed-price, quoted after a short scoping call — you know the number before we start. Embed is a monthly rate for a director plus their fleet. No hourly meters, no surprise invoices.

Do AI agents write all the code?

Agents do the volume, working in parallel lanes. A human directs every lane, and no change ships until it passes review. Speed comes from the fleet; trust comes from the gate.

Who owns what you build?

You do. Full ownership of the code and the design on delivery — it's your product, not ours. We keep nothing but the lessons.

How is this different from a normal agency?

A traditional shop sells you hours and one person's throughput. We sell you outcomes, backed by a fleet's throughput and a reviewer's rigor — proven, not promised.

We already have an AI-generated mess. Can you help?

That's Rescue. We audit the codebase, show you exactly what's broken with evidence, and rebuild the broken parts correct — no hand-waving, no blame.

Who's behind Appaya

Appaya is founded and directed by Luke Czak — the human who scopes the work, steers the fleets, and signs off every build before it ships.

Luke is also available for select fractional and senior product & AI leadership engagements — details on his personal site.
