ENGINEERING STUDIO FOR AI & SOFTWARE THAT SHIPS TO PRODUCTION
We build the other kind. Engineering is our identity and AI our sharpest specialization, so what we ship keeps working after the meeting ends: under real users, real load, and real costs. Two founders. No layers. You own everything we build.
The expensive part is not the demo.
A demo works because everything it needs is present: its builder at the keyboard, friendly inputs, one user, and nothing at stake but applause.
Production is when they are gone. Users send input nobody imagined. A dependency fails on a Tuesday. Costs compound per request. Nobody notices until a customer does.
All software fails this way, and AI fails hardest: built for the demo, sold as if built for production. That is the gap. Companies pay twice, once for the demo and once to learn it cannot ship.
Codexyo exists for the part after the applause. The part where it has to hold.
Engineers first. Production AI is our specialization and our reputation. The engineering underneath is how it reaches production: real depth, not a menu.
Intelligent Systems
AI built to a production standard, not a demo: measured, monitored, cost-controlled, and built to hold under real users.
- LLM applications
- AI agents
- Computer vision
- Voice AI
- Applied ML & automation
Software Engineering
The systems intelligent features live inside, and the ones that never needed a model at all.
- Full-stack applications
- Backend platforms
- APIs & integrations
- Cloud architecture
- Data pipelines
Delivery & Scale
The unglamorous work that decides whether any of it survives production.
- DevOps & CI/CD
- Quality engineering
- Observability & monitoring
- Performance
- Maintenance & support
Backend, cloud, integrations, QA, or embedded engineers alongside the AI: that is already how we deliver. And if your problem does not need AI, we say so.
Production is a defined term here.
Everyone says production-grade. We wrote down what we mean and published it. Hold us to any line.
The definition: a system is in production when it survives four absences.
The absence of its builders
An engineer who has never met us can run, deploy, and change it from what we handed over. We test this before we leave: the Stranger Test.
The absence of well-behaved input
Malformed, hostile, or oversized input, including input written to manipulate a model, produces designed behavior.
The absence of the happy path
Every dependency has a plan for the day it fails. Every rollback is rehearsed, not assumed. A backup never restored is a hope.
The absence of attention
The system reports its own condition: correctness, cost, drift, and failure reach a named person before your customers.
The full document: twelve principles, nine gates, and the scorecard every system must pass before it ships, with or without a model inside. Versioned, public, and it includes the case against itself.
"They shipped in six weeks what our last vendor couldn't scope in six months. Rare mix of research depth and delivery discipline."
Daniel ReedCTO — SERIES B FINTECHSUPPORT AGENT SYSTEM · FOUNDER WORK, PRE-CODEXYOThe people you meet are the people who build.
Codexyo is two founders, by design. No bench to hand your project to, no juniors executing senior promises, no account manager between you and the person writing the architecture.
Faisal Afzal
Runs the first conversations and the scoping: the questions that decide whether a system should exist at all. Translates the business problem before it becomes architecture, and stays until handover.
You meet both of us on the first call, and you still talk to both of us in the last week.
Look us up before you contact us. We prefer clients who check.
The work, with the numbers attached
A short list, on purpose. Every entry is real and checkable: a public repository or a live product. Work the founders shipped before Codexyo is labeled that way.

Every case study is revisited annually. If a system is retired or a number changes, the write-up says so.
What our clients say.
The claims copilot paid for itself inside a quarter. Handle time fell 38% and our adjusters stopped drowning in PDFs.
71% of tickets resolve before a human sees them. CSAT went up, not down. We plan headcount differently now.
They told us plainly the feature we came in asking for wasn't worth building. That honesty is exactly why we came back for the next one.

22,000 documents a day, zero manual touch. The pipeline Codexyo built quietly became our operations backbone.
They shipped in six weeks what our last vendor couldn't scope in six months. A rare mix of research depth and delivery discipline.
The system has run in production untouched for months, and our own team operates it from the runbooks they left. That is the whole review.

Built so you are never trapped. Including by us.
Outcome-first, flexible in shape: we own a deliverable end to end, start with an architecture review or advisory, or embed engineers with your team. Whatever the shape, the way we work is the same.
- Diagnosis before construction. The first conversation examines the problem, not the contract. “Do not build this” and “you do not need AI” are real outcomes.
- Bounded scope, in writing. What we build, what we do not, what it costs, and what done means, agreed before work starts. Changes are negotiated openly, never absorbed silently.
- Working software, weekly. Progress is the system running in front of you. If a week produced nothing you can see, we say that, and why.
- Your name on everything. Repositories in your organization, infrastructure in your accounts, credentials in your control. You own the system at every moment.
- Handover is scheduled, not hoped for. Documentation, runbooks, recorded knowledge transfer, and the Stranger Test: an engineer who has never met us runs the system from what we left. We are easy to leave. That is why clients stay.
- The gates are visible. Before anything ships, it is graded against the Production Standard scorecard, and you see the grades and the evidence. Production-ready is a document, not an announcement.
Start with the Production Readiness Sprint
Ten working days. Fixed fee. One question answered with evidence: should this system be built, and what will it take?
Bring an idea, a stalled prototype, an architecture decision, or a system that worries you. You leave owning six things: a written verdict, a production scorecard, an evaluation baseline, an architecture blueprint, a risk register, and a build plan any competent team can execute.
Thirty minutes. We check fit before taking payment. Some intake calls end with us telling you not to buy the sprint.
TERMS, STATED PLAINLY
- Fixed fee, agreed before you say yes. No hourly meter.
- Any build that follows is priced to your problem, not a rate card. Tight on budget or time? Tell us early: we shape the work to fit, or say honestly that we cannot.
- The Verdict contains no proposal. A bid for the build comes separately, and only if you ask.
- The sprint fee is not credited against a build. The sprint is work, priced as work; a credit would make it a sales cost, and then you could not trust the Verdict.
- At most two sprints a month, both founders on every one. If we are full, you wait or we refer you. We do not stretch.
The questions you are already asking.
The questions you would ask across the table, answered here.
What if your pricing doesn't fit our budget?
Don't let the budget stop the conversation.
Tell us what you're working with: we can reduce the scope, deliver in phases, or work alongside your team.
We're here to solve the problem, not sell the biggest project. If we can't do work we'd put our name on within your budget, we'll say so and recommend a better path.
Will our idea and data remain confidential?
Yes, by default. We sign your NDA before technical discussions, or a mutual one. Code, credentials, data, and business information are confidential from day one, and nothing appears in our case studies without your written permission. We do not need your project to be public to prove we built it.
Do you offer ongoing support?
Yes. Every engagement includes written support terms, response times, and escalation paths, agreed before work begins. If you need specific coverage windows or a standing arrangement, we set it up at the start, not after launch, and we never promise coverage we cannot sustain. Every system also ships operable by your own team, so staying with us is a choice, never a dependency.
Are you the cheapest option?
No. If you want the lowest bid, we're probably not the right fit. The better comparison is the cost of a system that works, lasts, and your team can own. That's why we start with a fixed-price sprint: in ten days you know whether we're the right partner, before any larger build.
Won't the sprint just conclude we should hire you?
Four mechanisms say otherwise. The Verdict contains no pitch. The Build Plan must work for any competent team, or it fails our own review. The fee is not credited against a build. And we track our verdicts: if every sprint ended in “build it, with us”, the product would be broken, and our own metrics say so in writing.
Who owns the code and intellectual property?
You do. Unless agreed otherwise in writing before work begins, everything built for your project is yours: source code, documentation, deployment assets, and deliverables. Repositories live in your organization from the first commit, so ownership is the default, not a handover event.
Can you work with our internal team?
Yes. Most clients have us own a defined outcome, and we recommend that when it fits. We also work alongside internal teams: as technical partners, embedded engineers, or hourly when that genuinely serves the project. We recommend the model that gives your system the best chance in production, not the easiest one to sell.
You're a new company.
As a firm, yes: founded in 2026. The work we point to is real and labeled with where it came from, including what the founders shipped before Codexyo. Our individual histories are public. Check them. We will never inflate the firm to look older or larger than it is.
Who should not hire you?
Anyone shopping for the lowest bid. Anyone who wants a demo for a board deck and does not care if it ships. Anyone offering equity instead of budget. If that is you, we part here as friends.
You're two people. What happens if one of you gets hit by a bus?
Every system we ship is built to survive our absence: client-owned repositories, documentation, runbooks, and a handover tested against a stranger. That is Part 4 of the Production Standard, and it exists because we are two people. A firm our size cannot afford to make you dependent on us, so we engineered the opposite.
Ten days. One answer.
Yours either way.
The Production Readiness Sprint answers whether to build it before you pay to build it. Fixed fee, six deliverables, all yours whoever builds next. Even if the answer is do not build. Especially then.
Not ready to talk? Read the Production Standard. It does its job without us in the room.
Tell us what you're building.
The first conversation is thirty minutes, free, and diagnostic. Bring a system in mind, a stalled prototype, or a problem you can't quite place yet. We reply within one business day.
- 01We read it ourselves. Both founders, no queue in between.
- 02If it's a fit, we book a thirty-minute call to understand the problem.
- 03If it isn't, we say so, and often point you somewhere better.
