Larsen Code Labs is a Phoenix, Arizona software engineering company that designs custom websites, builds custom software and mobile apps, and sets up AI automation for small and mid-sized Valley businesses. Everything is built in-house — no offshoring, no account managers, and direct access to the engineers building it — with real pricing published up front (projects from $2,500) and a fixed-price quote before any work begins.
You didn't start your business to babysit software.
Most Valley owners we meet are stuck on one of these three. Usually all three at once.
Your website works against you
It's slow, dated, or a pain to change without paying someone. Customers judge your business by it before they ever pick up the phone.
Your team runs on copy-paste
The same records and invoices get moved by hand between four tools that don't talk to each other. It's slow, it breaks, and it lives in one person's head.
AI could help — but where do you start?
Everyone's talking about it. Nobody's shown you what it actually does for your business, safely, without your data leaking into a public chatbot.
We fix all three — with software that fits how you already work, priced up front, built right here in the Valley.
One local team for the whole stack.
The site your customers see, the software your team runs on, and the automation that gives you your time back — all from one team in Phoenix.

Price your build the way we price it.
Our published ranges are wide because a handful of decisions determine where a project lands inside them. Answer those decisions here and the range narrows — same rate card we quote from, before you ever talk to us.
Published range for this project type: $5,000–$15,000 · see the cost guide
- Nothing unusual selected — this lands at the bottom of the published band.
Full design, CMS (WordPress or custom), local SEO foundations, and training. The most common build we do.
Get this quoted for free →A ballpark from our published rate card, with our standard 20% estimate buffer already in it — not a binding quote. Your real number comes in writing after a free consult.
Every range above is built from that rate. A tight, well-defined job lands near the bottom of its band; the top is a large build with integrations, data migration, and multiple user roles. Either way you get one fixed number in writing before anything starts.
The AI agent was directly linked to a 10% increase in conversions.
Larsen Code Labs' project management was impeccable. They delivered ahead of schedule and started as soon as the deposit was cleared. The team was approachable yet professional.
One engagement, one client, published somewhere we can't edit it. That's the whole of our third-party proof so far — and we'd rather show you the one real thing than pad this page with stock logos and testimonials nobody can check. The prices below are the ones they paid.
Most Phoenix agencies hide their prices. We publish ours.
You deserve to know roughly what something costs before you get on a call. Here's where our work actually lands.

You'll work directly with the engineers building your software.
Larsen Code Labs is led by Michael David Larsen, Lead Engineer & CTO — a software engineer with a background in corporate IT administration, which mostly shows up as caring more than average about what a system costs to run after it ships. The company was incorporated in Phoenix in April 2026.
When you hire us you are not handed to an account manager, and the work is not passed to an offshore team. You talk to the engineers building your project, start to finish. That is the whole point of the company.
Same standard on every project: web design for Valley businesses, custom software, and AI automation — hand-engineered in Arizona, with your name on the invoice and our name on the code.
The questions Valley owners actually ask.

Larsen Code Labs is a Phoenix, Arizona software engineering company that designs custom websites, builds custom software and mobile apps, and sets up AI automation for small and mid-sized businesses across the Phoenix Valley. Every project is built in-house, with no offshore handoffs and direct access to the engineers building it, plus pricing published up front and a fixed-price quote before work starts.

Which Phoenix Valley cities do you serve?
Larsen Code Labs serves the entire Phoenix Valley, including Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, and Glendale, working fully remotely from its Phoenix, Arizona headquarters — remote is how the company works, not a limit on who it serves.
Do you outsource or offshore the work?
No. Every line of code is written in-house in Arizona, with no offshore handoffs and no account managers between you and the engineers building your project.
Is my data safe when you build AI automation?
Yes. AI automation runs through private, secure endpoints with zero-data-retention agreements, so your business data is never used to train public AI models.
