Everything is built in-house by founder and lead engineer Michael Larsen — no offshoring, no account managers — 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 studio 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 under one roof in Phoenix.

You'll work directly with the person writing your code.
I'm Michael Larsen, founder and lead engineer. I've been writing software for 18 years and incorporated Larsen Code Labs right here in Phoenix. When you hire us, you're not handed to an account manager or an offshore team — you talk to me, and I build it. That's the whole point.
Same standard on every project: web design for Valley businesses, custom software, and AI automation — hand-engineered, locally, with your name on the invoice and mine on the code.
The questions Valley owners actually ask.
What does Larsen Code Labs do?
We're a Phoenix, Arizona software studio. We design custom websites, build custom software and mobile apps, and set up AI automation for small and mid-sized businesses across the Valley — all built in-house with pricing published up front.
How much does a project cost?
Real ranges, published openly: landing pages from $2,500, business websites $5K–$15K, online stores $9K–$40K, custom web apps $18K–$90K, mobile MVPs from $12K, AI audits $3K–$8K, and workflow automation $5K–$25K. The typical rate is $150/hr with a $2,500 minimum, and you get a fixed price in writing before work starts.
Do you work with small businesses, or just big ones?
Small and mid-sized Valley businesses are exactly who we build for — contractors, medical and dental practices, real estate teams, retailers, and professional services firms. Our minimum engagement is $2,500.
Which Phoenix Valley cities do you serve?
The whole Valley — Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, and Glendale — with in-person meetings across the metro and remote collaboration anywhere in Arizona.
Do you really not outsource?
Correct. Every line of code is written in-house in Arizona by Michael. No offshore handoffs, no transient third-party networks, no account managers between you and the engineer.
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.
