Spring Hill Business Lab
What this is
A small room, a real build, a full day of help.
01
Hands-on, start to finish
One day. You're at the keyboard building your own app — guided from the first idea to the moment it goes live. No watching from the back row.
02
A curated local group
Capped at 15 Spring Hill business owners — B2B and consumer-facing alike. Small enough that you're never stuck, and you leave knowing the room.
03
Built for your business
You don't build a demo. You build the tool your business actually needs — with your services, your prices, your questions baked in.
The setup
You already know your business needs better tools.
You're the kind of owner who notices the gaps. The lead that never got followed up. The quote you meant to send. The same five questions you answer every single day. You've thought, more than once, "there should be a simple tool for this."
And every time, you hit the same wall: building it means hiring a developer, writing a spec you're not sure how to write, and spending a budget that's earmarked for things that already work. So the idea goes back in the drawer.
Here's the part worth saying plainly: the wall moved. The tools an owner can now build in an afternoon used to take a team a month. The only thing missing is a day to sit down and do it — with someone beside you the whole way.
The shift
In one guided day, you build the tool yourself —
and walk out with it live.
Not a slide deck about what's possible. Not homework to finish later. You sit down in the morning with an idea for your business, and you leave that evening with a working app that's actually running — built by you, owned by you, ready to put in front of customers.
Is this you?
"But I'm not technical."
Good. This day was built for exactly that person — the owner who runs a real business and has never written a line of code, and doesn't want to start now.
You won't be left staring at a blank screen. Guidance is there the entire day. The moment you get stuck, someone is right there to get you moving again. Nobody walks out half-finished.
- No coding experience required — none.
- Help is in the room all day — you're never stuck for long.
- Prep instructions arrive by email beforehand, so day one is all building.
- If you can run your business, you can build this.
What you'll build
Start with a proven idea — or bring your own.
These are popular starting points, not a fixed menu. Whatever you decide to build, it'll tackle at least one headache you're dealing with right now — or hand back time you're losing every week.
Instant Quote Calculator
Customers enter a few details and get a ballpark price on the spot — so the ready-to-buy ones raise their hand instead of bouncing.
AI FAQ Assistant
An AI chatbot trained on your business that answers your customers' most common questions — day or night, in your voice.
Review Showcase & Request Page
Puts your best reviews front and center and makes it effortless for happy customers to leave the next one.
Spin-to-Win Promo
A spin-the-wheel discount that turns a casual visitor into an email subscriber and a first order — great for retail, food, and salons.

Where this came from
Why Level-Up Day exists.
I've been building custom systems and apps for decades — more than 150 of them to date. For most of that time, bringing an idea to life meant hiring developers, writing specs, and waiting weeks to see it work.
Then AI changed the math. Today I can take an idea and ship a working tool in a fraction of the time — sometimes in under an hour — without writing the code myself. The first time it really clicked, the thought was immediate: if I can do this with AI without knowing how to code, every business owner around me can too.
That's the whole reason Level-Up Day exists. One of my missions is to make Spring Hill a true Business Innovation Hub — not by talking about technology, but by putting it directly in the hands of the owners who run this town. This is me handing it to you, for a day, in person.
“If I can build this with AI without writing a line of code, so can you. That's the whole idea.” — Rengie Mendoza
Does it actually work?
I'm not teaching this from theory. I've shipped 150+ of these.
For decades I've built custom apps that solve one specific, real problem at a time — over 150 to date, for every kind of local business. Not demos. Tools owners use every day. A few of them:
Scheduling tool
In-home music studio
Booking and lessons handled without the back-and-forth.
Custom pricing tool
Events company
Complex packages priced in seconds, not spreadsheets.
Real-time estimator
Limo company
Instant ride quotes the moment a customer asks.
ROI tool
Chamber of commerce
Members see the value of membership in real numbers.
See the pattern? A scheduler, a price calculator, an instant estimator, an ROI tool — these are the same building blocks you'll work from at Level-Up Day. The approach is proven 150 times over. The only new part is that this time, you build yours — with me right beside you.
“TODO (optional): real builder testimonial — what they built and what it did for their business.”
“TODO (optional): a quote from a non-technical owner who surprised themselves.”
What you walk away with
More than a finished app.
You won't walk out an engineer — and you don't need to. You'll walk out having taken something from a rough idea to a live, working tool with your own hands. That single skill — knowing you can actually ship it — is what makes the next build faster, and the one after that.
A working app you own
Live and running on your accounts — not a prototype, not a maybe. Yours to keep, use, and change.
The confidence to keep building
Once you've shipped one, the next idea stops feeling impossible. You'll know how the pieces fit.
A room of local owners
Nineteen other Spring Hill business owners who get it — relationships that outlast the day itself.
Who you become
You walk in an owner who buys tools.
You walk out one who builds them.
That's the real shift. Not a one-time app, but a new answer to "there should be a tool for this" — because now there's a person who can build it. You.

Why now
The "I'll get to it someday" window just closed.
For years, building your own tools meant a developer and a budget. That's no longer true — and the owners who notice first are the ones who pull ahead. The only question is whether you build yours with a guide in the room, or keep meaning to figure it out alone.
The moment
The tools an owner can build in a day now do what used to take a team a month. That window is open — early movers win.
The room
15 seats, one curated cohort. When they're claimed, that's it — no overflow, no livestream, no replay.
The date
One day — Aug 11, 2026. Miss it and the next one is a long way off.
Why it's worth it
Honest math.
Hire someone to build just one of these apps and you're easily into the hundreds — often a good deal more — before it's even tailored to your business. So run your own numbers:
Chamber / SHBL member?
$500$5,000
Hire it out
$3,600
Build it yourself
$149
A directional estimate you can adjust — not a guarantee. And you walk away with the skill to build the next one, plus a full day of guidance and meals.
Why listen to Rengie
The person beside you all day has done this — and his own community trusts him to.
Rengie Mendoza
Spring Hill Chamber 2025 Man of the Year & Innovation Partner · Founder, RenzaGroup
Let's be clear about one thing: Rengie doesn't write code. He doesn't speak "developer," and he never learned to — on purpose. His skill is a different one, and it's the one that matters here: he knows what today's technology actually makes possible, and he designs tools and apps around that — always aimed at solving a real business problem, never just building a shiny object that looks impressive and does nothing. The Spring Hill Chamber named him 2025 Man of the Year and Innovation Partner for exactly this.
That's the whole point. He's not here to turn you into an engineer — he's here to show you how he's turned 150+ ideas into working tools without writing a single line of code. If he can build it without speaking the language, so can you. Level-Up Day is that proof, put in a room — with him at your shoulder the whole time.
