We build custom platforms for how your business actually works.
Off-the-shelf software makes you bend to fit it. We build tools that fit you instead. Real, working platforms and apps that we have already shipped.

Real products, live in the wild
What we build
Whether you need a whole platform or one tool that stops the bleeding, we start with the problem, not the tech.
Custom Platforms
Full platforms that run a business or an organization. Members, billing, scheduling, reporting, all in one place instead of ten separate tools.
Business Apps
Focused apps that solve one real problem well. Check-in systems, internal tools, customer-facing portals. Simple enough that people actually use them.
Workflow Automation
The repetitive work that eats your week gets handed to software. Data entry, approvals, and hand-offs that used to sit in an inbox.
AP & Finance Tools
Nine years in accounting and FP&A means we speak finance. Accounts payable, expense tracking, and reporting built by people who have done the job.
Work we have shipped
Not mockups or concept slides. These are real products people use right now.

ChamberPulse
An all-in-one platform for Chambers of Commerce.
ChamberPulse is a white-label platform I built to help Chambers of Commerce run the whole operation in one place. Members, events, billing, and communication used to live in a pile of disconnected tools. Now they live under one roof.

The Center Check-In System
A simple, fast check-in system built for real day-to-day use.
A check-in system built to make signing people in quick and painless. The goal was simple: replace paper sign-in sheets and clunky spreadsheets with something anyone can use in a few taps.

SimplyExpensed
Expense and mileage tracking for people who hate bookkeeping.
SimplyExpensed is expense tracking built for freelancers, contractors, and small businesses. Snap a receipt, let it categorize the expense, track your miles, and pull a tax-ready report when you need it. Free to start.
How we work together
No massive all-at-once transformation required. We crawl, walk, then run.
Workflow Analysis
We start by mapping how the work actually happens today, not how it is supposed to happen. That is where the real opportunities hide.
Build the First Win
Start small, win early. We build the piece that solves your biggest headache first, so you see something working instead of a six-month invoice.
Launch and Grow
We put it in front of real users, fix what needs fixing, and expand from there. Momentum you can actually see.

Why work with us
That AI Guy LLC is Bradley Gustafson. We spent nine years in accounting and FP&A before going all in on building software. That mix matters. We understand the numbers side of a business and we can build the tool that fixes it.
We are not an agency that hands you off to a junior team. You work directly with the person actually building your product. That means straight answers, realistic timelines, and no jargon for the sake of sounding smart.
Our approach is people-first. The best software is the kind your team forgets they are even using because it just works. That is the bar.
Also in the toolkit
Beyond building platforms, we help teams clean up and automate the work they already do.
AP Automation
Invoices, approvals, and payments that move on their own instead of sitting in a pile. Built by someone who actually worked in accounting.
Learn moreProcess Optimization
Before automating anything, it helps to fix the process itself. We map the messy version, find the bottleneck, and clean it up.
