Custom software and integrations in Greenville, South Carolina
Custom software and integrations for Greenville businesses. Built when off-the-shelf falls short.
Greenville at a glance
Built on manufacturing, growing on everything else.
Greenville County is home to more than 583,000 people and grew 11.0% between 2020 and 2025. BMW's plant just up I-85 in Spartanburg County is the largest BMW plant in the world, Michelin North America's headquarters sits right here in Greenville, and Prisma Health, the largest health system in South Carolina, is based here too. Underneath the big names, it's small firms doing the daily work: small businesses make up 99.4% of South Carolina's businesses and employ 42.9% of its workforce.

Where we work around Greenville
Greenville and the whole Upstate.
We work with businesses anywhere in Greenville County and across the Upstate, remotely and on site. Downtown Greenville's professional firms and restaurants, Mauldin's home services along I-385, Simpsonville's trades on the Golden Strip, Greer's automotive suppliers and logistics firms, Taylors' shops along Wade Hampton, and Travelers Rest's hospitality businesses at the Swamp Rabbit Trail. Spartanburg, Anderson, and everywhere along I-85 are in range too.

Examples
What's worth building first around Greenville.
These aren't a limit. They're the gaps we see costing real hours.
Manufacturing & automotive suppliers
Supplier portals, quoting tools fed by your real costs, and integrations between plant systems and the office, so an order's status is one lookup, not three calls.
Construction & trades
With 4,947 building permits issued in the county in 2025, builders need quoting and client-update tools that keep pace. We build the configurator, portal, or integration your current software can't give you.
Hospitality & food service
Booking and event tools that connect to your existing systems, and dashboards that show every location's numbers the same way, pulled live.
Professional services & engineering
Client portals for project documents and approvals, connected to your project system, so clients stop emailing for the file you already sent twice.
How it works
Start. Build. Stay.
Start
Every engagement starts with a diagnostic. We find the gap your current tools can't close, check honestly whether something off-the-shelf closes it, and put a dollar figure on building only what's missing. The Krastor Blueprint is the written plan that comes out of it: fixed fee, starting at $1,500, and yours to keep whether you hire us or not.
Build
We design and build the missing piece, in your name and on your accounts, and connect it to the systems it has to talk to. You see it working with your real data before it goes live, not in a slide deck.
Stay
We keep it running, check its work, and show you what it saved and what it earned. You own the tools, the data, and the code. No lock-in, no disappearing act.
Rules to know
AI and data rules in South Carolina.
We found no broad AI law or consumer-privacy law for South Carolina private businesses as of September 2026. Federal and industry rules still apply.
Keep sensitive customer data out of public AI tools unless your vendor contract covers it.
This is a plain-English summary, not legal advice.

Questions
Straight answers.
Do we own the code?
Yes. The tools, the data, and the code are yours, built in your name and on your accounts, and the software subscriptions go on your card, not ours. If you ever stop working with us, all of it stays with you. What you lose is us keeping it running.
How is this different from hiring a developer?
A developer builds what you spec. We start with the diagnostic, so what's built is tied to the work costing you the most, and we stay on to run and improve it. One team accountable for the whole thing, not a handoff.
Do you work with businesses in Greenville and the Upstate?
Yes. We serve Greenville and the whole Upstate now, remotely and on site. Our South Carolina rep is based in-state, and our founder is moving to Greenville.
What size business do you work with?
Businesses with roughly 10 to 250 employees. Big enough to have real repeat work worth automating, small enough that the owner or an ops lead can make the call.
How do we start?
With a free 30-minute diagnostic. Book it at cal.com/krastor/intro. We map your operation, name what's actually slowing it down, and send a written assessment whether you hire us or not.
