About Root & Margin
Root & Margin helps owner-operated small businesses in Knoxville get found online — and sell when the business is ready. Productized packages, clear boundaries, fast delivery. Veteran-owned and operated.
I’m Sean Hagstrom — veteran, solo founder, and software builder. I built Root & Margin the same way I help clients: as a Knoxville sole proprietor who needed to look credible, get found, and invoice without chaos. I recently went through the EIN, county license, business bank, and professional email setup myself, so I know what it feels like to go from side project to real business.
I focus on the online half of that journey — a professional site that helps customers find you and contact you, or a focused shop when you need to take payments. Not an agency with ten service lines. Not custom software. Not business formation consulting.
