Quality America

What Quality America does

Quality America Inc. is a privately held, bootstrapped software and training company headquartered in Tucson, Arizona, operating continuously since 1982. The company builds Statistical Process Control (SPC) software and Lean Six Sigma training materials, founded and led by Paul Keller, who is also the author of multiple McGraw-Hill books including The Six Sigma Handbook (150,000+ copies sold) and SPC Demystified. Its installed base is described as 'tens of thousands of companies in over 25 countries.'

The product portfolio centers on SPC-PC IV Explorer, a Windows-based enterprise SPC application with optional Work Set View for real-time data entry ($1,495), an IIS-hosted Web Interface for browser access ($695 named-user annual), and an optional SQL Server back-end. It is complemented by QA-Calibrate (calibration management with optional 21 CFR Part 11 compliance, starting at $1,095) and two COM Add-ins to MS Excel — SPC IV Excel ($299) for core charting and Green Belt XL ($399) for DMAIC/Six Sigma project tools. Revenue is generated through perpetual desktop/network licenses (one-time), recurring web and training subscriptions, and book sales, with volume discounts at 2–9 and 10–29 user tiers. The company distributes through its own e-commerce storefront, inside sales reachable at [email protected], free 30-day software trials, web demonstrations, and a knowledge center for content marketing.

Go-to-market is a hybrid of enterprise field sales, inside sales, and product-led growth targeting quality professionals in manufacturing and regulated industries. No funding rounds, partnerships, M&A, or named enterprise customer logos are disclosed. The leadership team shown is a single named executive (President Paul Keller), consistent with the small 11–50 employee footprint.
