Six Sigma

What Six Sigma does

Six Sigma (legal entity: Global Six Sigma USA LP; dba 6sigma.us) is a privately held, Austin-Texas-based Lean Six Sigma training and certification company founded in 2004. It delivers a belt-based certification portfolio (White, Yellow, Green, Black, and Master Black Belt) plus adjacent curricula in Lean, Design for Six Sigma (DFSS), Root Cause Analysis (8D), Project Management (PM4PI), Systems Thinking, and Champion training, with instructors led by President and Master Black Belt Peter Peterka and a bench of 20+ MBB consultants with industry experience at firms such as 3M, GE, Motorola, HP, Dell, Intel, Xerox, and Seagate.

The product is delivered across five formats — live virtual instructor-led (Zoom), self-paced online (LockLizard-secured Learning Center), classroom training at 30+ North American cities, blended cohorts, and onsite corporate deployments — and is supported by a Spanish-language sub-brand (sixsigmaespanol.com) for Hispanic markets. The technology stack is largely third-party (Zoom, LockLizard, Minitab, PayPal) layered over proprietary curriculum and assessment content; no AI/ML components are disclosed. The company is PMI, IACET, ISSSP, SHRM, and BBB accredited and holds U.S. GSA Schedule Contract #GS-02F-114AA for federal sales.

The business model is predominantly transactional, pay-as-you-go course and certification fees, with pricing ranging from $99 (self-paced White Belt) to $4,975 (Master Black Belt) and classroom pricing typically 2x virtual. Revenue is diversified across individual self-serve e-commerce, mid-market open-enrollment classes, enterprise onsite training, and government sales. Over its lifetime the company has trained 25,000+ participants across 5,000+ organizations, but it has no disclosed external funding, no parent company, and a headcount of 11–50, implying a small, profitable services firm rather than a venture-backed growth company.
