What The Lean Six Sigma Company does
The Lean Six Sigma Company is a privately held training and consulting organization headquartered in Rotterdam, the Netherlands, with a US regional office in Minneapolis, Minnesota. Founded in 2002 by Mischa van Aalten, the firm delivers Lean Six Sigma certification programs ranging from introductory White and Yellow Belt through Green Belt, Black Belt, and Master Black Belt, alongside Lean Practitioner and Lean Leader tracks. Service delivery is built around the Total Improvement Framework (TIF), the Continuous Improvement Driven Organization (CIDO) Model, and integration with established change management methodologies (ADKAR, Kotter's 8-Step), giving clients a structured DMAIC-based approach to process improvement, waste reduction, and quality control.
The company operates through a network of locally-staffed Managing Partners and country-specific websites covering more than 40 markets across Europe, North America, South America, Africa, the Middle East, and Asia. Revenue is generated primarily through professional services: open-enrollment and customized in-company training programs, enterprise deployment engagements, project coaching, and an organizational licensing program that allows clients to deliver Lean Six Sigma training internally. Named customers include Coca-Cola, Adidas, Heineken, Jaguar, Carrefour, AstraZeneca, United Nations, Gulfstream, and DS Smith, with cumulative scale claims of 50,000+ professionals trained and 4,000+ organizations transformed.
The business model is sales-led and direct-to-consumer hybrid: enterprise deployments are sold through local Managing Partners and bespoke project engagements, while individual certification is available via self-service enrollment on country-specific domains. Strategic partnerships with Rotterdam School of Management (Erasmus University) and the Baldrige Alliance provide academic and standards-based differentiation. Pricing is quote-based and not publicly disclosed, consistent with a project-driven professional services model.

The Lean Six Sigma Company competitors and assessment
Company assessmentDirect peers
- Six Sigma Global Institute (SSGI): SSGI provides accredited Lean Six Sigma certification programs (White through Master Black Belt) for individuals and corporations. It mirrors TLSSC's certification ladder and serves as a direct competitor for open-enrollment and corporate training deals.
- Simplilearn: Simplilearn offers Six Sigma Green Belt and Black Belt certification courses online and bootcamp-style, directly competing with TLSSC's individual certification track. It targets similar professionals seeking Lean Six Sigma credentials and stacks it with broader project management/PMP offerings.
- Aveta Business Institute: Aveta provides online Six Sigma and Lean Six Sigma certification programs (Green Belt, Black Belt, Master Black Belt) targeting working professionals. It competes head-on with TLSSC's open-enrollment certification offering at similar price points.
- MoreSteam: MoreSteam is an online Lean Six Sigma training provider with its own eLearning platform (EngineRoom) used by corporations globally. It overlaps with TLSSC on both individual certification and enterprise deployment training, often integrating statistics/data analysis tooling.
- GoLeanSixSigma.com: GoLeanSixSigma offers self-paced and instructor-led Lean Six Sigma training and certification, with a strong content library led by experts from the Lean Six Sigma community. It directly overlaps with TLSSC's certification business, particularly in North America.
Emerging players
- PMP/Coursera Six Sigma Programs (University of Illinois / Coursera): Coursera hosts accredited university Six Sigma specializations that compete with TLSSC's individual certification stream at lower price points. They represent the edtech-led shift toward self-paced, low-cost alternatives to instructor-led training.
- Wilson Perumal & Company: Wilson Perumal is a specialized operations excellence consulting firm that often engages on Lean Six Sigma deployments and operational transformations. It is a smaller, more boutique competitor to TLSSC's enterprise deployment services, often on complex manufacturing and supply chain projects.
Broad incumbents
- IASSC (International Association for Six Sigma Certification): IASSC is a globally recognized certification body for Lean Six Sigma. While not a training company per se, its accredited partner ecosystem directly competes with TLSSC's certification offerings and shapes industry credentialing standards.
- American Society for Quality (ASQ): ASQ is the largest U.S. quality professional association, offering recognized Lean Six Sigma certifications and training. It is a broader incumbent in the quality/operational excellence space and a key alternative credentialing body to TLSSC's programs.
- Accenture Operations & Management Consulting: Accenture runs large operational excellence and process improvement engagements that include Lean Six Sigma deployments.
