About

Built from experience, then structured.

Sigma comes from Erick Bouwer’s own personal and entrepreneurial life: the power of writing goals down, a simple daily success journal and years of leadership practice, books, tools and studies, brought into one practice.

Sigma works from the inside out: body, mind and soul.

Sigma is the companion that helps you work out what to focus on, why, when and how, and then follow through.

Why it exists

Most of it already exists. It just never worked together.

Journals, planners, training plans, nutrition plans, assessments, reviews: they exist, scattered and unaligned. Sigma brings them into one designed practice, so health and personal development move together.

I made mistakes so you don’t have to.
