Management Consulting

From industry and market research, to opportunity spotting and strategy development, to operations and marketing plans, to execution and management, our team of professional consultants has over 350 years of combined experience to assist your business.

Black Swan Consulting

A Black Swan is an unexpected event that has wide ranging unpredictable consequences on many industries, and is often the cause of major volatility, such as the COVID-19 Pandemic. We can help your business increase resilience, improve adaptability, and minimize risk.

Education Technology

We invest in, and consult for Ed-tech companies across Canada. Our team has more than 100 years of combined experience in higher education. Whether you are in the seed stage, pre-revenue stage, or seeking additional funding to scale, we can help.

Investment Support

With our 300+ years of combined experience, we created an analysis tool to better determine which businesses are ideal for investment, which need more work, and which are likely to require a pivot. Let us help your company improve their position, and find funding!

Our Mission

To add meaningful value to our clients, improve their position, and give them a competitive advantage using valid, robust, and timely strategies.

A few things we’re great at

Opportunity Spotting

Do you have a Clear Understanding of the Opportunities in your industry and markets?

Business Planning

Do you have a Marketing Plan, Operations Plan and Financial Plan that are based on SMART goals?

Strategy Development

Have you developed a Value Proposition that is sound, cogent, and unbiased? Have you Validated your value proposition?

Value Creation

Maximizing Value is why you hire great managers. Creating Value is what entrepreneurs and consultants are brought onboard to do. Create new value, and gain a competitive advantage.

Executive Coaching

Are you a Subject Matter Expert in you industry? Are you aware of the trends and factors affecting change in your industry and market?


We use the most robust diagnostics and planning tools including the business planning methodology to determine what is taking place, what needs changing, and how to make it happen.

The Secret to Success

Slow careful planning, followed by rapid execution:

We specialize in Black Swan Consulting, Management Consulting, Entrepreneurship & E-Commerce Solutions. We bring a research-driven and entrepreneurial approach to problem solving and value creation. We help you stay on top of industry and market changes, make more informed decisions, and take the initiative to create real meaningful value.

Education Technology:

We are looking for education technology companies that want to grow. Our combined experience in higher education and consulting gives us the knowledge and network to help education technology companies better reach their goals, create value, and scale. We consult for, invest in, and run education technology companies ourselves, as the education industry is very near and dear to our hearts!

The CMC Difference

You will have access to several Certified Management Consultants (CMC). CMCs are the highest echelon of consultants worldwide, have the highest degree of professional ethics, and can work in over 40 countries without a Visa.

We bring the experience and expertise of consultants with graduate and doctoral degrees.

Value Proposition & Validation

Have you developed a Value Proposition that is sound, cogent, and unbiased? Have you Validated your value proposition?

Validation is as important as value proposition development. Like the laser-disc, something can be of high value, but not be valued highly.

Not Planning is Planning to Fail

Most new businesses fail within the first few years. A proper business plan is designed to minimize risk, maximize value, and foster innovation, giving your business a long-term competitive advantage.
