A bespoke approach to investment management

Our Mission

The Rosseau Group is a privately held investment-management firm based in Ontario. It was founded in 2013 to hold the founders’ growing asset management business, formerly operating as part of The Condo Store Inc. Long-time partners John Mehlenbacher and Simon S. Mass joined forces with Wall Street veteran Scott Moffat to create a firm designed to invest private funds in long-term, value-oriented projects.


As The Rosseau Group, we invest proprietary and 3rd-party capital in private market projects in 2 main categories: real estate and operating companies.

While each category contains a wide range of investment opportunities, we focus on residential and mixed-use development in our real-estate division, and on growth-capital opportunities in which we can secure a control position in our operating division.


We provide a bespoke approach to investment management, tailoring each fund to our investors’ needs.  Balancing returns with the risk of capital impairment, we harness our industry relationships to uncover private projects and provide diversified portfolios for our investors.

Secure, lucrative & transparent investments

It is our mission to provide investors with a secure, lucrative, transparent option amid a world of opportunities. We value the trust our investors place in us; it is our goal to earn that trust every day.

Our Wisdom

Our partners have experience in operations, real-estate brokerage, development, asset management, and investment banking. Our combined experience in multinational corporate entities and entrepreneurial ventures provides us with multiple perspectives from which to analyze investments.


Our entrepreneurial spirit opens the door to creative projects overlooked by more rigid firms. Our institutional approach ensures that all investments exhibit appropriate risk-return ratios.

Decades of local sales experience have provided us with a key competitive advantage: our projects are vertically integrated. In our real-estate division, our projects are supported by our affiliated companies: The Condo Store Group of Companies and Insider Condo Club. Our affiliates vet every project independently, providing their sales and marketing expertise from the outset. Our extended marketing engine shows investors that the most efficient sales force in the industry is not only ready to sell the project, but has also helped design the project for maximum profitability.

We safeguard our investments by selecting projects in which we have specific expertise and the ability to add the most value. We focus on Southern Ontario, where decades of experience in various aspects of the industry and the support of our affiliates are maximized.


We also venture into other progressive and influential markets, such as Miami and NYC, where our development partners have expanded their operations, and we have history of successful proprietary investment.

Investment Strategy

At The Rosseau Group, we leave high-risk opportunities for others. We seek lucrative opportunities with an appropriate margin of safety. Our investments provide investors with secure, predictable returns that are less volatile than the alternatives. The illiquid nature of our investments is balanced by superior returns and favourable tax treatment. We target overlooked projects outside the GTA, where fewer investors and developers compete.


We emphasize projects for which our greater group of companies can manage the most important aspects. Our careful due-diligence process – performed by all interested parties – is reflected in the accurate financial projections we create.

Most importantly, we stand by our investments, co-investing in every fund or project. If a project is unworthy of our capital, it is unworthy of our investors’.


In the real-estate and broader investment management industry, it’s common for managers of various types to have incentives that conflict with those of investors. At The Rosseau Group, we proudly take the concept of aligned incentives to the extreme.


In most projects, we involve carefully selected service providers. Some are relatively minor; some are an integral part of the project’s foundation. We convert the most important service providers into partners.

In all of our projects, material service providers – sales managers, builders, and often others – are required to invest alongside us. We believe that profit participation should always outweigh management fees. We align incentives in every way possible.


Finally, at the end of the project, we – the partners of The Rosseau Group – defer our compensation until all investors have received an agreed-upon base return. We require ourselves to exceed the returns available to you elsewhere in order to deserve any reward for our efforts. From beginning to end, aligned incentives ensure that we are never merely advisors; we are your partners.

Our Founders

Our story began with a simple objective: the acquisition of pre-construction condominiums…

in bulk.


As is the case with many successful business ventures, our success stemmed from foresight, passion, vision, and impeccable timing. With one meeting of the minds between serial entrepreneur Simon S. Mass and a newly appointed executive at Concord CityPlace, John Mehlenbacher, the foundation was established – The Condo Store Group of Companies was born.

First came The Condo Store, then TCS Marketing Systems, and in late 2014 the disruption that revolutionized pre-construction condo sales and marketing: Insider Condo Club.


Our independent, but highly synergized companies work fluidly together for investors, property owners, landlords, financial institutions, developers, and, ultimately, for great cities across North America. It’s a true Canadian success story. Stellar performance records and record-breaking ROIs have created loyal clients who continue to re-invest and refer.

A Canadian Success Story

With a combined industry experience of over 40 years and a partnership that has had its hands in over $23 billion in development projects and sales, the legacy continues. Our synergized group of companies established over the last 12 years continues to grow, providing The Rosseau Group with a unique competitive advantage.

John is a Toronto native with over sixteen years of real estate experience and ten years of asset management experience. He began his career by learning the condo development industry from the ground up and working for the industry leaders. He started with the successful launch of 500 and 550 Queen’s Quay on Toronto’s waterfront. Over the next decade, he spearheaded sales for Canada’s leading community developer, Concord Adex, a firm in the forefront of re-facing the Toronto and Vancouver skylines with the largest master planned communities in North America.


In 2004, he and Simon S. Mass founded a ten person boutique firm that evolved into The Condo Store; a firm designed to link their clients and investors to major international developers from all over the globe, including the Far East, Dubai, and the United Kingdom. John’s efforts in both garnering and managing the sale of over $5 Billion / 10,000+ individual condo units have been regularly recognized through coveted industry awards.


Today, The Condo Store is a 90+ person firm operating in three independent segments: In-House Sales and Marketing, Full Service Real Estate Brokerage, and the Bulk Investment Group – the division that has become a leading force in Canada’s pre-construction industry.




Originally from the United Kingdom, Simon is a Torontonian with over seventeen years of real estate investment experience and ten years of asset management experience. Simon holds an Industrial Engineering Degree as well as an MBA specializing in International Marketing. With a development and landlord foundation dating back two generations, Simon has been a lead player in the high volume pre-construction industry in Canada and internationally and has amassed over $5 billion in transactions to date.


In the 1990s, Simon established Toronto’s wholesale/bulk market segment by connecting a global network of investors to Southern Ontario’s booming condominium market. This approach has allowed investors to reap the rewards of ROI’s that have ranged from 30% to 100% per annum on their initial investments into the pre-construction market in what is regarded as the largest condominium market in the world.


In 2004, he and John Mehlenbacher founded a ten person boutique firm that evolved into The Condo Store with over 300 sophisticated high net worth clients from around the globe. Over the years, their investments have spread from pre-construction condominiums to a wide range of investments in the real estate industry under the watchful eye of The Condo Store team.

Our affiliated companies provide us with a unique competitive advantage. Our integrated group of real-estate companies constantly share information and serve each other for mutual benefit. When The Rosseau Group vets a new opportunity, we incorporate our affiliates in the diligence process. The experts at The Condo Store, Marketing Systems, and Insider Condo Club are given the opportunity to vet the project, providing candid feedback in an open process.

After each company performs its diligence, the sales teams provide detailed input into not only a potential sales program, but also the design of the residential structure. Our affiliates help us determine the most profitable use for the property. In the end, once we have chosen to invest in a project, our affiliated partners stand by our shared decision. They not only sell the units, but also invest as part of our overall partnership, further aligning incentives for all parties.

Our elite sales teams ensure that our projects are designed for success from the very beginning. By controlling the process from start to finish, we provide cogent development plans, offer unparalleled transparency, and provide the comfort our investors deserve.
