Mark Rivkin Net Worth: Estimate, Sources, and Methodology

The Mark Rivkin most people are searching for is a Canadian entrepreneur and investor based in Toronto, best known as co-founder of CryptoLogic (the pioneering internet gambling software company he launched with his brother Andrew in 1995) and later as co-founder of QT Inc. and founder of Helix Healthcare Group. Based on publicly available information about his business history, equity positions, and industry context, a reasonable estimated net worth range for Mark Rivkin as of May 2026 is $3 million to $10 million CAD, with the most defensible midpoint sitting around $5 million to $6 million CAD. That range carries significant uncertainty because most of his current assets are tied up in private companies with no public filings.

Which Mark Rivkin are we talking about?

There are at least a few people named Mark Rivkin in public records. One appears in a UK Ofcom telecommunications consultation response, clearly unrelated to the Canadian entrepreneur. For anyone arriving here via a search tied to business, cryptocurrency history, healthcare, or Canadian finance, the relevant person is the Toronto-based Mark Rivkin who attended the University of Western Ontario (graduating in 1993), founded a student note-taking business called Campus Notes while still in school, then co-founded CryptoLogic with his brother Andrew Rivkin in February 1995. That founding story is cross-confirmed by Wikipedia entries for both Mark and Andrew Rivkin, as well as CryptoLogic's own entry and Ontario Securities Commission (OSC) regulatory documents that reference both brothers by name.

After stepping down as CryptoLogic's CEO in January 2001 (while remaining on the board), Mark went on to co-found QT Inc. in 2004 alongside Harvey Solursh. QT Inc. is a Toronto-based private investment company focused on real estate (both commercial and residential), mortgages, and financing. In 2014 he founded Helix Healthcare Group, a mental health and addiction services organization, with Solursh also listed as a business partner. Helix expanded to a second location in mid-2014, and the organization continues to operate under the Helix Health Group branding as of this writing. These three ventures, CryptoLogic, QT Inc., and Helix Healthcare Group, are the core biographical anchors that distinguish him from other Mark Rivkins in public records.

What "net worth" actually means here

Net worth is total assets minus total liabilities. For a private individual like Mark Rivkin, that means adding up the estimated value of his equity stakes in private businesses, any real estate he holds, investment portfolios, cash, and other assets, then subtracting mortgages, business debts, and any other known liabilities. Because he does not run a publicly traded company today and has not filed personal financial disclosures with any regulator, there is no single authoritative number. You can also review other context around dan riskin net worth to compare how these wealth estimates are typically built. Everything here is an estimate built from public signals: corporate history, industry benchmarks, known business activities, and secondary sources like Crunchbase and press releases. One online estimation tool pegged "Mark Rivkin net worth" at approximately $2. If you are specifically looking for Rene Rivkin net worth figures, the most reliable approach is to compare public market activity and any disclosed holdings Mark Rivkin net worth. 45 million USD, but that figure is generated algorithmically from social and web signals rather than from financial filings, so treat it as a rough floor rather than a definitive answer.

Where the money likely comes from

The CryptoLogic windfall

CryptoLogic is the biggest single wealth event in Rivkin's history. Founded in a basement in 1995, the company listed on the Toronto Stock Exchange in September 1998 and on NASDAQ in March 2000, right at the peak of the dot-com boom. As co-founder, Mark held a meaningful equity stake at the time of those listings. The NASDAQ listing in particular would have created substantial paper wealth, and depending on when or whether he sold shares, real cash. The OSC records confirm that as of at least one significant corporate event, both Andrew and Mark Rivkin held shares and were being formally advised on tender decisions, which means the stake was material enough to require regulatory disclosure. Precise share counts and sale prices are not in the public record, but tech founders who took a company to NASDAQ in 2000 and retained even a fraction of their equity through the listing typically realized millions. This is the most plausible source of his foundational wealth.

QT Inc. and real estate exposure

QT Inc., co-founded in 2004, operates in commercial and residential real estate, mortgages, and financing in the Toronto market. Toronto real estate appreciated dramatically between 2004 and the early 2020s, and a private investment firm with equity exposure to that market over two decades would have generated substantial returns. The exact deal flow and Mark's ownership percentage in QT are not public, but as a co-founder of a private investment company, his stake in QT's accumulated real estate and mortgage assets is a significant component of any net worth estimate. This is speculative by necessity, but it is a grounded speculation.

Helix Healthcare Group

Helix Healthcare Group, launched in 2014, operates in the private mental health and addiction treatment space. Private healthcare clinics in Canada can be profitable businesses, but they are also operationally intensive and heavily dependent on staffing costs and patient volume. Helix expanded to a second location in 2014, suggesting early growth momentum. The organization continues to operate as of May 2026. As CEO and co-founder, Mark likely holds a meaningful equity stake in Helix, though the valuation of a private healthcare services company is harder to estimate without revenue figures. This is a contributing asset but probably not the largest one.

The estimated net worth range, with the math shown

The wide range reflects genuine uncertainty. The CryptoLogic contribution is the hardest to pin down because it depends entirely on when and how much equity he sold, and those transactions were never disclosed publicly at the individual level. If he held shares through the dot-com crash in 2000-2001 and sold late, the proceeds would be much lower than if he took money off the table at or near the NASDAQ listing. The $5 million to $6 million midpoint assumes he captured a moderate portion of the CryptoLogic upside, maintained a modestly profitable stake in QT over two decades of Toronto real estate appreciation, and built a small but real equity position in Helix. If you are specifically looking for a bottom-line figure, the net worth estimate discussed above is the closest practical way to interpret Ron Rivlin Net Worth in this context. For context, the algorithm-based estimate of roughly $2.45 million USD (approximately $3.3 million CAD) falls within the lower bound of this range, which is consistent.

What can move this number up or down

Net worth for someone in Rivkin's position is not static. Several factors could shift the number materially in either direction over time.

• Toronto real estate market cycles: QT Inc.'s portfolio value is directly tied to Canadian commercial and residential property markets. A sustained correction (as seen in parts of the 2022-2024 period) would reduce the value of any holdings not yet liquidated.
• Healthcare sector performance: If Helix Healthcare Group expands significantly or is acquired by a larger healthcare operator, the equity value increases. If the business contracts or closes locations, it decreases.
• New venture launches: Rivkin has a track record of founding new companies roughly every decade. Any new venture could add or subtract from net worth depending on outcome.
• Litigation or regulatory exposure: As a securities-registered individual (via the OSC record), any regulatory action or civil litigation involving his businesses would affect both assets and liabilities.
• Macro interest rate environment: As an operator in mortgages and financing through QT Inc., higher interest rates over the 2022-2024 period may have compressed deal margins or increased borrowing costs on held properties.
• Private company exits: If QT Inc. or Helix Healthcare Group is sold or recapitalized, the liquidity event would dramatically clarify the actual net worth figure.

How to verify or update this estimate yourself

Because Rivkin's wealth is almost entirely in private vehicles, there is no single database that will give you a confirmed number. But you can meaningfully narrow the uncertainty with a few targeted searches. If you are comparing entrepreneur wealth patterns, you can also review stuart rabinowitz net worth as a related benchmark for how private-market results translate into public estimates.

1. Ontario Business Registry (Ontario.ca): Search for QT Inc. and Helix Healthcare Group to confirm current corporate status, registered directors, and any filed annual returns. This won't show financials but confirms whether the companies are active and who is formally listed.
2. SEDAR+ (sedarplus.ca): Search for CryptoLogic historical filings. Insider trading reports filed during Rivkin's time as an officer or director would show share transactions, including sale dates and prices. This is the best way to reconstruct what he actually made from the NASDAQ listing.
3. OSC Enforcement and Decisions database (osc.ca): The publicly available OSC decision documents already confirm his name in CryptoLogic matters. Searching his name here can surface any additional regulatory proceedings.
4. Crunchbase (crunchbase.com): The Mark Rivkin profile and Helix Healthcare Group profile provide secondary confirmation of his roles but should be cross-checked against official registry sources, not used as primary evidence.
5. Canada Revenue Agency / Strathmore: For Canadian executives, there is no public equivalent of the U.S. SEC Form 4 for private company ownership. Your best lever is the SEDAR+ insider filing history from the CryptoLogic years.
6. News database search (Google News, Canadian Newswire archives): Search "Mark Rivkin" plus "QT Inc.", "Helix Healthcare", or "CryptoLogic" to catch any press releases about funding rounds, acquisitions, expansions, or litigation that would affect valuation.

If you find a SEDAR+ insider report showing Rivkin sold a large block of CryptoLogic shares at or near the March 2000 NASDAQ peak, revise the top end of the estimate upward significantly. If the filings show he held through the crash and sold late, trim the CryptoLogic contribution toward the lower bound. That single data point would do more to improve the estimate than anything else currently available.

How this compares to others in his orbit

Mark Rivkin operates in a similar entrepreneurial lane to other figures researched on this site. His brother Andrew Rivkin shares the CryptoLogic founding story, so Andrew's wealth trajectory is the closest natural comparison point. Beyond the Rivkin family, individuals like Rene Rivkin (the Australian stockbroker and media personality, no known relation) represent a very different wealth profile built on public markets activity rather than tech entrepreneurship. The common thread in this category of public figure is that net worth is heavily event-driven, shaped by one or two major liquidity events rather than a steady salary accumulation.

This estimate was last reviewed and updated in May 2026. Because Rivkin's businesses are private, this figure will not update automatically. If you find new information through the verification steps above, particularly SEDAR+ insider filings or news of a business sale or funding event, the range should be revised accordingly.
