• MAT -0.38%

Shark Tank's Kevin O'Leary is known for making big deals, but one of the biggest of his career may have come with a much smaller personal payday than the headline number suggests. The deal illustrates why a company's sale price tells only part of the story for its founders and investors.

In 1999, Mattel acquired The Learning Company (TLC), the software company O'Leary helped build from the original SoftKey, in a stock deal valued at as much as $4.2 billion. Yet, a 2017 report by The Globe and Mail found O'Leary ultimately walked away with about $11.2 million. Still a fortune, but a fraction of the multibillion-dollar price tag.

The biggest reason comes down to ownership. O'Leary held only a relatively small stake in TLC when Mattel came calling. TLC was a publicly traded company, so the multibillion-dollar price tag applied to the company as a whole, with shareholders receiving Mattel stock based on how much TLC stock they owned. O'Leary was one of those shareholders, not the sole owner.

An earlier Globe and Mail report suggested his $11.2 million take may have included nearly $6 million from selling most of the Mattel shares he received in the deal, along with up to $5.25 million in severance when he later left Mattel.

According to the Globe and Mail, the acquisition itself quickly went sour. Within months, TLC was losing money, contributing to a sharp drop in Mattel's shares, and O'Leary left about six months after the deal closed. Mattel CEO Jill Barad followed a few months later, and the toy company eventually unloaded TLC after the software division kept racking up losses.

Importantly, $11.2 million wasn't necessarily all O'Leary earned from TLC. The figure covers the Mattel deal and his departure from the company, not any salary, earlier stock sales, or other compensation he may have earned during his years at SoftKey and TLC.

The sale price isn't the payday

O'Leary's experience with TLC isn't unique. Entrepreneurs often give up pieces of their companies as they raise money and bring on investors, meaning a big acquisition price doesn't necessarily translate into a dollar-for-dollar payday for the founder.

The terms of the sale can widen that gap. A cash acquisition can produce an immediate payout, while an all-stock deal leaves shareholders holding stock that can rise or fall in value before they sell it. Debt, taxes, transaction costs, and other obligations can eat into what's left.

TLC offers an extreme example. Mattel may have valued the entire company at as much as $4.2 billion, but O'Leary's share of the acquisition depended on how much of the company he actually owned. The billions belonged to the deal; they were never his alone.

It's also not unusual for founders to own much less of their companies by the time a sale comes around. According to Carta's 2026 Founder Ownership Report, the median founding team owns about 56% after a seed round, typically the first major round of outside funding. By Series A, when companies often raise more money, that falls to 36%, and by Series C, founders collectively own just around 16.1% of the firm. So even when a company sells for a fortune, the founders may walk away with only a fraction of the headline price.

A caveat on being "stinking rich"

Whatever O'Leary ultimately pocketed from the Mattel deal, he has described the 1999 sale as the moment he became a millionaire. In a 2025 LinkedIn post, he recalled waking up after the deal and thinking, "I'm stinking rich."

O'Leary has done pretty well since then. His net worth is now estimated at $400 million, built through his various businesses and investments.

But O'Leary says getting rich was an outcome of entrepreneurship, not the reason he became an entrepreneur in the first place.

"[I]t never was for the money and what I've learned is if that's all you are trying to do as an entrepreneur, you will fail," O'Leary wrote in the post. "If it's just the greed of money, you will fail. You have to have a passion for what you're doing beyond financial rewards."
