Grant LaFontaine

Co-Founder and Chief Executive Officer Whatnot

Last Reviewed: September 19, 2026

Executive Summary

Grant LaFontaine co-founded Whatnot with Logan Head in 2019 and has run it as chief executive since. The company began as a marketplace for Funko Pop collectibles and became the largest livestream shopping platform in the United States — sellers running live video auctions in trading cards, sneakers, comics, coins and fashion, with buyers watching and bidding in real time. It is a format that had already taken hold in China and that US platforms had repeatedly failed to make work; Whatnot’s answer was to start inside a collector community that was already used to transacting this way, and then widen. By 2025 sellers moved more than $8 billion of goods through it, and in August 2026 a $545 million Series G valued the company at $20 billion.

Career Highlights

• Co-founded Whatnot in 2019 with Logan Head and has led it as chief executive ever since; the company went through Y Combinator’s Winter 2020 batch.
• Built the largest livestream shopping platform in the United States, which the company says holds roughly 60% of a live commerce market worth more than $22 billion.
• Whatnot surpassed $8 billion in livestream sales in 2025, up from about $3 billion the previous year, and said in August 2026 it had already passed that figure again.
• Closed a $545 million Series G in August 2026 at a $20 billion valuation, led by ICONIQ, Lightspeed and Avra — nearly double the $11.5 billion valuation set by the October 2025 Series F.
• Has raised approximately $1.5 billion for the company since 2019, across rounds led by DST Global, CapitalG and others.
• Previously worked in product development at Google and at Facebook.

Professional Journey

Before founding Whatnot, LaFontaine spent what the Los Angeles Business Journal describes as a long career in product development at Google and at Facebook. No title or date attaches to either role in any source consulted, so nothing more specific is claimed here; what it establishes is that he came out of large-platform product work rather than out of retail or collectibles.

He founded Whatnot in 2019 with Logan Head, and the company entered Y Combinator’s Winter 2020 batch. The starting point was narrow on purpose: a marketplace for Funko Pop figurines, a category with an engaged community, real authentication problems and buyers who already understood the idea of paying a premium for scarcity. In 2020 the company began hosting live shows in which sellers promoted products and answered questions from potential buyers in real time. That format, rather than the original listings marketplace, became the business.

Growth followed the format. Sellers moved roughly $3 billion of goods through live sales in 2024, mainly in trading cards and sports cards. In 2025 that passed $8 billion, a figure Whatnot publishes itself, alongside more than 560,000 hours of live shows hosted per week and an average of 98 minutes a day spent in the app — closer to social media engagement than to e-commerce, which is the point of the product.

The capital markets moved with it. A $265 million Series E in January 2025 valued the company at close to $5 billion; a $225 million Series F led by DST Global and CapitalG in October 2025 valued it at $11.5 billion; and on 7 August 2026 a $545 million Series G led by ICONIQ, Lightspeed and Avra valued it at $20 billion, roughly double the figure from ten months earlier. Total capital raised stands at around $1.5 billion.

LaFontaine framed the Series G around the supply side rather than the audience: “This investment allows us to build better tools, bring AI to more parts of the selling experience, help sellers reach more buyers, expand into new markets, and continue building the world’s biggest and most trusted marketplace.” That is consistent with how Whatnot describes its own mission — enabling anyone to turn a passion into a business — and with a company whose growth depends on sellers who can hold an audience for hours at a time.

The competitive position is not uncontested. eBay, Fanatics and TikTok Shop Live are all pushing into live commerce, and Whatnot’s claim to roughly 60% of the US market is the company’s own. Whatnot now employs around 800 people across hubs in Los Angeles, New York, Phoenix, San Francisco and Seattle in the United States, and Berlin, Dublin, Krakow and London in Europe.

Education

No education record could be established. Whatnot publishes no biography of its founders — the company has no About, press or leadership page — and none of the dated press consulted states where he studied.
