Grant LaFontaine and Logan Head were both collectors and entrepreneurs. LaFontaine had previously co-founded a startup, and Head had worked at GOAT (the sneaker marketplace). They shared a fascination with a peculiar phenomenon: Pokémon card sellers were going live on Instagram, holding up cards to the camera and taking bids in the comments.

The Instagram Live Hack

In 2019, the collectibles market was booming. Pokémon cards, sports cards, Funko Pops, and vintage toys were experiencing a renaissance driven by millennial nostalgia and pandemic-era hobby adoption. Sellers had discovered that livestream auctions generated excitement and higher prices than static listings.

• Track bids manually in rapidly scrolling comments
• Handle payments via DMs or external platforms
• Ship items without integrated logistics
• Build trust without buyer/seller ratings

LaFontaine and Head saw the opportunity: build a purpose-built platform for live commerce in collectibles.

Y Combinator and Early Traction

Whatnot went through Y Combinator's Winter 2020 batch. The initial launch focused on Funko Pop figures — a category the founders knew deeply. They personally recruited sellers from Instagram Live and Facebook groups, offering a seamless experience: built-in bidding, payment processing, and shipping labels.

The early seller onboarding was highly curated. Whatnot verified every seller's inventory and authenticated items to build trust. This curation strategy meant slower initial growth but much higher quality — a lesson from GOAT's playbook.

The Pandemic Accelerant

COVID-19 lockdowns in March 2020 were rocket fuel for Whatnot. People stuck at home were simultaneously: 1. Rediscovering childhood collections 2. Looking for entertainment (live auctions are genuinely fun to watch) 3. Seeking side income from selling collectibles

Whatnot's live format was perfectly positioned. A single livestream auction could generate thousands of dollars in sales in an hour. Top sellers were making six figures monthly.

Category Expansion

• 2020: Pokémon cards, sports cards
• 2021: Sneakers, vintage clothing, comic books
• 2022: Electronics, jewelry, coins
• 2023: Fashion, beauty, home goods

Each expansion followed the same playbook: identify a category with passionate collectors, recruit the top sellers from that community, and build category-specific features.

The fundraising was justified by extraordinary growth metrics. By 2022, Whatnot was processing hundreds of millions in GMV annually, with live auctions generating 10x the engagement of static listings.
