Highstock’s $30M Series A Puts Beauty Overstock on Whatnot and TikTok Live

Highstock is an AI-powered B2B marketplace that matches brands holding excess inventory with a vetted network of wholesale buyers. Founder Camille van Horne, previously a product lead at Instacart, built the matching, logistics, and compliance layer so brands can clear surplus product without the fire-sale optics of classic off-price and jobber channels.

The $30 million Series A is earmarked to widen the buyer network and extend the model from beauty, its current beachhead, into apparel. Van Horne told WWD that apparel overstock is roughly five times the size of the beauty liquidation market, which makes beauty a proving ground rather than the ceiling for Highstock’s model.

Beauty inventory carries expiration dates that apparel overstock does not. Retailers typically push back once remaining shelf life drops under about 18 months, which turns a demand-forecast miss into a fast-moving clock instead of a seasonal markdown decision.

Camille van Horne described the pressure to BeautyMatter on November 16, 2025: “In beauty, expiration dates make brands even more anxious as they approach the three-year mark.” The scale of the problem is concrete: Shopify data cited in that same BeautyMatter reporting found only about 50% of beauty products produced in a given year sell that year, with roughly 10% of unsold inventory incinerated, a loss BeautyMatter put at close to $50 billion annually.

Highstock supplies live-commerce sellers and international buyers directly, turning warehouse overstock into sellable lots for creator-run live rooms instead of routing it through classic liquidation. WWD named The Boyzzz, a Whatnot seller with nearly 170,000 followers and more than 145,000 sales, as one buyer on this supply path.

International buyers make up about 40% of Highstock’s business, a mix WWD reports includes live sellers and retailers outside the United States. For a beauty brand clearing short-dated stock, that gives overstock a second GMV path: product still looks like product on camera, which off-price bins and destruction bins do not offer.

A brand carrying short-dated or slow-moving beauty SKUs should treat a Highstock-class surplus marketplace as a live-commerce channel decision, not a finance write-off, and confirm three things before choosing destruction.

1. Can the lot move through vetted live sellers on Whatnot or TikTok Live without brand-damaging optics?
2. Is remaining shelf life still camera-safe, even if a retail partner will not take the SKU back?
3. Does the buyer network skew toward international live commerce, roughly 40% by Highstock’s own figures, in a way that matches where the brand will accept gray-market bleed?

Storika’s discovery layer covers more than 7 million creator profiles, including Whatnot and TikTok Live sellers with an established track record moving beauty and personal care product. A brand routing surplus inventory through a marketplace like Highstock still needs to vet which live sellers actually convert in its category, and Storika reconciles that seller’s performance across TikTok, Instagram, and Whatnot before a brand commits inventory to one live room.
