B-Stock
B-Stock turned retail's awkward back room - returns, trade-ins and excess goods - into a data-rich B2B market. Its real product is not the pallet. It is a faster, more legible second life for inventory.
Bob's Watches
Bob's Watches is the world's largest online marketplace dedicated to pre-owned Rolex and luxury watches. Founded in 1999 and reshaped by CEO Paul Altieri after 2010, the company pioneered the transparent 'Rolex Exchange' - publishing live buy and sell prices for every model, like a stock exchange for watches. Based in Newport Beach, California, it authenticates and holds its own inventory of certified used Rolex, Patek Philippe, Omega, Tudor, Cartier, Audemars Piguet and more, letting collectors and first-time buyers transact at fair market value.
Stake
Stake is a Dubai-based digital real estate investment platform that lets people buy fractions of income-generating property from as little as AED 500. Investors earn passive rental income and capital appreciation while Stake handles sourcing, acquisition, management and exit. Regulated by the DFSA in the UAE and the CMA in Saudi Arabia, the platform serves more than two million users across 181 countries and has expanded from Dubai into Saudi Arabia, Abu Dhabi and US industrial real estate.
Landa
Landa was a New York fintech that let anyone buy fractional shares of single-family rental homes for as little as $5 through a mobile app, collecting monthly dividends from rent and any appreciation. Founded in 2019 by Yishai Cohen and Amit Assaraf, it packaged each property into its own LLC, managed the homes with proprietary software, and ran a secondary marketplace for trading shares. After raising $33M in equity and roughly $62M in debt and surpassing 200,000 registered users, the platform went dark in 2025 amid lender lawsuits, missed dividends, and a court-ordered receivership over 119 properties.
Masterworks
Masterworks is a New York fintech that lets everyday investors buy fractional shares in multimillion-dollar blue-chip paintings by artists such as Basquiat, Picasso, Warhol and Banksy. Founded in 2017 by serial entrepreneur Scott Lynn, the company buys individual artworks, registers each as a public offering with the SEC, and sells shares for as little as $20, then holds the work for several years before selling it and distributing proceeds. It reached unicorn status in 2021 after a $110M Series A and has grown to more than one million members.
Equitybee
Equitybee is a financial technology marketplace that connects startup employees who can't afford to exercise their vested stock options with accredited investors willing to fund the exercise in exchange for a share of the future upside. Founded in 2017 by three childhood friends and headquartered in Palo Alto, the platform lets employees convert paper equity into real ownership - or cash - without waiting for an IPO, while giving investors a rare way to buy into pre-IPO companies they otherwise couldn't reach.
Spoiler Alert
Spoiler Alert is a Boston-based B2B software company that helps the world's largest consumer packaged goods makers sell off excess and short-dated inventory before it ends up in a landfill. Its platform digitizes the messy, manual liquidation process - automating listings, optimizing pricing and freight, and matching surplus product to a curated network of discount retailers and food banks. Founded by MIT Sloan classmates in 2015, the company works with brands like PepsiCo, Nestle, Kraft Heinz, Campbell's, and Danone, and says it has helped divert more than 200 million pounds of food from waste.
Nasdaq Private Market
Nasdaq Private Market (NPM) is an independent, New York-based financial technology and broker-dealer company that runs a marketplace for trading shares of private, pre-IPO companies. Through its SecondMarket platform, NPM helps startups, employees, shareholders, and institutional investors find liquidity before an exit - via tender offers, auctions, block trades, and custom company marketplaces - while bringing price discovery, data, and settlement infrastructure to a notoriously opaque corner of finance.
