4K is building the world's most incentive-aligned, peer-to-peer marketplace. Our mission is to empower humanity to transact with more trust, more transparency, more speed, and with a 95+% reduction in fees. Unlike incumbent marketplaces that win at the expense of their users, we win alongside our users. We've raised $3M from some of the world's top blockchain VCs (Electric Capital, Consensus Capital, Crosscut VC, and more) and angels.

For something to be a true industry disruptor, it can’t be just two or three times better than what already exists. It has to be at least 10, if not 100, times better. By using blockchain technology to leverage NFTs and our own native token, we are able to build the marketplace of the future.

Web1.0 = Ebay
Web2.0 = Curated Marketplaces
Web3.0 = 4K
