Company News
VeryAI has raised $10 million in a seed funding round led by Polychain Capital, with participation from Berggruen Institute and Anagram.
VeryAI has raised $10 million in seed funding led by Polychain Capital, with participation from Berggruen Institute and Anagram, to build a Proof of Reality platform for the internet. The company's first product is a hardware-free palm scan identity verification system designed to combat AI-generated identities and media. Unlike facial recognition, palm patterns are rarely publicly shared and harder to replicate artificially. The platform converts palm scans into irreversible feature representations rather than storing raw biometric data. VeryAI is also developing deepfake detection systems to analyse whether digital content has been artificially generated or manipulated. The funding will support team expansion and product development as platforms increasingly struggle to verify real users and authentic content amidst rising bot activity and AI-generated fraud.
Polychain Capital has raised approximately $200 million in the first close of its fourth fund, with a total target of around $400 million, according to a person familiar with the matter. The raise signals continued investor interest in crypto despite the recent downturn in venture funding. Founded in 2016 by Olaf Carlson-Wee, Coinbase's first employee, Polychain has previously raised three funds with $2.6 billion in assets under management. The firm has led investments in companies including Uniswap and Yellow Card. The fundraising coincided with staff changes, as three research team members were let go whilst another was added. General partner Niraj Pant also departed. The firm is shifting focus towards Ethereum-based projects, particularly layer-2 networks and re-staking protocols, following successful deployment of its third fund.
Holaplex has raised $20 million in a Series A round led by Polychain Capital and Jump Crypto to expand its open-source NFT infrastructure on Solana. The company's codebase has been forked by dozens of teams and powered over $200 million in trading volume. The platform enables creators to launch custom NFT marketplaces without platform fees or permissions, offering decentralised control and community governance. Holaplex plans to use the funding to develop smart-contract royalties, token-gated experiences and integrated USDC checkout. The company is partnering with wallet providers, cross-chain bridges and analytics platforms, targeting 100,000 new artists and developers over the next 12 months. The round signals growing investor interest in permissionless NFT infrastructure.
Aria, a blockchain-based platform for tokenising intellectual property, has raised $15 million through seed and strategic funding rounds at a $50 million equity valuation. Polychain Capital and Neoclassic Capital co-led the seed round, with participation from Story Protocol Foundation and other investors. The company's first token, APL, launched in February and is backed by partial rights to royalties from songs performed by artists including Justin Bieber, BTS and Miley Cyrus. Aria is prioritising ecosystem growth over immediate monetisation, waiving origination fees in early launches to demonstrate its model. The platform aims to democratise access to music royalties, which have historically been restricted to institutional investors. The asset tokenisation sector is projected to reach $2.08 trillion by 2025.
