- World Network
Participated · Initial Coin Offering · Jul 2026
World, operated by Tools for Humanity and co-founded by Alex Blania and Sam Altman, offers an online verification system centered on its World ID "proof of human" credential. To obtain a verified World ID, users undergo an iris scan via a physical Orb that converts the iris into a cryptographic identifier; Orbs are deployed at the company’s offices and partner locations. The project includes a mobile app that serves as a custodial wallet where users can hold or trade the WLD token. The effort began as Worldcoin and later rebranded to World amid industry backlash; the company has announced partnerships with firms such as Tinder, Zoom and Docusign. Despite those moves and a new app release, the company has struggled to scale consumer adoption and conducted layoffs in June.
- Variational
Participated · Series A · May 2026
Variational operates a zero-fee trading platform (Omni) that aggregates liquidity from both on-chain and traditional markets to offer perpetuals and generalized derivatives. The protocol entered invite-only private beta in January 2025 and has since processed over $200B in trading volume, served 50k+ accounts, amassed over $750M in open interest, and shared over $7M in rewards with traders. Its initial RWA rollout (Phase 1) includes gold, silver, copper and WTI crude to validate cross-margining and on-chain settlement using aggregated crypto-native liquidity. Phase 2 intends to route liquidity directly from TradFi sources and expand to 100+ new markets. Variational’s 2026 roadmap includes listing additional RWA markets, deepening liquidity via partnerships, and releasing a trading API. The team includes veterans from firms such as Google, Meta, Virtu, IMC, and Jane Street.
- Turnkey
Participated · Equity · May 2026
Turnkey builds programmable infrastructure that combines non-custodial embedded wallets with a verifiable cloud environment to enable automated on-chain transactions, gas sponsorship, and secure off-chain workload enforcement. The company powers major digital-asset platforms including Polymarket, Flutterwave, Anchorage Digital, and Tools for Humanity’s World App. Turnkey is led by CEO and co-founder Bryce Ferguson alongside co-founder Jack. It has raised over $65m in total funding to date and recently secured an additional $12.5m. The new capital is earmarked to accelerate the public launch of its Turnkey Verifiable Cloud, expand its engineering team, and grow operational infrastructure across crypto, fintech, and AI. The company is headquartered in New York City.
- Bluesky
Led · Series B · Mar 2026
Bluesky operates a social network and an open social ecosystem built on the AT Protocol (ATProto) that enables interoperable apps. Since its Series A, the platform has grown from 13 million to over 43 million global users and its Atmosphere network contains around 20 billion public records. The developer ecosystem is expanding, with over 400,000 monthly downloads of developer tools (SDK) and more than a thousand apps on ATProto used weekly. Bluesky has not integrated cryptocurrencies and is not built on blockchain technology, though some crypto-oriented investors have backed the company. Leadership changed when CEO Jay Graber transitioned to chief innovation officer, and the company says it is hiring a new CEO to drive commercial growth. The company is using recent funding to scale its team and continue development of its app and underlying protocol.
- Tangled
Participated · Equity · Mar 2026
Tangled provides an open, extensible network where developers can self-host repositories on lightweight servers called “Knots” that seamlessly federate into the broader platform. Built on the AT Protocol, Tangled supports stacked pull requests and agent-driven workflows, aiming to serve indie developers, open-source communities, and the emerging era of AI coding agents. The community-first product already counts roughly 900 Discord members and 18,000 Bluesky followers who help shape feature development. While the service is currently free and unmonetised, the founders plan to follow a Tailscale-style model in which individual and open-source users remain free while businesses pay for advanced capabilities. Tangled’s emphasis on data sovereignty and European jurisdiction seeks to address concerns over Microsoft’s ownership of GitHub and its AI training practices. The company was founded by brothers Akshay and Anirudh Oppiliappan, who previously built large-scale distributed systems at Y Combinator startups, operating from London and Helsinki respectively. The recent capital raise positions Tangled to scale its infrastructure and broaden its community footprint.
