Investment portfolio

  • Beldex

    Led · Equity · Aug 2026

    Beldex is a Layer 1 blockchain built around mandatory privacy features such as stealth addresses and RingCT (Ring Confidential Transactions) to hide recipient addresses and transaction amounts. It offers a suite of decentralized private applications, including BChat for messaging and BelNet for browsing. The network transitioned to a Proof-of-Stake architecture secured by 10,000 BDX masternodes, which the project cites as enabling scalability and PoS-based passive income. Beldex plans to add EVM compatibility in 2027 to allow Ethereum developers to build privacy-preserving smart contracts and dApps on its chain. The recent $25M investment led by DWF Labs is earmarked to enhance its privacy technology. The project acknowledges regulatory scrutiny faced by privacy-focused networks and is building decentralized infrastructure to mitigate centralized listing risks.

  • Perceptron

    Participated · Equity · Jul 2026

    Perceptron operates a decentralised AI data mesh that aggregates global data collection into a contributor network for sourcing and verifying datasets. The platform is live and reports more than 807,000 nodes onboarded, with over 300,000 daily active users and earlier stages reaching more than 200,000 users across Telegram and Discord. Contributors retain ownership of their data and earnings and can monetise or withdraw them without intermediaries. Perceptron is launching a data-questing platform to enable AI companies to commission high-value datasets directly from the community, shortening sourcing timelines. The company aims to expand contributor tooling and rewards infrastructure and scale the network toward a long-term target of 5 million nodes. It recently raised $6.5 million in a strategic round to support these product launches and scaling efforts.

  • Veera

    Participated · Seed · Jan 2026

    Veera launched in January 2025 with the goal of becoming an easy on-ramp to crypto and the broader decentralized web. The product fuses a fast, privacy-centric mobile browser (complete with ad and tracker blocking) with a built-in, self-custody wallet that lets users hold assets, sign into dApps, and transact without switching apps. Beyond basic browsing and wallet functions, Veera is building toward an “on-chain neobank” model where users can earn, invest, borrow, and eventually spend—all within a single application. Engagement mechanics such as points, rewards, a curated dApp store, and in-app games aim to boost retention and simplify discovery for new crypto users. The company reports more than 2 million downloads since launch, signaling rapid early traction. Veera has now secured $10 million in pre-seed and seed funding to accelerate product development, expand its financial services, and support the wait-listed Veera Card that will let customers spend on-chain assets globally. The fresh capital provides runway for continued growth of its mobile-first platform and expansion of its unified crypto financial hub.
