- Anchor Watch
Led · Equity · Sep 2023
AnchorWatch develops Trident Vault, a protocol-native custody solution designed for commercial bitcoin holders and backed by regulated, high-quality insurance. Trident Vault integrates dispersed workflows for remote teams and introduces key holder seniority and time-locked spending conditions to enable on-chain compliance and governance. The product targets family trusts, funds and pensions, family and multifamily offices, bitcoin miners and mining pools, and advisors involved in estate and inheritance planning. AnchorWatch is led by cofounder and CEO Robert Hamilton. The company plans to use new funding to complete regulatory and capital requirements, deliver Trident Vault to customers, begin selling policies, and undergo security audits by credentialed firms. AnchorWatch intends these steps to further solidify Trident Vault as a custody solution for enterprise use.
- Primal
Led · Seed · Jul 2023
Primal develops a suite of social apps that combine a Twitter-like interface with the open-source Nostr protocol, emphasizing censorship resistance, account ownership, and decentralization. Its product includes instant "zap" functionality to send small amounts of bitcoin between users and posts. The company is expanding beyond its web app into mobile apps to increase user choice within the Nostr ecosystem. Primal positions itself as the first venture-backed startup focused solely on bitcoin-infused Nostr applications. The broader Nostr protocol already claims over 30 million users, which Primal expects to leverage as it grows. Financially, Primal recently closed external funding to support product expansion into mobile and continued development of zap features.

Strike says its payments are accessible to any consumer who can move money using the Lightning Network, including more than 70 million Cash App users. The company plans to release new product lines and API capabilities to enable large financial institutions and businesses to both receive and send payments using Strike's infrastructure.
