| Clearmatics | Founded in 2015, Clearmatics is a London-based blockchain company. We build member-owned and governed decentralised network platforms for the peer-to-peer exchange of tokenised value between network members. Our ethos and architecture is grounded in protocol, peer-to-peer architecture, removing friction and market inefficiencies, strong securityguarantees and interoperable exchange across platforms to build a peer-to-peer ecosystem for market infrastructure. Our focus is capital markets; we work with firms that have the ambition to reinvent the industry's business models.Our technology is p2p network platforms and protocol first - protocol suite, software that implements those protocols and provides client software and infrastructure for p2p networks. Its based on Ethereum and we call it Autonity - the protocol, the Geth-based client.We use our technology to build p2p networks and dFMI.P2p networks are private, member-owned and governed networks that enable peer-to-peer transfer of financial value and automation of contractual and fiduciary operations without reliance on trusted third-parties. Such decentralised networks can interact with one another, creating a wider ecosystem of value and leveraging the network effect, and they can form part of a dFMI.dFMI is a new concept, one that builds on the security and resilience guarantees of distributed ledger and systems engineering to provide a platform for tokenising value and transferring its ownership between participants on that or, by cross-platform exchange, on other platforms.We believe that our technology will drive adoption of a next-generation dFMI where intermediaries are removed, incentive structures encourage self-regulation, and risks are mitigated and reduced to the maximum. dFMI doesn't just provide a cryptographically secure environment for market participants to transact, it provides a peer-to-peer model that removes financial intermediaries and engenders a wider ecosystem for value transfer across platforms and pre- post-trade processes. dFMI works to mitigate concentration and liquidity risk, reduce settlement cycles to real-time, remove friction, and lower the transaction cost of economic exchange.Clearmatics is a company with a strong belief in the open source movement and good ties to the Ethereum community. We also work closely with the Ethereum Foundation, and are an active member of the Ethereum Enterprise Alliance (EEA). | $12M | Series A | Oct 10, 2018 |  |
