Polymarket founder and CEO Shayne Coplan announced that former Zora CEO Jacob Horne has joined the prediction market platform to lead product development with a focus on enhancing its DeFi business. Coplan acknowledged that on-chain product performance has declined as the platform scaled, noting user dissatisfaction and the need to integrate different products more effectively. Horne will work directly with Coplan to drive these improvements as Polymarket prepares to host an upcoming DeFi online meeting. The session aims to gather community feedback and announce specific plans for product upgrades and integration.
