[Spark CEO: Sub-DAOs as a Solution to Governance Issues] According to Cryptobriefing, Spark Protocol CEO Sam Macpherson has proposed the sub-DAO governance model as a solution to the challenges of flat DAO governance. Macpherson believes that in flat DAOs, every major decision must go through the same governance process, leading to slow decision-making, voter fatigue, and the formation of political factions. The sub-DAO model does not suppress governance competition but instead channels it in a productive direction—where the core DAO sets high-level rules, and sub-DAOs independently handle operational decisions (such as lending markets, risk management, and capital deployment), proving their value through outcomes rather than governance votes.
