Blockhouse provides brokerage and custody infrastructure for private securities and alternative assets. Its platform helps broker-dealers and RIAs manage client investments in alternatives—such as private equity, private credit, real estate, and venture capital—through electronic subscriptions, consolidated reporting, and secure custody. The system handles onboarding, digital processing, and unified reporting, giving advisors and clients a single view of alternative asset data, and it is FINRA-registered and SIPC member for asset safety. The company aims to modernize private markets by replacing paper-based processes and making alternative investments easier to access, transparent, and efficiently managed for advisors and their clients.

Simplify's Take

What believers are saying

  • Alternative asset AUM growth drives demand for modernized infrastructure and compliance automation.
  • RIA market expansion creates TAM for platforms simplifying private equity and venture capital access.
  • Regulatory tailwinds incentivize broker-dealers to adopt qualified custodian partnerships like Blockhouse's.

What critics are saying

  • Carta XN automates Form D filings and cap table management, undercutting Blockhouse's subscriptions.
  • SS&C's HiPortfolio acquisition bundles custody with reporting, creating superior integrated competitor.
  • Forge Global's secondary trading APIs bypass Blockhouse's brokerage layer for direct RIA access.

What makes Blockhouse unique

  • FINRA broker-dealer and SIPC member providing regulated custody for alternative assets.
  • Digital infrastructure streamlines private securities transactions historically fragmented across paper processes.
  • Integrated platform consolidates subscriptions, reporting, and custody eliminating multi-vendor complexity.
