Blockhouse

Brokerage and custody for private alternatives

Overview

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

  • Antler backed Blockhouse in September 2025, validating the team and product direction.
  • February-May 2026 blog cadence shows active shipping: connectivity, execution, and risk tooling.
  • June 2026 site positioning targets frontier-market quant demand with custody-preserving automation.

What critics are saying

  • Antler listed only $200,000 pre-seed in May 2025; capital remains extremely thin.
  • Crypto custody and managed-account rules can reclassify Blockhouse as a regulated custodian.
  • Exchange outages, revoked APIs, or liquidation losses can destroy trust instantly.

What makes Blockhouse unique

  • Non-custodial SMA architecture keeps client custody while Blockhouse executes trades through API keys.
  • May 2026 margin-management server monitors PLD across venues in real time.
  • June 2026 website pitches zero-knowledge key access and whitelisted accounts for institutional workflows.
