Juniper Square

Juniper Square is a fund operating system for the private markets, used by 2,300+ general partners across private equity, venture capital, commercial real estate, and private credit to raise capital, run fund administration and fund accounting, and manage the LP experience. Its GPX platform unifies investor data, fund accounting, payments, compliance, and reporting, and exposes them through a developer API (broad read/write coverage delivered as a developer-led engagement), pre-built connectors (HubSpot, Preqin, Outlook, DocuSign, Yardi IM/Voyager, Lob), and Headless GPX — an MCP server that brings the platform to any MCP-compatible AI client (Claude, Copilot, ChatGPT, Gemini) with authentication, permissions, and audit inherited from the customer's existing configuration.

Juniper Square publishes 1 API on the APIs.io network. Tagged areas include Company, Investment Management, Private Markets, Fund Administration, and Fund Accounting.

Juniper Square’s developer surface includes engineering blog, documentation, support, and 14 more developer resources.
