Hemrock
What it is
Hemrock Portfolio is an open-source platform for venture funds that turns company updates into metrics, dashboards, monitoring, and LP reporting. Users can forward PDFs, Excel files, PowerPoint files, or plain text; AI extracts metrics and marks uncertain results for review. The platform charts MRR, burn, headcount, and custom KPIs over time, and can draft quarterly LP letters and investor report cards. It supports user-provided keys for Anthropic, OpenAI, Google Gemini, and OpenRouter, as well as local models through Ollama. The portfolio product is designed to run on a customer's infrastructure, database, and AI keys; Hemrock says data is not shared with other funds or used to train models. Its Apache 2.0 license permits personal or commercial deployment. Optional Fund Operations adds double-entry accounting for funds, SPVs, direct deals, or GP entities, including period closing and a compliance calendar. A one-way Affinity integration imports deal and relationship data. The fund API and MCP server expose data and tools within key or user permissions. Self-hosting is free; hosted service starts at $250 a month.
