Hemrock

Hemrock Portfolio is an open-source platform for venture funds that turns company updates into structured metrics, dashboards, monitoring and LP reporting. Users can forward PDF, Excel, PowerPoint or plain-text updates; AI extracts metrics and flags 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 AI keys for Anthropic, OpenAI, Google Gemini and OpenRouter, as well as local models through Ollama. Designed to run on a customer’s own infrastructure, database and AI keys, it is described by Hemrock as keeping portfolio data separate from other funds and out of model training. The Apache License 2.0 permits personal or commercial use. Optional Fund Operations adds a double-entry ledger for funds, SPVs, direct deals or GP entities, plus period closing and a compliance calendar. Self-hosted use is free; Hosted starts at $250 a month, and Setup and support starts at $2,500, paid once.
