In their own words
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.
Mantle
Mantle is a web-based cap table management platform from Mantle Equity for startups. It tracks share classes and securities such as SAFEs, preferred stock, warrants, and RSAs, and supports option management. Mantle says its AI can read SAFEs, notes, term sheets, and other documents to help create an audit-ready cap table. Users can model fundraising rounds, dilution, and option pools against their real-time cap table, then download a cap table in Open Cap Table Format (OCX). Built-in digital signatures support issuing grants and agreements. Customers can add counsel and other stakeholders without per-seat pricing, and plans include unlimited stakeholders. Starter is free and includes SAFE signing and templates, vesting schedules, scenario modeling, law firm integration, and cap table exports. Essentials costs $1,200 a year; Growth costs $3,000 a year and adds an annual 409A valuation and VIP customer support. Growth+ has no listed price. Mantle states that it complies with AICPA SOC 2 Type II standards, hosts its platform on Google Cloud in the US Central region, and uses 256-bit TLS encryption for information moving over the internet.
