Hemrock

Hemrock is a portfolio-monitoring and fund-operations platform for venture investors, especially solo managers, SPVs and smaller funds. It is best for teams that want to shape their own reporting workflow and data environment; firms seeking a turnkey hosted system should weigh its recurring cost against the free self-hosted option.

Overview

Hemrock Portfolio turns founder updates into structured portfolio metrics and investor reporting. Teams can forward PDFs, Excel files, PowerPoint presentations or plain text; AI extracts figures and flags uncertain results for review. That can reduce the work of converting irregular updates into usable records, but flagged outputs still need human attention.

Portfolio is open source under Apache License 2.0 and can be modified and deployed for personal or commercial use. Hemrock says it is designed to run on a customer's infrastructure, database and AI keys, and that portfolio data is not shared with other funds or used to train models. That control is attractive to managers with specific data-handling preferences, while self-hosting makes them responsible for operating the environment.

Key features

• Portfolio monitoring: Charts track MRR, burn, headcount and custom KPIs over time, giving managers a way to follow company performance beyond individual update documents.
• LP reporting: Quarterly letter drafts and investor report cards provide a starting point for fund communications, rather than a finished substitute for review and editing.
• Fund accounting: Optional Fund Operations adds a double-entry ledger for funds, SPVs, direct deals or GP entities, plus period closing and a compliance calendar. It broadens the product beyond portfolio reporting for managers who want these workflows together.
• AI and data access: Users can bring keys for Anthropic, OpenAI, Google Gemini or OpenRouter, or connect local models through Ollama. A fund API and MCP server expose data and tools to scripts and AI clients, with access scoped to the relevant key or user.
• Integrations: A one-way Affinity integration imports deal and relationship data into portfolio and diligence views. Webhooks are coming soon, so teams needing broader event-driven connections may find the current integration limited.
• Deal modeling: Share-class tracking, option management, dilution scenarios and fundraising modeling support capitalization and financing workflows; multiple export formats provide ways to take data elsewhere.

Pricing

Self-hosted: free, billed Free. It includes all funds, SPVs and team members with no per-seat fees, and runs on your infrastructure. Hemrock estimates running costs at roughly $0 to $75 a month, so the software itself is free but the operating cost depends on the deployment.

Hosted: $250 a month, from $250/mo, cancel anytime. Hosting, maintenance, onboarding and ongoing support are included, along with early access. This suits funds that prefer not to operate the platform themselves, at a recurring price the free self-hosted plan avoids.

Setup and support: $2,500, paid once, from $2,500 as a one-time charge. Hemrock deploys the software on your infrastructure and includes setup, onboarding and data migration; ongoing support is available. This is a fit for teams wanting help with their own deployment rather than Hemrock-hosted operations. Email, phone and WhatsApp support is offered Monday to Friday, 9 AM to 4 PM EST.

Platforms

Hemrock supports API access, self-hosting and the web. The self-hosted route gives customers control over their operating environment, while the hosted plan removes the need to maintain that environment themselves.

Who it's for

Hemrock identifies SPVs, solo GPs and emerging managers, angels and syndicates, and micro and seed funds as its intended users. Its free, open-source portfolio product is especially compelling for lean teams able to run software on their own infrastructure. Larger firms that want extensive turnkey integrations or do not want operational responsibility should compare hosted and established administration platforms before choosing.

Pros and cons

• Pro: The Apache 2.0 license permits modification and commercial deployment, and the self-hosted plan has no per-seat fee.
• Pro: Update extraction, KPI charts and LP-report drafts connect company reporting with fund-level communication in one platform.
• Pro: Optional accounting and API/MCP access extend the product for teams that want ledger workflows or programmatic access.
• Con: The free route requires customers to run the infrastructure; estimated running costs can reach roughly $75 a month.
• Con: AI flags uncertain extracted results for review, so teams cannot treat every extracted metric as settled.
• Con: The prebuilt Affinity connection is one-way, and webhooks are not yet available.

Alternatives

For a free entry point with a hosted web and API service, consider Keel: its free plan is free for one entity and 10 active investors, with no credit card and no time limit. Hemrock instead offers all funds, SPVs and team members on its free self-hosted plan, but requires customers to run it themselves.

Verdict

Hemrock is a strong fit for emerging and smaller venture managers who want open-source portfolio reporting, optional fund accounting and control over their infrastructure. Its clearest advantage is a free, modifiable core without per-seat charges; its main caveat is that self-hosting shifts operations to the customer, while hosted service starts at $250 a month. Choose it when that balance suits your team, and look elsewhere if you need a managed system without that recurring cost or operational trade-off.
