Hemrock 开源 VC 运营平台 Portfolio：自托管、自带 AI 的基金管理平台

Portfolio, by Hemrock

Manage deal flow, portfolio reporting, fund operations, LPs, and accounting, without stitching together spreadsheets and point tools.

Portfolio is an open-source operating platform for venture capital firms. Take a company from inbound screening and diligence through investment, portfolio monitoring, fund accounting, and LP reporting—all in one system. Turn on only the workflows you need, deploy on your own infrastructure, and use your own AI providers.

What it does

Portfolio gives your team one source of truth from the first look at a deal through the life of the investment. Forward founder updates, import existing data, and let AI extract the metrics, investments, and cash flows that keep portfolio dashboards and reports current.

The investment workflow classifies and fit-scores inbound opportunities, runs your diligence checklist against the data room, verifies claims with sourced external research, and drafts investment memos in your firm's structure and voice.

Fund operations run on real double-entry books that keep themselves: every entity has its ledger from the day it is created, and recording an investment, a mark, an exit or a capital call posts it — so capital accounts, statements, carry and LP reporting flow from the books whether or not anyone opens the accounting pages. Turn on the views you need, when you need them. A secure LP portal delivers statements, letters, and fund documents and records engagement.

How it works

Portfolio Reporting — Forward investor updates in any format or import existing spreadsheets. AI identifies each company, extracts metrics, investments, and cash flows, and sends uncertain results to a review queue. Track custom KPIs, valuations, proceeds, TVPI, DPI, and Net IRR in current dashboards.
Investment Workflow — Classify and thesis-score inbound pitches, manage the deal pipeline, run your diligence checklist against uploaded data rooms, verify claims through sourced external research, and draft an investment memo in your firm's voice with paragraph-level provenance.
LP Reporting — Track commitments, paid-in capital, distributions, and NAV across vehicles as dated positions; generate statements and quarterly letters; and deliver reports and documents through a secure, fund-branded LP portal with engagement tracking.
Fund Operations — Double-entry books for every entity, kept as you record investments and capital calls; import bank activity, run monthly closes, maintain partner capital accounts, model management fees and carried interest, budget and forecast each entity, and track compliance obligations.
Your AI, your data — Connect Claude or ChatGPT to your own deployment over MCP with a plugin built for your address. Ask "what can you do?" for a home dashboard of what you can open and what to ask; open live portfolio, company, statement, LP capital and capital-call dashboards inside the conversation (who has paid, who says they wired, who still owes) and save them; pick ready-made prompts like Quarter-end review from the prompt menu; and get an LP's capital account statement or report card as a PDF link — every answer scoped to the access of the person signed in.
AI Analyst and CRM — Ask questions grounded in your fund's actual data, compare companies, surface trends, share Notes with your team, and log conversations and introductions through your inbound address.
Access by entity and by area — Grant each team member the funds, SPVs and entities they work on, and the areas (portfolio, accounting, LP capital, carry…) they may read or edit. Enforced at the API, on every page and in the database.
Modular and self-hosted — Enable only the workflows you use, add all of your funds, SPVs, and team members without per-seat fees, and install the fund-branded app on a phone.

Why you should use this

Data consistency and availability - One source of truth for your team. Reduce your reliance on a maze of spreadsheets. Everyone works from the same portfolio data, metrics, and reports from a central location.
Built to work with AI - Bring your fund data to your own AI, and use it to ask anything about your portfolio and fund. Ask about benchmarks, trends, industry data, research, and more.
Professionalize internal operations - Institutional-quality reporting infrastructure without the cost of enterprise software. Run it yourself, on your own terms.
Built for how funds work - Designed by a fund CFO for key workflows, including investor updates, LP reporting, and portfolio monitoring. Works alongside your fund admin and operations team.

Why this exists

I've spent over a decade as a fund CFO, investor, and consultant — working with thousands of GPs and founders on the exact problem this tool solves: manually collecting, analyzing, and presenting portfolio data every quarter.

Most portfolio reporting platforms lock your data in their database, process it through their AI, and charge per seat so half your team can't log in. Fund managers shouldn't have to choose between good tooling and owning their data.

This is a complete investment-firm operations platform you deploy on your own infrastructure — your database, your AI keys, your domain. It's open source under the Apache 2.0 license: free to use, modify, and run forever, for your own fund or commercially. No per-seat fees. No black-box AI training on your portfolio. No vendor lock-in.
