Archstone vs Formidium

Archstone is a web-based fund management platform for private capital, combining operational tools and related workflows. Its modules include a data room, LP portal, portfolio tracker, deal pipeline, cap table manager, compliance workspace, and Archie AI. Data-room links can use passwords, expiry dates, download restrictions, viewer analytics, and document version history. The LP portal supports quarterly reports, capital call notices with pro-rata calculations, and communication tracking. Portfolio tracking gathers founder updates and records ARR, burn rate, runway, headcount, and custom KPIs. Archie can answer natural-language queries, draft LP letters and investment memos, analyze pitch decks, monitor portfolio metrics, and prepare capital calls for approval. Archstone lists integrations such as QuickBooks, Xero, Google Calendar, Gmail, Stripe, Google Drive, Plaid, Affinity, Attio, and Airtable. It says data is encrypted at rest and in transit and protected by row-level security policies, but it does not hold a SOC 2 report and has not engaged an auditor. Starter begins at $297 a month; a 14-day trial is available.
