Arch
Arch sells a private markets administration platform to family offices, registered investment advisers, individual investors, institutional allocators, accountants and service providers. It gathers capital account statements, investor letters, capital calls, tax documents and other records from funds and direct holdings into one standardized place. It then extracts the data, automates workflows and tasks, and writes AI summaries of investor letters and long documents.
Arch says it holds $539 billion of private market assets for more than 650 allocators, including four of the 20 largest global banks and eight of the 20 largest accounting firms. Its privacy policy says client data is hosted in the United States and is not given to third party AI providers for training.
MUFG Innovation Partners and Franklin Templeton joined its Series B in 2026. Arch Labs, Inc. is based in New York.

Collection, aggregation and workflow would all run without the models, which show up as summaries of investor letters and long documents. Even so, the July 2026 release calls Arch an AI platform for private markets administration.
Teams review automated results through shared permissions, whether the output is collected documents, extracted data or assigned tasks. An approval step before an automated action takes effect isn't described.
Error rates and validation methods are unpublished for both the data extraction and the AI summaries. Buyers can't gauge how often an extracted figure needs correcting before it reaches a report.
The proof offered is scale, $539 billion of private market assets held for more than 650 allocators, four of the top 20 global banks among them. Homepage testimonials carry first names only, so no client is tied to a figure.
Third party AI providers may not train on client data and may keep it for no more than 30 days. Arch reserves the right to use anonymized, aggregated data internally, a carve out allocators will want explained.
The data at stake includes tax IDs, bank account numbers and partnership tax schedules, and the privacy policy of June 30, 2026 makes Arch the customer's processor for it. Customer data is kept for up to a month after termination.
Encryption and transport layer security are described, and the trust center runs on Vanta, yet no certification or audit report is named.
Software is how Arch presents itself, and it names no regulator, rule or registration that applies to its work.
Fairness here is whether a small manager's statement is read as reliably as a large one's. Arch publishes no accuracy broken out by document type or manager, so that can't be checked.
A misread statement can put a wrong figure into a family's reporting, and Arch publishes no guarantee, indemnity or route to correct it.
Google Analytics and Intercom are the only providers named. The AI services and cloud host behind the summaries appear by category alone.
Documents arrive from funds and direct holdings, but no accounting, reporting or custody system is named as a destination for the data.
Data is hosted in the United States, with standard contractual clauses covering transfers from the EU and UK. A private deployment option doesn't appear.
Price, plan and billing unit are all unpublished, so a buyer can't tell whether cost follows assets, entities or users.
Six kinds of buyer are named, running from individual investors and family offices to accountants.
Product updates
Material product, regulatory, evidence and commercial changes at Arch, each verified against a live source and tagged to the capability axis it bears on. Funding rounds and awards are not product changes and are not logged.
Arch launched Arch Investment Research, extending its private markets platform from post commitment work into pre investment due diligence. It extracts key terms from offering materials, links each term to its source document and lets investment teams evaluate opportunities against their own criteria, and once a deal closes the diligence materials carry into ongoing monitoring. It is sold standalone or with Arch's existing data management, capital call and reporting suite, aimed at RIAs, family offices and institutional allocators.
