Best AI research and diligence platforms for private markets (2026)

Updated 4 November 2026

The right choice depends on the job. Hebbia focuses on AI document search and analysis for a firm's own knowledge. Rogo focuses on AI agents for banking and investment workflows. Arch focuses on collecting and processing alternatives documents and data. Generic AI assistants help with one-off questions. Reuben AI is living research and diligence that platforms offer to their private markets clients, kept current after delivery, with every finding linked to its evidence and a decision record from company to portfolio.

Key takeaways

/Hebbia, Rogo and Reuben AI are AI research tools; Arch is an alternatives data and document operations platform.
/Most tools help a team produce work. Reuben AI keeps research and diligence current after it is delivered.
/Reuben AI is offered by platforms to their clients, co-branded or white-label.
/Generic AI assistants rarely link each answer to checkable evidence.

Buyers comparing AI for private markets are usually asking two questions: who does the work, and does it stay true after the first answer. Document search tools speed up analysts inside one firm. Workflow agents automate parts of banking and investment tasks. Data operations tools gather statements, capital calls and reports into one place.

Reuben AI addresses a different gap. Research and diligence on companies, deals, vehicles, funds, managers and portfolios is kept current as sources change, each finding stays linked to its evidence, and committee decisions are recorded alongside the case. Platforms such as settlement providers, secondaries marketplaces and wealth managers offer it to their own clients under their brand.

Many teams use more than one of these tools. The table below shows what each is built for, based on each company's own public description.

When to choose each

Choose Hebbia when your analysts need to search and analyse a large set of your own documents and data together.

Choose Rogo when your firm wants AI agents to run parts of banking and investment workflows across its systems.

Choose Arch when the main problem is collecting statements, capital calls, quarterly reports and tax documents across many alternatives holdings.

Choose a generic AI assistant for quick, low-stakes questions where checkable evidence is not required.

Choose Reuben AI when you are a platform that wants to offer your clients research and diligence that stays current, with every finding linked to its evidence and a decision record they can rely on.

Using them together

These tools are not mutually exclusive. A wealth platform might use a data operations tool to collect holdings documents and offer Reuben AI so advisers see current research on those same holdings. An investment firm might use a document search tool internally while its platform partners deliver living research to clients.

Questions to ask any vendor

01Does the research stay current after it is delivered, and how are changes shown?
02Is each finding linked to the document and page it came from?
03Does it cover companies, deals, vehicles, funds, managers and portfolios as one linked record?
04Are committee decisions and their reasons kept with the evidence?
05Can it be offered to your clients under your brand?
