73 Strings Acquires Callisto, Accelerating Investment Into Agentic AI For Private Markets
The valuation technology moving private markets forward.
When capital changes hands, a valuation has to hold up and so does the data behind it. 73 Strings is the data and valuation infrastructure layer for private markets, taking portfolio data from source document to final mark with transaction grade rigor: governed data, deterministic audit-ready outputs, and full portfolio observability, built for your team and the agents that will operate it.

Trusted by the world's leading alternative asset managers
73 INTELLIGENCE
Private markets are moving faster. The infrastructure behind them has to keep up.
The bar has moved. LPs demand more. Regulators expect more. And every NAV is now, in effect, a transaction price. 73 Intelligence gives alternative asset managers the infrastructure to meet that standard: governed data, real-time portfolio intelligence, and valuations built to defend.
73 extract
Structured data from any source. Every time.
73 Extract captures and harmonizes hundreds of financial and operational data points and KPIs, turning fragmented information into structured, analysis-ready intelligence. This enables firms to respond faster to bespoke requests while supporting more informed decision-making.
73 monitor
Your entire portfolio. Observable in real time.
Live portfolio intelligence across every asset, every metric, and every reporting cycle, so your team spends less time gathering data and more time acting on it.
73 Strings has helped us digitalize and optimize our entire valuation process with a state-of-the-art, new generation solution that has delivered significant ROI across our entire operations, from valuation and compliance, to finance and controlling, and with our investment teams.

Governed AI,
built on the data layer beneath it.
Most AI in private markets is only as good as the data it runs on. That's why we built the data layer first. 73 Intelligence applies agentic AI across extraction, monitoring, and valuations, with human-in-the-loop validation, full traceability, and outputs you can put in front of an auditor.
